This library provides smart pointers and collections for managing\n\/\/! heap-allocated values.\n\/\/!\n\/\/! This library, like libcore, is not intended for general usage, but rather as\n\/\/! a building block of other libraries. The types and interfaces in this\n\/\/! library are re-exported through the [standard library](..\/std\/index.html),\n\/\/! and should not be used through this library.\n\/\/!\n\/\/! ## Boxed values\n\/\/!\n\/\/! The [`Box`](boxed\/index.html) type is a smart pointer type. There can\n\/\/! only be one owner of a `Box`, and the owner can decide to mutate the\n\/\/! contents, which live on the heap.\n\/\/!\n\/\/! This type can be sent among threads efficiently as the size of a `Box` value\n\/\/! is the same as that of a pointer. Tree-like data structures are often built\n\/\/! with boxes because each node often has only one owner, the parent.\n\/\/!\n\/\/! ## Reference counted pointers\n\/\/!\n\/\/! The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a thread. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](arc\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This type allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Collections\n\/\/!\n\/\/! Implementations of the most common general purpose data structures are\n\/\/! defined in this library. They are re-exported through the\n\/\/! [standard collections library](..\/std\/collections\/index.html).\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/! The [`alloc`](alloc\/index.html) module defines the low-level interface to the\n\/\/! default global allocator. It is not compatible with the libc allocator API.\n\n#![allow(unused_attributes)]\n#![unstable(feature = \"alloc\",\n            reason = \"this library is unlikely to be stabilized in its current \\\n                      form or name\",\n            issue = \"27783\")]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       issue_tracker_base_url = \"https:\/\/github.com\/rust-lang\/rust\/issues\/\",\n       test(no_crate_inject, attr(allow(unused_variables), deny(warnings))))]\n#![no_std]\n#![needs_allocator]\n#![deny(missing_debug_implementations)]\n\n#![cfg_attr(test, allow(deprecated))] \/\/ rand\n#![cfg_attr(not(test), feature(exact_size_is_empty))]\n#![cfg_attr(not(test), feature(generator_trait))]\n#![cfg_attr(test, feature(rand, test))]\n#![feature(allocator_api)]\n#![feature(allow_internal_unstable)]\n#![feature(arbitrary_self_types)]\n#![feature(ascii_ctype)]\n#![feature(box_into_raw_non_null)]\n#![feature(box_patterns)]\n#![feature(box_syntax)]\n#![feature(cfg_target_has_atomic)]\n#![feature(coerce_unsized)]\n#![feature(collections_range)]\n#![feature(const_fn)]\n#![feature(core_intrinsics)]\n#![feature(custom_attribute)]\n#![feature(dropck_eyepatch)]\n#![feature(exact_size_is_empty)]\n#![feature(fmt_internals)]\n#![feature(from_ref)]\n#![feature(fundamental)]\n#![feature(futures_api)]\n#![feature(lang_items)]\n#![feature(libc)]\n#![feature(needs_allocator)]\n#![feature(optin_builtin_traits)]\n#![feature(pattern)]\n#![feature(pin)]\n#![feature(ptr_internals)]\n#![feature(ptr_offset_from)]\n#![cfg_attr(stage0, feature(repr_transparent))]\n#![feature(rustc_attrs)]\n#![feature(specialization)]\n#![feature(split_ascii_whitespace)]\n#![feature(staged_api)]\n#![feature(str_internals)]\n#![feature(trusted_len)]\n#![feature(try_reserve)]\n#![feature(unboxed_closures)]\n#![feature(unicode_internals)]\n#![feature(unsize)]\n#![feature(allocator_internals)]\n#![feature(on_unimplemented)]\n#![feature(exact_chunks)]\n#![feature(pointer_methods)]\n#![feature(inclusive_range_methods)]\n#![feature(rustc_const_unstable)]\n#![feature(const_vec_new)]\n\n#![cfg_attr(not(test), feature(fn_traits, i128))]\n#![cfg_attr(test, feature(test))]\n\n\/\/ Allow testing this library\n\n#[cfg(test)]\n#[macro_use]\nextern crate std;\n#[cfg(test)]\nextern crate test;\n#[cfg(test)]\nextern crate rand;\n\n\/\/ Module with internal macros used by other modules (needs to be included before other modules).\n#[macro_use]\nmod macros;\n\n#[rustc_deprecated(since = \"1.27.0\", reason = \"use the heap module in core, alloc, or std instead\")]\n#[unstable(feature = \"allocator_api\", issue = \"32838\")]\n\/\/\/ Use the `alloc` module instead.\npub mod allocator {\n    pub use alloc::*;\n}\n\n\/\/ Heaps provided for low-level allocation strategies\n\npub mod alloc;\n\n#[unstable(feature = \"futures_api\",\n           reason = \"futures in libcore are unstable\",\n           issue = \"50547\")]\npub mod task;\n\/\/ Primitive types using the heaps above\n\n\/\/ Need to conditionally define the mod from `boxed.rs` to avoid\n\/\/ duplicating the lang-items when building in test cfg; but also need\n\/\/ to allow code to have `use boxed::Box;` declarations.\n#[cfg(not(test))]\npub mod boxed;\n#[cfg(test)]\nmod boxed {\n    pub use std::boxed::Box;\n}\n#[cfg(test)]\nmod boxed_test;\n#[cfg(target_has_atomic = \"ptr\")]\npub mod arc;\npub mod rc;\npub mod raw_vec;\n\n\/\/ collections modules\npub mod binary_heap;\nmod btree;\npub mod borrow;\npub mod fmt;\npub mod linked_list;\npub mod slice;\npub mod str;\npub mod string;\npub mod vec;\npub mod vec_deque;\n\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub mod btree_map {\n    \/\/!

This macro can handle either named\n\/\/\/ structs or tuple structs. It does not handle unit structs.\n\/\/\/\n\/\/\/ When calling this macro from the outside, it takes three arguments. The\n\/\/\/ first is a single token tree of passthrough information, which will be given\n\/\/\/ to the callback unchanged. The second is the name of the macro to call with\n\/\/\/ the parsed field. The third is the *entire* body of the struct, including\n\/\/\/ either the curly braces or parens.\n\/\/\/\n\/\/\/ If a tuple struct is given, all fields *must* be annotated with\n\/\/\/ `#[column_name(name)]`. Due to the nature of non-procedural macros, we\n\/\/\/ cannot give a helpful error message in this case.\n\/\/\/\n\/\/\/ The callback will be called with the given headers, and a list of fields\n\/\/\/ in record form with the following properties:\n\/\/\/\n\/\/\/ - `field_name` is the name of the field on the struct. This will not be\n\/\/\/   present if the struct is a tuple struct.\n\/\/\/ - `column_name` is the column the field corresponds to. This will either be\n\/\/\/   the value of a `#[column_name]` attribute on the field, or the field name\n\/\/\/   if not present.\n\/\/\/ - `field_type` is the type of the field on the struct.\n\/\/\/ - `field_kind` Will be either `regular` or `option` depending on whether\n\/\/\/   the type of the field was an option or not.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ If this macro is called with:\n\/\/\/\n\/\/\/ ```ignore\n\/\/\/ __diesel_parse_struct_body {\n\/\/\/     (my original arguments),\n\/\/\/     callback = my_macro,\n\/\/\/     body = {\n\/\/\/         pub foo: i32,\n\/\/\/         bar: Option<i32>,\n\/\/\/         #[column_name(other)]\n\/\/\/         baz: String,\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ Then the resulting expansion will be:\n\/\/\/\n\/\/\/ ```ignore\n\/\/\/ my_macro! {\n\/\/\/     (my original arguments),\n\/\/\/     fields = [{\n\/\/\/         field_name: foo,\n\/\/\/         column_name: foo,\n\/\/\/         field_ty: i32,\n\/\/\/         field_kind: regular,\n\/\/\/     }, {\n\/\/\/         field_name: bar,\n\/\/\/         column_name: bar,\n\/\/\/         field_ty: Option<i32>,\n\/\/\/         field_kind: option,\n\/\/\/     }, {\n\/\/\/         field_name: baz,\n\/\/\/         column_name: other,\n\/\/\/         field_ty: String,\n\/\/\/         field_kind: regular,\n\/\/\/     }],\n\/\/\/ }\n#[macro_export]\n#[doc(hidden)]\nmacro_rules! __diesel_parse_struct_body {\n    \/\/ Entry point for named structs\n    (\n        $headers:tt,\n        callback = $callback:ident,\n        body = {$($body:tt)*},\n    ) => {\n        __diesel_parse_struct_body! {\n            $headers,\n            callback = $callback,\n            fields = [],\n            body = ($($body)*,),\n        }\n    };\n\n    \/\/ Entry point for tuple structs\n    (\n        $headers:tt,\n        callback = $callback:ident,\n        body = ($($body:tt)*),\n    ) => {\n        __diesel_parse_struct_body! {\n            $headers,\n            callback = $callback,\n            fields = [],\n            body = ($($body)*,),\n        }\n    };\n\n    \/\/ FIXME: Replace with `vis` specifier if relevant RFC lands\n    \/\/ First, strip `pub` if it exists\n    (\n        $headers:tt,\n        callback = $callback:ident,\n        fields = $fields:tt,\n        body = (\n            $(#$meta:tt)*\n            pub $($tail:tt)*),\n    ) => {\n        __diesel_parse_struct_body! {\n            $headers,\n            callback = $callback,\n            fields = $fields,\n            body = ($(#$meta)* $($tail)*),\n        }\n    };\n\n    \/\/ Since we blindly add a comma to the end of the body, we might have a\n    \/\/ double trailing comma.

The Clone trait for types that cannot be \"implicitly copied\"\n\nIn Rust, some simple types are \"implicitly copyable\" and when you\nassign them or pass them as arguments, the receiver will get a copy,\nleaving the original value in place. These types do not require\nallocation to copy and do not have finalizers (i.e. they do not\ncontain owned boxes or implement `Drop`), so the compiler considers\nthem cheap and safe to copy and automatically implements the `Copy`\ntrait for them. For other types copies must be made explicitly,\nby convention implementing the `Clone` trait and calling the\n`clone` method.\n\n*\/\n\nuse core::kinds::Const;\n\npub trait Clone {\n    \/\/\/ Return a deep copy of the owned object tree.

Composable internal iterators\n\nInternal iterators are functions implementing the protocol used by the `for` loop.\n\nAn internal iterator takes `fn(...) -> bool` as a parameter, with returning `false` used to signal\nbreaking out of iteration.

For example:\n\n~~~ {.rust}\nprintln(iter::to_vec(|f| uint::range(0, 20, f)).to_str());\n~~~\n\nAn external iterator object implementing the interface in the `iterator` module can be used as an\ninternal iterator by calling the `advance` method.

Calculation and management of a Strict Version Hash for crates\n\/\/!\n\/\/! # Today's ABI problem\n\/\/!\n\/\/! In today's implementation of rustc, it is incredibly difficult to achieve\n\/\/! forward binary compatibility without resorting to C-like interfaces. Within\n\/\/! rust code itself, abi details such as symbol names suffer from a variety of\n\/\/! unrelated factors to code changing such as the \"def id drift\" problem. This\n\/\/! ends up yielding confusing error messages about metadata mismatches and\n\/\/! such.\n\/\/!\n\/\/! The core of this problem is when an upstream dependency changes and\n\/\/! downstream dependents are not recompiled. This causes compile errors because\n\/\/! the upstream crate's metadata has changed but the downstream crates are\n\/\/! still referencing the older crate's metadata.\n\/\/!\n\/\/! This problem exists for many reasons, the primary of which is that rust does\n\/\/! not currently support forwards ABI compatibility (in place upgrades of a\n\/\/! crate).\n\/\/!\n\/\/! # SVH and how it alleviates the problem\n\/\/!\n\/\/! With all of this knowledge on hand, this module contains the implementation\n\/\/! of a notion of a \"Strict Version Hash\" for a crate. This is essentially a\n\/\/! hash of all contents of a crate which can somehow be exposed to downstream\n\/\/! crates.\n\/\/!\n\/\/! This hash is currently calculated by just hashing the AST, but this is\n\/\/! obviously wrong (doc changes should not result in an incompatible ABI).\n\/\/! Implementation-wise, this is required at this moment in time.\n\/\/!\n\/\/! By encoding this strict version hash into all crate's metadata, stale crates\n\/\/! can be detected immediately and error'd about by rustc itself.\n\/\/!\n\/\/! # Relevant links\n\/\/!\n\/\/!

Calculation and management of a Strict Version Hash for crates\n\/\/!\n\/\/! # Today's ABI problem\n\/\/!\n\/\/! In today's implementation of rustc, it is incredibly difficult to achieve\n\/\/! forward binary compatibility without resorting to C-like interfaces. Within\n\/\/! rust code itself, abi details such as symbol names suffer from a variety of\n\/\/! unrelated factors to code changing such as the \"def id drift\" problem. This\n\/\/! ends up yielding confusing error messages about metadata mismatches and\n\/\/! such.\n\/\/!\n\/\/! The core of this problem is when an upstream dependency changes and\n\/\/! downstream dependents are not recompiled. This causes compile errors because\n\/\/! the upstream crate's metadata has changed but the downstream crates are\n\/\/! still referencing the older crate's metadata.\n\/\/!\n\/\/! This problem exists for many reasons, the primary of which is that rust does\n\/\/! not currently support forwards ABI compatibility (in place upgrades of a\n\/\/! crate).\n\/\/!\n\/\/! # SVH and how it alleviates the problem\n\/\/!\n\/\/! With all of this knowledge on hand, this module contains the implementation\n\/\/! of a notion of a \"Strict Version Hash\" for a crate. This is essentially a\n\/\/! hash of all contents of a crate which can somehow be exposed to downstream\n\/\/! crates.\n\/\/!\n\/\/! This hash is currently calculated by just hashing the AST, but this is\n\/\/! obviously wrong (doc changes should not result in an incompatible ABI).\n\/\/! Implementation-wise, this is required at this moment in time.\n\/\/!\n\/\/! By encoding this strict version hash into all crate's metadata, stale crates\n\/\/! can be detected immediately and error'd about by rustc itself.\n\/\/!\n\/\/! # Relevant links\n\/\/!\n\/\/!

Liveness analysis which computes liveness of MIR local variables at the boundary of basic blocks\n\/\/!\n\/\/! This analysis considers references as being used only at the point of the\n\/\/! borrow. This means that this does not track uses because of references that\n\/\/! already exist:\n\/\/!\n\/\/! ```Rust\n\/\/!     fn foo() {\n\/\/!         x = 0;\n\/\/!         \/\/ `x` is live here\n\/\/!

OTHER_GLOBAL = &x: *const u32;\n\/\/!         \/\/ ...\n\/\/!     }\n\/\/! ```\n\/\/!\n\/\/! This means that users of this analysis still have to check whether\n\/\/! pre-existing references can be used to access the value (e.g. at movable\n\/\/! generator yield points, all pre-existing references are invalidated, so this\n\/\/! doesn't matter).\n\nuse rustc::mir::*;\nuse rustc::mir::visit::{LvalueContext, Visitor};\nuse rustc_data_structures::indexed_vec::{IndexVec, Idx};\nuse rustc_data_structures::indexed_set::IdxSetBuf;\nuse util::pretty::{write_basic_block, dump_enabled, write_mir_intro};\nuse rustc::mir::transform::MirSource;\nuse rustc::ty::item_path;\nuse std::path::{PathBuf, Path};\nuse std::fs;\nuse rustc::ty::TyCtxt;\nuse std::io::{self, Write};\n\npub type LocalSet = IdxSetBuf<Local>;\n\n#[derive(Eq, PartialEq, Clone)]\nstruct BlockInfo {\n    defs: LocalSet,\n    uses: LocalSet,\n}\n\nstruct BlockInfoVisitor {\n    defs: LocalSet,\n    uses: LocalSet,\n}\n\nimpl BlockInfoVisitor {\n    fn add_def(&mut self, index: Local) {\n        \/\/ If it was used already in the block, remove that use\n        \/\/ now that we found a definition.\n        \/\/\n        \/\/ Example:\n        \/\/\n        \/\/     \/\/ Defs = {X}, Uses = {}\n        \/\/     X = 5\n        \/\/     \/\/ Defs = {}, Uses = {X}\n        \/\/     use(X)\n        self.uses.remove(&index);\n        self.defs.add(&index);\n    }\n\n    fn add_use(&mut self, index: Local) {\n        \/\/ Inverse of above.\n        \/\/\n        \/\/ Example:\n        \/\/\n        \/\/     \/\/ Defs = {}, Uses = {X}\n        \/\/     use(X)\n        \/\/     \/\/ Defs = {X}, Uses = {}\n        \/\/     X = 5\n        \/\/     \/\/ Defs = {}, Uses = {X}\n        \/\/     use(X)\n        self.defs.remove(&index);\n        self.uses.add(&index);\n    }\n}\n\nimpl<'tcx> Visitor<'tcx> for BlockInfoVisitor {\n    fn visit_local(&mut self,\n                   &local: &Local,\n                   context: LvalueContext<'tcx>,\n                   _: Location) {\n        match context {\n            \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\n            \/\/ DEFS\n\n            LvalueContext::Store |\n\n            \/\/ We let Call defined the result in both the success and\n            \/\/ unwind cases.

Liveness analysis which computes liveness of MIR local variables at the boundary of basic blocks\n\/\/!\n\/\/! This analysis considers references as being used only at the point of the\n\/\/! borrow.

OTHER_GLOBAL = &x: *const u32;\n\/\/!         \/\/ ...\n\/\/!     }\n\/\/! ```\n\/\/!\n\/\/!

A pointer type for heap allocation.\n\/\/!\n\/\/! `Box<T>`, casually referred to as a 'box', provides the simplest form of heap allocation in\n\/\/! Rust. Boxes provide ownership for this allocation, and drop their contents when they go out of\n\/\/! scope.\n\/\/!\n\/\/! Boxes are useful in two situations: recursive data structures, and occasionally when returning\n\/\/! data. [The Pointer chapter of the Book](..\/..\/..\/book\/pointers.html#best-practices-1) explains\n\/\/! these cases in detail.\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! Creating a box:\n\/\/!\n\/\/! ```\n\/\/! let x = Box::new(5);\n\/\/! ```\n\/\/!\n\/\/! Creating a recursive data structure:\n\/\/!\n\/\/! ```\n\/\/! #[derive(Show)]\n\/\/! enum List<T> {\n\/\/!     Cons(T, Box<List<T>>),\n\/\/!     Nil,\n\/\/! }\n\/\/!\n\/\/! fn main() {\n\/\/!     let list: List<i32> = List::Cons(1, Box::new(List::Cons(2, Box::new(List::Nil))));\n\/\/!     println!(\"{:?}\", list);\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! This will print `Cons(1i32, Box(Cons(2i32, Box(Nil))))`.\n\n#![stable]\n\nuse core::any::Any;\nuse core::clone::Clone;\nuse core::cmp::{PartialEq, PartialOrd, Eq, Ord, Ordering};\nuse core::default::Default;\nuse core::error::{Error, FromError};\nuse core::fmt;\nuse core::hash::{self, Hash};\nuse core::iter::Iterator;\nuse core::marker::Sized;\nuse core::mem;\nuse core::ops::{Deref, DerefMut};\nuse core::option::Option;\nuse core::ptr::Unique;\nuse core::raw::TraitObject;\nuse core::result::Result::{Ok, Err};\nuse core::result::Result;\n\n\/\/\/ A value that represents the heap.

(self.num - other.num).abs() < 5\n\/\/!     }\n\/\/! }\n\/\/!\n\/\/! \/\/ Now these binary operators will work when applied!\n\/\/! assert!(SketchyNum {num: 37} == SketchyNum {num: 34});\n\/\/! assert!(SketchyNum {num: 25} != SketchyNum {num: 57});\n\/\/! ```\n\n\/\/\/ Trait for values that can be compared for equality and inequality.\n\/\/\/\n\/\/\/ This trait allows partial equality, where types can be unordered instead of\n\/\/\/ strictly equal or unequal. For example, with the built-in floating-point\n\/\/\/ types `a == b` and `a != b` will both evaluate to false if either `a` or\n\/\/\/ `b` is NaN (cf. IEEE 754-2008 section 5.11).\n\/\/\/\n\/\/\/ Eq only requires the `eq` method to be implemented; `ne` is its negation by\n\/\/\/ default.\n\/\/\/\n\/\/\/ Eventually, this will be implemented by default for types that implement\n\/\/\/ `TotalEq`.\n#[lang=\"eq\"]\npub trait Eq {\n    \/\/\/ This method tests for `self` and `other` values to be equal, and is used by `==`.\n    fn eq(&self, other: &Self) -> bool;\n\n    \/\/\/ This method tests for `!=`.\n    #[inline]\n    fn ne(&self, other: &Self) -> bool { !self.eq(other) }\n}\n\n\/\/\/ Trait for equality comparisons which are [equivalence relations](\n\/\/\/ https:\/\/en.wikipedia.org\/wiki\/Equivalence_relation).\n\/\/\/\n\/\/\/ This means, that in addition to `a == b` and `a != b` being strict\n\/\/\/ inverses, the equality must be (for all `a`, `b` and `c`):\n\/\/\/\n\/\/\/ - reflexive: `a == a`;\n\/\/\/ - symmetric: `a == b` implies `b == a`; and\n\/\/\/ - transitive: `a == b` and `b == c` implies `a == c`.\npub trait TotalEq: Eq {\n    \/\/ FIXME #13101: this method is used solely by #[deriving] to\n    \/\/ assert that every component of a type implements #[deriving]\n    \/\/ itself, the current deriving infrastructure means doing this\n    \/\/ assertion without using a method on this trait is nearly\n    \/\/ impossible.\n    \/\/\n    \/\/ This should never be implemented by hand.\n    #[doc(hidden)]\n    #[inline(always)]\n    fn assert_receiver_is_total_eq(&self) {}\n}\n\n\/\/\/ A macro which defines an implementation of TotalEq for a given type.\nmacro_rules! totaleq_impl(\n    ($t:ty) => {\n        impl TotalEq for $t {}\n    }\n)\n\ntotaleq_impl!(bool)\n\ntotaleq_impl!(u8)\ntotaleq_impl!(u16)\ntotaleq_impl!(u32)\ntotaleq_impl!(u64)\n\ntotaleq_impl!(i8)\ntotaleq_impl!(i16)\ntotaleq_impl!(i32)\ntotaleq_impl!(i64)\n\ntotaleq_impl!(int)\ntotaleq_impl!(uint)\n\ntotaleq_impl!(char)\n\n\/\/\/ An ordering is, e.g, a result of a comparison between two values.\n#[deriving(Clone, Eq, Show)]\npub enum Ordering {\n   \/\/\/ An ordering where a compared value is less [than another].\n   Less = -1,\n   \/\/\/ An ordering where a compared value is equal [to another].\n   Equal = 0,\n   \/\/\/ An ordering where a compared value is greater [than another].\n   Greater = 1\n}\n\n\/\/\/ Trait for types that form a [total order](\n\/\/\/ https:\/\/en.wikipedia.org\/wiki\/Total_order).\n\/\/\/\n\/\/\/ An order is a total order if it is (for all `a`, `b` and `c`):\n\/\/\/\n\/\/\/ - total and antisymmetric: exactly one of `a < b`, `a == b` or `a > b` is\n\/\/\/   true; and\n\/\/\/ - transitive, `a < b` and `b < c` implies `a < c`.

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/! Utilities related to FFI bindings.\n\/\/!\n\/\/! This module provides utilities to handle data across non-Rust\n\/\/! interfaces, like other programming languages and the underlying\n\/\/! operating system. It is mainly of use for FFI (Foreign Function\n\/\/! Interface) bindings and code that needs to exchange C-like strings\n\/\/! with other languages.\n\/\/!\n\/\/! # Overview\n\/\/!\n\/\/! Rust represents owned strings with the [`String`] type, and\n\/\/! borrowed slices of strings with the [`str`] primitive. Both are\n\/\/! always in UTF-8 encoding, and may contain nul bytes in the middle,\n\/\/! i.e. if you look at the bytes that make up the string, there may\n\/\/! be a `\\0` among them. Both `String` and `str` store their length\n\/\/! explicitly; there are no nul terminators at the end of strings\n\/\/! like in C.\n\/\/!\n\/\/! C strings are different from Rust strings:\n\/\/!\n\/\/! * **Encodings** - Rust strings are UTF-8, but C strings may use\n\/\/! other encodings. If you are using a string from C, you should\n\/\/! check its encoding explicitly, rather than just assuming that it\n\/\/! is UTF-8 like you can do in Rust.\n\/\/!\n\/\/! * **Character size** - C strings may use `char` or `wchar_t`-sized\n\/\/! characters; please **note** that C's `char` is different from Rust's.\n\/\/! The C standard leaves the actual sizes of those types open to\n\/\/! interpretation, but defines different APIs for strings made up of\n\/\/! each character type. Rust strings are always UTF-8, so different\n\/\/! Unicode characters will be encoded in a variable number of bytes\n\/\/! each. The Rust type [`char`] represents a '[Unicode scalar\n\/\/! value]', which is similar to, but not the same as, a '[Unicode\n\/\/! code point]'.\n\/\/!\n\/\/! * **Nul terminators and implicit string lengths** - Often, C\n\/\/! strings are nul-terminated, i.e. they have a `\\0` character at the\n\/\/! end. The length of a string buffer is not stored, but has to be\n\/\/! calculated; to compute the length of a string, C code must\n\/\/! manually call a function like `strlen()` for `char`-based strings,\n\/\/! or `wcslen()` for `wchar_t`-based ones. Those functions return\n\/\/! the number of characters in the string excluding the nul\n\/\/! terminator, so the buffer length is really `len+1` characters.\n\/\/! Rust strings don't have a nul terminator; their length is always\n\/\/! stored and does not need to be calculated. While in Rust\n\/\/! accessing a string's length is a O(1) operation (because the\n\/\/! length is stored); in C it is an O(length) operation because the\n\/\/! length needs to be computed by scanning the string for the nul\n\/\/! terminator.\n\/\/!\n\/\/! * **Internal nul characters** - When C strings have a nul\n\/\/! terminator character, this usually means that they cannot have nul\n\/\/! characters in the middle — a nul character would essentially\n\/\/! truncate the string. Rust strings *can* have nul characters in\n\/\/! the middle, because nul does not have to mark the end of the\n\/\/! string in Rust.\n\/\/!\n\/\/! # Representations of non-Rust strings\n\/\/!\n\/\/! [`CString`] and [`CStr`] are useful when you need to transfer\n\/\/! UTF-8 strings to and from languages with a C ABI, like Python.\n\/\/!\n\/\/! * **From Rust to C:** [`CString`] represents an owned, C-friendly\n\/\/! string: it is nul-terminated, and has no internal nul characters.\n\/\/! Rust code can create a `CString` out of a normal string (provided\n\/\/! that the string doesn't have nul characters in the middle), and\n\/\/! then use a variety of methods to obtain a raw `*mut u8` that can\n\/\/! then be passed as an argument to functions which use the C\n\/\/! conventions for strings.\n\/\/!\n\/\/! * **From C to Rust:** [`CStr`] represents a borrowed C string; it\n\/\/! is what you would use to wrap a raw `*const u8` that you got from\n\/\/! a C function. A `CStr` is guaranteed to be a nul-terminated array\n\/\/! of bytes. Once you have a `CStr`, you can convert it to a Rust\n\/\/! `&str` if it's valid UTF-8, or lossily convert it by adding\n\/\/! replacement characters.\n\/\/!\n\/\/! [`OsString`] and [`OsStr`] are useful when you need to transfer\n\/\/! strings to and from the operating system itself, or when capturing\n\/\/! the output of external commands. Conversions between `OsString`,\n\/\/! `OsStr` and Rust strings work similarly to those for [`CString`]\n\/\/! and [`CStr`].\n\/\/!\n\/\/! * [`OsString`] represents an owned string in whatever\n\/\/! representation the operating system prefers. In the Rust standard\n\/\/! library, various APIs that transfer strings to\/from the operating\n\/\/! system use `OsString` instead of plain strings. For example,\n\/\/! [`env::var_os()`] is used to query environment variables; it\n\/\/! returns an `Option<OsString>`. If the environment variable exists\n\/\/! you will get a `Some(os_string)`, which you can *then* try to\n\/\/! convert to a Rust string. This yields a [`Result<>`], so that\n\/\/! your code can detect errors in case the environment variable did\n\/\/! not in fact contain valid Unicode data.\n\/\/!\n\/\/! * [`OsStr`] represents a borrowed reference to a string in a\n\/\/! format that can be passed to the operating system. It can be\n\/\/! converted into an UTF-8 Rust string slice in a similar way to\n\/\/! `OsString`.\n\/\/!\n\/\/! # Conversions\n\/\/!\n\/\/! ## On Unix\n\/\/!\n\/\/! On Unix, [`OsStr`] implements the\n\/\/! `std::os::unix::ffi::`[`OsStrExt`][unix.OsStrExt] trait, which\n\/\/! augments it with two methods, [`from_bytes`] and [`as_bytes`].\n\/\/! These do inexpensive conversions from and to UTF-8 byte slices.\n\/\/!\n\/\/! Additionally, on Unix [`OsString`] implements the\n\/\/! `std::os::unix::ffi::`[`OsStringExt`][unix.OsStringExt] trait,\n\/\/! which provides [`from_vec`] and [`into_vec`] methods that consume\n\/\/! their arguments, and take or produce vectors of [`u8`].\n\/\/!\n\/\/! ## On Windows\n\/\/!\n\/\/! On Windows, [`OsStr`] implements the\n\/\/! `std::os::windows::ffi::`[`OsStrExt`][windows.OsStrExt] trait,\n\/\/! which provides an [`encode_wide`] method. This provides an\n\/\/! iterator that can be [`collect`]ed into a vector of [`u16`].\n\/\/!\n\/\/! Additionally, on Windows [`OsString`] implements the\n\/\/! `std::os::windows:ffi::`[`OsStringExt`][windows.OsStringExt]\n\/\/! trait, which provides a [`from_wide`] method.

This module provides utilities to handle data across non-Rust\n\/\/! interfaces, like other programming languages and the underlying\n\/\/! operating system. It is mainly of use for FFI (Foreign Function\n\/\/! Interface) bindings and code that needs to exchange C-like strings\n\/\/! with other languages.\n\/\/!\n\/\/! # Overview\n\/\/!\n\/\/! Rust represents owned strings with the [`String`] type, and\n\/\/! borrowed slices of strings with the [`str`] primitive. Both are\n\/\/! always in UTF-8 encoding, and may contain nul bytes in the middle,\n\/\/! i.e. if you look at the bytes that make up the string, there may\n\/\/! be a `\\0` among them. Both `String` and `str` store their length\n\/\/! explicitly; there are no nul terminators at the end of strings\n\/\/! like in C.\n\/\/!\n\/\/! C strings are different from Rust strings:\n\/\/!\n\/\/! * **Encodings** - Rust strings are UTF-8, but C strings may use\n\/\/! other encodings. If you are using a string from C, you should\n\/\/! check its encoding explicitly, rather than just assuming that it\n\/\/! is UTF-8 like you can do in Rust.\n\/\/!\n\/\/! * **Character size** - C strings may use `char` or `wchar_t`-sized\n\/\/! characters; please **note** that C's `char` is different from Rust's.\n\/\/! The C standard leaves the actual sizes of those types open to\n\/\/! interpretation, but defines different APIs for strings made up of\n\/\/! each character type. Rust strings are always UTF-8, so different\n\/\/! Unicode characters will be encoded in a variable number of bytes\n\/\/! each. The Rust type [`char`] represents a '[Unicode scalar\n\/\/! value]', which is similar to, but not the same as, a '[Unicode\n\/\/! code point]'.\n\/\/!\n\/\/! * **Nul terminators and implicit string lengths** - Often, C\n\/\/! strings are nul-terminated, i.e. they have a `\\0` character at the\n\/\/! end. The length of a string buffer is not stored, but has to be\n\/\/! calculated; to compute the length of a string, C code must\n\/\/! manually call a function like `strlen()` for `char`-based strings,\n\/\/! or `wcslen()` for `wchar_t`-based ones. Those functions return\n\/\/! the number of characters in the string excluding the nul\n\/\/! terminator, so the buffer length is really `len+1` characters.\n\/\/! Rust strings don't have a nul terminator; their length is always\n\/\/! stored and does not need to be calculated. While in Rust\n\/\/! accessing a string's length is a O(1) operation (because the\n\/\/! length is stored); in C it is an O(length) operation because the\n\/\/! length needs to be computed by scanning the string for the nul\n\/\/! terminator.\n\/\/!\n\/\/! * **Internal nul characters** - When C strings have a nul\n\/\/! terminator character, this usually means that they cannot have nul\n\/\/! characters in the middle — a nul character would essentially\n\/\/! truncate the string. Rust strings *can* have nul characters in\n\/\/! the middle, because nul does not have to mark the end of the\n\/\/! string in Rust.\n\/\/!\n\/\/! # Representations of non-Rust strings\n\/\/!\n\/\/! [`CString`] and [`CStr`] are useful when you need to transfer\n\/\/! UTF-8 strings to and from languages with a C ABI, like Python.\n\/\/!\n\/\/! * **From Rust to C:** [`CString`] represents an owned, C-friendly\n\/\/! string: it is nul-terminated, and has no internal nul characters.\n\/\/! Rust code can create a [`CString`] out of a normal string (provided\n\/\/! that the string doesn't have nul characters in the middle), and\n\/\/! then use a variety of methods to obtain a raw `*mut `[`u8`] that can\n\/\/! then be passed as an argument to functions which use the C\n\/\/! conventions for strings.\n\/\/!\n\/\/! * **From C to Rust:** [`CStr`] represents a borrowed C string; it\n\/\/! is what you would use to wrap a raw `*const `[`u8`] that you got from\n\/\/! a C function. A [`CStr`] is guaranteed to be a nul-terminated array\n\/\/! of bytes. Once you have a [`CStr`], you can convert it to a Rust\n\/\/! [`&str`][`str`] if it's valid UTF-8, or lossily convert it by adding\n\/\/! replacement characters.\n\/\/!\n\/\/!

The following operator traits are implemented for the generated `struct`:\n\/\/!\n\/\/! - `BitOr`: union\n\/\/! - `BitAnd`: intersection\n\/\/! - `Sub`: set difference\n\/\/!\n\/\/! # Methods\n\/\/!\n\/\/!

flags common to both `self` and `other`\n\/\/\/ - `contains`: `true` all of the flags in `other` are contained within `self`\n\/\/\/ - `insert`: inserts the specified flags in-place\n\/\/\/ - `remove`: removes the specified flags in-place\n\/\/\/ - `toggle`: the specified flags will be inserted if not present, and removed\n\/\/\/             if they are.\n#[macro_export]\nmacro_rules!

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\n#![crate_name = \"rustc_typeck\"]\n#![unstable(feature = \"rustc_private\")]\n#![staged_api]\n#![crate_type = \"dylib\"]\n#![crate_type = \"rlib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n      html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n      html_root_url = \"http:\/\/doc.rust-lang.org\/nightly\/\")]\n\n#![allow(non_camel_case_types)]\n\n#![feature(box_syntax)]\n#![feature(collections)]\n#![feature(core)]\n#![feature(int_uint)]\n#![feature(quote)]\n#![feature(rustc_diagnostic_macros)]\n#![feature(rustc_private)]\n#![feature(slicing_syntax, unsafe_destructor)]\n#![feature(staged_api)]\n#![feature(std_misc)]\n\n#[macro_use] extern crate log;\n#[macro_use] extern crate syntax;\n\nextern crate arena;\nextern crate fmt_macros;\nextern crate rustc;\n\npub use rustc::lint;\npub use rustc::metadata;\npub use rustc::middle;\npub use rustc::session;\npub use rustc::util;\n\nuse middle::def;\nuse middle::infer;\nuse middle::subst;\nuse middle::subst::VecPerParamSpace;\nuse middle::ty::{self, Ty};\nuse session::config;\nuse util::common::time;\nuse util::ppaux::Repr;\nuse util::ppaux;\n\nuse syntax::codemap::Span;\nuse syntax::print::pprust::*;\nuse syntax::{ast, ast_map, abi};\nuse syntax::ast_util::local_def;\n\nuse std::cell::RefCell;\n\n\/\/ NB: This module needs to be declared first so diagnostics are\n\/\/ registered before they are used.\npub mod diagnostics;\n\nmod check;\nmod rscope;\nmod astconv;\nmod collect;\nmod coherence;\nmod variance;\n\nstruct TypeAndSubsts<'tcx> {\n    pub substs: subst::Substs<'tcx>,\n    pub ty: Ty<'tcx>,\n}\n\nstruct CrateCtxt<'a, 'tcx: 'a> {\n    \/\/ A mapping from method call sites to traits that have that method.\n    trait_map: ty::TraitMap,\n    \/\/\/ A vector of every trait accessible in the whole crate\n    \/\/\/ (i.e. including those from subcrates).

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\n#![crate_name = \"rustc_typeck\"]\n#![unstable(feature = \"rustc_private\")]\n#![staged_api]\n#![crate_type = \"dylib\"]\n#![crate_type = \"rlib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n      html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n      html_root_url = \"http:\/\/doc.rust-lang.org\/nightly\/\")]\n\n#![allow(non_camel_case_types)]\n\n#![feature(box_syntax)]\n#![feature(collections)]\n#![feature(core)]\n#![feature(int_uint)]\n#![feature(quote)]\n#![feature(rustc_diagnostic_macros)]\n#![feature(rustc_private)]\n#![feature(slicing_syntax, unsafe_destructor)]\n#![feature(staged_api)]\n\n#[macro_use] extern crate log;\n#[macro_use] extern crate syntax;\n\nextern crate arena;\nextern crate fmt_macros;\nextern crate rustc;\n\npub use rustc::lint;\npub use rustc::metadata;\npub use rustc::middle;\npub use rustc::session;\npub use rustc::util;\n\nuse middle::def;\nuse middle::infer;\nuse middle::subst;\nuse middle::subst::VecPerParamSpace;\nuse middle::ty::{self, Ty};\nuse session::config;\nuse util::common::time;\nuse util::ppaux::Repr;\nuse util::ppaux;\n\nuse syntax::codemap::Span;\nuse syntax::print::pprust::*;\nuse syntax::{ast, ast_map, abi};\nuse syntax::ast_util::local_def;\n\nuse std::cell::RefCell;\n\n\/\/ NB: This module needs to be declared first so diagnostics are\n\/\/ registered before they are used.\npub mod diagnostics;\n\nmod check;\nmod rscope;\nmod astconv;\nmod collect;\nmod coherence;\nmod variance;\n\nstruct TypeAndSubsts<'tcx> {\n    pub substs: subst::Substs<'tcx>,\n    pub ty: Ty<'tcx>,\n}\n\nstruct CrateCtxt<'a, 'tcx: 'a> {\n    \/\/ A mapping from method call sites to traits that have that method.\n    trait_map: ty::TraitMap,\n    \/\/\/ A vector of every trait accessible in the whole crate\n    \/\/\/ (i.e. including those from subcrates).

The `Default` trait for types which may have meaningful default values.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/\/ A trait for giving a type a useful default value.\n\/\/\/\n\/\/\/ Sometimes, you want to fall back to some kind of default value, and\n\/\/\/ don't particularly care what it is. This comes up often with `struct`s\n\/\/\/ that define a set of options:\n\/\/\/\n\/\/\/ ```\n\/\/\/ # #[allow(dead_code)]\n\/\/\/ struct SomeOptions {\n\/\/\/     foo: i32,\n\/\/\/     bar: f32,\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ How can we define some default values?

The `Default` trait for types which may have meaningful default values.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/\/ A trait for giving a type a useful default value.\n\/\/\/\n\/\/\/ Sometimes, you want to fall back to some kind of default value, and\n\/\/\/ don't particularly care what it is. This comes up often with `struct`s\n\/\/\/ that define a set of options:\n\/\/\/\n\/\/\/ ```\n\/\/\/ # #[allow(dead_code)]\n\/\/\/ struct SomeOptions {\n\/\/\/     foo: i32,\n\/\/\/     bar: f32,\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ How can we define some default values?

See the `IndexBuffer` documentation for a detailed\n\/\/\/ description.\n\/\/\/\n\/\/\/ The `start` and `end` fields say where in the index-buffer to start and stop reading.\n\/\/\/ Setting `start` to 0, and `end` to the length of the index-buffer, will cause the entire\n\/\/\/ index-buffer to be processed. The `base_vertex` dictates the index of the first vertex\n\/\/\/ in the `VertexBuffer`. This essentially moves the the start of the `VertexBuffer`, to the\n\/\/\/ vertex with this index.\n\/\/\/\n\/\/\/ # Constuction & Handling\n\/\/\/ The `Slice` structure can be constructed automatically when using a `Factory` to create a\n\/\/\/ vertex buffer. If needed, it can also be created manually.\n\/\/\/\n\/\/\/ A `Slice` is required to process a PSO, as it contains the needed information on in what order\n\/\/\/ to draw which vertices. As such, every `draw` call on an `Encoder` requires a `Slice`.\n#[derive(Clone, Debug, Eq, Hash, PartialEq)]\npub struct Slice<R: Resources> {\n    \/\/\/ The start index of the index-buffer.

For example, for architectures with\n\/\/ callee\/caller saved registers, the context will only reflect the callee-saved\n\/\/ registers. This is because the caller saved registers are already stored\n\/\/ elsewhere on the stack (if it was necessary anyway).\n\/\/\n\/\/ Additionally, there may be fields on various architectures which are unused\n\/\/ entirely because they only reflect what is theoretically possible for a\n\/\/ \"complete register set\" to show, but user-space cannot alter these registers.\n\/\/ An example of this would be the segment selectors for x86.\n\/\/\n\/\/ These structures\/functions are roughly in-sync with the source files inside\n\/\/ of src\/rt\/arch\/$arch.

{"text":"<commit_before><commit_msg>Revert \"docs(examples): De-duplicate subcommand examples\"<commit_after>\/\/ Working with subcommands is simple. There are a few key points to remember when working with\n\/\/ subcommands in clap. First, Subcommands are really just Apps. This means they can have their own\n\/\/ settings, version, authors, args, and even their own subcommands. The next thing to remember is\n\/\/ that subcommands are set up in a tree like hierarchy.\n\/\/\n\/\/ An ASCII art depiction may help explain this better. Using a fictional version of git as the demo\n\/\/ subject. Imagine the following are all subcommands of git (note, the author is aware these aren't\n\/\/ actually all subcommands in the real git interface, but it makes explanation easier)\n\/\/\n\/\/            Top Level App (git)                         TOP\n\/\/                           |\n\/\/    -----------------------------------------\n\/\/   \/             |                \\          \\\n\/\/ clone          push              add       commit      LEVEL 1\n\/\/   |           \/    \\            \/    \\       |\n\/\/  url      origin   remote    ref    name   message     LEVEL 2\n\/\/           \/                  \/\\\n\/\/        path            remote  local                   LEVEL 3\n\/\/\n\/\/ Given the above fictional subcommand hierarchy, valid runtime uses would be (not an all inclusive\n\/\/ list):\n\/\/\n\/\/ $ git clone url\n\/\/ $ git push origin path\n\/\/ $ git add ref local\n\/\/ $ git commit message\n\/\/\n\/\/ Notice only one command per \"level\" may be used. You could not, for example, do:\n\/\/\n\/\/ $ git clone url push origin path\n\/\/\n\/\/ It's also important to know that subcommands each have their own set of matches and may have args\n\/\/ with the same name as other subcommands in a different part of the tree hierarchy (i.e. the arg\n\/\/ names aren't in a flat namespace).\n\/\/\n\/\/ In order to use subcommands in clap, you only need to know which subcommand you're at in your\n\/\/ tree, and which args are defined on that subcommand.\n\/\/\n\/\/ Let's make a quick program to illustrate.

An instance of `Future`\n\/\/! is handed back to represent that the work may be done later, and futher\n\/\/! computations can be chained along with it as well.\n\/\/!\n\/\/! ```rust\n\/\/! extern crate futures;\n\/\/! extern crate futures_cpupool;\n\/\/!\n\/\/! use std::sync::mpsc::channel;\n\/\/!\n\/\/! use futures::Future;\n\/\/! use futures_cpupool::CpuPool;\n\/\/!\n\/\/! # fn long_running_computation() -> u32 { 2 }\n\/\/! # fn long_running_computation2(a: u32) -> u32 { a }\n\/\/! # fn main() {\n\/\/!\n\/\/! \/\/ Create a worker thread pool with four threads\n\/\/! let pool = CpuPool::new(4);\n\/\/!\n\/\/! \/\/ Execute some work on the thread pool, optionally closing over data.\n\/\/! let a = pool.execute(long_running_computation);\n\/\/! let b = pool.execute(|| long_running_computation2(100));\n\/\/!\n\/\/! \/\/ Express some further computation once the work is completed on the thread\n\/\/! \/\/ pool.\n\/\/! let c = a.join(b).map(|(a, b)| a + b);\n\/\/!\n\/\/! \/\/ Block the current thread to get the result.\n\/\/! let (tx, rx) = channel();\n\/\/! c.then(move |res| {\n\/\/!     tx.send(res)\n\/\/! }).forget();\n\/\/! let res = rx.recv().unwrap();\n\/\/!\n\/\/! \/\/ Print out the result\n\/\/! println!(\"{:?}\", res);\n\/\/! # }\n\/\/! ```\n\n#![deny(missing_docs)]\n\nextern crate crossbeam;\nextern crate futures;\nextern crate num_cpus;\n\nuse std::any::Any;\nuse std::panic::{self, AssertUnwindSafe};\nuse std::sync::Arc;\nuse std::sync::atomic::{AtomicUsize, Ordering};\nuse std::thread;\n\nuse crossbeam::sync::MsQueue;\nuse futures::{Future, oneshot, Oneshot, Poll};\n\n\/\/\/ A thread pool intended to run CPU intensive work.\n\/\/\/\n\/\/\/ This thread pool will hand out futures representing the completed work\n\/\/\/ that happens on the thread pool itself, and the futures can then be later\n\/\/\/ composed with other work as part of an overall computation.\n\/\/\/\n\/\/\/ The worker threads associated with a thread pool are kept alive so long as\n\/\/\/ there is an open handle to the `CpuPool` or there is work running on them.

On OSes which support timerfd_create, we can use these much more accurate\n\/\/! timers over select() + a timeout (see timer_other.rs). This strategy still\n\/\/! employs a worker thread which does the waiting on the timer fds (to send\n\/\/! messages away).\n\/\/!\n\/\/! The worker thread in this implementation uses epoll(7) to block. It\n\/\/! maintains a working set of *all* native timers in the process, along with a\n\/\/! pipe file descriptor used to communicate that there is data available on the\n\/\/! incoming channel to the worker thread. Timers send requests to update their\n\/\/! timerfd settings to the worker thread (see the comment above 'oneshot' for\n\/\/! why).\n\/\/!\n\/\/! As with timer_other, timers just using sleep() do not use the timerfd at\n\/\/! all. They remove the timerfd from the worker thread and then invoke usleep()\n\/\/! to block the calling thread.\n\/\/!\n\/\/! As with timer_other, all units in this file are in units of millseconds.\n\nuse std::comm::Data;\nuse std::libc;\nuse std::ptr;\nuse std::os;\nuse std::rt::rtio;\nuse std::hashmap::HashMap;\nuse std::unstable::intrinsics;\n\nuse io::file::FileDesc;\nuse io::IoResult;\nuse io::timer_helper;\n\npub struct Timer {\n    priv fd: FileDesc,\n    priv on_worker: bool,\n}\n\npub enum Req {\n    NewTimer(libc::c_int, Chan<()>, bool, imp::itimerspec),\n    RemoveTimer(libc::c_int, Chan<()>),\n    Shutdown,\n}\n\nfn helper(input: libc::c_int, messages: Port<Req>) {\n    let efd = unsafe { imp::epoll_create(10) };\n    let _fd1 = FileDesc::new(input, true);\n    let _fd2 = FileDesc::new(efd, true);\n\n    fn add(efd: libc::c_int, fd: libc::c_int) {\n        let event = imp::epoll_event {\n            events: imp::EPOLLIN as u32,\n            data: imp::epoll_data_t { fd: fd, pad: 0, }\n        };\n        let ret = unsafe {\n            imp::epoll_ctl(efd, imp::EPOLL_CTL_ADD, fd, &event)\n        };\n        assert_eq!(ret, 0);\n    }\n    fn del(efd: libc::c_int, fd: libc::c_int) {\n        let event = imp::epoll_event {\n            events: 0, data: imp::epoll_data_t { fd: 0, pad: 0, }\n        };\n        let ret = unsafe {\n            imp::epoll_ctl(efd, imp::EPOLL_CTL_DEL, fd, &event)\n        };\n        assert_eq!(ret, 0);\n    }\n\n    add(efd, input);\n    let events: [imp::epoll_event, ..16] = unsafe { intrinsics::init() };\n    let mut map: HashMap<libc::c_int, (Chan<()>, bool)> = HashMap::new();\n    'outer: loop {\n        let n = match unsafe {\n            imp::epoll_wait(efd, events.as_ptr(),\n                            events.len() as libc::c_int, -1)\n        } {\n            0 => fail!(\"epoll_wait returned immediately!\"),\n            -1 if os::errno() == libc::EINTR as int => { continue }\n            -1 => fail!(\"epoll wait failed: {}\", os::last_os_error()),\n            n => n\n        };\n\n        let mut incoming = false;\n        debug!(\"{} events to process\", n);\n        for event in events.slice_to(n as uint).iter() {\n            let fd = event.data.fd;\n            debug!(\"data on fd {} (input = {})\", fd, input);\n            if fd == input {\n                let mut buf = [0, ..1];\n                \/\/ drain the input file descriptor of its input\n                FileDesc::new(fd, false).inner_read(buf).unwrap();\n                incoming = true;\n            } else {\n                let mut bits = [0, ..8];\n                \/\/ drain the timerfd of how many times its fired\n                \/\/\n                \/\/ FIXME: should this perform a send() this number of\n                \/\/      times?\n                FileDesc::new(fd, false).inner_read(bits).unwrap();\n                let remove = {\n                    match map.find(&fd).expect(\"fd unregistered\") {\n                        &(ref c, oneshot) => !c.try_send(()) || oneshot\n                    }\n                };\n                if remove {\n                    map.remove(&fd);\n                    del(efd, fd);\n                }\n            }\n        }\n\n        while incoming {\n            match messages.try_recv() {\n                Data(NewTimer(fd, chan, one, timeval)) => {\n                    \/\/ acknowledge we have the new channel, we will never send\n                    \/\/ another message to the old channel\n                    chan.send(());\n\n                    \/\/ If we haven't previously seen the file descriptor, then\n                    \/\/ we need to add it to the epoll set.\n                    if map.insert(fd, (chan, one)) {\n                        add(efd, fd);\n                    }\n\n                    \/\/ Update the timerfd's time value now that we have control\n                    \/\/ of the timerfd\n                    let ret = unsafe {\n                        imp::timerfd_settime(fd, 0, &timeval, ptr::null())\n                    };\n                    assert_eq!(ret, 0);\n                }\n\n                Data(RemoveTimer(fd, chan)) => {\n                    if map.remove(&fd) {\n                        del(efd, fd);\n                    }\n                    chan.send(());\n                }\n\n                Data(Shutdown) => {\n                    assert!(map.len() == 0);\n                    break 'outer;\n                }\n\n                _ => break,\n            }\n        }\n    }\n}\n\nimpl Timer {\n    pub fn new() -> IoResult<Timer> {\n        timer_helper::boot(helper);\n        match unsafe { imp::timerfd_create(imp::CLOCK_MONOTONIC, 0) } {\n            -1 => Err(super::last_error()),\n            n => Ok(Timer { fd: FileDesc::new(n, true), on_worker: false, }),\n        }\n    }\n\n    pub fn sleep(ms: u64) {\n        unsafe { libc::usleep((ms * 1000) as libc::c_uint);

On OSes which support timerfd_create, we can use these much more accurate\n\/\/! timers over select() + a timeout (see timer_other.rs). This strategy still\n\/\/! employs a worker thread which does the waiting on the timer fds (to send\n\/\/! messages away).\n\/\/!\n\/\/! The worker thread in this implementation uses epoll(7) to block. It\n\/\/! maintains a working set of *all* native timers in the process, along with a\n\/\/! pipe file descriptor used to communicate that there is data available on the\n\/\/! incoming channel to the worker thread. Timers send requests to update their\n\/\/! timerfd settings to the worker thread (see the comment above 'oneshot' for\n\/\/! why).\n\/\/!\n\/\/! As with timer_other, timers just using sleep() do not use the timerfd at\n\/\/! all. They remove the timerfd from the worker thread and then invoke usleep()\n\/\/! to block the calling thread.\n\/\/!\n\/\/! As with timer_other, all units in this file are in units of millseconds.\n\nuse std::comm::Data;\nuse std::libc;\nuse std::ptr;\nuse std::os;\nuse std::rt::rtio;\nuse std::hashmap::HashMap;\nuse std::unstable::intrinsics;\n\nuse io::file::FileDesc;\nuse io::IoResult;\nuse io::timer_helper;\n\npub struct Timer {\n    priv fd: FileDesc,\n    priv on_worker: bool,\n}\n\npub enum Req {\n    NewTimer(libc::c_int, Chan<()>, bool, imp::itimerspec),\n    RemoveTimer(libc::c_int, Chan<()>),\n    Shutdown,\n}\n\nfn helper(input: libc::c_int, messages: Port<Req>) {\n    let efd = unsafe { imp::epoll_create(10) };\n    let _fd1 = FileDesc::new(input, true);\n    let _fd2 = FileDesc::new(efd, true);\n\n    fn add(efd: libc::c_int, fd: libc::c_int) {\n        let event = imp::epoll_event {\n            events: imp::EPOLLIN as u32,\n            data: fd as i64,\n        };\n        let ret = unsafe {\n            imp::epoll_ctl(efd, imp::EPOLL_CTL_ADD, fd, &event)\n        };\n        assert_eq!(ret, 0);\n    }\n    fn del(efd: libc::c_int, fd: libc::c_int) {\n        let event = imp::epoll_event { events: 0, data: 0 };\n        let ret = unsafe {\n            imp::epoll_ctl(efd, imp::EPOLL_CTL_DEL, fd, &event)\n        };\n        assert_eq!(ret, 0);\n    }\n\n    add(efd, input);\n    let events: [imp::epoll_event, ..16] = unsafe { intrinsics::init() };\n    let mut map: HashMap<libc::c_int, (Chan<()>, bool)> = HashMap::new();\n    'outer: loop {\n        let n = match unsafe {\n            imp::epoll_wait(efd, events.as_ptr(),\n                            events.len() as libc::c_int, -1)\n        } {\n            0 => fail!(\"epoll_wait returned immediately!\"),\n            -1 if os::errno() == libc::EINTR as int => { continue }\n            -1 => fail!(\"epoll wait failed: {}\", os::last_os_error()),\n            n => n\n        };\n\n        let mut incoming = false;\n        debug!(\"{} events to process\", n);\n        for event in events.slice_to(n as uint).iter() {\n            let fd = event.data as libc::c_int;\n            debug!(\"data on fd {} (input = {})\", fd, input);\n            if fd == input {\n                let mut buf = [0, ..1];\n                \/\/ drain the input file descriptor of its input\n                FileDesc::new(fd, false).inner_read(buf).unwrap();\n                incoming = true;\n            } else {\n                let mut bits = [0, ..8];\n                \/\/ drain the timerfd of how many times its fired\n                \/\/\n                \/\/ FIXME: should this perform a send() this number of\n                \/\/      times?\n                FileDesc::new(fd, false).inner_read(bits).unwrap();\n                let remove = {\n                    match map.find(&fd).expect(\"fd unregistered\") {\n                        &(ref c, oneshot) => !c.try_send(()) || oneshot\n                    }\n                };\n                if remove {\n                    map.remove(&fd);\n                    del(efd, fd);\n                }\n            }\n        }\n\n        while incoming {\n            match messages.try_recv() {\n                Data(NewTimer(fd, chan, one, timeval)) => {\n                    \/\/ acknowledge we have the new channel, we will never send\n                    \/\/ another message to the old channel\n                    chan.send(());\n\n                    \/\/ If we haven't previously seen the file descriptor, then\n                    \/\/ we need to add it to the epoll set.\n                    if map.insert(fd, (chan, one)) {\n                        add(efd, fd);\n                    }\n\n                    \/\/ Update the timerfd's time value now that we have control\n                    \/\/ of the timerfd\n                    let ret = unsafe {\n                        imp::timerfd_settime(fd, 0, &timeval, ptr::null())\n                    };\n                    assert_eq!(ret, 0);\n                }\n\n                Data(RemoveTimer(fd, chan)) => {\n                    if map.remove(&fd) {\n                        del(efd, fd);\n                    }\n                    chan.send(());\n                }\n\n                Data(Shutdown) => {\n                    assert!(map.len() == 0);\n                    break 'outer;\n                }\n\n                _ => break,\n            }\n        }\n    }\n}\n\nimpl Timer {\n    pub fn new() -> IoResult<Timer> {\n        timer_helper::boot(helper);\n        match unsafe { imp::timerfd_create(imp::CLOCK_MONOTONIC, 0) } {\n            -1 => Err(super::last_error()),\n            n => Ok(Timer { fd: FileDesc::new(n, true), on_worker: false, }),\n        }\n    }\n\n    pub fn sleep(ms: u64) {\n        unsafe { libc::usleep((ms * 1000) as libc::c_uint);

{"text":"<commit_before><commit_msg>examples: pdate tinydb example (#1288)<commit_after>\/\/! A \"tiny database\" and accompanying protocol\n\/\/!\n\/\/! This example shows the usage of shared state amongst all connected clients,\n\/\/! namely a database of key\/value pairs. Each connected client can send a\n\/\/! series of GET\/SET commands to query the current value of a key or set the\n\/\/! value of a key.\n\/\/!\n\/\/! This example has a simple protocol you can use to interact with the server.\n\/\/! To run, first run this in one terminal window:\n\/\/!\n\/\/!     cargo run --example tinydb\n\/\/!\n\/\/! and next in another windows run:\n\/\/!\n\/\/!     cargo run --example connect 127.0.0.1:8080\n\/\/!\n\/\/! In the `connect` window you can type in commands where when you hit enter\n\/\/! you'll get a response from the server for that command. An example session\n\/\/! is:\n\/\/!\n\/\/!\n\/\/!     $ cargo run --example connect 127.0.0.1:8080\n\/\/!     GET foo\n\/\/!     foo = bar\n\/\/!     GET FOOBAR\n\/\/!     error: no key FOOBAR\n\/\/!     SET FOOBAR my awesome string\n\/\/!     set FOOBAR = `my awesome string`, previous: None\n\/\/!     SET foo tokio\n\/\/!     set foo = `tokio`, previous: Some(\"bar\")\n\/\/!     GET foo\n\/\/!     foo = tokio\n\/\/!\n\/\/! Namely you can issue two forms of commands:\n\/\/!\n\/\/! * `GET $key` - this will fetch the value of `$key` from the database and\n\/\/!   return it. The server's database is initially populated with the key `foo`\n\/\/!   set to the value `bar`\n\/\/! * `SET $key $value` - this will set the value of `$key` to `$value`,\n\/\/!   returning the previous value, if any.\n\n#![feature(async_await)]\n#![deny(warnings, rust_2018_idioms)]\n\nuse std::collections::HashMap;\nuse std::env;\nuse std::error::Error;\nuse std::net::SocketAddr;\nuse std::sync::{Arc, Mutex};\n\nuse tokio;\nuse tokio::codec::{Framed, LinesCodec};\nuse tokio::net::TcpListener;\n\nuse futures::{SinkExt, StreamExt};\n\n\/\/\/ The in-memory database shared amongst all clients.\n\/\/\/\n\/\/\/ This database will be shared via `Arc`, so to mutate the internal map we're\n\/\/\/ going to use a `Mutex` for interior mutability.\nstruct Database {\n    map: Mutex<HashMap<String, String>>,\n}\n\n\/\/\/ Possible requests our clients can send us\nenum Request {\n    Get { key: String },\n    Set { key: String, value: String },\n}\n\n\/\/\/ Responses to the `Request` commands above\nenum Response {\n    Value {\n        key: String,\n        value: String,\n    },\n    Set {\n        key: String,\n        value: String,\n        previous: Option<String>,\n    },\n    Error {\n        msg: String,\n    },\n}\n\n#[tokio::main]\nasync fn main() -> Result<(), Box<dyn Error + Send + Sync>> {\n    \/\/ Parse the address we're going to run this server on\n    \/\/ and set up our TCP listener to accept connections.\n    let addr = env::args().nth(1).unwrap_or(\"127.0.0.1:8080\".to_string());\n    let addr = addr.parse::<SocketAddr>()?;\n    let mut listener = TcpListener::bind(&addr)?;\n    println!(\"Listening on: {}\", addr);\n\n    \/\/ Create the shared state of this server that will be shared amongst all\n    \/\/ clients.

This module implements the `Any` trait, which enables dynamic typing\n\/\/! of any `'static` type through runtime reflection.\n\/\/!\n\/\/! `Any` itself can be used to get a `TypeId`, and has more features when used\n\/\/! as a trait object. As `&Any` (a borrowed trait object), it has the `is` and\n\/\/! `downcast_ref` methods, to test if the contained value is of a given type,\n\/\/! and to get a reference to the inner value as a type. As `&mut Any`, there\n\/\/! is also the `downcast_mut` method, for getting a mutable reference to the\n\/\/! inner value. `Box<Any>` adds the `downcast` method, which attempts to\n\/\/! convert to a `Box<T>`. See the [`Box`] documentation for the full details.\n\/\/!\n\/\/!

This module implements the `Any` trait, which enables dynamic typing\n\/\/! of any `'static` type through runtime reflection.\n\/\/!\n\/\/! `Any` itself can be used to get a `TypeId`, and has more features when used\n\/\/! as a trait object. As `&Any` (a borrowed trait object), it has the `is` and\n\/\/! `downcast_ref` methods, to test if the contained value is of a given type,\n\/\/! and to get a reference to the inner value as a type. As `&mut Any`, there\n\/\/! is also the `downcast_mut` method, for getting a mutable reference to the\n\/\/! inner value. `Box<Any>` adds the `downcast` method, which attempts to\n\/\/! convert to a `Box<T>`. See the [`Box`] documentation for the full details.\n\/\/!\n\/\/! Note that &Any is limited to testing whether a value is of a specified\n\/\/! concrete type, and cannot be used to test whether a type implements a trait.\n\/\/!\n\/\/! [`Box`]: ..\/..\/std\/boxed\/struct.Box.html\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! Consider a situation where we want to log out a value passed to a function.\n\/\/! We know the value we're working on implements Debug, but we don't know its\n\/\/! concrete type.  We want to give special treatment to certain types: in this\n\/\/! case printing out the length of String values prior to their value.\n\/\/! We don't know the concrete type of our value at compile time, so we need to\n\/\/! use runtime reflection instead.\n\/\/!\n\/\/! ```rust\n\/\/! use std::fmt::Debug;\n\/\/! use std::any::Any;\n\/\/!\n\/\/! \/\/ Logger function for any type that implements Debug.\n\/\/! fn log<T: Any + Debug>(value: &T) {\n\/\/!     let value_any = value as &Any;\n\/\/!\n\/\/!     \/\/ try to convert our value to a String.

The traits in this module provide a general way to talk about conversions\n\/\/! from one type to another. They follow the standard Rust conventions of\n\/\/! `as`\/`into`\/`from`.\n\/\/!\n\/\/! Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Impl the `As*` traits for reference-to-reference conversions\n\/\/! - Impl the `Into` trait when you want to consume the value in the conversion\n\/\/! - The `From` trait is the most flexible, useful for value _and_ reference conversions\n\/\/! - The `TryFrom` and `TryInto` traits behave like `From` and `Into`, but allow for the\n\/\/!   conversion to fail\n\/\/!\n\/\/! As a library author, you should prefer implementing `From<T>` or `TryFrom<T>` rather than\n\/\/! `Into<U>` or `TryInto<U>`, as `From` and `TryFrom` provide greater flexibility and offer\n\/\/! equivalent `Into` or `TryInto` implementations for free, thanks to a blanket implementation\n\/\/! in the standard library.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - `AsRef` and `AsMut` auto-dereference if the inner type is a reference\n\/\/! - `From<U> for T` implies `Into<T> for U`\n\/\/! - `TryFrom<U> for T` implies `TryInto<T> for U`\n\/\/! - `From` and `Into` are reflexive, which means that all types can `into()`\n\/\/!   themselves and `from()` themselves\n\/\/!\n\/\/! See each trait for usage examples.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/\/ A cheap, reference-to-reference conversion.\n\/\/\/\n\/\/\/ `AsRef` is very similar to, but different than, [`Borrow`].

Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Impl the `As*` traits for reference-to-reference conversions\n\/\/! - Impl the [`Into`] trait when you want to consume the value in the conversion\n\/\/! - The [`From`] trait is the most flexible, useful for value _and_ reference conversions\n\/\/! - The [`TryFrom`] and [`TryInto`] traits behave like [`From`] and [`Into`], but allow for the\n\/\/!   conversion to fail\n\/\/!\n\/\/! As a library author, you should prefer implementing [`From<T>`][`From`] or\n\/\/! [`TryFrom<T>`][`TryFrom`] rather than [`Into<U>`][`Into`] or [`TryInto<U>`][`TryInto`],\n\/\/! as [`From`] and [`TryFrom`] provide greater flexibility and offer\n\/\/! equivalent [`Into`] or [`TryInto`] implementations for free, thanks to a blanket implementation\n\/\/! in the standard library.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - [`AsRef`] and [`AsMut`] auto-dereference if the inner type is a reference\n\/\/! - [`From`]`<U> for T` implies [`Into`]`<T> for U`\n\/\/! - [`TryFrom`]`<U> for T` implies [`TryInto`]`<T> for U`\n\/\/! - [`From`] and [`Into`] are reflexive, which means that all types can `into()`\n\/\/!   themselves and `from()` themselves\n\/\/!\n\/\/!

In other\n\/\/\/ words, each tick of the underlying clock may not be the same length (e.g.\n\/\/\/ some seconds may be longer than others). An instant may jump forwards or\n\/\/\/ experience time dilation (slow down or speed up), but it will never go\n\/\/\/ backwards.\n\/\/\/\n\/\/\/ Instants are opaque types that can only be compared to one another.

In other\n\/\/\/ words, each tick of the underlying clock may not be the same length (e.g.\n\/\/\/ some seconds may be longer than others). An instant may jump forwards or\n\/\/\/ experience time dilation (slow down or speed up), but it will never go\n\/\/\/ backwards.\n\/\/\/\n\/\/\/ Instants are opaque types that can only be compared to one another. There is\n\/\/\/ no method to get \"the number of seconds\" from an instant. Instead, it only\n\/\/\/ allows measuring the duration between two instants (or comparing two\n\/\/\/ instants).\n\/\/\/\n\/\/\/ Example:\n\/\/\/\n\/\/\/ ```no_run\n\/\/\/ use std::time::{Duration, Instant};\n\/\/\/ use std::thread::sleep;\n\/\/\/\n\/\/\/ fn main() {\n\/\/\/    let now = Instant::now();\n\/\/\/\n\/\/\/    \/\/ we sleep for 2 seconds\n\/\/\/    sleep(Duration::new(2, 0));\n\/\/\/    \/\/ it prints '2'\n\/\/\/    println!(\"{}\", now.elapsed().as_secs());\n\/\/\/ }\n\/\/\/ ```\n#[derive(Copy, Clone, PartialEq, Eq, PartialOrd, Ord)]\n#[stable(feature = \"time2\", since = \"1.8.0\")]\npub struct Instant(time::Instant);\n\n\/\/\/ A measurement of the system clock, useful for talking to\n\/\/\/ external entities like the file system or other processes.\n\/\/\/\n\/\/\/ Distinct from the `Instant` type, this time measurement **is not\n\/\/\/ monotonic**. This means that you can save a file to the file system, then\n\/\/\/ save another file to the file system, **and the second file has a\n\/\/\/ `SystemTime` measurement earlier than the second**. In other words, an\n\/\/\/ operation that happens after another operation in real time may have an\n\/\/\/ earlier `SystemTime`!\n\/\/\/\n\/\/\/ Consequently, comparing two `SystemTime` instances to learn about the\n\/\/\/ duration between them returns a `Result` instead of an infallible `Duration`\n\/\/\/ to indicate that this sort of time drift may happen and needs to be handled.\n\/\/\/\n\/\/\/ Although a `SystemTime` cannot be directly inspected, the `UNIX_EPOCH`\n\/\/\/ constant is provided in this module as an anchor in time to learn\n\/\/\/ information about a `SystemTime`.

[Handler](handler\/trait.Handler.html).\n\/\/!\n\/\/! # Example\n\/\/!\n\/\/! ```\n\/\/! use mio::{event, EventLoop, IoAcceptor, Handler, Token};\n\/\/! use mio::net::{SockAddr};\n\/\/! use mio::net::tcp::{TcpSocket, TcpAcceptor};\n\/\/!\n\/\/! \/\/ Setup some tokens to allow us to identify which event is\n\/\/! \/\/ for which socket.\n\/\/! const SERVER: Token = Token(0);\n\/\/! const CLIENT: Token = Token(1);\n\/\/!\n\/\/! let addr = SockAddr::parse(\"127.0.0.1:13265\")\n\/\/!     .expect(\"could not parse InetAddr\");\n\/\/!\n\/\/! \/\/ Setup the server socket\n\/\/! let server = TcpSocket::v4().unwrap()\n\/\/!     .bind(&addr).unwrap()\n\/\/!     .listen(256u).unwrap();\n\/\/!\n\/\/! \/\/ Create an event loop\n\/\/! let mut event_loop = EventLoop::<(), ()>::new().unwrap();\n\/\/!\n\/\/! \/\/ Start listening for incoming connections\n\/\/! event_loop.register(&server, SERVER).unwrap();\n\/\/!\n\/\/! \/\/ Setup the client socket\n\/\/! let sock = TcpSocket::v4().unwrap();\n\/\/!\n\/\/! \/\/ Connect to the server\n\/\/! sock.connect(&addr).unwrap();\n\/\/!\n\/\/! \/\/ Register the socket\n\/\/! event_loop.register(&sock, CLIENT).unwrap();\n\/\/!\n\/\/! \/\/ Define a handler to process the events\n\/\/! struct MyHandler(TcpAcceptor);\n\/\/!\n\/\/! impl Handler<(), ()> for MyHandler {\n\/\/!     fn readable(&mut self, event_loop: &mut EventLoop<(), ()>, token: Token, _: event::ReadHint) {\n\/\/!         match token {\n\/\/!

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/! # The Rust core allocation library\n\/\/!\n\/\/! This is the lowest level library through which allocation in Rust can be\n\/\/! performed where the allocation is assumed to succeed. This library will\n\/\/! trigger a task failure when allocation fails.\n\/\/!\n\/\/! This library, like libcore, is not intended for general usage, but rather as\n\/\/! a building block of other libraries. The types and interfaces in this\n\/\/! library are reexported through the [standard library](..\/std\/index.html),\n\/\/! and should not be used through this library.\n\/\/!\n\/\/! Currently, there are four major definitions in this library.\n\/\/!\n\/\/! ## Boxed values\n\/\/!\n\/\/! The [`Box`](boxed\/index.html) type is the core owned pointer type in Rust.\n\/\/! There can only be one owner of a `Box`, and the owner can decide to mutate\n\/\/! the contents, which live on the heap.\n\/\/!\n\/\/! This type can be sent among tasks efficiently as the size of a `Box` value\n\/\/! is the same as that of a pointer. Tree-like data structures are often built\n\/\/! with boxes because each node often has only one owner, the parent.\n\/\/!\n\/\/! ## Reference counted pointers\n\/\/!\n\/\/! The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a task. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](arc\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This types allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/!

This is the lowest level library through which allocation in Rust can be\n\/\/! performed where the allocation is assumed to succeed. This library will\n\/\/! abort the process when allocation fails.\n\/\/!\n\/\/! This library, like libcore, is not intended for general usage, but rather as\n\/\/! a building block of other libraries. The types and interfaces in this\n\/\/! library are reexported through the [standard library](..\/std\/index.html),\n\/\/! and should not be used through this library.\n\/\/!\n\/\/! Currently, there are four major definitions in this library.\n\/\/!\n\/\/! ## Boxed values\n\/\/!\n\/\/! The [`Box`](boxed\/index.html) type is the core owned pointer type in Rust.\n\/\/! There can only be one owner of a `Box`, and the owner can decide to mutate\n\/\/! the contents, which live on the heap.\n\/\/!\n\/\/! This type can be sent among tasks efficiently as the size of a `Box` value\n\/\/! is the same as that of a pointer. Tree-like data structures are often built\n\/\/! with boxes because each node often has only one owner, the parent.\n\/\/!\n\/\/! ## Reference counted pointers\n\/\/!\n\/\/! The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a task. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](arc\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This types allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/! The [`heap`](heap\/index.html) and [`libc_heap`](libc_heap\/index.html)\n\/\/! modules are the unsafe interfaces to the underlying allocation systems. The\n\/\/! `heap` module is considered the default heap, and is not necessarily backed\n\/\/! by libc malloc\/free.  The `libc_heap` module is defined to be wired up to\n\/\/! the system malloc\/free.\n\n#![crate_name = \"alloc\"]\n#![experimental]\n#![license = \"MIT\/ASL2\"]\n#![crate_type = \"rlib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n       html_root_url = \"http:\/\/doc.rust-lang.org\/\")]\n\n#![no_std]\n#![feature(lang_items, phase, unsafe_destructor)]\n\n#[phase(plugin, link)]\nextern crate core;\nextern crate libc;\n\n\/\/ Allow testing this library\n\n#[cfg(test)] extern crate debug;\n#[cfg(test)] extern crate native;\n#[cfg(test)] #[phase(plugin, link)] extern crate std;\n#[cfg(test)] #[phase(plugin, link)] extern crate log;\n\n\/\/ The deprecated name of the boxed module\n\n#[deprecated = \"use boxed instead\"]\n#[cfg(not(test))]\npub use boxed as owned;\n\n\/\/ Heaps provided for low-level allocation strategies\n\npub mod heap;\npub mod libc_heap;\npub mod util;\n\n\/\/ Primitive types using the heaps above\n\n#[cfg(not(test))]\npub mod boxed;\npub mod arc;\npub mod rc;\n\n\/\/\/ Common OOM routine used by liballoc\nfn oom() -> ! {\n    \/\/ FIXME(#14674): This really needs to do something other than just abort\n    \/\/                here, but any printing done must be *guaranteed* to not\n    \/\/                allocate.\n    unsafe { core::intrinsics::abort() }\n}\n\n\/\/ FIXME(#14344): When linking liballoc with libstd, this library will be linked\n\/\/                as an rlib (it only exists as an rlib).

It's most commonly seen when attempting to\nreturn a closure:\n\n```compile_fail\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be\nunsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```compile_fail\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable. For example:\n\n```compile_fail\nfn main() {\n    let x: i32;\n    let y = x; \/\/ error, use of possibly uninitialized variable\n}\n```\n\nTo fix this, ensure that any declared variables are initialized before being\nused. Example:\n\n```\nfn main() {\n    let x: i32 = 0;\n    let y = x; \/\/ ok!\n}\n```\n\"##,\n\nE0382: r##\"\nThis error occurs when an attempt is made to use a variable after its contents\nhave been moved elsewhere. For example:\n\n```compile_fail\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nSince `MyStruct` is a type that is not marked `Copy`, the data gets moved out\nof `x` when we set `y`. This is fundamental to Rust's ownership system: outside\nof workarounds like `Rc`, a value cannot be owned by more than one variable.\n\nIf we own the type, the easiest way to address this problem is to implement\n`Copy` and `Clone` on it, as shown below. This allows `y` to copy the\ninformation in `x`, while leaving the original version owned by `x`.

It's most commonly seen when attempting to\nreturn a closure:\n\n```compile_fail\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be\nunsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```compile_fail\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable. For example:\n\n```compile_fail\nfn main() {\n    let x: i32;\n    let y = x; \/\/ error, use of possibly uninitialized variable\n}\n```\n\nTo fix this, ensure that any declared variables are initialized before being\nused. Example:\n\n```\nfn main() {\n    let x: i32 = 0;\n    let y = x; \/\/ ok!\n}\n```\n\"##,\n\nE0382: r##\"\nThis error occurs when an attempt is made to use a variable after its contents\nhave been moved elsewhere.

This is fundamental to Rust's ownership system: outside\nof workarounds like `Rc`, a value cannot be owned by more than one variable.\n\nIf we own the type, the easiest way to address this problem is to implement\n`Copy` and `Clone` on it, as shown below. This allows `y` to copy the\ninformation in `x`, while leaving the original version owned by `x`. Subsequent\nchanges to `x` will not be reflected when accessing `y`.\n\n```\n#[derive(Copy, Clone)]\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nAlternatively, if we don't control the struct's definition, or mutable shared\nownership is truly required, we can use `Rc` and `RefCell`:\n\n```\nuse std::cell::RefCell;\nuse std::rc::Rc;\n\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = Rc::new(RefCell::new(MyStruct{ s: 5u32 }));\n    let y = x.clone();\n    x.borrow_mut().s = 6;\n    println!(\"{}\", x.borrow().s);\n}\n```\n\nWith this approach, x and y share ownership of the data via the `Rc` (reference\ncount type). `RefCell` essentially performs runtime borrow checking: ensuring\nthat at most one writer or multiple readers can access the data at any one time.\n\nIf you wish to learn more about ownership in Rust, start with the chapter in the\nBook:\n\nhttps:\/\/doc.rust-lang.org\/book\/ownership.html\n\"##,\n\nE0383: r##\"\nThis error occurs when an attempt is made to partially reinitialize a\nstructure that is currently uninitialized.\n\nFor example, this can happen when a drop has taken place:\n\n```compile_fail\nstruct Foo {\n    a: u32,\n}\n\nlet mut x = Foo { a: 1 };\ndrop(x); \/\/ `x` is now uninitialized\nx.a = 2; \/\/ error, partial reinitialization of uninitialized structure `t`\n```\n\nThis error can be fixed by fully reinitializing the structure in question:\n\n```\nstruct Foo {\n    a: u32,\n}\n\nlet mut x = Foo { a: 1 };\ndrop(x);\nx = Foo { a: 2 };\n```\n\"##,\n\nE0384: r##\"\nThis error occurs when an attempt is made to reassign an immutable variable.\nFor example:\n\n```compile_fail\nfn main(){\n    let x = 3;\n    x = 5; \/\/ error, reassignment of immutable variable\n}\n```\n\nBy default, variables in Rust are immutable.

Here the block (`{ return; }`) has the return type `char`,\n\/\/! rather than `()`, but the MIR we naively generate still contains\n\/\/! the `_a = ()` write in the unreachable block \"after\" the return.\n\n\nuse rustc_data_structures::bitvec::BitVector;\nuse rustc_data_structures::indexed_vec::{Idx, IndexVec};\nuse rustc::ty::TyCtxt;\nuse rustc::mir::repr::*;\nuse rustc::mir::transform::{MirPass, MirSource, Pass};\nuse rustc::mir::traversal;\nuse std::fmt;\n\npub struct SimplifyCfg<'a> { label: &'a str }\n\nimpl<'a> SimplifyCfg<'a> {\n    pub fn new(label: &'a str) -> Self {\n        SimplifyCfg { label: label }\n    }\n}\n\nimpl<'l, 'tcx> MirPass<'tcx> for SimplifyCfg<'l> {\n    fn run_pass<'a>(&mut self, _tcx: TyCtxt<'a, 'tcx, 'tcx>, _src: MirSource, mir: &mut Mir<'tcx>) {\n        debug!(\"SimplifyCfg({:?}) - simplifying {:?}\", self.label, mir);\n        CfgSimplifier::new(mir).simplify();\n        remove_dead_blocks(mir);\n\n        \/\/ FIXME: Should probably be moved into some kind of pass manager\n        mir.basic_blocks_mut().raw.shrink_to_fit();\n    }\n}\n\nimpl<'l> Pass for SimplifyCfg<'l> {\n    fn disambiguator<'a>(&'a self) -> Option<Box<fmt::Display+'a>> {\n        Some(Box::new(self.label))\n    }\n\n    \/\/ avoid calling `type_name` - it contains `<'static>`\n    fn name(&self) -> ::std::borrow::Cow<'static, str> { \"SimplifyCfg\".into() }\n}\n\npub struct CfgSimplifier<'a, 'tcx: 'a> {\n    basic_blocks: &'a mut IndexVec<BasicBlock, BasicBlockData<'tcx>>,\n    pred_count: IndexVec<BasicBlock, u32>\n}\n\nimpl<'a, 'tcx: 'a> CfgSimplifier<'a, 'tcx> {\n    fn new(mir: &'a mut Mir<'tcx>) -> Self {\n        let mut pred_count = IndexVec::from_elem(0u32, mir.basic_blocks());\n\n        \/\/ we can't use mir.predecessors() here because that counts\n        \/\/ dead blocks, which we don't want to.\n        pred_count[START_BLOCK] = 1;\n\n        for (_, data) in traversal::preorder(mir) {\n            if let Some(ref term) = data.terminator {\n                for &tgt in term.successors().iter() {\n                    pred_count[tgt] += 1;\n                }\n            }\n        }\n\n        let basic_blocks = mir.basic_blocks_mut();\n\n        CfgSimplifier {\n            basic_blocks: basic_blocks,\n            pred_count: pred_count\n        }\n    }\n\n    fn simplify(mut self) {\n        loop {\n            let mut changed = false;\n\n            for bb in (0..self.basic_blocks.len()).map(BasicBlock::new) {\n                if self.pred_count[bb] == 0 {\n                    continue\n                }\n\n                debug!(\"simplifying {:?}\", bb);\n\n                let mut terminator = self.basic_blocks[bb].terminator.take()\n                    .expect(\"invalid terminator state\");\n\n                for successor in terminator.successors_mut() {\n                    self.collapse_goto_chain(successor, &mut changed);\n                }\n\n                let mut new_stmts = vec![];\n                let mut inner_changed = true;\n                while inner_changed {\n                    inner_changed = false;\n                    inner_changed |= self.simplify_branch(&mut terminator);\n                    inner_changed |= self.merge_successor(&mut new_stmts, &mut terminator);\n                    changed |= inner_changed;\n                }\n\n                self.basic_blocks[bb].statements.extend(new_stmts);\n                self.basic_blocks[bb].terminator = Some(terminator);\n\n                changed |= inner_changed;\n            }\n\n            if !changed { break }\n        }\n    }\n\n    \/\/ Collapse a goto chain starting from `start`\n    fn collapse_goto_chain(&mut self, start: &mut BasicBlock, changed: &mut bool) {\n        let mut terminator = match self.basic_blocks[*start] {\n            BasicBlockData {\n                ref statements,\n                terminator: ref mut terminator @ Some(Terminator {\n                    kind: TerminatorKind::Goto { .. }, ..\n                }), ..\n            } if statements.is_empty() => terminator.take(),\n            \/\/ if `terminator` is None, this means we are in a loop.

This is done with\nthe first parameter to the `draw` function.\n\n## Vertex\n\nThe main trait of this module is `Vertex`, which must be implemented on structs whose instances\ndescribe individual vertices. The trait is unsafe to implement, so you are encouraged to use the\n`implement_vertex!` macro instead:\n\n```\n# #[macro_use]\n# extern crate glium;\n# extern crate glutin;\n# fn main()

texcoords);\n# }\n```\n\n## Vertex buffer\n\nOnce you have a struct that implements the `Vertex` trait, you can build an array of vertices and\nupload it to the video memory by creating a `VertexBuffer`.\n\n```no_run\n# let display: glium::Display = unsafe { ::std::mem::uninitialized() };\n# #[derive(Copy, Clone)]\n# struct MyVertex {\n#     position: [f32; 3],\n#     texcoords: [f32;

 texcoords: [0.0, 0.4]\n    },\n];\n\nlet vertex_buffer = glium::vertex::VertexBuffer::new(&display, data);\n```\n\n## Drawing\n\nWhen you draw, you can pass either a single vertex source or a tuple of multiple sources.\nEach source can be:\n\n - A reference to a `VertexBuffer`.\n - A slice of a vertex buffer, by calling `vertex_buffer.slice(start .. end).unwrap()`.\n - A vertex buffer where each element corresponds to an instance, by\n   caling `vertex_buffer.per_instance()`.\n - The same with a slice, by calling `vertex_buffer.slice(start .. end).unwrap().per_instance()`.\n - A marker indicating a number of vertex sources, with `glium::vertex::EmptyVertexAttributes`.\n - A marker indicating a number of instances, with `glium::vertex::EmptyInstanceAttributes`.\n\n```no_run\n# use

The flag currently\n        \/\/ takes no value as an argument, so the compiler calculates what it\n        \/\/ should pass to the linker as `-rpath`. This unfortunately is based on\n        \/\/ the **compile time** directory structure which when building with\n        \/\/ Cargo will be very different than the runtime directory structure.\n        \/\/\n        \/\/ All that's a really long winded way of saying that if we use\n        \/\/ `-Crpath` then the executables generated have the wrong rpath of\n        \/\/ something like `$ORIGIN\/deps` when in fact the way we distribute\n        \/\/ rustc requires the rpath to be `$ORIGIN\/..\/lib`.\n        \/\/\n        \/\/ So, all in all, to set up the correct rpath we pass the linker\n        \/\/ argument manually via `-C link-args=-Wl,-rpath,...`.

It returns a u32.\n\n# Examples\n\nTo load the extension and use it:\n\n```rust,ignore\n#[phase(syntax)]\nextern mod fourcc;\n\nfn main() {\n    let val = fourcc!(\"\\xC0\\xFF\\xEE!\")\n    \/\/ val is 0xC0FFEE21\n    let big_val = fourcc!(\"foo \", big);\n    \/\/ big_val is 0x21EEFFC0\n}\n ```\n\n# References\n\n* [Wikipedia: FourCC](http:\/\/en.wikipedia.org\/wiki\/FourCC)\n\n*\/\n\n#[crate_id = \"fourcc#0.10-pre\"];\n#[crate_type = \"rlib\"];\n#[crate_type = \"dylib\"];\n#[license = \"MIT\/ASL2\"];\n\n#[feature(macro_registrar, managed_boxes)];\n\nextern mod syntax;\n\nuse syntax::ast;\nuse syntax::ast::Name;\nuse syntax::attr::contains;\nuse syntax::codemap::{Span, mk_sp};\nuse syntax::ext::base;\nuse syntax::ext::base::{SyntaxExtension, BasicMacroExpander, NormalTT, ExtCtxt, MRExpr};\nuse syntax::ext::build::AstBuilder;\nuse syntax::parse;\nuse syntax::parse::token;\nuse syntax::parse::token::InternedString;\n\n#[macro_registrar]\n#[cfg(not(test))]\npub fn macro_registrar(register: |Name, SyntaxExtension|) {\n    register(token::intern(\"fourcc\"),\n        NormalTT(~BasicMacroExpander {\n            expander: expand_syntax_ext,\n            span: None,\n        },\n        None));\n}\n\nuse std::ascii::AsciiCast;\n\npub fn expand_syntax_ext(cx: &mut ExtCtxt, sp: Span, tts: &[ast::TokenTree]) -> base::MacResult {\n    let (expr, endian) = parse_tts(cx, tts);\n\n    let little = match endian {\n        None => target_endian_little(cx, sp),\n        Some(Ident{ident, span}) => match token::get_ident(ident.name).get() {\n            \"little\" => true,\n            \"big\" => false,\n            _ => {\n                cx.span_err(span, \"invalid endian directive in fourcc!\");\n                target_endian_little(cx, sp)\n            }\n        }\n    };\n\n    let s = match expr.node {\n        \/\/ expression is a literal\n        ast::ExprLit(lit) => match lit.node {\n            \/\/ string literal\n            ast::LitStr(ref s, _) => {\n                if !s.get().is_ascii() {\n                    cx.span_err(expr.span, \"non-ascii string literal in fourcc!\");\n                } else if s.get().len() != 4 {\n                    cx.span_err(expr.span, \"string literal with len != 4 in fourcc!\");\n                }\n                s\n            }\n            _ => {\n                cx.span_err(expr.span, \"unsupported literal in fourcc!\");\n                return MRExpr(cx.expr_lit(sp, ast::LitUint(0u64, ast::TyU32)));\n            }\n        },\n        _ => {\n            cx.span_err(expr.span, \"non-literal in fourcc!\");\n            return MRExpr(cx.expr_lit(sp, ast::LitUint(0u64, ast::TyU32)));\n        }\n    };\n\n    let mut val = 0u32;\n    if little {\n        for byte in s.get().bytes_rev().take(4) {\n            val = (val << 8) | (byte as u32);\n        }\n    } else {\n        for byte in s.get().bytes().take(4) {\n            val = (val << 8) | (byte as u32);\n        }\n    }\n    let e = cx.expr_lit(sp, ast::LitUint(val as u64, ast::TyU32));\n    MRExpr(e)\n}\n\nstruct Ident {\n    ident: ast::Ident,\n    span: Span\n}\n\nfn parse_tts(cx: &ExtCtxt, tts: &[ast::TokenTree]) -> (@ast::Expr, Option<Ident>) {\n    let p = &mut parse::new_parser_from_tts(cx.parse_sess(), cx.cfg(), tts.to_owned());\n    let ex = p.parse_expr();\n    let id = if p.token == token::EOF {\n        None\n    } else {\n        p.expect(&token::COMMA);\n        let lo = p.span.lo;\n        let ident = p.parse_ident();\n        let hi = p.last_span.hi;\n        Some(Ident{ident: ident, span: mk_sp(lo, hi)})\n    };\n    if p.token != token::EOF {\n        p.unexpected();\n    }\n    (ex, id)\n}\n\nfn target_endian_little(cx: &ExtCtxt, sp: Span) -> bool {\n    let meta = cx.meta_name_value(sp, InternedString::new(\"target_endian\"),\n        ast::LitStr(InternedString::new(\"little\"), ast::CookedStr));\n    contains(cx.cfg(), meta)\n}\n\n\/\/ Fixes LLVM assert on Windows\n#[test]\nfn dummy_test() { }\n<|endoftext|>"}

{"text":"<commit_before><commit_msg>examples: single-threaded chat combinator example (#794)<commit_after>\/\/! A chat server that broadcasts a message to all connections.\n\/\/!\n\/\/! This is a line-based server which accepts connections, reads lines from\n\/\/! those connections, and broadcasts the lines to all other connected clients.\n\/\/!\n\/\/! This example is similar to chat.rs, but uses combinators and a much more\n\/\/! functional style.\n\/\/!\n\/\/! Because we are here running the reactor\/executor on the same thread instead\n\/\/! of a threadpool, we can avoid full synchronization with Arc + Mutex and use\n\/\/! Rc + RefCell instead. The max performance is however limited to a CPU HW\n\/\/! thread.\n\/\/!\n\/\/! You can test this out by running:\n\/\/!\n\/\/!     cargo run --example chat-combinator-current-thread\n\/\/!\n\/\/! And then in another window run:\n\/\/!\n\/\/!     cargo run --example connect 127.0.0.1:8080\n\/\/!\n\/\/! You can run the second command in multiple windows and then chat between the\n\/\/! two, seeing the messages from the other client as they're received. For all\n\/\/! connected clients they'll all join the same room and see everyone else's\n\/\/! messages.\n\n#![deny(warnings)]\n\nextern crate tokio;\nextern crate futures;\n\nuse tokio::io;\nuse tokio::net::TcpListener;\nuse tokio::prelude::*;\nuse tokio::runtime::current_thread::{Runtime, TaskExecutor};\n\nuse std::collections::HashMap;\nuse std::iter;\nuse std::env;\nuse std::io::{BufReader};\nuse std::rc::Rc;\nuse std::cell::RefCell;\n\n\nfn main() -> Result<(), Box<std::error::Error>> {\n    let mut runtime = Runtime::new().unwrap();\n\n    \/\/ Create the TCP listener we'll accept connections on.\n    let addr = env::args().nth(1).unwrap_or(\"127.0.0.1:8080\".to_string());\n    let addr = addr.parse()?;\n\n    let socket = TcpListener::bind(&addr)?;\n    println!(\"Listening on: {}\", addr);\n\n    \/\/ This is running on the Tokio current_thread runtime, so it will be single-\n    \/\/ threaded.

The traits in this module provide a general way to talk about conversions\n\/\/! from one type to another. They follow the standard Rust conventions of\n\/\/! `as`\/`into`\/`from`.\n\/\/!\n\/\/! Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Use `as` for reference-to-reference conversions\n\/\/! - Use `into` when you want to consume the value\n\/\/! - `from` is the more flexible way, which can convert values and references\n\/\/!\n\/\/! As a library writer, you should prefer implementing `From<T>` rather than\n\/\/! `Into<U>`, as `From` is more flexible (you can't `Into` a reference, where\n\/\/! you can impl `From` for a reference). `From` is also used for generic\n\/\/! implementations.\n\/\/!\n\/\/! **Note:** these traits are for trivial conversion. **They must not fail**. If\n\/\/! they can fail, use a dedicated method which return an `Option<T>` or\n\/\/! a `Result<T, E>`.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - `AsRef` and `AsMut` auto-dereference if the inner type is a reference\n\/\/! - `From<U> for T` implies `Into<T> for U`\n\/\/! - `From` and `Into` are reflexive, which means that all types can `into()`\n\/\/! themselve and `from()` themselve\n\/\/!\n\/\/!

See the LLVM documentation on [[atomics]].\n\n[atomics]: http:\/\/llvm.org\/docs\/Atomics.html\n\nA quick refresher on memory ordering:\n\n* Acquire - a barrier for aquiring a lock. Subsequent reads and writes\n  take place after the barrier.\n* Release - a barrier for releasing a lock. Preceding reads and writes\n  take place before the barrier.\n* Sequentially consistent - sequentially consistent operations are\n  guaranteed to happen in order.

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value.

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested up into inputs and\n* outputs, and subdivides those into declared (input and output) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or output is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase.

The main crate for Iron.\n\/\/!\n\/\/! ## Overview\n\/\/!\n\/\/! Iron is a high level web framework built in and for Rust, built on\n\/\/! [hyper](https:\/\/github.com\/hyperium\/hyper). Iron is designed to take advantage\n\/\/! of Rust's greatest features - its excellent type system and principled\n\/\/! approach to ownership in both single threaded and multi threaded contexts.\n\/\/!\n\/\/! Iron is highly concurrent and can scale horizontally on more machines behind a\n\/\/! load balancer or by running more threads on a more powerful machine. Iron\n\/\/! avoids the bottlenecks encountered in highly concurrent code by avoiding shared\n\/\/! writes and locking in the core framework.\n\/\/!\n\/\/! ## Hello World\n\/\/!\n\/\/! ```no_run\n\/\/! extern crate iron;\n\/\/!\n\/\/! use iron::prelude::*;\n\/\/! use iron::status;\n\/\/!\n\/\/! fn main() {\n\/\/!

Iron is meant to be as extensible and pluggable as possible; Iron's core is\n\/\/! concentrated and avoids unnecessary features by leaving them to middleware,\n\/\/! plugins, and modifiers.\n\/\/!\n\/\/! Middleware, Plugins, and Modifiers are the main ways to extend Iron with new\n\/\/! functionality. Most extensions that would be provided by middleware in other\n\/\/! web frameworks are instead addressed by the much simpler Modifier and Plugin\n\/\/! systems.\n\/\/!\n\/\/! Modifiers allow external code to manipulate Requests and Response in an ergonomic\n\/\/! fashion, allowing third-party extensions to get the same treatment as modifiers\n\/\/! defined in Iron itself. Plugins allow for lazily-evaluated, automatically cached\n\/\/! extensions to Requests and Responses, perfect for parsing, accessing, and\n\/\/! otherwise lazily manipulating an http connection.\n\/\/!\n\/\/! Middleware are only used when it is necessary to modify the control flow of a\n\/\/! Request flow, hijack the entire handling of a Request, check an incoming\n\/\/! Request, or to do final post-processing. This covers areas such as routing,\n\/\/! mounting, static asset serving, final template rendering, authentication, and\n\/\/! logging.\n\/\/!\n\/\/!

The idea is that we have an arbitrary tweet and we want to find tweets\n    \/\/that it replied to, and tweets the user posted that reply to it.\n    \/\/\n    \/\/The first part is fairly easy: it's essentially a linked list, where each node traversal is a\n    \/\/call to tweet::show. Since we're receiving these tweets in reverse-chronological order,\n    \/\/calling push_front makes sure the order of the eventual thread is properly chronological.\n    \/\/\n    \/\/The latter part calls for some creative use of tweet::user_timeline. First we set up the\n    \/\/timeline itself, indicating that replies should be included in the response. Then, rather\n    \/\/than calling start() to get the most recent, we use call() directly, saying \"give me tweets\n    \/\/posted since this ID\". Since this could include tweets that aren't on the same thread, we\n    \/\/need to make keep track of the tweet IDs in the thread, so we can make sure the tweet itself\n    \/\/is a reply to something within the thread. Since the timeline returned by this call is in\n    \/\/reverse-chronologocal order, we rev() the output page to make sure we're pushing tweets in\n    \/\/chronological order. If we wanted to fill our thread buffer completely, we could keep calling\n    \/\/newer() for a certain number of pages or until we've hit our cap, but using the default 20 is\n    \/\/sufficient for this demo.\n\n    \/\/The example post used in this demo is the fourth post in a seven-post thread I\n    \/\/(@QuietMisdreavus) posted shortly before writing this.

Task-local reference-counted boxes (`Rc` type)\n\nThe `Rc` type provides shared ownership of an immutable value. Destruction is deterministic, and\nwill occur as soon as the last owner is gone. It is marked as non-sendable because it avoids the\noverhead of atomic reference counting.\n\nThe `downgrade` method can be used to create a non-owning `Weak` pointer to the box. A `Weak`\npointer can be upgraded to an `Rc` pointer, but will return `None` if the value has already been\nfreed.\n\nFor example, a tree with parent pointers can be represented by putting the nodes behind `Strong`\npointers, and then storing the parent pointers as `Weak` pointers.\n\n*\/\n\nuse core::mem::transmute;\nuse core::cell::Cell;\nuse core::clone::Clone;\nuse core::cmp::{PartialEq, PartialOrd, Eq, Ord, Ordering};\nuse core::kinds::marker;\nuse core::ops::{Deref, Drop};\nuse core::option::{Option, Some, None};\nuse core::ptr;\nuse core::ptr::RawPtr;\nuse core::mem::{min_align_of, size_of};\n\nuse heap::deallocate;\n\nstruct RcBox<T> {\n    value: T,\n    strong: Cell<uint>,\n    weak: Cell<uint>\n}\n\n\/\/\/ Immutable reference counted pointer type\n#[unsafe_no_drop_flag]\npub struct Rc<T> {\n    \/\/ FIXME #12808: strange names to try to avoid interfering with\n    \/\/ field accesses of the contained type via Deref\n    _ptr: *mut RcBox<T>,\n    _nosend: marker::NoSend,\n    _noshare: marker::NoShare\n}\n\nimpl<T> Rc<T> {\n    \/\/\/ Construct a new reference-counted box\n    pub fn new(value: T) -> Rc<T> {\n        unsafe {\n            Rc {\n                \/\/ there is an implicit weak pointer owned by all the\n                \/\/ strong pointers, which ensures that the weak\n                \/\/ destructor never frees the allocation while the\n                \/\/ strong destructor is running, even if the weak\n                \/\/ pointer is stored inside the strong one.\n                _ptr: transmute(box RcBox {\n                    value: value,\n                    strong: Cell::new(1),\n                    weak: Cell::new(1)\n                }),\n                _nosend: marker::NoSend,\n                _noshare: marker::NoShare\n            }\n        }\n    }\n}\n\nimpl<T> Rc<T> {\n    \/\/\/ Downgrade the reference-counted pointer to a weak reference\n    pub fn downgrade(&self) -> Weak<T> {\n        self.inc_weak();\n        Weak {\n            _ptr: self._ptr,\n            _nosend: marker::NoSend,\n            _noshare: marker::NoShare\n        }\n    }\n}\n\nimpl<T: Clone> Rc<T> {\n    \/\/\/ Acquires a mutable pointer to the inner contents by guaranteeing that\n    \/\/\/ the reference count is one (no sharing is possible).\n    \/\/\/\n    \/\/\/ This is also referred to as a copy-on-write operation because the inner\n    \/\/\/ data is cloned if the reference count is greater than one.\n    #[inline]\n    #[experimental]\n    pub fn make_unique<'a>(&'a mut self) -> &'a mut T {\n        \/\/ Note that we hold a strong reference, which also counts as\n        \/\/ a weak reference, so we only clone if there is an\n        \/\/ additional reference of either kind.\n        if self.strong() != 1 || self.weak() != 1 {\n            *self = Rc::new(self.deref().clone())\n        }\n        \/\/ This unsafety is ok because we're guaranteed that the pointer\n        \/\/ returned is the *only* pointer that will ever be returned to T.

For here\n\/\/ stands the bastion of the Turbofish: an impenetrable fortress holding\n\/\/ unshaking against those who would dare suggest the supererogation of the\n\/\/ Turbofish.\n\/\/\n\/\/ Once I was young and foolish and had the impudence to imagine that I could\n\/\/ shake free from the coils by which that creature had us tightly bound. I\n\/\/ dared to suggest that there was a better way: a brighter future, in which\n\/\/ Rustaceans both new and old could be rid of that vile beast. But alas! In\n\/\/ my foolhardiness my ignorance was unveiled and my dreams were dashed\n\/\/ unforgivingly against the rock of syntactic ambiguity.\n\/\/\n\/\/ This humble program, small and insignificant though it might seem,\n\/\/ demonstrates that to which we had previously cast a blind eye: an ambiguity\n\/\/ in permitting generic arguments to be provided without the consent of the\n\/\/ Great Turbofish. Should you be so naïve as to try to revolt against its\n\/\/ mighty clutches, here shall its wrath be indomitably displayed. This\n\/\/ program must pass for all eternity, fundamentally at odds with an impetuous\n\/\/ rebellion against the Turbofish.\n\/\/\n\/\/ My heart aches in sorrow, for I know I am defeated. Let this be a warning\n\/\/ to all those who come after. Here stands the bastion of the Turbofish.\n\nfn main() {\n    let (oh, woe, is, me) = (\"the\", \"Turbofish\", \"remains\", \"undefeated\");\n    let _: (bool, bool) = (oh<woe, is>(me));\n}\n<|endoftext|>"}

Example mime string: `text\/plain;charset=utf-8`\n\/\/!\n\/\/! ```rust\n\/\/! # #[macro_use] extern crate mime;\n\/\/! # fn main() {\n\/\/! let plain_text: mime::Mime = \"text\/plain;charset=utf-8\".parse().unwrap();\n\/\/! assert_eq!(plain_text, mime!(Text\/Plain; Charset=Utf8));\n\/\/! # }\n\/\/! ```\n\n#![doc(html_root_url = \"https:\/\/hyperium.github.io\/mime.rs\")]\n#![cfg_attr(test, deny(warnings))]\n#![cfg_attr(all(features = \"nightly\", test), feature(test))]\n\n#[macro_use]\nextern crate log;\n\n#[cfg(features = \"nightly\")]\n#[cfg(test)]\nextern crate test;\n\nuse std::ascii::AsciiExt;\nuse std::fmt;\nuse std::iter::Enumerate;\nuse std::str::{FromStr, Chars};\n\nmacro_rules! inspect(\n    ($s:expr, $t:expr) => ({\n        let t = $t;\n        trace!(\"inspect {}: {:?}\", $s, t);\n        t\n    })\n);\n\n\/\/\/ Mime, or Media Type. Encapsulates common registers types.\n\/\/\/\n\/\/\/ Consider that a traditional mime type contains a \"top level type\",\n\/\/\/ a \"sub level type\", and 0-N \"parameters\". And they're all strings.\n\/\/\/ Strings everywhere. Strings mean typos. Rust has type safety. We should\n\/\/\/ use types!\n\/\/\/\n\/\/\/ So, Mime bundles together this data into types so the compiler can catch\n\/\/\/ your typos.\n\/\/\/\n\/\/\/ This improves things so you use match without Strings:\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ use mime::{Mime, TopLevel, SubLevel};\n\/\/\/\n\/\/\/ let mime: Mime = \"application\/json\".parse().unwrap();\n\/\/\/\n\/\/\/ match mime {\n\/\/\/     Mime(TopLevel::Application, SubLevel::Json, _) => println!(\"matched json!\"),\n\/\/\/     _ => ()\n\/\/\/ }\n\/\/\/ ```\n#[derive(Clone, Debug)]\npub struct Mime<T: AsRef<[Param]> = Vec<Param>>(pub TopLevel, pub SubLevel, pub T);\n\nimpl<LHS: AsRef<[Param]>, RHS: AsRef<[Param]>> PartialEq<Mime<RHS>> for Mime<LHS> {\n    fn eq(&self, other: &Mime<RHS>) -> bool {\n        self.0 == other.0 && self.1 == other.1 && self.2.as_ref() == other.2.as_ref()\n    }\n}\n\n\/\/\/ Easily create a Mime without having to import so many enums.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ # #[macro_use] extern crate mime;\n\/\/\/\n\/\/\/ # fn main() {\n\/\/\/ let json = mime!(Application\/Json);\n\/\/\/ let plain = mime!(Text\/Plain;

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`marker`](marker\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! for which the [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes the [`ffi`](ffi\/index.html) module for interoperating\n\/\/! with the C language.\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading abstractions.\n\/\/! [`sync`](sync\/index.html) contains further, primitive, shared memory types,\n\/\/! including [`atomic`](sync\/atomic\/index.html), and [`mpsc`](sync\/mpsc\/index.html),\n\/\/! which contains the channel types for message passing.\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the\n\/\/! [`old_io`](old_io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\/\/ Do not remove on snapshot creation.

In general, there may be several ways to \"borrow\" a piece of data.  The\n\/\/! typical ways of borrowing a type `T` are `&T` (a shared borrow) and `&mut T`\n\/\/! (a mutable borrow). But types like `Vec<T>` provide additional kinds of\n\/\/! borrows: the borrowed slices `&[T]` and `&mut [T]`.\n\/\/!\n\/\/! When writing generic code, it is often desirable to abstract over all ways\n\/\/! of borrowing data from a given type. That is the role of the `BorrowFrom`\n\/\/! trait: if `T: BorrowFrom<U>`, then `&T` can be borrowed from `&U`.  A given\n\/\/! type can be borrowed as multiple different types. In particular, `Vec<T>:\n\/\/! BorrowFrom<Vec<T>>` and `[T]: BorrowFrom<Vec<T>>`.\n\/\/!\n\/\/! # The `ToOwned` trait\n\/\/!\n\/\/! Some types make it possible to go from borrowed to owned, usually by\n\/\/! implementing the `Clone` trait. But `Clone` works only for going from `&T`\n\/\/! to `T`. The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/! from any borrow of a given type.\n\/\/!\n\/\/! # The `Cow` (clone-on-write) type\n\/\/!\n\/\/! The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/! can enclose and provide immutable access to borrowed data, and clone the\n\/\/! data lazily when mutation or ownership is required. The type is designed to\n\/\/! work with general borrowed data via the `BorrowFrom` trait.\n\/\/!\n\/\/! `Cow` implements both `Deref`, which means that you can call\n\/\/! non-mutating methods directly on the data it encloses. If mutation\n\/\/! is desired, `to_mut` will obtain a mutable references to an owned\n\/\/! value, cloning if necessary.\n\n#![unstable = \"recently added as part of collections reform\"]\n\nuse clone::Clone;\nuse cmp::{Eq, Ord, Ordering, PartialEq, PartialOrd};\nuse fmt;\nuse kinds::Sized;\nuse ops::Deref;\nuse option::Option;\nuse self::Cow::*;\n\n\/\/\/ A trait for borrowing data.\npub trait BorrowFrom<Sized?

In general, there may be several ways to \"borrow\" a piece of data.  The\n\/\/! typical ways of borrowing a type `T` are `&T` (a shared borrow) and `&mut T`\n\/\/! (a mutable borrow). But types like `Vec<T>` provide additional kinds of\n\/\/! borrows: the borrowed slices `&[T]` and `&mut [T]`.\n\/\/!\n\/\/! When writing generic code, it is often desirable to abstract over all ways\n\/\/! of borrowing data from a given type. That is the role of the `BorrowFrom`\n\/\/! trait: if `T: BorrowFrom<U>`, then `&T` can be borrowed from `&U`.  A given\n\/\/! type can be borrowed as multiple different types. In particular, `Vec<T>:\n\/\/! BorrowFrom<Vec<T>>` and `[T]: BorrowFrom<Vec<T>>`.\n\/\/!\n\/\/! # The `ToOwned` trait\n\/\/!\n\/\/! Some types make it possible to go from borrowed to owned, usually by\n\/\/! implementing the `Clone` trait. But `Clone` works only for going from `&T`\n\/\/! to `T`. The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/! from any borrow of a given type.\n\/\/!\n\/\/! # The `Cow` (clone-on-write) type\n\/\/!\n\/\/! The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/! can enclose and provide immutable access to borrowed data, and clone the\n\/\/! data lazily when mutation or ownership is required. The type is designed to\n\/\/! work with general borrowed data via the `BorrowFrom` trait.\n\/\/!\n\/\/! `Cow` implements both `Deref`, which means that you can call\n\/\/! non-mutating methods directly on the data it encloses. If mutation\n\/\/! is desired, `to_mut` will obtain a mutable references to an owned\n\/\/! value, cloning if necessary.\n\n#![unstable = \"recently added as part of collections reform\"]\n\nuse clone::Clone;\nuse cmp::{Eq, Ord, Ordering, PartialEq, PartialOrd};\nuse fmt;\nuse kinds::Sized;\nuse ops::Deref;\nuse option::Option;\nuse self::Cow::*;\n\n\/\/\/ A trait for borrowing data.\npub trait BorrowFrom<Sized?

This modules contains a set of macros which are exported from the standard\n\/\/! library. Each macro is available for use when linking against the standard\n\/\/! library.\n\n#![unstable(feature = \"std_misc\")]\n\n\/\/\/ The entry point for panic of Rust tasks.\n\/\/\/\n\/\/\/ This macro is used to inject panic into a Rust task, causing the task to\n\/\/\/ unwind and panic entirely. Each task's panic can be reaped as the\n\/\/\/ `Box<Any>` type, and the single-argument form of the `panic!` macro will be\n\/\/\/ the value which is transmitted.\n\/\/\/\n\/\/\/ The multi-argument form of this macro panics with a string and has the\n\/\/\/ `format!` syntax for building a string.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```should_fail\n\/\/\/ # #![allow(unreachable_code)]\n\/\/\/ panic!();\n\/\/\/ panic!(\"this is a terrible mistake!\");\n\/\/\/ panic!(4); \/\/ panic with the value of 4 to be collected elsewhere\n\/\/\/ panic!(\"this is a {} {message}\", \"fancy\", message = \"message\");\n\/\/\/ ```\n#[macro_export]\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\nmacro_rules! panic {\n    () => ({\n        panic!(\"explicit panic\")\n    });\n    ($msg:expr) => ({\n        $crate::rt::begin_unwind($msg, {\n            \/\/ static requires less code at runtime, more constant data\n            static _FILE_LINE: (&'static str, usize) = (file!(), line!() as usize);\n            &_FILE_LINE\n        })\n    });\n    ($fmt:expr, $($arg:tt)+) => ({\n        $crate::rt::begin_unwind_fmt(format_args!($fmt, $($arg)+), {\n            \/\/ The leading _'s are to avoid dead code warnings if this is\n            \/\/ used inside a dead function.

In doing so, the liblog crate was linked against the real\n\/\/ version of libstd, and uses a different std::fmt module than the test crate\n\/\/ uses. To get around this difference, we redefine the log!() macro here to be\n\/\/ just a dumb version of what it should be.\n#[cfg(test)]\nmacro_rules! log {\n    ($lvl:expr, $($args:tt)*) => (\n        if log_enabled!($lvl) { println!($($args)*) }\n    )\n}\n\n\/\/\/ Built-in macros to the compiler itself.\n\/\/\/\n\/\/\/ These macros do not have any corresponding definition with a `macro_rules!`\n\/\/\/ macro, but are documented here.

This modules contains a set of macros which are exported from the standard\n\/\/! library. Each macro is available for use when linking against the standard\n\/\/! library.\n\n#![unstable(feature = \"std_misc\")]\n\n\/\/\/ The entry point for panic of Rust tasks.\n\/\/\/\n\/\/\/ This macro is used to inject panic into a Rust task, causing the task to\n\/\/\/ unwind and panic entirely. Each task's panic can be reaped as the\n\/\/\/ `Box<Any>` type, and the single-argument form of the `panic!` macro will be\n\/\/\/ the value which is transmitted.\n\/\/\/\n\/\/\/ The multi-argument form of this macro panics with a string and has the\n\/\/\/ `format!` syntax for building a string.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```should_fail\n\/\/\/ # #![allow(unreachable_code)]\n\/\/\/ panic!();\n\/\/\/ panic!(\"this is a terrible mistake!\");\n\/\/\/ panic!(4); \/\/ panic with the value of 4 to be collected elsewhere\n\/\/\/ panic!(\"this is a {} {message}\", \"fancy\", message = \"message\");\n\/\/\/ ```\n#[macro_export]\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\nmacro_rules! panic {\n    () => ({\n        panic!(\"explicit panic\")\n    });\n    ($msg:expr) => ({\n        $crate::rt::begin_unwind($msg, {\n            \/\/ static requires less code at runtime, more constant data\n            static _FILE_LINE: (&'static str, usize) = (file!(), line!() as usize);\n            &_FILE_LINE\n        })\n    });\n    ($fmt:expr, $($arg:tt)+) => ({\n        $crate::rt::begin_unwind_fmt(format_args!($fmt, $($arg)+), {\n            \/\/ The leading _'s are to avoid dead code warnings if this is\n            \/\/ used inside a dead function.

It places no restrictions on the types of receivers given to\n\/\/\/ this macro, this can be viewed as a heterogeneous select.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::thread;\n\/\/\/ use std::sync::mpsc;\n\/\/\/\n\/\/\/ \/\/ two placeholder functions for now\n\/\/\/ fn long_running_task() {}\n\/\/\/ fn calculate_the_answer() -> u32 { 42 }\n\/\/\/\n\/\/\/ let (tx1, rx1) = mpsc::channel();\n\/\/\/ let (tx2, rx2) = mpsc::channel();\n\/\/\/\n\/\/\/ thread::spawn(move|| { long_running_task(); tx1.send(()).unwrap(); });\n\/\/\/ thread::spawn(move|| { tx2.send(calculate_the_answer()).unwrap(); });\n\/\/\/\n\/\/\/ select!

In doing so, the liblog crate was linked against the real\n\/\/ version of libstd, and uses a different std::fmt module than the test crate\n\/\/ uses. To get around this difference, we redefine the log!() macro here to be\n\/\/ just a dumb version of what it should be.\n#[cfg(test)]\nmacro_rules! log {\n    ($lvl:expr, $($args:tt)*) => (\n        if log_enabled!($lvl) { println!($($args)*) }\n    )\n}\n\n\/\/\/ Built-in macros to the compiler itself.\n\/\/\/\n\/\/\/ These macros do not have any corresponding definition with a `macro_rules!`\n\/\/\/ macro, but are documented here. Their implementations can be found hardcoded\n\/\/\/ into libsyntax itself.\n#[cfg(dox)]\npub mod builtin {\n    \/\/\/ The core macro for formatted string creation & output.\n    \/\/\/\n    \/\/\/ This macro produces a value of type `fmt::Arguments`.

Note that hygiene makes it such that this macro cannot\n    \/\/\/ capture local variables, and macros are only allowed in item,\n    \/\/\/ statement or expression position, meaning this macro may be difficult to\n    \/\/\/ use in some situations.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ #![feature(concat_idents)]\n    \/\/\/\n    \/\/\/ # fn main() {\n    \/\/\/ fn foobar() -> u32 { 23 }\n    \/\/\/\n    \/\/\/ let f = concat_idents!(foo, bar);\n    \/\/\/ println!(\"{}\", f());\n    \/\/\/ # }\n    \/\/\/ ```\n    #[macro_export]\n    macro_rules! concat_idents {\n        ($($e:ident),*) => ({ \/* compiler built-in *\/ })\n    }\n\n    \/\/\/ Concatenates literals into a static string slice.\n    \/\/\/\n    \/\/\/ This macro takes any number of comma-separated literals, yielding an\n    \/\/\/ expression of type `&'static str` which represents all of the literals\n    \/\/\/ concatenated left-to-right.\n    \/\/\/\n    \/\/\/ Integer and floating point literals are stringified in order to be\n    \/\/\/ concatenated.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let s = concat!(\"test\", 10, 'b', true);\n    \/\/\/ assert_eq!(s, \"test10btrue\");\n    \/\/\/ ```\n    #[macro_export]\n    macro_rules! concat { ($($e:expr),*) => ({ \/* compiler built-in *\/ }) }\n\n    \/\/\/ A macro which expands to the line number on which it was invoked.\n    \/\/\/\n    \/\/\/ The expanded expression has type `usize`, and the returned line is not\n    \/\/\/ the invocation of the `line!()` macro itself, but rather the first macro\n    \/\/\/ invocation leading up to the invocation of the `line!()` macro.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let current_line = line!();\n    \/\/\/ println!(\"defined on line: {}\", current_line);\n    \/\/\/ ```\n    #[macro_export]\n    macro_rules! line { () => ({ \/* compiler built-in *\/ }) }\n\n    \/\/\/ A macro which expands to the column number on which it was invoked.\n    \/\/\/\n    \/\/\/ The expanded expression has type `usize`, and the returned column is not\n    \/\/\/ the invocation of the `column!()` macro itself, but rather the first macro\n    \/\/\/ invocation leading up to the invocation of the `column!()` macro.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let current_col = column!();\n    \/\/\/ println!(\"defined on column: {}\", current_col);\n    \/\/\/ ```\n    #[macro_export]\n    macro_rules! column { () => ({ \/* compiler built-in *\/ }) }\n\n    \/\/\/ A macro which expands to the file name from which it was invoked.\n    \/\/\/\n    \/\/\/ The expanded expression has type `&'static str`, and the returned file\n    \/\/\/ is not the invocation of the `file!()` macro itself, but rather the\n    \/\/\/ first macro invocation leading up to the invocation of the `file!()`\n    \/\/\/ macro.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let this_file = file!();\n    \/\/\/ println!(\"defined in file: {}\", this_file);\n    \/\/\/ ```\n    #[macro_export]\n    macro_rules! file { () => ({ \/* compiler built-in *\/ }) }\n\n    \/\/\/ A macro which stringifies its argument.\n    \/\/\/\n    \/\/\/ This macro will yield an expression of type `&'static str` which is the\n    \/\/\/ stringification of all the tokens passed to the macro.

signal that the strem has ended. The `Err` variant\n\/\/\/ contains the error that a stream encounterd, if any.\npub type StreamResult<T, E> = Result<Option<T>, E>;\n\n\/\/\/ A stream of values, not all of which have been produced yet.\n\/\/\/\n\/\/\/ `Stream` is a trait to represent any source of sequential events or items\n\/\/\/ which acts like an iterator but may block over time. Like `Future` the\n\/\/\/ methods of `Stream` never block and it is thus suitable for programming in\n\/\/\/ an asynchronous fashion. This trait is very similar to the `Iterator` trait\n\/\/\/ in the standard library where `Some` is used to signal elements of the\n\/\/\/ stream and `None` is used to indicate that the stream is finished.\n\/\/\/\n\/\/\/ Like futures a stream has basic combinators to transform the stream, perform\n\/\/\/ more work on each item, etc.\n\/\/\/\n\/\/\/ # Basic methods\n\/\/\/\n\/\/\/ Like futures, a `Stream` has two core methods which drive processing of data\n\/\/\/ and notifications of when new data might be ready. The `poll` method checks\n\/\/\/ the status of a stream and the `schedule` method is used to receive\n\/\/\/ notifications for when it may be ready to call `poll` again.\n\/\/\/\n\/\/\/ Also like future, a stream has an associated error type to represent that an\n\/\/\/ element of the computation failed for some reason.

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested up into inputs and\n* outputs, and subdivides those into declared (input) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase. Even when a function's\n* work-doing part (the \"exec\" phase) never gets called, it has declared\n* inputs, which can be checked for freshness (and potentially\n* used to determine that the function can be skipped).\n*\n* The workcache checks _all_ works for freshness, but uses the set of\n* discovered outputs from the _previous_ exec (which it will re-discover\n* and re-record each time the exec phase runs).\n*\n* Therefore the discovered works cached in the db might be a\n* mis-approximation of the current discoverable works, but this is ok for\n* the following reason: we assume that if an artifact A changed from\n* depending on B,C,D to depending on B,C,D,E, then A itself changed (as\n* part of the change-in-dependencies), so we will be ok.\n*\n* Each function has a single discriminated output work called its _result_.\n* This is only different from other works in that it is returned, by value,\n* from a call to the cacheable function; the other output works are used in\n* passing to invalidate dependencies elsewhere in the cache, but do not\n* otherwise escape from a function invocation. Most functions only have one\n* output work anyways.\n*\n* A database (the central store of a workcache) stores a mappings:\n*\n* (fn_name,{declared_input}) => ({discovered_input},\n*                                {discovered_output},result)\n*\n* (Note: fbuild, which workcache is based on, has the concept of a declared\n* output as separate from a discovered output. This distinction exists only\n* as an artifact of how fbuild works: via annotations on function types\n* and metaprogramming, with explicit dependency declaration as a fallback.\n* Workcache is more explicit about dependencies, and as such treats all\n* outputs the same, as discovered-during-the-last-run.)\n*\n*\/\n\n#[deriving(Eq)]\n#[auto_encode]\n#[auto_decode]\nstruct WorkKey {\n    kind:

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested in into inputs and\n* outputs, and subdivides those into declared (input) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase. Even when a function's\n* work-doing part (the \"exec\" phase) never gets called, it has declared\n* inputs, which can be checked for freshness (and potentially\n* used to determine that the function can be skipped).\n*\n* The workcache checks _all_ works for freshness, but uses the set of\n* discovered outputs from the _previous_ exec (which it will re-discover\n* and re-record each time the exec phase runs).\n*\n* Therefore the discovered works cached in the db might be a\n* mis-approximation of the current discoverable works, but this is ok for\n* the following reason: we assume that if an artifact A changed from\n* depending on B,C,D to depending on B,C,D,E, then A itself changed (as\n* part of the change-in-dependencies), so we will be ok.\n*\n* Each function has a single discriminated output work called its _result_.\n* This is only different from other works in that it is returned, by value,\n* from a call to the cacheable function; the other output works are used in\n* passing to invalidate dependencies elsewhere in the cache, but do not\n* otherwise escape from a function invocation. Most functions only have one\n* output work anyways.\n*\n* A database (the central store of a workcache) stores a mappings:\n*\n* (fn_name,{declared_input}) => ({discovered_input},\n*                                {discovered_output},result)\n*\n* (Note: fbuild, which workcache is based on, has the concept of a declared\n* output as separate from a discovered output. This distinction exists only\n* as an artifact of how fbuild works: via annotations on function types\n* and metaprogramming, with explicit dependency declaration as a fallback.\n* Workcache is more explicit about dependencies, and as such treats all\n* outputs the same, as discovered-during-the-last-run.)\n*\n*\/\n\n#[deriving(Eq)]\n#[auto_encode]\n#[auto_decode]\nstruct WorkKey {\n    kind:

This module provides an implementation of OS-based thread local storage,\n\/\/! using the native OS-provided facilities (think `TlsAlloc` or\n\/\/! `pthread_setspecific`). The interface of this differs from the other types\n\/\/! of thread-local-storage provided in this crate in that OS-based TLS can only\n\/\/! get\/set pointers,\n\/\/!\n\/\/! This module also provides two flavors of TLS. One is intended for static\n\/\/! initialization, and does not contain a `Drop` implementation to deallocate\n\/\/! the OS-TLS key. The other is a type which does implement `Drop` and hence\n\/\/! has a safe interface.\n\/\/!\n\/\/! # Usage\n\/\/!\n\/\/! This module should likely not be used directly unless other primitives are\n\/\/! being built on. types such as `thread_local::scoped::Key` are likely much\n\/\/! more useful in practice than this OS-based version which likely requires\n\/\/! unsafe code to interoperate with.\n\/\/!\n\/\/! # Example\n\/\/!\n\/\/! Using a dynamically allocated TLS key. Note that this key can be shared\n\/\/! among many threads via an `Arc`.\n\/\/!\n\/\/! ```rust,ignore\n\/\/! let key = Key::new(None);\n\/\/! assert!(key.get().is_null());\n\/\/! key.set(1 as *mut u8);\n\/\/! assert!(!key.get().is_null());\n\/\/!\n\/\/! drop(key); \/\/ deallocate this TLS slot.\n\/\/! ```\n\/\/!\n\/\/!

The other is a type which does implement `Drop` and hence\n\/\/! has a safe interface.\n\/\/!\n\/\/! # Usage\n\/\/!\n\/\/! This module should likely not be used directly unless other primitives are\n\/\/! being built on. types such as `thread_local::scoped::Key` are likely much\n\/\/! more useful in practice than this OS-based version which likely requires\n\/\/! unsafe code to interoperate with.\n\/\/!\n\/\/! # Example\n\/\/!\n\/\/! Using a dynamically allocated TLS key. Note that this key can be shared\n\/\/! among many threads via an `Arc`.\n\/\/!\n\/\/! ```rust,ignore\n\/\/! let key = Key::new(None);\n\/\/! assert!(key.get().is_null());\n\/\/! key.set(1 as *mut u8);\n\/\/! assert!(!key.get().is_null());\n\/\/!\n\/\/! drop(key); \/\/ deallocate this TLS slot.\n\/\/! ```\n\/\/!\n\/\/! Sometimes a statically allocated key is either required or easier to work\n\/\/! with, however.\n\/\/!\n\/\/! ```rust,ignore\n\/\/! static KEY: StaticKey = INIT;\n\/\/!\n\/\/! unsafe {\n\/\/!     assert!(KEY.get().is_null());\n\/\/!     KEY.set(1 as *mut u8);\n\/\/! }\n\/\/! ```\n\n#![allow(non_camel_case_types)]\n\nuse prelude::*;\n\nuse kinds::marker;\nuse rustrt::exclusive::Exclusive;\nuse sync::atomic::{mod, AtomicUint};\nuse sync::{Once, ONCE_INIT};\n\nuse sys::thread_local as imp;\n\n\/\/\/ A type for TLS keys that are statically allocated.\n\/\/\/\n\/\/\/ This type is entirely `unsafe` to use as it does not protect against\n\/\/\/ use-after-deallocation or use-during-deallocation.\n\/\/\/\n\/\/\/ The actual OS-TLS key is lazily allocated when this is used for the first\n\/\/\/ time.

Traits for working with Errors.\n\/\/!\n\/\/! # The `Error` trait\n\/\/!\n\/\/! `Error` is a trait representing the basic expectations for error values,\n\/\/! i.e. values of type `E` in `Result<T, E>`. At a minimum, errors must provide\n\/\/! a description, but they may optionally provide additional detail (via\n\/\/! `Display`) and cause chain information:\n\/\/!\n\/\/! ```\n\/\/! use std::fmt::Display;\n\/\/!\n\/\/! trait Error: Display {\n\/\/!     fn description(&self) -> &str;\n\/\/!\n\/\/!     fn cause(&self) -> Option<&Error> { None }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! The `cause` method is generally used when errors cross \"abstraction\n\/\/! boundaries\", i.e.  when a one module must report an error that is \"caused\"\n\/\/! by an error from a lower-level module. This setup makes it possible for the\n\/\/! high-level module to provide its own errors that do not commit to any\n\/\/! particular implementation, but also reveal some of its implementation for\n\/\/! debugging via `cause` chains.\n\/\/!\n\/\/! # The `FromError` trait\n\/\/!\n\/\/! `FromError` is a simple trait that expresses conversions between different\n\/\/! error types. To provide maximum flexibility, it does not require either of\n\/\/! the types to actually implement the `Error` trait, although this will be the\n\/\/! common case.\n\/\/!\n\/\/! The main use of this trait is in the `try!` macro, which uses it to\n\/\/! automatically convert a given error to the error specified in a function's\n\/\/! return type.\n\/\/!\n\/\/!

handling approach, except that Rust\n\/\/ does have a single \"catch-all\" handler at the bottom of each thread's stack.\n\/\/ So we have two versions of the personality routine:\n\/\/ - rust_eh_personality, used by all cleanup landing pads, which never catches,\n\/\/   so the behavior of __gcc_personality_v0 is perfectly adequate there, and\n\/\/ - rust_eh_personality_catch, used only by rust_try(), which always catches.\n\/\/\n\/\/ See also: rustc_trans::trans::intrinsic::trans_gnu_try\n\n#[cfg(all(not(target_arch = \"arm\"),\n          not(all(windows, target_arch =

Persistent and prunable Merkle Mountain Range implementation. For a high\n\/\/! level description of MMRs, see:\n\/\/!\n\/\/! https:\/\/github.com\/opentimestamps\/opentimestamps-server\/blob\/master\/doc\/merkle-mountain-range.md\n\/\/!\n\/\/! This implementation is built in two major parts:\n\/\/!\n\/\/! 1. A set of low-level functions that allow navigation within an arbitrary\n\/\/! sized binary tree traversed in postorder. To realize why this us useful,\n\/\/! we start with the standard height sequence in a MMR: 0010012001... This is\n\/\/! in fact identical to the postorder traversal (left-right-top) of a binary\n\/\/! tree. In addition postorder traversal is independent of the height of the\n\/\/! tree. This allows us, with a few primitive, to get the height of any node\n\/\/! in the MMR from its position in the sequence, as well as calculate the\n\/\/! position of siblings, parents, etc. As all those functions only rely on\n\/\/! binary operations, they're extremely fast. For more information, see the\n\/\/! doc on bintree_jump_left_sibling.\n\/\/! 2. The implementation of a prunable MMR sum tree using the above. Each leaf\n\/\/! is required to be Summable and Hashed. Tree roots can be trivially and\n\/\/! efficiently calculated without materializing the full tree. The underlying\n\/\/! (Hash, Sum) pais are stored in a Backend implementation that can either be\n\/\/! a simple Vec or a database.\n\nuse std::clone::Clone;\nuse std::fmt::Debug;\nuse std::marker::PhantomData;\nuse std::ops::{self, Deref};\n\nuse core::hash::{Hash, Hashed};\nuse ser::{self, Readable, Reader, Writeable, Writer};\n\n\/\/\/ Trait for an element of the tree that has a well-defined sum and hash that\n\/\/\/ the tree can sum over\npub trait Summable {\n\t\/\/\/ The type of the sum\n\ttype Sum: Clone + ops::Add<Output = Self::Sum> + Readable + Writeable;\n\n\t\/\/\/ Obtain the sum of the element\n\tfn sum(&self) -> Self::Sum;\n\n\t\/\/\/ Length of the Sum type when serialized.

Specifically, we want to be able to generate the following\n\/\/\/ sequence:\n\/\/\/\n\/\/\/ \/\/    [0, 0, 1, 0, 0, 1, 2, 0, 0, 1, 0, 0, 1, 2, 3, 0, 0, 1, ...]\n\/\/\/\n\/\/\/ Which turns out to start as the heights in the (left, right, top)\n\/\/\/ -postorder- traversal of the following tree:\n\/\/\/\n\/\/\/ \/\/               3\n\/\/\/ \/\/             \/   \\\n\/\/\/ \/\/           \/       \\\n\/\/\/ \/\/         \/           \\\n\/\/\/ \/\/        2             2\n\/\/\/ \/\/      \/  \\          \/  \\\n\/\/\/ \/\/     \/    \\        \/    \\\n\/\/\/ \/\/    1      1      1      1\n\/\/\/ \/\/   \/ \\    \/ \\    \/ \\    \/ \\\n\/\/\/ \/\/  0   0  0   0  0   0  0   0\n\/\/\/\n\/\/\/ If we extend this tree up to a height of 4, we can continue the sequence,\n\/\/\/ and for an infinitely high tree, we get the infinite sequence of heights\n\/\/\/ in the MMR.\n\/\/\/\n\/\/\/ So to generate the MMR height sequence, we want a function that, given an\n\/\/\/ index in that sequence, gets us the height in the tree. This allows us to\n\/\/\/ build the sequence not only to infinite, but also at any index, without the\n\/\/\/ need to materialize the beginning of the sequence.\n\/\/\/\n\/\/\/ To see how to get the height of a node at any position in the postorder\n\/\/\/ traversal sequence of heights, we start by rewriting the previous tree with\n\/\/\/ each the position of every node written in binary:\n\/\/\/\n\/\/\/\n\/\/\/ \/\/                  1111\n\/\/\/ \/\/                 \/   \\\n\/\/\/ \/\/               \/       \\\n\/\/\/ \/\/             \/           \\\n\/\/\/ \/\/           \/               \\\n\/\/\/ \/\/        111                1110\n\/\/\/ \/\/       \/   \\              \/    \\\n\/\/\/ \/\/      \/     \\            \/      \\\n\/\/\/ \/\/     11      110        1010     1101\n\/\/\/ \/\/    \/ \\      \/ \\       \/  \\      \/ \\\n\/\/\/ \/\/   1   10  100  101  1000 1001 1011 1100\n\/\/\/\n\/\/\/ The height of a node is the number of 1 digits on the leftmost branch of\n\/\/\/ the tree, minus 1. For example, 1111 has 4 ones, so its height is `4-1=3`.\n\/\/\/\n\/\/\/ To get the height of any node (say 1101), we need to travel left in the\n\/\/\/ tree, get the leftmost node and count the ones. To travel left, we just\n\/\/\/ need to subtract the position by it's most significant bit, mins one. For\n\/\/\/ example to get from 1101 to 110 we subtract it by (1000-1) (`13-(8-1)=5`).\n\/\/\/ Then to to get 110 to 11, we subtract it by (100-1) ('6-(4-1)=3`).\n\/\/\/\n\/\/\/ By applying this operation recursively, until we get a number that, in\n\/\/\/ binary, is all ones, and then counting the ones, we can get the height of\n\/\/\/ any node, from its postorder traversal position. Which is the order in which\n\/\/\/ nodes are added in a MMR.\n\/\/\/\n\/\/\/ [1]  https:\/\/github.com\/opentimestamps\/opentimestamps-server\/blob\/master\/doc\/merkle-mountain-range.md\nfn

Traits for working with Errors.\n\/\/!\n\/\/! # The `Error` trait\n\/\/!\n\/\/! `Error` is a trait representing the basic expectations for error values,\n\/\/! i.e. values of type `E` in `Result<T, E>`. At a minimum, errors must provide\n\/\/! a description, but they may optionally provide additional detail (via\n\/\/! `Display`) and cause chain information:\n\/\/!\n\/\/! ```\n\/\/! use std::fmt::Display;\n\/\/!\n\/\/! trait Error: Display {\n\/\/!     fn description(&self) -> &str;\n\/\/!\n\/\/!     fn cause(&self) -> Option<&Error> { None }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! The `cause` method is generally used when errors cross \"abstraction\n\/\/! boundaries\", i.e.  when a one module must report an error that is \"caused\"\n\/\/! by an error from a lower-level module. This setup makes it possible for the\n\/\/! high-level module to provide its own errors that do not commit to any\n\/\/! particular implementation, but also reveal some of its implementation for\n\/\/! debugging via `cause` chains.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/ A note about crates and the facade:\n\/\/\n\/\/ Originally, the `Error` trait was defined in libcore, and the impls\n\/\/ were scattered about. However, coherence objected to this\n\/\/ arrangement, because to create the blanket impls for `Box` required\n\/\/ knowing that `&str: !Error`, and we have no means to deal with that\n\/\/ sort of conflict just now. Therefore, for the time being, we have\n\/\/ moved the `Error` trait into libstd. As we evolve a sol'n to the\n\/\/ coherence challenge (e.g., specialization, neg impls, etc) we can\n\/\/ reconsider what crate these items belong in.\n\nuse any::TypeId;\nuse boxed::Box;\nuse

At a minimum, errors must provide\n\/\/! a description, but they may optionally provide additional detail (via\n\/\/! `Display`) and cause chain information:\n\/\/!\n\/\/! ```\n\/\/! use std::fmt::Display;\n\/\/!\n\/\/! trait Error: Display {\n\/\/!     fn description(&self) -> &str;\n\/\/!\n\/\/!     fn cause(&self) -> Option<&Error> { None }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! The `cause` method is generally used when errors cross \"abstraction\n\/\/! boundaries\", i.e.  when a one module must report an error that is \"caused\"\n\/\/! by an error from a lower-level module. This setup makes it possible for the\n\/\/! high-level module to provide its own errors that do not commit to any\n\/\/! particular implementation, but also reveal some of its implementation for\n\/\/! debugging via `cause` chains.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/ A note about crates and the facade:\n\/\/\n\/\/ Originally, the `Error` trait was defined in libcore, and the impls\n\/\/ were scattered about. However, coherence objected to this\n\/\/ arrangement, because to create the blanket impls for `Box` required\n\/\/ knowing that `&str: !Error`, and we have no means to deal with that\n\/\/ sort of conflict just now. Therefore, for the time being, we have\n\/\/ moved the `Error` trait into libstd. As we evolve a sol'n to the\n\/\/ coherence challenge (e.g., specialization, neg impls, etc) we can\n\/\/ reconsider what crate these items belong in.\n\nuse any::TypeId;\nuse boxed::Box;\nuse

The\n\/\/\/ purpose of this trait is to encode what types are safe to cross a `recover`\n\/\/\/ boundary with no fear of panic safety.\n\/\/\/\n\/\/\/ ## What is panic safety?\n\/\/\/\n\/\/\/ In Rust a function can \"return\" early if it either panics or calls a\n\/\/\/ function which transitively panics. This sort of control flow is not always\n\/\/\/ anticipated, and has the possibility of causing subtle bugs through a\n\/\/\/ combination of two cricial components:\n\/\/\/\n\/\/\/ 1. A data structure is in a temporarily invalid state when the thread\n\/\/\/    panics.\n\/\/\/ 2. This broken invariant is then later observed.\n\/\/\/\n\/\/\/ Typically in Rust, it is difficult to perform step (2) because catching a\n\/\/\/ panic involves either spawning a thread (which in turns makes it difficult\n\/\/\/ to later witness broken invariants) or using the `recover` function in this\n\/\/\/ module. Additionally, even if an invariant is witnessed, it typically isn't a\n\/\/\/ problem in Rust because there's no uninitialized values (like in C or C++).\n\/\/\/\n\/\/\/ It is possible, however, for **logical** invariants to be broken in Rust,\n\/\/\/ which can end up causing behavioral bugs. Another key aspect of panic safety\n\/\/\/ in Rust is that, in the absence of `unsafe` code, a panic cannot lead to\n\/\/\/ memory unsafety.\n\/\/\/\n\/\/\/ That was a bit of a whirlwind tour of panic safety, but for more information\n\/\/\/ about panic safety and how it applies to Rust, see an [associated RFC][rfc].\n\/\/\/\n\/\/\/ [rfc]: https:\/\/github.com\/rust-lang\/rfcs\/blob\/master\/text\/1236-stabilize-catch-panic.md\n\/\/\/\n\/\/\/ ## What is `RecoverSafe`?\n\/\/\/\n\/\/\/ Now that we've got an idea of what panic safety is in Rust, it's also\n\/\/\/ important to understand what this trait represents. As mentioned above, one\n\/\/\/ way to witness broken invariants is through the `recover` function in this\n\/\/\/ module as it allows catching a panic and then re-using the environment of\n\/\/\/ the closure.\n\/\/\/\n\/\/\/ Simply put, a type `T` implements `RecoverSafe` if it cannot easily allow\n\/\/\/ witnessing a broken invariant through the use of `recover` (catching a\n\/\/\/ panic). This trait is a marker trait, so it is automatically implemented for\n\/\/\/ many types, and it is also structurally composed (e.g. a struct is recover\n\/\/\/ safe if all of its components are recover safe).\n\/\/\/\n\/\/\/ Note, however, that this is not an unsafe trait, so there is not a succinct\n\/\/\/ contract that this trait is providing. Instead it is intended as more of a\n\/\/\/ \"speed bump\" to alert users of `recover` that broken invariants may be\n\/\/\/ witnessed and may need to be accounted for.\n\/\/\/\n\/\/\/ ## Who implements `RecoverSafe`?\n\/\/\/\n\/\/\/ Types such as `&mut T` and `&RefCell<T>` are examples which are **not**\n\/\/\/ recover safe. The general idea is that any mutable state which can be shared\n\/\/\/ across `recover` is not recover safe by default. This is because it is very\n\/\/\/ easy to witness a broken invariant outside of `recover` as the data is\n\/\/\/ simply accesed as usual.\n\/\/\/\n\/\/\/ Types like `&Mutex<T>`, however, are recover safe because they implement\n\/\/\/ poisoning by default. They still allow witnessing a broken invariant, but\n\/\/\/ they already provide their own \"speed bumps\" to do so.\n\/\/\/\n\/\/\/ ## When should `RecoverSafe` be used?\n\/\/\/\n\/\/\/ Is not intended that most types or functions need to worry about this trait.\n\/\/\/ It is only used as a bound on the `recover` function and as mentioned above,\n\/\/\/ the lack of `unsafe` means it is mostly an advisory. The `AssertRecoverSafe`\n\/\/\/ wrapper struct in this module can be used to force this trait to be\n\/\/\/ implemented for any closed over variables passed to the `recover` function\n\/\/\/ (more on this below).\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} may not be safely transferred \\\n                            across a recover boundary\"]\npub trait RecoverSafe {}\n\n\/\/\/ A marker trait representing types where a shared reference is considered\n\/\/\/ recover safe.\n\/\/\/\n\/\/\/ This trait is namely not implemented by `UnsafeCell`, the root of all\n\/\/\/ interior mutability.\n\/\/\/\n\/\/\/ This is a \"helper marker trait\" used to provide impl blocks for the\n\/\/\/ `RecoverSafe` trait, for more information see that documentation.\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} contains interior mutability \\\n                            and a reference may not be safely transferrable \\\n                            across a recover boundary\"]\npub trait RefRecoverSafe {}\n\n\/\/\/ A simple wrapper around a type to assert that it is panic safe.\n\/\/\/\n\/\/\/ When using `recover` it may be the case that some of the closed over\n\/\/\/ variables are not panic safe.

The\n\/\/\/ purpose of this trait is to encode what types are safe to cross a `recover`\n\/\/\/ boundary with no fear of panic safety.\n\/\/\/\n\/\/\/ ## What is panic safety?\n\/\/\/\n\/\/\/ In Rust a function can \"return\" early if it either panics or calls a\n\/\/\/ function which transitively panics. This sort of control flow is not always\n\/\/\/ anticipated, and has the possibility of causing subtle bugs through a\n\/\/\/ combination of two cricial components:\n\/\/\/\n\/\/\/ 1. A data structure is in a temporarily invalid state when the thread\n\/\/\/    panics.\n\/\/\/ 2. This broken invariant is then later observed.\n\/\/\/\n\/\/\/ Typically in Rust, it is difficult to perform step (2) because catching a\n\/\/\/ panic involves either spawning a thread (which in turns makes it difficult\n\/\/\/ to later witness broken invariants) or using the `recover` function in this\n\/\/\/ module. Additionally, even if an invariant is witnessed, it typically isn't a\n\/\/\/ problem in Rust because there's no uninitialized values (like in C or C++).\n\/\/\/\n\/\/\/ It is possible, however, for **logical** invariants to be broken in Rust,\n\/\/\/ which can end up causing behavioral bugs. Another key aspect of panic safety\n\/\/\/ in Rust is that, in the absence of `unsafe` code, a panic cannot lead to\n\/\/\/ memory unsafety.\n\/\/\/\n\/\/\/ That was a bit of a whirlwind tour of panic safety, but for more information\n\/\/\/ about panic safety and how it applies to Rust, see an [associated RFC][rfc].\n\/\/\/\n\/\/\/ [rfc]: https:\/\/github.com\/rust-lang\/rfcs\/blob\/master\/text\/1236-stabilize-catch-panic.md\n\/\/\/\n\/\/\/ ## What is `RecoverSafe`?\n\/\/\/\n\/\/\/ Now that we've got an idea of what panic safety is in Rust, it's also\n\/\/\/ important to understand what this trait represents. As mentioned above, one\n\/\/\/ way to witness broken invariants is through the `recover` function in this\n\/\/\/ module as it allows catching a panic and then re-using the environment of\n\/\/\/ the closure.\n\/\/\/\n\/\/\/ Simply put, a type `T` implements `RecoverSafe` if it cannot easily allow\n\/\/\/ witnessing a broken invariant through the use of `recover` (catching a\n\/\/\/ panic). This trait is a marker trait, so it is automatically implemented for\n\/\/\/ many types, and it is also structurally composed (e.g. a struct is recover\n\/\/\/ safe if all of its components are recover safe).\n\/\/\/\n\/\/\/ Note, however, that this is not an unsafe trait, so there is not a succinct\n\/\/\/ contract that this trait is providing. Instead it is intended as more of a\n\/\/\/ \"speed bump\" to alert users of `recover` that broken invariants may be\n\/\/\/ witnessed and may need to be accounted for.\n\/\/\/\n\/\/\/ ## Who implements `RecoverSafe`?\n\/\/\/\n\/\/\/ Types such as `&mut T` and `&RefCell<T>` are examples which are **not**\n\/\/\/ recover safe. The general idea is that any mutable state which can be shared\n\/\/\/ across `recover` is not recover safe by default. This is because it is very\n\/\/\/ easy to witness a broken invariant outside of `recover` as the data is\n\/\/\/ simply accesed as usual.\n\/\/\/\n\/\/\/ Types like `&Mutex<T>`, however, are recover safe because they implement\n\/\/\/ poisoning by default. They still allow witnessing a broken invariant, but\n\/\/\/ they already provide their own \"speed bumps\" to do so.\n\/\/\/\n\/\/\/ ## When should `RecoverSafe` be used?\n\/\/\/\n\/\/\/ Is not intended that most types or functions need to worry about this trait.\n\/\/\/ It is only used as a bound on the `recover` function and as mentioned above,\n\/\/\/ the lack of `unsafe` means it is mostly an advisory. The `AssertRecoverSafe`\n\/\/\/ wrapper struct in this module can be used to force this trait to be\n\/\/\/ implemented for any closed over variables passed to the `recover` function\n\/\/\/ (more on this below).\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} may not be safely transferred \\\n                            across a recover boundary\"]\npub trait RecoverSafe {}\n\n\/\/\/ A marker trait representing types where a shared reference is considered\n\/\/\/ recover safe.\n\/\/\/\n\/\/\/ This trait is namely not implemented by `UnsafeCell`, the root of all\n\/\/\/ interior mutability.\n\/\/\/\n\/\/\/ This is a \"helper marker trait\" used to provide impl blocks for the\n\/\/\/ `RecoverSafe` trait, for more information see that documentation.\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} contains interior mutability \\\n                            and a reference may not be safely transferrable \\\n                            across a recover boundary\"]\npub trait RefRecoverSafe {}\n\n\/\/\/ A simple wrapper around a type to assert that it is panic safe.\n\/\/\/\n\/\/\/ When using `recover` it may be the case that some of the closed over\n\/\/\/ variables are not panic safe.

In general, there may be several ways to \"borrow\" a piece of data.  The\n\/\/! typical ways of borrowing a type `T` are `&T` (a shared borrow) and `&mut T`\n\/\/! (a mutable borrow). But types like `Vec<T>` provide additional kinds of\n\/\/! borrows: the borrowed slices `&[T]` and `&mut [T]`.\n\/\/!\n\/\/! When writing generic code, it is often desirable to abstract over all ways\n\/\/! of borrowing data from a given type. That is the role of the `BorrowFrom`\n\/\/! trait: if `T: BorrowFrom<U>`, then `&T` can be borrowed from `&U`.  A given\n\/\/! type can be borrowed as multiple different types. In particular, `Vec<T>:\n\/\/! BorrowFrom<Vec<T>>` and `[T]: BorrowFrom<Vec<T>>`.\n\/\/!\n\/\/! # The `ToOwned` trait\n\/\/!\n\/\/! Some types make it possible to go from borrowed to owned, usually by\n\/\/! implementing the `Clone` trait. But `Clone` works only for going from `&T`\n\/\/! to `T`. The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/! from any borrow of a given type.\n\/\/!\n\/\/! # The `Cow` (clone-on-write) type\n\/\/!\n\/\/! The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/! can enclose and provide immutable access to borrowed data, and clone the\n\/\/! data lazily when mutation or ownership is required. The type is designed to\n\/\/! work with general borrowed data via the `BorrowFrom` trait.\n\/\/!\n\/\/! `Cow` implements both `Deref` and `DerefMut`, which means that you can call\n\/\/! methods directly on the data it encloses. The first time a mutable reference\n\/\/! is required, the data will be cloned (via `to_owned`) if it is not\n\/\/! already owned.\n\n#![unstable = \"recently added as part of collections reform\"]\n\nuse clone::Clone;\nuse kinds::Sized;\nuse ops::Deref;\nuse self::Cow::*;\n\n\/\/\/ A trait for borrowing data.\npub trait BorrowFrom<Sized?

In general, there may be several ways to \"borrow\" a piece of data.  The\n\/\/! typical ways of borrowing a type `T` are `&T` (a shared borrow) and `&mut T`\n\/\/! (a mutable borrow). But types like `Vec<T>` provide additional kinds of\n\/\/! borrows: the borrowed slices `&[T]` and `&mut [T]`.\n\/\/!\n\/\/! When writing generic code, it is often desirable to abstract over all ways\n\/\/! of borrowing data from a given type. That is the role of the `BorrowFrom`\n\/\/! trait: if `T: BorrowFrom<U>`, then `&T` can be borrowed from `&U`.  A given\n\/\/! type can be borrowed as multiple different types. In particular, `Vec<T>:\n\/\/! BorrowFrom<Vec<T>>` and `[T]: BorrowFrom<Vec<T>>`.\n\/\/!\n\/\/! # The `ToOwned` trait\n\/\/!\n\/\/! Some types make it possible to go from borrowed to owned, usually by\n\/\/! implementing the `Clone` trait. But `Clone` works only for going from `&T`\n\/\/! to `T`. The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/! from any borrow of a given type.\n\/\/!\n\/\/! # The `Cow` (clone-on-write) type\n\/\/!\n\/\/! The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/! can enclose and provide immutable access to borrowed data, and clone the\n\/\/! data lazily when mutation or ownership is required. The type is designed to\n\/\/! work with general borrowed data via the `BorrowFrom` trait.\n\/\/!\n\/\/! `Cow` implements both `Deref` and `DerefMut`, which means that you can call\n\/\/! methods directly on the data it encloses. The first time a mutable reference\n\/\/! is required, the data will be cloned (via `to_owned`) if it is not\n\/\/! already owned.\n\n#![unstable = \"recently added as part of collections reform\"]\n\nuse clone::Clone;\nuse kinds::Sized;\nuse ops::Deref;\nuse self::Cow::*;\n\n\/\/\/ A trait for borrowing data.\npub trait BorrowFrom<Sized?

The traits in this module provide a general way to talk about conversions\n\/\/! from one type to another. They follow the standard Rust conventions of\n\/\/! `as`\/`into`\/`from`.\n\/\/!\n\/\/! Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Impl the `As*` traits for reference-to-reference conversions\n\/\/! - Impl the `Into` trait when you want to consume the value in the conversion\n\/\/! - The `From` trait is the most flexible, useful for value _and_ reference conversions\n\/\/! - The `TryFrom` and `TryInto` traits behave like `From` and `Into`, but allow for the\n\/\/!   conversion to fail\n\/\/!\n\/\/! As a library author, you should prefer implementing `From<T>` or `TryFrom<T>` rather than\n\/\/! `Into<U>` or `TryInto<U>`, as `From` and `TryFrom` provide greater flexibility and offer\n\/\/! equivalent `Into` or `TryInto` implementations for free, thanks to a blanket implementation\n\/\/! in the standard library.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - `AsRef` and `AsMut` auto-dereference if the inner type is a reference\n\/\/! - `From<U> for T` implies `Into<T> for U`\n\/\/! - `TryFrom<U> for T` implies `TryInto<T> for U`\n\/\/! - `From` and `Into` are reflexive, which means that all types can `into()`\n\/\/!   themselves and `from()` themselves\n\/\/!\n\/\/!

The traits in this module provide a general way to talk about conversions\n\/\/! from one type to another. They follow the standard Rust conventions of\n\/\/! `as`\/`into`\/`from`.\n\/\/!\n\/\/! Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Impl the `As*` traits for reference-to-reference conversions\n\/\/! - Impl the `Into` trait when you want to consume the value in the conversion\n\/\/! - The `From` trait is the most flexible, useful for value _and_ reference conversions\n\/\/! - The `TryFrom` and `TryInto` traits behave like `From` and `Into`, but allow for the\n\/\/!   conversion to fail\n\/\/!\n\/\/! As a library author, you should prefer implementing `From<T>` or `TryFrom<T>` rather than\n\/\/! `Into<U>` or `TryInto<U>`, as `From` and `TryFrom` provide greater flexibility and offer\n\/\/! equivalent `Into` or `TryInto` implementations for free, thanks to a blanket implementation\n\/\/! in the standard library.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - `AsRef` and `AsMut` auto-dereference if the inner type is a reference\n\/\/! - `From<U> for T` implies `Into<T> for U`\n\/\/! - `TryFrom<U> for T` implies `TryInto<T> for U`\n\/\/! - `From` and `Into` are reflexive, which means that all types can `into()`\n\/\/!   themselves and `from()` themselves\n\/\/!\n\/\/!

This library is an implementation of futures in Rust which aims to provide\n\/\/! a robust implementation of handling asynchronous computations, ergonomic\n\/\/! composition and usage, and zero-cost abstractions over what would otherwise\n\/\/! be written by hand.\n\/\/!\n\/\/! Futures are a concept for an object which is a proxy for another value that\n\/\/! may not be ready yet. For example issuing an HTTP request may return a\n\/\/! future for the HTTP response, as it probably hasn't arrived yet. With an\n\/\/! object representing a value that will eventually be available, futures allow\n\/\/! for powerful composition of tasks through basic combinators that can perform\n\/\/! operations like chaining computations, changing the types of futures, or\n\/\/! waiting for two futures to complete at the same time.\n\/\/!\n\/\/! ## Installation\n\/\/!\n\/\/!

{"text":"<commit_before>\/\/! Zero-cost Futures in Rust\n\/\/!\n\/\/! This library is an implementation of futures in Rust which aims to provide\n\/\/! a robust implementation of handling asynchronous computations, ergonomic\n\/\/! composition and usage, and zero-cost abstractions over what would otherwise\n\/\/! be written by hand.\n\/\/!\n\/\/! Futures are a concept for an object which is a proxy for another value that\n\/\/! may not be ready yet. For example issuing an HTTP request may return a\n\/\/! future for the HTTP response, as it probably hasn't arrived yet. With an\n\/\/! object representing a value that will eventually be available, futures allow\n\/\/! for powerful composition of tasks through basic combinators that can perform\n\/\/! operations like chaining computations, changing the types of futures, or\n\/\/! waiting for two futures to complete at the same time.\n\/\/!\n\/\/! ## Installation\n\/\/!\n\/\/! Add this to your `Cargo.toml`:\n\/\/!\n\/\/! ```toml\n\/\/! [dependencies]\n\/\/! futures = \"0.1\"\n\/\/! ```\n\/\/!\n\/\/! ## Examples\n\/\/!\n\/\/!

That impl conflicts\n\/\/ with existing impls - at least the `impl<T> From<T> for T` impl. There are\n\/\/ 2 ways we thought of for dealing with that conflict:\n\/\/\n\/\/ 1. Using specialization and doing some handling for the overlap. The current\n\/\/ thought is for something like \"lattice specialization\", which means providing\n\/\/ an (higher-priority) impl for the intersection of every 2 conflicting impls\n\/\/ that determines what happens in the intersection case. That's the first\n\/\/ thing we thought about - see e.g.\n\/\/ https:\/\/github.com\/rust-lang\/rust\/issues\/57012#issuecomment-452150775\n\/\/\n\/\/ 2. The other way is to notice that `impl From<!> for T` is basically a marker\n\/\/ trait, as you say since its only method is uninhabited, and allow for \"marker\n\/\/ trait overlap\", where the conflict \"doesn't matter\" as there is nothing that\n\/\/ can cause a conflict.\n\/\/\n\/\/ Now it turned out lattice specialization doesn't work it, because an\n\/\/ `impl<T> From<T> for Smaht<T>` would require a `impl From<!> for Smaht<!>`,\n\/\/ breaking backwards-compatibility in a fairly painful way. So if we want to\n\/\/ go with a known approach, we should go with a \"marker trait overlap\"-style\n\/\/ approach.\n\n#![feature(rustc_attrs, never_type)]\n\ntrait MyTrait {}\n\nimpl MyTrait for ! {}\n\ntrait MyFrom<T> {\n    fn my_from(x: T) -> Self;\n}\n\n\/\/ Given the \"normal\" impls for From\n#[rustc_reservation_impl=\"this impl is reserved\"]\nimpl<T> MyFrom<!> for T {\n    fn my_from(x: !) -> Self { match x {} }\n}\n\nimpl<T> MyFrom<T> for T {\n    fn my_from(x: T) -> Self { x }\n}\n\n\/\/ ... we *do* want to allow this common pattern, of `From<!> for MySmaht<T>`\nstruct MySmaht<T>(T);\nimpl<T> MyFrom<T> for MySmaht<T> {\n    fn my_from(x: T) -> Self { MySmaht(x) }\n}\n\nfn main() {}\n<|endoftext|>"}

This module implements the `Any` trait, which enables dynamic typing\n\/\/! of any `'static` type through runtime reflection.\n\/\/!\n\/\/! `Any` itself can be used to get a `TypeId`, and has more features when used\n\/\/! as a trait object. As `&Any` (a borrowed trait object), it has the `is` and\n\/\/! `downcast_ref` methods, to test if the contained value is of a given type,\n\/\/! and to get a reference to the inner value as a type. As `&mut Any`, there\n\/\/! is also the `downcast_mut` method, for getting a mutable reference to the\n\/\/! inner value. `Box<Any>` adds the `downcast` method, which attempts to\n\/\/! convert to a `Box<T>`. See the [`Box`] documentation for the full details.\n\/\/!\n\/\/! Note that &Any is limited to testing whether a value is of a specified\n\/\/! concrete type, and cannot be used to test whether a type implements a trait.\n\/\/!\n\/\/!

This module implements the `Any` trait, which enables dynamic typing\n\/\/! of any `'static` type through runtime reflection.\n\/\/!\n\/\/! `Any` itself can be used to get a `TypeId`, and has more features when used\n\/\/! as a trait object. As `&Any` (a borrowed trait object), it has the `is` and\n\/\/! `downcast_ref` methods, to test if the contained value is of a given type,\n\/\/! and to get a reference to the inner value as a type. As `&mut Any`, there\n\/\/! is also the `downcast_mut` method, for getting a mutable reference to the\n\/\/! inner value. `Box<Any>` adds the `downcast` method, which attempts to\n\/\/! convert to a `Box<T>`. See the [`Box`] documentation for the full details.\n\/\/!\n\/\/! Note that &Any is limited to testing whether a value is of a specified\n\/\/! concrete type, and cannot be used to test whether a type implements a trait.\n\/\/!\n\/\/!

This mdoule defines types which are thread safe if cfg!(parallel_queries) is true.\n\/\/!\n\/\/! `Lrc` is an alias of either Rc or Arc.\n\/\/!\n\/\/! `Lock` is a mutex.\n\/\/! It internally uses `parking_lot::Mutex` if cfg!(parallel_queries) is true,\n\/\/! `RefCell` otherwise.\n\/\/!\n\/\/! `RwLock` is a read-write lock.\n\/\/! It internally uses `parking_lot::RwLock` if cfg!(parallel_queries) is true,\n\/\/! `RefCell` otherwise.\n\/\/!\n\/\/! `LockCell` is a thread safe version of `Cell`, with `set` and `get` operations.\n\/\/! It can never deadlock. It uses `Cell` when\n\/\/! cfg!(parallel_queries) is false, otherwise it is a `Lock`.\n\/\/!\n\/\/! `MTLock` is a mutex which disappears if cfg!(parallel_queries) is false.\n\/\/!\n\/\/! `rustc_global!` gives us a way to declare variables which are intended to be\n\/\/! global for the current rustc session. This currently maps to thread-locals,\n\/\/! since rustdoc uses the rustc libraries in multiple threads.\n\/\/! These globals should eventually be moved into the `Session` structure.\n\/\/!\n\/\/! `rustc_erase_owner!` erases a OwningRef owner into Erased or Erased + Send + Sync\n\/\/! depending on the value of cfg!(parallel_queries).\n\nuse std::cmp::Ordering;\nuse std::fmt::Debug;\nuse std::fmt::Formatter;\nuse std::fmt;\nuse owning_ref::{Erased, OwningRef};\n\ncfg_if!

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`kinds`](kinds\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an\n\/\/! array, lives in the [`vec`](vec\/index.html) module. References to\n\/\/! arrays, `&[T]`, more commonly called \"slices\", are built-in types\n\/\/! for which the [`slice`](slice\/index.html) module defines many\n\/\/! methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](from_str\/index.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`task`](task\/index.html) module contains Rust's threading abstractions,\n\/\/! while [`comm`](comm\/index.html) contains the channel types for message\n\/\/! passing. [`sync`](sync\/index.html) contains further, primitive, shared\n\/\/! memory types, including [`atomics`](sync\/atomics\/index.html).\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the [`io`](io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\n#![crate_name = \"std\"]\n#![unstable]\n#![comment = \"The Rust standard library\"]\n#![license = \"MIT\/ASL2\"]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n       html_root_url = \"http:\/\/doc.rust-lang.org\/nightly\/\",\n       html_playground_url = \"http:\/\/play.rust-lang.org\/\")]\n\n#![allow(unknown_features)]\n#![feature(macro_rules, globs, linkage)]\n#![feature(default_type_params, phase, lang_items, unsafe_destructor)]\n#![feature(import_shadowing, slicing_syntax)]\n\n\/\/ Don't link to std.

It handles many of the things that most people just expect an HTTP client\n\/\/! to do for them.\n\/\/!\n\/\/! - Uses system-native TLS\n\/\/! - Plain bodies, JSON, urlencoded, (TODO: multipart)\n\/\/! - (TODO: Customizable redirect policy)\n\/\/! - (TODO: Cookies)\n\/\/!\n\/\/! The `reqwest::Client` is synchronous, making it a great fit for\n\/\/! applications that only require a few HTTP requests, and wish to handle\n\/\/! them synchronously. When [hyper][] releases with asynchronous support,\n\/\/! `reqwest` will be updated to use it internally, but still provide a\n\/\/! synchronous Client, for convenience. A `reqwest::async::Client` will also\n\/\/! be added.\n\/\/!\n\/\/! ## Making a GET request\n\/\/!\n\/\/! For a single request, you can use the `get` shortcut method.\n\/\/!\n\/\/!\n\/\/! ```no_run\n\/\/! let resp = reqwest::get(\"https:\/\/www.rust-lang.org\").unwrap();\n\/\/! assert!(resp.status().is_success());\n\/\/! ```\n\/\/!\n\/\/! If you plan to perform multiple requests, it is best to create a [`Client`][client]\n\/\/! and reuse it, taking advantage of keep-alive connection pooling.\n\/\/!\n\/\/! ## Making POST requests (or setting request bodies)\n\/\/!\n\/\/! There are several ways you can set the body of a request. The basic one is\n\/\/! by using the `body()` method of a [`RequestBuilder`][builder]. This lets you set the\n\/\/! exact raw bytes of what the body should be. It accepts various types,\n\/\/! including `String`, `Vec<u8>`, and `File`. If you wish to pass a custom\n\/\/! Reader, you can use the `reqwest::Body::new()` constructor.\n\/\/!\n\/\/! ```no_run\n\/\/! let client = reqwest::Client::new().unwrap();\n\/\/! let res = client.post(\"http:\/\/httpbin.org\/post\")\n\/\/!     .body(\"the exact body that is sent\")\n\/\/!     .send();\n\/\/! ```\n\/\/!\n\/\/! ### Forms\n\/\/!\n\/\/! It's very common to want to send form data in a request body. This can be\n\/\/! done with any type that can be serialized into form data.\n\/\/!\n\/\/! This can be an array of tuples, or a `HashMap`, or a custom type that\n\/\/! implements [`Serialize`][serde].\n\/\/!\n\/\/! ```no_run\n\/\/! \/\/ This will POST a body of `foo=bar&baz=quux`\n\/\/! let params = [(\"foo\", \"bar\"), (\"baz\", \"quux\")];\n\/\/! let client = reqwest::Client::new().unwrap();\n\/\/! let res = client.post(\"http:\/\/httpbin.org\/post\")\n\/\/!     .form(&params)\n\/\/!     .send();\n\/\/! ```\n\/\/!\n\/\/! ### JSON\n\/\/!\n\/\/! There is also a `json` method helper on the [`RequestBuilder`][builder] that works in\n\/\/! a similar fashion the `form` method.

It's most commonly seen when attempting to\nreturn a closure:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be unsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable. For example:\n\n```\nfn main() {\n    let x: i32;\n    let y = x; \/\/ error, use of possibly uninitialized variable\n```\n\nTo fix this, ensure that any declared variables are initialized before being\nused.\n\"##,\n\nE0382: r##\"\nThis error occurs when an attempt is made to use a variable after its contents\nhave been moved elsewhere. For example:\n\n```\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nSince `MyStruct` is a type that is not marked `Copy`, the data gets moved out\nof `x` when we set `y`. This is fundamental to Rust's ownership system: outside\nof workarounds like `Rc`, a value cannot be owned by more than one variable.\n\nIf we own the type, the easiest way to address this problem is to implement\n`Copy` and `Clone` on it, as shown below. This allows `y` to copy the\ninformation in `x`, while leaving the original version owned by `x`. Subsequent\nchanges to `x` will not be reflected when accessing `y`.\n\n```\n#[derive(Copy, Clone)]\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nAlternatively, if we don't control the struct's definition, or mutable shared\nownership is truly required, we can use `Rc` and `RefCell`:\n\n```\nuse std::cell::RefCell;\nuse std::rc::Rc;\n\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = Rc::new(RefCell::new(MyStruct{ s: 5u32 }));\n    let y = x.clone();\n    x.borrow_mut().s = 6;\n    println!(\"{}\", x.borrow.s);\n}\n```\n\nWith this approach, x and y share ownership of the data via the `Rc` (reference\ncount type). `RefCell` essentially performs runtime borrow checking: ensuring\nthat at most one writer or multiple readers can access the data at any one time.\n\nIf you wish to learn more about ownership in Rust, start with the chapter in the\nBook:\n\nhttps:\/\/doc.rust-lang.org\/book\/ownership.html\n\"##,\n\nE0383: r##\"\nThis error occurs when an attempt is made to partially reinitialize a\nstructure that is currently uninitialized.\n\nFor example, this can happen when a drop has taken place:\n\n```\nlet mut x = Foo { a: 1 };\ndrop(x); \/\/ `x` is now uninitialized\nx.a = 2; \/\/ error, partial reinitialization of uninitialized structure `t`\n```\n\nThis error can be fixed by fully reinitializing the structure in question:\n\n```\nlet mut x = Foo { a: 1 };\ndrop(x);\nx = Foo { a: 2 };\n```\n\"##,\n\nE0384: r##\"\nThis error occurs when an attempt is made to reassign an immutable variable.\nFor example:\n\n```\nfn main(){\n    let x = 3;\n    x = 5; \/\/ error, reassignment of immutable variable\n}\n```\n\nBy default, variables in Rust are immutable. To fix this error, add the keyword\n`mut` after the keyword `let` when declaring the variable. For example:\n\n```\nfn main(){\n    let mut x = 3;\n    x = 5;\n}\n```\n\"##,\n\nE0386: r##\"\nThis error occurs when an attempt is made to mutate the target of a mutable\nreference stored inside an immutable container.\n\nFor example, this can happen when storing a `&mut` inside an immutable `Box`:\n\n```\nlet mut x: i64 = 1;\nlet y: Box<_> = Box::new(&mut x);\n**y = 2; \/\/ error, cannot assign to data in an immutable container\n```\n\nThis error can be fixed by making the container mutable:\n\n```\nlet mut x: i64 = 1;\nlet mut y: Box<_> = Box::new(&mut x);\n**y = 2;\n```\n\nIt can also be fixed by using a type with interior mutability, such as `Cell` or\n`RefCell`:\n\n```\nlet x: i64 = 1;\nlet y: Box<Cell<_>> = Box::new(Cell::new(x));\ny.set(2);\n```\n\"##,\n\nE0387: r##\"\nThis error occurs when an attempt is made to mutate or mutably reference data\nthat a closure has captured immutably. Examples of this error are shown below:\n\n```\n\/\/ Accepts a function or a closure that captures its environment immutably.\n\/\/ Closures passed to foo will not be able to mutate their closed-over state.\nfn foo<F: Fn()>(f: F) { }\n\n\/\/ Attempts to mutate closed-over data.  Error message reads:\n\/\/ `cannot assign to data in a captured outer variable...`\nfn mutable() {\n    let mut x = 0u32;\n    foo(|| x = 2);\n}\n\n\/\/ Attempts to take a mutable reference to closed-over data.  Error message\n\/\/ reads: `cannot borrow data mutably in a captured outer variable...`\nfn mut_addr() {\n    let mut x = 0u32;\n    foo(|| { let y = &mut x; });\n}\n```\n\nThe problem here is that foo is defined as accepting a parameter of type `Fn`.\nClosures passed into foo will thus be inferred to be of type `Fn`, meaning that\nthey capture their context immutably.\n\nIf the definition of `foo` is under your control, the simplest solution is to\ncapture the data mutably. This can be done by defining `foo` to take FnMut\nrather than Fn:\n\n```\nfn foo<F: FnMut()>(f: F) { }\n```\n\nAlternatively, we can consider using the `Cell` and `RefCell` types to achieve\ninterior mutability through a shared reference. Our example's `mutable` function\ncould be redefined as below:\n\n```\nuse std::cell::Cell;\n\nfn mutable() {\n    let x = Cell::new(0u32);\n    foo(|| x.set(2));\n}\n```\n\nYou can read more about cell types in the API documentation:\n\nhttps:\/\/doc.rust-lang.org\/std\/cell\/\n\"##,\n\nE0499: r##\"\nA variable was borrowed as mutable more than once. Erroneous code example:\n\n```\nlet mut i = 0;\nlet mut x = &mut i;\nlet mut a = &mut i;\n\/\/ error: cannot borrow `i` as mutable more than once at a time\n```\n\nPlease note that in rust, you can either have many immutable references, or one\nmutable reference. Take a look at\nhttps:\/\/doc.rust-lang.org\/stable\/book\/references-and-borrowing.html for more\ninformation.

It's most commonly seen when attempting to\nreturn a closure:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be unsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable. For example:\n\n```\nfn main() {\n    let x: i32;\n    let y = x; \/\/ error, use of possibly uninitialized variable\n```\n\nTo fix this, ensure that any declared variables are initialized before being\nused.\n\"##,\n\nE0382: r##\"\nThis error occurs when an attempt is made to use a variable after its contents\nhave been moved elsewhere. For example:\n\n```\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nSince `MyStruct` is a type that is not marked `Copy`, the data gets moved out\nof `x` when we set `y`. This is fundamental to Rust's ownership system: outside\nof workarounds like `Rc`, a value cannot be owned by more than one variable.\n\nIf we own the type, the easiest way to address this problem is to implement\n`Copy` and `Clone` on it, as shown below. This allows `y` to copy the\ninformation in `x`, while leaving the original version owned by `x`. Subsequent\nchanges to `x` will not be reflected when accessing `y`.\n\n```\n#[derive(Copy, Clone)]\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nAlternatively, if we don't control the struct's definition, or mutable shared\nownership is truly required, we can use `Rc` and `RefCell`:\n\n```\nuse std::cell::RefCell;\nuse std::rc::Rc;\n\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = Rc::new(RefCell::new(MyStruct{ s: 5u32 }));\n    let y = x.clone();\n    x.borrow_mut().s = 6;\n    println!(\"{}\", x.borrow().s);\n}\n```\n\nWith this approach, x and y share ownership of the data via the `Rc` (reference\ncount type). `RefCell` essentially performs runtime borrow checking: ensuring\nthat at most one writer or multiple readers can access the data at any one time.\n\nIf you wish to learn more about ownership in Rust, start with the chapter in the\nBook:\n\nhttps:\/\/doc.rust-lang.org\/book\/ownership.html\n\"##,\n\nE0383: r##\"\nThis error occurs when an attempt is made to partially reinitialize a\nstructure that is currently uninitialized.\n\nFor example, this can happen when a drop has taken place:\n\n```\nlet mut x = Foo { a: 1 };\ndrop(x); \/\/ `x` is now uninitialized\nx.a = 2; \/\/ error, partial reinitialization of uninitialized structure `t`\n```\n\nThis error can be fixed by fully reinitializing the structure in question:\n\n```\nlet mut x = Foo { a: 1 };\ndrop(x);\nx = Foo { a: 2 };\n```\n\"##,\n\nE0384: r##\"\nThis error occurs when an attempt is made to reassign an immutable variable.\nFor example:\n\n```\nfn main(){\n    let x = 3;\n    x = 5; \/\/ error, reassignment of immutable variable\n}\n```\n\nBy default, variables in Rust are immutable. To fix this error, add the keyword\n`mut` after the keyword `let` when declaring the variable. For example:\n\n```\nfn main(){\n    let mut x = 3;\n    x = 5;\n}\n```\n\"##,\n\nE0386: r##\"\nThis error occurs when an attempt is made to mutate the target of a mutable\nreference stored inside an immutable container.\n\nFor example, this can happen when storing a `&mut` inside an immutable `Box`:\n\n```\nlet mut x: i64 = 1;\nlet y: Box<_> = Box::new(&mut x);\n**y = 2; \/\/ error, cannot assign to data in an immutable container\n```\n\nThis error can be fixed by making the container mutable:\n\n```\nlet mut x: i64 = 1;\nlet mut y: Box<_> = Box::new(&mut x);\n**y = 2;\n```\n\nIt can also be fixed by using a type with interior mutability, such as `Cell` or\n`RefCell`:\n\n```\nlet x: i64 = 1;\nlet y: Box<Cell<_>> = Box::new(Cell::new(x));\ny.set(2);\n```\n\"##,\n\nE0387: r##\"\nThis error occurs when an attempt is made to mutate or mutably reference data\nthat a closure has captured immutably. Examples of this error are shown below:\n\n```\n\/\/ Accepts a function or a closure that captures its environment immutably.\n\/\/ Closures passed to foo will not be able to mutate their closed-over state.\nfn foo<F: Fn()>(f: F) { }\n\n\/\/ Attempts to mutate closed-over data.  Error message reads:\n\/\/ `cannot assign to data in a captured outer variable...`\nfn mutable() {\n    let mut x = 0u32;\n    foo(|| x = 2);\n}\n\n\/\/ Attempts to take a mutable reference to closed-over data.  Error message\n\/\/ reads: `cannot borrow data mutably in a captured outer variable...`\nfn mut_addr() {\n    let mut x = 0u32;\n    foo(|| { let y = &mut x; });\n}\n```\n\nThe problem here is that foo is defined as accepting a parameter of type `Fn`.\nClosures passed into foo will thus be inferred to be of type `Fn`, meaning that\nthey capture their context immutably.\n\nIf the definition of `foo` is under your control, the simplest solution is to\ncapture the data mutably. This can be done by defining `foo` to take FnMut\nrather than Fn:\n\n```\nfn foo<F: FnMut()>(f: F) { }\n```\n\nAlternatively, we can consider using the `Cell` and `RefCell` types to achieve\ninterior mutability through a shared reference. Our example's `mutable` function\ncould be redefined as below:\n\n```\nuse std::cell::Cell;\n\nfn mutable() {\n    let x = Cell::new(0u32);\n    foo(|| x.set(2));\n}\n```\n\nYou can read more about cell types in the API documentation:\n\nhttps:\/\/doc.rust-lang.org\/std\/cell\/\n\"##,\n\nE0499: r##\"\nA variable was borrowed as mutable more than once. Erroneous code example:\n\n```\nlet mut i = 0;\nlet mut x = &mut i;\nlet mut a = &mut i;\n\/\/ error: cannot borrow `i` as mutable more than once at a time\n```\n\nPlease note that in rust, you can either have many immutable references, or one\nmutable reference. Take a look at\nhttps:\/\/doc.rust-lang.org\/stable\/book\/references-and-borrowing.html for more\ninformation. Example:\n\n\n```\nlet mut i = 0;\nlet mut x = &mut i; \/\/ ok!\n\n\/\/ or:\nlet mut i = 0;\nlet a = &i; \/\/ ok!\nlet b = &i; \/\/ still ok!\nlet c = &i; \/\/ still ok!\n```\n\"##,\n\nE0507: r##\"\nYou tried to move out of a value which was borrowed.

Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in two major\nphases: collect and check.  The collect phase passes over all items and\ndetermines their type, without examining their \"innards\".  The check phase\nthen checks function bodies and so forth.\n\nWithin the check phase, we check each function body one at a time (bodies of\nfunction expressions are checked as part of the containing function).\nInference is used to supply types wherever they are unknown. The actual\nchecking of a function itself has several phases (check, regionck, writeback),\nas discussed in the documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n*\/\n\nimport result::{result, extensions};\nimport syntax::{ast, ast_util, ast_map};\nimport

Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in two major\nphases: collect and check.  The collect phase passes over all items and\ndetermines their type, without examining their \"innards\".  The check phase\nthen checks function bodies and so forth.\n\nWithin the check phase, we check each function body one at a time (bodies of\nfunction expressions are checked as part of the containing function).\nInference is used to supply types wherever they are unknown. The actual\nchecking of a function itself has several phases (check, regionck, writeback),\nas discussed in the documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n*\/\n\nimport result::{result, extensions};\nimport syntax::{ast, ast_util, ast_map};\nimport

{"text":"<commit_before>\/\/! # Mime\n\/\/!\n\/\/! Mime is now Media Type, technically, but `Mime` is more immediately\n\/\/! understandable, so the main type here is `Mime`.\n\/\/!\n\/\/! ## What is Mime?\n\/\/!\n\/\/! Example mime string: `text\/plain;charset=utf-8`\n\/\/!\n\/\/! ```rust\n\/\/! # #[macro_use] extern crate mime;\n\/\/! # fn main() {\n\/\/! let plain_text: mime::Mime = \"text\/plain;charset=utf-8\".parse().unwrap();\n\/\/! assert_eq!(plain_text, mime!(Text\/Plain; Charset=Utf8));\n\/\/! # }\n\/\/! ```\n\n#![doc(html_root_url = \"https:\/\/hyperium.github.io\/mime.rs\")]\n#![cfg_attr(test, deny(warnings))]\n#![cfg_attr(all(feature = \"nightly\", test), feature(test))]\n\n#[macro_use]\nextern crate log;\n\n#[cfg(feature = \"nightly\")]\n#[cfg(test)]\nextern crate test;\n\nuse std::ascii::AsciiExt;\nuse std::fmt;\nuse std::iter::Enumerate;\nuse std::str::{FromStr, Chars};\n\nmacro_rules! inspect(\n    ($s:expr, $t:expr) => ({\n        let t = $t;\n        trace!(\"inspect {}: {:?}\", $s, t);\n        t\n    })\n);\n\n\/\/\/ Mime, or Media Type. Encapsulates common registers types.\n\/\/\/\n\/\/\/ Consider that a traditional mime type contains a \"top level type\",\n\/\/\/ a \"sub level type\", and 0-N \"parameters\". And they're all strings.\n\/\/\/ Strings everywhere. Strings mean typos. Rust has type safety. We should\n\/\/\/ use types!\n\/\/\/\n\/\/\/ So, Mime bundles together this data into types so the compiler can catch\n\/\/\/ your typos.\n\/\/\/\n\/\/\/ This improves things so you use match without Strings:\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ use mime::{Mime, TopLevel, SubLevel};\n\/\/\/\n\/\/\/ let mime: Mime = \"application\/json\".parse().unwrap();\n\/\/\/\n\/\/\/ match mime {\n\/\/\/     Mime(TopLevel::Application, SubLevel::Json, _) => println!(\"matched json!\"),\n\/\/\/     _ => ()\n\/\/\/ }\n\/\/\/ ```\n#[derive(Clone, Debug)]\npub struct Mime<T: AsRef<[Param]> = Vec<Param>>(pub TopLevel, pub SubLevel, pub T);\n\nimpl<LHS: AsRef<[Param]>, RHS: AsRef<[Param]>> PartialEq<Mime<RHS>> for Mime<LHS> {\n    fn eq(&self, other: &Mime<RHS>) -> bool {\n        self.0 == other.0 && self.1 == other.1 && self.2.as_ref() == other.2.as_ref()\n    }\n}\n\n\/\/\/ Easily create a Mime without having to import so many enums.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ #

Mime is now Media Type, technically, but `Mime` is more immediately\n\/\/! understandable, so the main type here is `Mime`.\n\/\/!\n\/\/! ## What is Mime?\n\/\/!\n\/\/! Example mime string: `text\/plain;charset=utf-8`\n\/\/!\n\/\/! ```rust\n\/\/! # #[macro_use] extern crate mime;\n\/\/! # fn main() {\n\/\/! let plain_text: mime::Mime = \"text\/plain;charset=utf-8\".parse().unwrap();\n\/\/! assert_eq!(plain_text, mime!(Text\/Plain; Charset=Utf8));\n\/\/! # }\n\/\/! ```\n\n#![doc(html_root_url = \"https:\/\/hyperium.github.io\/mime.rs\")]\n#![cfg_attr(test, deny(warnings))]\n#![cfg_attr(all(feature = \"nightly\", test), feature(test))]\n\n#[macro_use]\nextern crate log;\n\n#[cfg(feature = \"nightly\")]\n#[cfg(test)]\nextern crate test;\n\nuse std::ascii::AsciiExt;\nuse std::fmt;\nuse std::iter::Enumerate;\nuse std::str::{FromStr, Chars};\n\nmacro_rules! inspect(\n    ($s:expr, $t:expr) => ({\n        let t = $t;\n        trace!(\"inspect {}: {:?}\", $s, t);\n        t\n    })\n);\n\n\/\/\/ Mime, or Media Type. Encapsulates common registers types.\n\/\/\/\n\/\/\/ Consider that a traditional mime type contains a \"top level type\",\n\/\/\/ a \"sub level type\", and 0-N \"parameters\". And they're all strings.\n\/\/\/ Strings everywhere. Strings mean typos. Rust has type safety. We should\n\/\/\/ use types!\n\/\/\/\n\/\/\/ So, Mime bundles together this data into types so the compiler can catch\n\/\/\/ your typos.\n\/\/\/\n\/\/\/ This improves things so you use match without Strings:\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ use mime::{Mime, TopLevel, SubLevel};\n\/\/\/\n\/\/\/ let mime: Mime = \"application\/json\".parse().unwrap();\n\/\/\/\n\/\/\/ match mime {\n\/\/\/     Mime(TopLevel::Application, SubLevel::Json, _) => println!(\"matched json!\"),\n\/\/\/     _ => ()\n\/\/\/ }\n\/\/\/ ```\n#[derive(Clone, Debug)]\npub struct Mime<T: AsRef<[Param]> = Vec<Param>>(pub

It is an error to have a newtype body field and\n\/\/\/ normal body fields within the same struct.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```rust,ignore\n\/\/\/ pub mod some_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: GET,\n\/\/\/             name: \"some_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/endpoint\/:baz\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             pub foo: String,\n\/\/\/\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             #[ruma_api(query)]\n\/\/\/             pub bar: String,\n\/\/\/\n\/\/\/             #[ruma_api(path)]\n\/\/\/             pub baz: String,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             pub value: String,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/\n\/\/\/ pub mod newtype_body_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/\n\/\/\/     #[derive(Clone, Debug, Deserialize, Serialize)]\n\/\/\/     pub struct MyCustomType {\n\/\/\/         pub foo: String,\n\/\/\/     }\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: GET,\n\/\/\/             name: \"newtype_body_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/newtype\/body\/endpoint\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             #[ruma_api(body)]\n\/\/\/             pub file: Vec<u8>,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(body)]\n\/\/\/             pub my_custom_type: MyCustomType,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n#[proc_macro]\npub fn ruma_api(input: TokenStream) -> TokenStream {\n    let raw_api = syn::parse_macro_input!(input as RawApi);\n\n    let api = Api::from(raw_api);\n\n    api.into_token_stream().into()\n}\n<|endoftext|>"}

The first time `next()` is called,\n\/\/\/ the function is called as `f(yielder)`; every time `next()` is called afterwards,\n\/\/\/ the function is resumed. In either case, it runs until it suspends its execution\n\/\/\/ through `yielder.generate(val)`), in which case `next()` returns `Some(val)`, or\n\/\/\/ returns, in which case `next()` returns `None`. `next()` will return `None`\n\/\/\/ every time after that.\n\/\/\/\n\/\/\/ After the generator function returns, it is safe to reclaim the generator\n\/\/\/ stack using `unwrap()`.\n\/\/\/\n\/\/\/ `state()` can be used to determine whether the generator function has returned;\n\/\/\/ the state is `State::Suspended` after creation and suspension, and `State::Finished`\n\/\/\/ once the generator function returns.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ use fringe::{OsStack, Generator};\n\/\/\/\n\/\/\/ let stack = OsStack::new(0).unwrap();\n\/\/\/ let mut gen = Generator::new(stack, move |yielder| {\n\/\/\/   for i in 1..4 {\n\/\/\/     yielder.generate(i);\n\/\/\/   }\n\/\/\/ });\n\/\/\/ println!(\"{:?}\", gen.next()); \/\/ prints Some(1)\n\/\/\/ println!(\"{:?}\", gen.next()); \/\/ prints Some(2)\n\/\/\/ println!(\"{:?}\", gen.next()); \/\/ prints Some(3)\n\/\/\/ println!(\"{:?}\", gen.next()); \/\/ prints None\n\/\/\/ ```\n#[derive(Debug)]\npub struct Generator<Item: Send, Stack: stack::Stack> {\n  state:   State,\n  context: context::Context<Stack>,\n  phantom: PhantomData<Item>\n}\n\nimpl<Item, Stack> Generator<Item, Stack>\n    where Item: Send, Stack: stack::Stack {\n  \/\/\/ Creates a new generator.\n  pub fn new<F>(stack: Stack, f: F) -> Generator<Item, Stack>\n      where Stack: stack::GuardedStack, F: FnOnce(&mut Yielder<Item, Stack>) + Send {\n    unsafe { Generator::unsafe_new(stack, f) }\n  }\n\n  \/\/\/ Same as `new`, but does not require `stack` to have a guard page.\n  \/\/\/\n  \/\/\/ This function is unsafe because the generator function can easily violate\n  \/\/\/ memory safety by overflowing the stack.

For example if\n\/\/ you have some concurrent futures working, they may all want mutable access to\n\/\/ some data. We already know that when the futures are being poll'd that we're\n\/\/ entirely synchronized (aka `&mut Task`), so you shouldn't require an\n\/\/ `Arc<Mutex<T>>` to share as the synchronization isn't necessary!\n\/\/\n\/\/ So the idea here is that you insert data into a task via `Task::insert`, and\n\/\/ a handle to that data is then returned to you. That handle can later get\n\/\/ presented to the task itself to actually retrieve the underlying data. The\n\/\/ invariant is that the data can only ever be accessed with the task present,\n\/\/ and the lifetime of the actual data returned is connected to the lifetime of\n\/\/ the task itself.\n\/\/\n\/\/ Conceptually I at least like to think of this as \"dynamically adding more\n\/\/ struct fields to a `Task`\". Each call to insert creates a new \"name\" for the\n\/\/ struct field, a `TaskData<A>`, and then you can access the fields of a struct\n\/\/ with the struct itself (`Task`) as well as the name of the field\n\/\/ (`TaskData<A>`). If that analogy doesn't make sense then oh well, it at least\n\/\/ helped me!\n\/\/\n\/\/ So anyway, we do some interesting trickery here to actually get it to work.\n\/\/ Each `TaskData<A>` handle stores `Arc<UnsafeCell<A>>`. So it turns out, we're\n\/\/ not even adding data to the `Task`! Each `TaskData<A>` contains a reference\n\/\/ to this `Arc`, and `TaskData` handles can be cloned which just bumps the\n\/\/ reference count on the `Arc` itself.\n\/\/\n\/\/ As before, though, you can present the `Arc` to a `Task` and if they\n\/\/ originated from the same place you're allowed safe access to the internals.\n\/\/ We allow but shared and mutable access without the `Sync` bound on the data,\n\/\/ crucially noting that a `Task` itself is not `Sync`.\n\/\/\n\/\/ So hopefully I've convinced you of this point that the `get` and `get_mut`\n\/\/ methods below are indeed safe. The data is always valid as it's stored in an\n\/\/ `Arc`, and access is only allowed with the proof of the associated `Task`.\n\/\/ One thing you might be asking yourself though is what exactly is this \"proof\n\/\/ of a task\"? Right now it's a `usize` corresponding to the `Task`'s\n\/\/ `TaskHandle` arc allocation.\n\/\/\n\/\/ Wait a minute, isn't that the ABA problem! That is, we create a task A, add\n\/\/ some data to it, destroy task A, do some work, create a task B, and then ask\n\/\/ to get the data from task B. In this case though the point of the\n\/\/ `task_inner` \"proof\" field is simply that there's some non-`Sync` token\n\/\/ proving that you can get access to the data.

However, any precise estimate depends on a partly arbitrary distinction between languages and dialects. Natural languages are spoken or signed, but any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, in graphic writing, braille, or whistling. This is because human language is modality-independent. Depending on philosophical perspectives regarding the definition of language and meaning, when used as a general concept, 'language' may refer to the cognitive ability to learn and use systems of complex communication, or to describe the set of rules that makes up these systems, or the set of utterances that can be produced from those rules. All languages rely on the process of semiosis to relate signs to particular meanings.

This file may not be\n\/\/ copied, modified, or distributed except according to those terms.\n\n\/\/ To understand the machine code in this file, keep in mind these facts:\n\/\/ * OR1K C ABI has a \"red zone\": 128 bytes under the top of the stack\n\/\/   that is defined to be unmolested by signal handlers, interrupts, etc.\n\/\/   Leaf functions can use the red zone without adjusting r1 or r2.\n\/\/ * OR1K C ABI passes the first argument in r3. We also use r3 to pass a value\n\/\/   while swapping context; this is an arbitrary choice\n\/\/   (we clobber all registers and could use any of them) but this allows us\n\/\/   to reuse the swap function to perform the initial call.\n\/\/\n\/\/ To understand the DWARF CFI code in this file, keep in mind these facts:\n\/\/ * CFI is \"call frame information\"; a set of instructions to a debugger or\n\/\/   an unwinder that allow it to simulate returning from functions. This implies\n\/\/   restoring every register to its pre-call state, as well as the stack pointer.\n\/\/ * CFA is \"call frame address\"; the value of stack pointer right before the call\n\/\/   instruction in the caller. Everything strictly below CFA (and inclusive until\n\/\/   the next CFA) is the call frame of the callee. This implies that the return\n\/\/   address is the part of callee's call frame.\n\/\/ * Logically, DWARF CFI is a table where rows are instruction pointer values and\n\/\/   columns describe where registers are spilled (mostly using expressions that\n\/\/   compute a memory location as CFA+n). A .cfi_offset pseudoinstruction changes\n\/\/   the state of a column for all IP numerically larger than the one it's placed\n\/\/   after. A .cfi_def_* pseudoinstruction changes the CFA value similarly.\n\/\/ * Simulating return is as easy as restoring register values from the CFI table\n\/\/   and then setting stack pointer to CFA.\n\/\/\n\/\/ A high-level overview of the function of the trampolines is:\n\/\/ * The 2nd init trampoline puts a controlled value (written in swap to `new_cfa`)\n\/\/   into r13.\n\/\/ * The 1st init trampoline tells the unwinder to set r1 to r13, thus continuing\n\/\/   unwinding at the swap call site instead of falling off the end of context stack.\n\/\/ * The 1st init trampoline together with the swap trampoline also restore r2\n\/\/   when unwinding as well as returning normally, because LLVM does not do it for us.\nuse stack::Stack;\n\n#[derive(Debug, Clone)]\npub struct StackPointer(*mut usize);\n\npub unsafe fn init(stack: &Stack, f: unsafe extern \"C\" fn(usize) -> !) -> StackPointer {\n  #[naked]\n  unsafe extern \"C\" fn trampoline_1() {\n    asm!(\n      r#\"\n        # gdb has a hardcoded check that rejects backtraces where frame addresses\n        # do not monotonically decrease.

We also use r3 to pass a value\n\/\/   while swapping context; this is an arbitrary choice\n\/\/   (we clobber all registers and could use any of them) but this allows us\n\/\/   to reuse the swap function to perform the initial call.\n\/\/\n\/\/ To understand the DWARF CFI code in this file, keep in mind these facts:\n\/\/ * CFI is \"call frame information\"; a set of instructions to a debugger or\n\/\/   an unwinder that allow it to simulate returning from functions. This implies\n\/\/   restoring every register to its pre-call state, as well as the stack pointer.\n\/\/ * CFA is \"call frame address\"; the value of stack pointer right before the call\n\/\/   instruction in the caller. Everything strictly below CFA (and inclusive until\n\/\/   the next CFA) is the call frame of the callee. This implies that the return\n\/\/   address is the part of callee's call frame.\n\/\/ * Logically, DWARF CFI is a table where rows are instruction pointer values and\n\/\/   columns describe where registers are spilled (mostly using expressions that\n\/\/   compute a memory location as CFA+n). A .cfi_offset pseudoinstruction changes\n\/\/   the state of a column for all IP numerically larger than the one it's placed\n\/\/   after. A .cfi_def_* pseudoinstruction changes the CFA value similarly.\n\/\/ * Simulating return is as easy as restoring register values from the CFI table\n\/\/   and then setting stack pointer to CFA.\n\/\/\n\/\/ A high-level overview of the function of the trampolines is:\n\/\/ * The 2nd init trampoline puts a controlled value (written in swap to `new_cfa`)\n\/\/   into r13.\n\/\/ * The 1st init trampoline tells the unwinder to set r1 to r13, thus continuing\n\/\/   unwinding at the swap call site instead of falling off the end of context stack.\n\/\/ * The 1st init trampoline together with the swap trampoline also restore r2\n\/\/   when unwinding as well as returning normally, because LLVM does not do it for us.\nuse stack::Stack;\n\n#[derive(Debug, Clone)]\npub struct StackPointer(*mut usize);\n\npub unsafe fn init(stack: &Stack, f: unsafe extern \"C\" fn(usize) -> !) -> StackPointer {\n  #[naked]\n  unsafe extern \"C\" fn trampoline_1() {\n    asm!(\n      r#\"\n        # gdb has a hardcoded check that rejects backtraces where frame addresses\n        # do not monotonically decrease.

Same as\n\/\/ above, we want to make sure that the change between rev1 and rev2 also\n\/\/ results in a change of the ICH for the struct's metadata, and that it stays\n\/\/ the same between rev2 and rev3.\n\n\/\/ must-compile-successfully\n\/\/ revisions: cfail1 cfail2 cfail3\n\/\/ compile-flags: -Z

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/!\n\/\/! The rust standard library is available to all rust crates by\n\/\/! default, just as if contained an `extern crate std` import at the\n\/\/! crate root. Therefore the standard library can be accessed in\n\/\/! `use` statements through the path `std`, as in `use std::thread`,\n\/\/! or in expressions through the absolute path `::std`, as in\n\/\/! `::std::thread::sleep_ms(100)`.\n\/\/!\n\/\/! Furthermore, the standard library defines [The Rust\n\/\/! Prelude](prelude\/index.html), a small collection of items, mostly\n\/\/! traits, that are imported into and available in every module.\n\/\/!\n\/\/! ## What is in the standard library\n\/\/!\n\/\/! The standard library is minimal, a set of battle-tested\n\/\/! core types and shared abstractions for the [broader Rust\n\/\/! ecosystem][https:\/\/crates.io] to build on.\n\/\/!\n\/\/! The [primitive types](#primitives), though not defined in the\n\/\/! standard library, are documented here, as are the predefined\n\/\/! [macros](#macros).\n\/\/!\n\/\/! ## Containers and collections\n\/\/!\n\/\/! The [`option`](option\/index.html) and\n\/\/! [`result`](result\/index.html) modules define optional and\n\/\/! error-handling types, `Option` and `Result`. The\n\/\/! [`iter`](iter\/index.html) module defines Rust's iterator trait,\n\/\/! [`Iterater`](iter\/trait.Iterator.html), which works with the `for`\n\/\/! loop to access collections.\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! Data may be shared by placing it in a reference-counted box or the\n\/\/! [`Rc`][rc\/index.html] type, and if further contained in a [`Cell`\n\/\/! or `RefCell`](cell\/index.html), may be mutated as well as shared.\n\/\/! Likewise, in a concurrent setting it is common to pair an\n\/\/! atomically-reference-counted box, [`Arc`](sync\/struct.Arc.html),\n\/\/! with a [`Mutex`](sync\/struct.Mutex.html) to get the same effect.\n\/\/!\n\/\/! The [`collections`](collections\/index.html) module defines maps,\n\/\/! sets, linked lists and other typical collection types, including\n\/\/! the common [`HashMap`](collections\/struct.HashMap.html).\n\/\/!\n\/\/! ## Platform abstractions and I\/O\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives.\n\/\/!\n\/\/! Common types of I\/O, including [files](fs\/struct.File.html),\n\/\/! [TCP](net\/struct.TcpStream.html),\n\/\/! [UDP](net\/struct.UdpSocket.html), are defined in the\n\/\/! [`io`](io\/index.html), [`fs`](fs\/index.html), and\n\/\/! [`net`](net\/index.html) modules.\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading\n\/\/! abstractions. [`sync`](sync\/index.html) contains further\n\/\/! primitive shared memory types, including\n\/\/! [`atomic`](sync\/atomic\/index.html) and\n\/\/! [`mpsc`](sync\/mpsc\/index.html), which contains the channel types\n\/\/! for message passing.\n\n\/\/ Do not remove on snapshot creation. Needed for bootstrap.

The cleanup module tracks what values need to be cleaned up as scopes\n\/\/! are exited, either via panic or just normal control flow. The basic\n\/\/! idea is that the function context maintains a stack of cleanup scopes\n\/\/! that are pushed\/popped as we traverse the AST tree. There is typically\n\/\/! at least one cleanup scope per AST node; some AST nodes may introduce\n\/\/! additional temporary scopes.\n\/\/!\n\/\/! Cleanup items can be scheduled into any of the scopes on the stack.\n\/\/! Typically, when a scope is popped, we will also generate the code for\n\/\/! each of its cleanups at that time. This corresponds to a normal exit\n\/\/! from a block (for example, an expression completing evaluation\n\/\/! successfully without panic). However, it is also possible to pop a\n\/\/! block *without* executing its cleanups; this is typically used to\n\/\/! guard intermediate values that must be cleaned up on panic, but not\n\/\/! if everything goes right. See the section on custom scopes below for\n\/\/! more details.\n\/\/!\n\/\/! Cleanup scopes come in three kinds:\n\/\/!\n\/\/! - **AST scopes:** each AST node in a function body has a corresponding\n\/\/!   AST scope. We push the AST scope when we start generate code for an AST\n\/\/!   node and pop it once the AST node has been fully generated.\n\/\/! - **Loop scopes:** loops have an additional cleanup scope. Cleanups are\n\/\/!   never scheduled into loop scopes; instead, they are used to record the\n\/\/!   basic blocks that we should branch to when a `continue` or `break` statement\n\/\/!   is encountered.\n\/\/! - **Custom scopes:** custom scopes are typically used to ensure cleanup\n\/\/!   of intermediate values.\n\/\/!\n\/\/! ### When to schedule cleanup\n\/\/!\n\/\/! Although the cleanup system is intended to *feel* fairly declarative,\n\/\/! it's still important to time calls to `schedule_clean()` correctly.\n\/\/! Basically, you should not schedule cleanup for memory until it has\n\/\/! been initialized, because if an unwind should occur before the memory\n\/\/! is fully initialized, then the cleanup will run and try to free or\n\/\/! drop uninitialized memory. If the initialization itself produces\n\/\/! byproducts that need to be freed, then you should use temporary custom\n\/\/! scopes to ensure that those byproducts will get freed on unwind.  For\n\/\/! example, an expression like `box foo()` will first allocate a box in the\n\/\/! heap and then call `foo()` -- if `foo()` should panic, this box needs\n\/\/! to be *shallowly* freed.\n\/\/!\n\/\/! ### Long-distance jumps\n\/\/!\n\/\/! In addition to popping a scope, which corresponds to normal control\n\/\/! flow exiting the scope, we may also *jump out* of a scope into some\n\/\/! earlier scope on the stack. This can occur in response to a `return`,\n\/\/! `break`, or `continue` statement, but also in response to panic. In\n\/\/! any of these cases, we will generate a series of cleanup blocks for\n\/\/! each of the scopes that is exited. So, if the stack contains scopes A\n\/\/! ... Z, and we break out of a loop whose corresponding cleanup scope is\n\/\/! X, we would generate cleanup blocks for the cleanups in X, Y, and Z.\n\/\/! After cleanup is done we would branch to the exit point for scope X.\n\/\/! But if panic should occur, we would generate cleanups for all the\n\/\/! scopes from A to Z and then resume the unwind process afterwards.\n\/\/!\n\/\/! To avoid generating tons of code, we cache the cleanup blocks that we\n\/\/! create for breaks, returns, unwinds, and other jumps. Whenever a new\n\/\/! cleanup is scheduled, though, we must clear these cached blocks. A\n\/\/! possible improvement would be to keep the cached blocks but simply\n\/\/! generate a new block which performs the additional cleanup and then\n\/\/! branches to the existing cached blocks.\n\/\/!\n\/\/! ### AST and loop cleanup scopes\n\/\/!\n\/\/! AST cleanup scopes are pushed when we begin and end processing an AST\n\/\/! node. They are used to house cleanups related to rvalue temporary that\n\/\/! get referenced (e.g., due to an expression like `&Foo()`). Whenever an\n\/\/! AST scope is popped, we always trans all the cleanups, adding the cleanup\n\/\/! code after the postdominator of the AST node.\n\/\/!\n\/\/! AST nodes that represent breakable loops also push a loop scope; the\n\/\/! loop scope never has any actual cleanups, it's just used to point to\n\/\/! the basic blocks where control should flow after a \"continue\" or\n\/\/! \"break\" statement. Popping a loop scope never generates code.\n\/\/!\n\/\/! ### Custom cleanup scopes\n\/\/!\n\/\/! Custom cleanup scopes are used for a variety of purposes. The most\n\/\/! common though is to handle temporary byproducts, where cleanup only\n\/\/! needs to occur on panic. The general strategy is to push a custom\n\/\/! cleanup scope, schedule *shallow* cleanups into the custom scope, and\n\/\/! then pop the custom scope (without transing the cleanups) when\n\/\/! execution succeeds normally. This way the cleanups are only trans'd on\n\/\/! unwind, and only up until the point where execution succeeded, at\n\/\/! which time the complete value should be stored in an lvalue or some\n\/\/! other place where normal cleanup applies.\n\/\/!\n\/\/! To spell it out, here is an example. Imagine an expression `box expr`.\n\/\/! We would basically:\n\/\/!\n\/\/! 1. Push a custom cleanup scope C.\n\/\/! 2. Allocate the box.\n\/\/! 3. Schedule a shallow free in the scope C.\n\/\/! 4. Trans `expr` into the box.\n\/\/! 5. Pop the scope C.\n\/\/! 6. Return the box as an rvalue.\n\/\/!\n\/\/! This way, if a panic occurs while transing `expr`, the custom\n\/\/! cleanup scope C is pushed and hence the box will be freed.

If you are trying to cast a numeric type\nto a bool, you can compare it with zero instead:\n\n```\nlet x = 5;\n\n\/\/ Ok\nlet x_is_nonzero = x != 0;\n\n\/\/ Not allowed, won't compile\nlet x_is_nonzero = x as bool;\n```\n\"##,\n\nE0062: r##\"\nThis error indicates that during an attempt to build a struct or struct-like\nenum variant, one of the fields was specified more than once. Each field should\nbe specified exactly one time.\n\"##,\n\nE0063: r##\"\nThis error indicates that during an attempt to build a struct or struct-like\nenum variant, one of the fields was not provided. Each field should be specified\nexactly once.\n\"##,\n\nE0067: r##\"\nThe left-hand side of an assignment operator must be an lvalue expression. An\nlvalue expression represents a memory location and includes item paths (ie,\nnamespaced variables), dereferences, indexing expressions, and field references.\n\n```\nuse std::collections::LinkedList;\n\n\/\/ Good\nlet mut list = LinkedList::new();\n\n\n\/\/ Bad: assignment to non-lvalue expression\nLinkedList::new() += 1;\n```\n\"##,\n\nE0081: r##\"\nEnum discriminants are used to differentiate enum variants stored in memory.\nThis error indicates that the same value was used for two or more variants,\nmaking them impossible to tell apart.\n\n```\n\/\/ Good.\nenum Enum {\n    P,\n    X = 3,\n    Y = 5\n}\n\n\/\/ Bad.\nenum Enum {\n    P = 3,\n    X = 3,\n    Y = 5\n}\n```\n\nNote that variants without a manually specified discriminant are numbered from\ntop to bottom starting from 0, so clashes can occur with seemingly unrelated\nvariants.\n\n```\nenum Bad {\n    X,\n    Y = 0\n}\n```\n\nHere `X` will have already been assigned the discriminant 0 by the time `Y` is\nencountered, so a conflict occurs.\n\"##,\n\nE0082: r##\"\nThe default type for enum discriminants is `isize`, but it can be adjusted by\nadding the `repr` attribute to the enum declaration. This error indicates that\nan integer literal given as a discriminant is not a member of the discriminant\ntype. For example:\n\n```\n#[repr(u8)]\nenum Thing {\n    A = 1024,\n    B = 5\n}\n```\n\nHere, 1024 lies outside the valid range for `u8`, so the discriminant for `A` is\ninvalid. You may want to change representation types to fix this, or else change\ninvalid discriminant values so that they fit within the existing type.\n\nNote also that without a representation manually defined, the compiler will\noptimize by using the smallest integer type possible.\n\"##,\n\nE0083: r##\"\nAt present, it's not possible to define a custom representation for an enum with\na single variant. As a workaround you can add a `Dummy` variant.\n\nSee: https:\/\/github.com\/rust-lang\/rust\/issues\/10292\n\"##,\n\nE0084: r##\"\nIt is impossible to define an integer type to be used to represent zero-variant\nenum values because there are no zero-variant enum values. There is no way to\nconstruct an instance of the following type using only safe code:\n\n```\nenum Empty {}\n```\n\"##,\n\nE0131: r##\"\nIt is not possible to define `main` with type parameters, or even with function\nparameters. When `main` is present, it must take no arguments and return `()`.\n\"##,\n\nE0132: r##\"\nIt is not possible to declare type parameters on a function that has the `start`\nattribute.

If you are trying to cast a numeric type\nto a bool, you can compare it with zero instead:\n\n```\nlet x = 5;\n\n\/\/ Ok\nlet x_is_nonzero = x != 0;\n\n\/\/ Not allowed, won't compile\nlet x_is_nonzero = x as bool;\n```\n\"##,\n\nE0062: r##\"\nThis error indicates that during an attempt to build a struct or struct-like\nenum variant, one of the fields was specified more than once. Each field should\nbe specified exactly one time.\n\"##,\n\nE0063: r##\"\nThis error indicates that during an attempt to build a struct or struct-like\nenum variant, one of the fields was not provided. Each field should be specified\nexactly once.\n\"##,\n\nE0067: r##\"\nThe left-hand side of an assignment operator must be an lvalue expression. An\nlvalue expression represents a memory location and includes item paths (ie,\nnamespaced variables), dereferences, indexing expressions, and field references.\n\n```\nuse std::collections::LinkedList;\n\n\/\/ Good\nlet mut list = LinkedList::new();\n\n\n\/\/ Bad: assignment to non-lvalue expression\nLinkedList::new() += 1;\n```\n\"##,\n\nE0081: r##\"\nEnum discriminants are used to differentiate enum variants stored in memory.\nThis error indicates that the same value was used for two or more variants,\nmaking them impossible to tell apart.\n\n```\n\/\/ Good.\nenum Enum {\n    P,\n    X = 3,\n    Y = 5\n}\n\n\/\/ Bad.\nenum Enum {\n    P = 3,\n    X = 3,\n    Y = 5\n}\n```\n\nNote that variants without a manually specified discriminant are numbered from\ntop to bottom starting from 0, so clashes can occur with seemingly unrelated\nvariants.\n\n```\nenum Bad {\n    X,\n    Y = 0\n}\n```\n\nHere `X` will have already been assigned the discriminant 0 by the time `Y` is\nencountered, so a conflict occurs.\n\"##,\n\nE0082: r##\"\nThe default type for enum discriminants is `isize`, but it can be adjusted by\nadding the `repr` attribute to the enum declaration. This error indicates that\nan integer literal given as a discriminant is not a member of the discriminant\ntype. For example:\n\n```\n#[repr(u8)]\nenum Thing {\n    A = 1024,\n    B = 5\n}\n```\n\nHere, 1024 lies outside the valid range for `u8`, so the discriminant for `A` is\ninvalid. You may want to change representation types to fix this, or else change\ninvalid discriminant values so that they fit within the existing type.\n\nNote also that without a representation manually defined, the compiler will\noptimize by using the smallest integer type possible.\n\"##,\n\nE0083: r##\"\nAt present, it's not possible to define a custom representation for an enum with\na single variant. As a workaround you can add a `Dummy` variant.\n\nSee: https:\/\/github.com\/rust-lang\/rust\/issues\/10292\n\"##,\n\nE0084: r##\"\nIt is impossible to define an integer type to be used to represent zero-variant\nenum values because there are no zero-variant enum values. There is no way to\nconstruct an instance of the following type using only safe code:\n\n```\nenum Empty {}\n```\n\"##,\n\nE0131: r##\"\nIt is not possible to define `main` with type parameters, or even with function\nparameters. When `main` is present, it must take no arguments and return `()`.\n\"##,\n\nE0132: r##\"\nIt is not possible to declare type parameters on a function that has the `start`\nattribute.

The Rust Core Library is the dependency-free foundation of [The\n\/\/! Rust Standard Library](..\/std\/index.html). It is the portable glue\n\/\/! between the language and its libraries, defining the intrinsic and\n\/\/! primitive building blocks of all Rust code. It links to no\n\/\/! upstream libraries, no system libraries, and no libc.\n\/\/!\n\/\/! The core library is *minimal*: it isn't even aware of heap allocation,\n\/\/! nor does it provide concurrency or I\/O. These things require\n\/\/! platform integration, and this library is platform-agnostic.\n\/\/!\n\/\/! *It is not recommended to use the core library*. The stable\n\/\/! functionality of libcore is reexported from the\n\/\/! [standard library](..\/std\/index.html). The composition of this library is\n\/\/! subject to change over time; only the interface exposed through libstd is\n\/\/! intended to be stable.\n\/\/!\n\/\/! # How to use the core library\n\/\/!\n\/\/ FIXME: Fill me in with more detail when the interface settles\n\/\/! This library is built on the assumption of a few existing symbols:\n\/\/!\n\/\/! * `memcpy`, `memcmp`, `memset` - These are core memory routines which are\n\/\/!   often generated by LLVM. Additionally, this library can make explicit\n\/\/!   calls to these functions. Their signatures are the same as found in C.\n\/\/!

The Rust Core Library is the dependency-free foundation of [The\n\/\/! Rust Standard Library](..\/std\/index.html). It is the portable glue\n\/\/! between the language and its libraries, defining the intrinsic and\n\/\/! primitive building blocks of all Rust code. It links to no\n\/\/! upstream libraries, no system libraries, and no libc.\n\/\/!\n\/\/! The core library is *minimal*: it isn't even aware of heap allocation,\n\/\/! nor does it provide concurrency or I\/O. These things require\n\/\/! platform integration, and this library is platform-agnostic.\n\/\/!\n\/\/! *It is not recommended to use the core library*. The stable\n\/\/! functionality of libcore is reexported from the\n\/\/! [standard library](..\/std\/index.html). The composition of this library is\n\/\/! subject to change over time; only the interface exposed through libstd is\n\/\/! intended to be stable.\n\/\/!\n\/\/! # How to use the core library\n\/\/!\n\/\/ FIXME: Fill me in with more detail when the interface settles\n\/\/! This library is built on the assumption of a few existing symbols:\n\/\/!\n\/\/! * `memcpy`, `memcmp`, `memset` - These are core memory routines which are\n\/\/!   often generated by LLVM. Additionally, this library can make explicit\n\/\/!   calls to these functions. Their signatures are the same as found in C.\n\/\/!   These functions are often provided by the system libc, but can also be\n\/\/!   provided by the [rlibc crate](https:\/\/crates.io\/crates\/rlibc).\n\/\/!\n\/\/! * `rust_begin_unwind` - This function takes three arguments, a\n\/\/!   `fmt::Arguments`, a `&str`, and a `usize`. These three arguments dictate\n\/\/!   the panic message, the file at which panic was invoked, and the line.\n\/\/!   It is up to consumers of this core library to define this panic\n\/\/!   function; it is only required to never return.\n\n\/\/ Since libcore defines many fundamental lang items, all tests live in a\n\/\/ separate crate, libcoretest, to avoid bizarre issues.\n\n#![crate_name = \"core\"]\n#![unstable(feature = \"core\")]\n#![staged_api]\n#![crate_type = \"rlib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n       html_root_url = \"http:\/\/doc.rust-lang.org\/nightly\/\",\n       html_playground_url = \"http:\/\/play.rust-lang.org\/\")]\n\n#![feature(no_std)]\n#![no_std]\n#![allow(raw_pointer_derive)]\n#![deny(missing_docs)]\n\n#![feature(int_uint)]\n#![feature(intrinsics, lang_items)]\n#![feature(on_unimplemented)]\n#![feature(simd, unsafe_destructor)]\n#![feature(staged_api)]\n#![feature(unboxed_closures)]\n#![feature(rustc_attrs)]\n#![feature(optin_builtin_traits)]\n#![feature(concat_idents)]\n\n#[macro_use]\nmod macros;\n\n#[macro_use]\nmod cmp_macros;\n\n#[path = \"num\/float_macros.rs\"]\n#[macro_use]\nmod float_macros;\n\n#[path = \"num\/int_macros.rs\"]\n#[macro_use]\nmod int_macros;\n\n#[path = \"num\/uint_macros.rs\"]\n#[macro_use]\nmod uint_macros;\n\n#[path = \"num\/isize.rs\"]  pub mod isize;\n#[path = \"num\/i8.rs\"]   pub mod i8;\n#[path = \"num\/i16.rs\"]  pub mod i16;\n#[path = \"num\/i32.rs\"]  pub mod i32;\n#[path = \"num\/i64.rs\"]  pub mod i64;\n\n#[path = \"num\/usize.rs\"] pub mod usize;\n#[path = \"num\/u8.rs\"]   pub mod u8;\n#[path = \"num\/u16.rs\"]  pub mod u16;\n#[path = \"num\/u32.rs\"]  pub mod u32;\n#[path = \"num\/u64.rs\"]  pub mod u64;\n\n#[path = \"num\/f32.rs\"]   pub mod f32;\n#[path = \"num\/f64.rs\"]   pub mod f64;\n\npub mod num;\n\n\/* The libcore prelude, not as all-encompassing as the libstd prelude *\/\n\npub mod prelude;\n\n\/* Core modules for ownership management *\/\n\npub mod intrinsics;\npub mod mem;\npub mod nonzero;\npub mod ptr;\n\n\/* Core language traits *\/\n\npub mod marker;\npub mod ops;\npub mod cmp;\npub mod clone;\npub mod default;\n\n\/* Core types and methods on primitives *\/\n\npub mod any;\npub mod atomic;\npub mod cell;\npub mod char;\npub mod panicking;\npub mod finally;\npub mod iter;\npub mod option;\npub mod raw;\npub mod result;\npub mod simd;\npub mod slice;\npub mod str;\npub mod hash;\npub mod fmt;\npub mod error;\n\n#[doc(primitive = \"bool\")]\nmod bool {\n}\n\n\/\/ note: does not need to be public\nmod tuple;\nmod array;\n\n#[doc(hidden)]\nmod core {\n    pub use panicking;\n    pub use fmt;\n    pub use clone;\n    pub use cmp;\n    pub use hash;\n    pub use marker;\n    pub use option;\n    pub use iter;\n}\n\n#[doc(hidden)]\nmod std {\n    \/\/ range syntax\n    pub use ops;\n}\n<|endoftext|>"}

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`kinds`](kinds\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an\n\/\/! array, lives in the [`vec`](vec\/index.html) module. References to\n\/\/! arrays, `&[T]`, more commonly called \"slices\", are built-in types\n\/\/! for which the [`slice`](slice\/index.html) module defines many\n\/\/! methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](from_str\/index.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`task`](task\/index.html) module contains Rust's threading abstractions,\n\/\/! while [`comm`](comm\/index.html) contains the channel types for message\n\/\/! passing. [`sync`](sync\/index.html) contains further, primitive, shared\n\/\/! memory types, including [`atomics`](sync\/atomics\/index.html).\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the [`io`](io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\n#![crate_name = \"std\"]\n#![unstable]\n#![comment = \"The Rust standard library\"]\n#![license = \"MIT\/ASL2\"]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n       html_root_url = \"http:\/\/doc.rust-lang.org\/nightly\/\",\n       html_playground_url = \"http:\/\/play.rust-lang.org\/\")]\n\n#![allow(unknown_features)]\n#![feature(macro_rules, globs, linkage)]\n#![feature(default_type_params, phase, lang_items, unsafe_destructor)]\n#![feature(import_shadowing, slicing_syntax)]\n\n\/\/ Don't link to std.

Unfortunately our inference has\n\/\/ become fairly complex and so there are a number of options to\n\/\/ control *just how much* you want to resolve and how you want to do\n\/\/ it.\n\/\/\n\/\/ # Controlling the scope of resolution\n\/\/\n\/\/ The options resolve_* determine what kinds of variables get\n\/\/ resolved.  Generally resolution starts with a top-level type\n\/\/ variable; we will always resolve this.  However, once we have\n\/\/ resolved that variable, we may end up with a type that still\n\/\/ contains type variables.  For example, if we resolve `<T0>` we may\n\/\/ end up with something like `[<T1>]`.  If the option\n\/\/ `resolve_nested_tvar` is passed, we will then go and recursively\n\/\/ resolve `<T1>`.\n\/\/\n\/\/ The options `resolve_rvar` controls whether we resolve region\n\/\/ variables. The options `resolve_fvar` and `resolve_ivar` control\n\/\/ whether we resolve floating point and integral variables,\n\/\/ respectively.\n\/\/\n\/\/ # What do if things are unconstrained\n\/\/\n\/\/ Sometimes we will encounter a variable that has no constraints, and\n\/\/ therefore cannot sensibly be mapped to any particular result.  By\n\/\/ default, we will leave such variables as is (so you will get back a\n\/\/ variable in your result).  The options force_* will cause the\n\/\/ resolution to fail in this case intead, except for the case of\n\/\/ integral variables, which resolve to `int` if forced.\n\/\/\n\/\/ # resolve_all and force_all\n\/\/\n\/\/ The options are a bit set, so you can use the *_all to resolve or\n\/\/ force all kinds of variables (including those we may add in the\n\/\/ future).  If you want to resolve everything but one type, you are\n\/\/ probably better off writing `resolve_all - resolve_ivar`.\n\n\nuse middle::ty::{FloatVar, FloatVid, IntVar, IntVid, RegionVid, TyVar, TyVid};\nuse middle::ty::{type_is_bot, IntType, UintType};\nuse middle::ty;\nuse middle::ty_fold;\nuse middle::typeck::infer::{Bounds, cyclic_ty, fixup_err, fres, InferCtxt};\nuse middle::typeck::infer::{region_var_bound_by_region_var, unresolved_ty};\nuse middle::typeck::infer::to_str::InferStr;\nuse middle::typeck::infer::unify::{Root, UnifyInferCtxtMethods};\nuse util::common::{indent, indenter};\nuse util::ppaux::ty_to_str;\n\nuse syntax::ast;\n\npub static resolve_nested_tvar: uint = 0b0000000001;\npub static resolve_rvar: uint        = 0b0000000010;\npub static resolve_ivar: uint        = 0b0000000100;\npub static resolve_fvar: uint        = 0b0000001000;\npub static resolve_fnvar: uint       = 0b0000010000;\npub static resolve_all: uint         = 0b0000011111;\npub static force_tvar: uint          = 0b0000100000;\npub static force_rvar: uint          = 0b0001000000;\npub static force_ivar: uint          = 0b0010000000;\npub static force_fvar: uint          = 0b0100000000;\npub static force_fnvar: uint         = 0b1000000000;\npub static force_all: uint           = 0b1111100000;\n\npub static not_regions: uint         = !(force_rvar | resolve_rvar);\n\npub static try_resolve_tvar_shallow: uint = 0;\npub static resolve_and_force_all_but_regions: uint =\n    (resolve_all | force_all) & not_regions;\n\npub struct ResolveState<'a> {\n    infcx: &'a InferCtxt<'a>,\n    modes: uint,\n    err: Option<fixup_err>,\n    v_seen: Vec<TyVid> ,\n    type_depth: uint\n}\n\npub fn resolver<'a>(infcx: &'a InferCtxt, modes: uint) -> ResolveState<'a> {\n    ResolveState {\n        infcx: infcx,\n        modes: modes,\n        err: None,\n        v_seen: Vec::new(),\n        type_depth: 0\n    }\n}\n\nimpl<'a> ty_fold::TypeFolder for ResolveState<'a> {\n    fn tcx<'a>(&'a self) -> &'a ty::ctxt {\n        self.infcx.tcx\n    }\n\n    fn fold_ty(&mut self, t: ty::t) -> ty::t {\n        self.resolve_type(t)\n    }\n\n    fn fold_region(&mut self, r: ty::Region) -> ty::Region {\n        self.resolve_region(r)\n    }\n}\n\nimpl<'a> ResolveState<'a> {\n    pub fn should(&mut self, mode: uint) -> bool {\n        (self.modes & mode) == mode\n    }\n\n    pub fn resolve_type_chk(&mut self, typ: ty::t) -> fres<ty::t> {\n        self.err = None;\n\n        debug!(\"Resolving {} (modes={:x})\",\n               ty_to_str(self.infcx.tcx, typ),\n               self.modes);\n\n        \/\/ n.b.

Differs\n\/\/! from the ring buffer-backed VecDeque in that this structure\n\/\/! is lockless and threadsafe.  Threadsafety is achieved using only\n\/\/! CAS operations, making this queue ideal for high throughput.  This\n\/\/! queue is not ideal for situations where a long wait is expected\n\/\/! as any getter is blocked in a spinlock until an item is put.  Locks\n\/\/! due to resource starvation are avoided by yielding the spin lock to\n\/\/! the scheduler every few thousand iterations.  This queue is cache-aware\n\/\/! and performs best with cache line sizes of 64 bytes.\n\/\/!\n\/\/! Because this queue is threadsafe, it is safe to pass an Arc around\n\/\/! to spawned threads and call put, without wrapping the struct itself\n\/\/! in a mutex.\n\n\/\/!

This buffer is similar to the buffer\n\/\/! described here: http:\/\/www.1024cores.net\/home\/lock-free-algorithms\/queues\/bounded-mpmc-queue\n\/\/! with some minor additions.\n\/\/!\n\/\/! A statically-sized ring buffer that acts as an MPMC queue.  Differs\n\/\/! from the ring buffer-backed VecDeque in that this structure\n\/\/! is lockless and threadsafe.  Threadsafety is achieved using only\n\/\/! CAS operations, making this queue ideal for high throughput.  This\n\/\/! queue is not ideal for situations where a long wait is expected\n\/\/! as any getter is blocked in a spinlock until an item is put.  Locks\n\/\/! due to resource starvation are avoided by yielding the spin lock to\n\/\/! the scheduler every few thousand iterations.  This queue is cache-aware\n\/\/! and performs best with cache line sizes of 64 bytes.\n\/\/!\n\/\/! Because this queue is threadsafe, it is safe to pass an Arc around\n\/\/! to spawned threads and call put, without wrapping the struct itself\n\/\/! in a mutex.\n\n\/\/!

{"text":"<commit_before><commit_msg>move session to separate crate<commit_after>\/\/! User sessions.\n\/\/!\n\/\/! Actix provides a general solution for session management. The\n\/\/! [**SessionStorage**](struct.SessionStorage.html)\n\/\/! middleware can be used with different backend types to store session\n\/\/! data in different backends.\n\/\/!\n\/\/! By default, only cookie session backend is implemented. Other\n\/\/! backend implementations can be added.\n\/\/!\n\/\/! [**CookieSessionBackend**](struct.CookieSessionBackend.html)\n\/\/! uses cookies as session storage. `CookieSessionBackend` creates sessions\n\/\/! which are limited to storing fewer than 4000 bytes of data, as the payload\n\/\/! must fit into a single cookie. An internal server error is generated if a\n\/\/! session contains more than 4000 bytes.\n\/\/!\n\/\/! A cookie may have a security policy of *signed* or *private*. Each has\n\/\/! a respective `CookieSessionBackend` constructor.\n\/\/!\n\/\/! A *signed* cookie may be viewed but not modified by the client. A *private*\n\/\/! cookie may neither be viewed nor modified by the client.\n\/\/!\n\/\/! The constructors take a key as an argument. This is the private key\n\/\/! for cookie session - when this value is changed, all session data is lost.\n\/\/!\n\/\/! In general, you create a `SessionStorage` middleware and initialize it\n\/\/! with specific backend implementation, such as a `CookieSessionBackend`.\n\/\/! To access session data,\n\/\/! [*HttpRequest::session()*](trait.RequestSession.html#tymethod.session)\n\/\/! must be used. This method returns a\n\/\/! [*Session*](struct.Session.html) object, which allows us to get or set\n\/\/! session data.\n\/\/!\n\/\/! ```rust\n\/\/! # extern crate actix_web;\n\/\/! # extern crate actix;\n\/\/! use actix_web::{server, App, HttpRequest, Result};\n\/\/! use actix_web::middleware::session::{RequestSession, SessionStorage, CookieSessionBackend};\n\/\/!\n\/\/! fn index(req: HttpRequest) -> Result<&'static str> {\n\/\/!     \/\/ access session data\n\/\/!     if let Some(count) = req.session().get::<i32>(\"counter\")? {\n\/\/!         println!(\"SESSION value: {}\", count);\n\/\/!         req.session().set(\"counter\", count+1)?;\n\/\/!     } else {\n\/\/!         req.session().set(\"counter\", 1)?;\n\/\/!     }\n\/\/!\n\/\/!

`CookieSessionBackend` creates sessions which are limited to storing\n\/\/\/ fewer than 4000 bytes of data (as the payload must fit into a single\n\/\/\/ cookie). An Internal Server Error is generated if the session contains more\n\/\/\/ than 4000 bytes.\n\/\/\/\n\/\/\/ A cookie may have a security policy of *signed* or *private*. Each has a\n\/\/\/ respective `CookieSessionBackend` constructor.\n\/\/\/\n\/\/\/ A *signed* cookie is stored on the client as plaintext alongside\n\/\/\/ a signature such that the cookie may be viewed but not modified by the\n\/\/\/ client.\n\/\/\/\n\/\/\/ A *private* cookie is stored on the client as encrypted text\n\/\/\/ such that it may neither be viewed nor modified by the client.\n\/\/\/\n\/\/\/ The constructors take a key as an argument.\n\/\/\/ This is the private key for cookie session - when this value is changed,\n\/\/\/ all session data is lost. The constructors will panic if the key is less\n\/\/\/ than 32 bytes in length.\n\/\/\/\n\/\/\/ The backend relies on `cookie` crate to create and read cookies.\n\/\/\/ By default all cookies are percent encoded, but certain symbols may\n\/\/\/ cause troubles when reading cookie, if they are not properly percent encoded.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ # extern crate actix_web;\n\/\/\/ use actix_web::middleware::session::CookieSessionBackend;\n\/\/\/\n\/\/\/ # fn main() {\n\/\/\/ let backend: CookieSessionBackend = CookieSessionBackend::signed(&[0;

They cannot be implemented by user code, but are instead implemented\n\/\/! by the compiler automatically for the types to which they apply.\n\n\/\/\/ Types able to be transferred across task boundaries.\n#[lang=\"send\"]\npub trait Send for Sized? : 'static {\n    \/\/ empty.\n}\n\n\/\/\/ Types with a constant size known at compile-time.\n#[lang=\"sized\"]\npub trait Sized for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be copied by simply copying bits (i.e. `memcpy`).\n#[lang=\"copy\"]\npub trait Copy for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be safely shared between tasks when aliased.\n\/\/\/\n\/\/\/ The precise definition is: a type `T` is `Sync` if `&T` is\n\/\/\/ thread-safe. In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `tcx.types` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- outlives: outlives inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\n#![doc(html_logo_url =

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `tcx.types` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- outlives: outlives inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\n#![doc(html_logo_url =

They cannot be implemented by user code, but are instead implemented\n\/\/! by the compiler automatically for the types to which they apply.\n\n\/\/\/ Types able to be transferred across task boundaries.\n#[lang=\"send\"]\npub trait Send for Sized? : 'static {\n    \/\/ empty.\n}\n\n\/\/\/ Types with a constant size known at compile-time.\n#[lang=\"sized\"]\npub trait Sized for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be copied by simply copying bits (i.e. `memcpy`).\n#[lang=\"copy\"]\npub trait Copy for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be safely shared between tasks when aliased.\n\/\/\/\n\/\/\/ The precise definition is: a type `T` is `Sync` if `&T` is\n\/\/\/ thread-safe. In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

It's most commonly seen when attempting to\nreturn a closure:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be unsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable.

The arena uses ~[u8] vectors as a backing store to\n\/\/ allocate objects from. For each allocated object, the arena stores\n\/\/ a pointer to the type descriptor followed by the\n\/\/ object. (Potentially with alignment padding after each of them.)\n\/\/ When the arena is destroyed, it iterates through all of its chunks,\n\/\/ and uses the tydesc information to trace through the objects,\n\/\/ calling the destructors on them.\n\/\/ One subtle point that needs to be addressed is how to handle\n\/\/ failures while running the user provided initializer function. It\n\/\/ is important to not run the destructor on uninitialized objects, but\n\/\/ how to detect them is somewhat subtle. Since alloc() can be invoked\n\/\/ recursively, it is not sufficient to simply exclude the most recent\n\/\/ object. To solve this without requiring extra space, we use the low\n\/\/ order bit of the tydesc pointer to encode whether the object it\n\/\/ describes has been fully initialized.\n\n\/\/ As an optimization, objects with destructors are stored in\n\/\/ different chunks than objects without destructors.

The arena uses ~[u8] vectors as a backing store to\n\/\/ allocate objects from. For each allocated object, the arena stores\n\/\/ a pointer to the type descriptor followed by the\n\/\/ object. (Potentially with alignment padding after each of them.)\n\/\/ When the arena is destroyed, it iterates through all of its chunks,\n\/\/ and uses the tydesc information to trace through the objects,\n\/\/ calling the destructors on them.\n\/\/ One subtle point that needs to be addressed is how to handle\n\/\/ failures while running the user provided initializer function. It\n\/\/ is important to not run the destructor on uninitialized objects, but\n\/\/ how to detect them is somewhat subtle. Since alloc() can be invoked\n\/\/ recursively, it is not sufficient to simply exclude the most recent\n\/\/ object. To solve this without requiring extra space, we use the low\n\/\/ order bit of the tydesc pointer to encode whether the object it\n\/\/ describes has been fully initialized.\n\n\/\/ As an optimization, objects with destructors are stored in\n\/\/ different chunks than objects without destructors. This reduces\n\/\/ overhead when initializing plain-old-data and means we don't need\n\/\/ to waste time running the destructors of POD.\n\n#[allow(missing_doc)];\n\n\nuse list::{List, Cons, Nil};\nuse list;\n\nuse std::at_vec;\nuse std::cast::{transmute, transmute_mut, transmute_mut_region};\nuse std::cast;\nuse std::cell::{Cell, RefCell};\nuse std::num;\nuse std::ptr;\nuse std::mem;\nuse std::uint;\nuse std::unstable::intrinsics;\nuse std::unstable::intrinsics::{TyDesc, get_tydesc};\n\n\/\/ The way arena uses arrays is really deeply awful.

An instance of `Future`\n\/\/! is handed back to represent that the work may be done later, and further\n\/\/! computations can be chained along with it as well.\n\/\/!\n\/\/! ```rust\n\/\/! extern crate futures;\n\/\/! extern crate futures_cpupool;\n\/\/!\n\/\/! use std::sync::mpsc::channel;\n\/\/!\n\/\/! use futures::{BoxFuture, Future};\n\/\/! use futures_cpupool::CpuPool;\n\/\/!\n\/\/! # fn long_running_future(a: u32) -> BoxFuture<u32, ()> { futures::done(Ok(a)).boxed() }\n\/\/! # fn main() {\n\/\/!\n\/\/! \/\/ Create a worker thread pool with four threads\n\/\/! let pool = CpuPool::new(4);\n\/\/!\n\/\/! \/\/ Execute some work on the thread pool, optionally closing over data.\n\/\/! let a = pool.spawn(long_running_future(2));\n\/\/! let b = pool.spawn(long_running_future(100));\n\/\/!\n\/\/! \/\/ Express some further computation once the work is completed on the thread\n\/\/! \/\/ pool.\n\/\/! let c = a.join(b).map(|(a, b)| a + b).wait().unwrap();\n\/\/!\n\/\/! \/\/ Print out the result\n\/\/! println!(\"{:?}\", c);\n\/\/! # }\n\/\/! ```\n\n#![deny(missing_docs)]\n\nextern crate crossbeam;\n\n#[macro_use]\nextern crate futures;\nextern crate num_cpus;\n\nuse std::panic::{self, AssertUnwindSafe};\nuse std::sync::Arc;\nuse std::sync::atomic::{AtomicUsize, Ordering};\nuse std::thread;\n\nuse crossbeam::sync::MsQueue;\nuse futures::{IntoFuture, Future, oneshot, Oneshot, Complete, Poll, Async};\nuse futures::task::{self, Run, Executor};\n\n\/\/\/ A thread pool intended to run CPU intensive work.\n\/\/\/\n\/\/\/ This thread pool will hand out futures representing the completed work\n\/\/\/ that happens on the thread pool itself, and the futures can then be later\n\/\/\/ composed with other work as part of an overall computation.\n\/\/\/\n\/\/\/ The worker threads associated with a thread pool are kept alive so long as\n\/\/\/ there is an open handle to the `CpuPool` or there is work running on them.

Converting decimal strings into IEEE 754 binary floating point numbers.\n\/\/!\n\/\/! # Problem statement\n\/\/!\n\/\/! We are given a decimal string such as `12.34e56`. This string consists of integral (`12`),\n\/\/! fractional (`45`), and exponent (`56`) parts. All parts are optional and interpreted as zero\n\/\/! when missing.\n\/\/!\n\/\/! We seek the IEEE 754 floating point number that is closest to the exact value of the decimal\n\/\/! string. It is well-known that many decimal strings do not have terminating representations in\n\/\/! base two, so we round to 0.5 units in the last place (in other words, as well as possible).\n\/\/! Ties, decimal values exactly half-way between two consecutive floats, are resolved with the\n\/\/! half-to-even strategy, also known as banker's rounding.\n\/\/!\n\/\/! Needless to say, this is quite hard, both in terms of implementation complexity and in terms\n\/\/! of CPU cycles taken.\n\/\/!\n\/\/! # Implementation\n\/\/!\n\/\/! First, we ignore signs. Or rather, we remove it at the very beginning of the conversion\n\/\/! process and re-apply it at the very end. This is correct in all edge cases since IEEE\n\/\/! floats are symmetric around zero, negating one simply flips the first bit.\n\/\/!\n\/\/! Then we remove the decimal point by adjusting the exponent: Conceptually, `12.34e56` turns\n\/\/! into `1234e54`, which we describe with a positive integer `f = 1234` and an integer `e = 54`.\n\/\/! The `(f, e)` representation is used by almost all code past the parsing stage.\n\/\/!\n\/\/! We then try a long chain of progressively more general and expensive special cases using\n\/\/! machine-sized integers and small, fixed-sized floating point numbers (first `f32`\/`f64`, then\n\/\/! a type with 64 bit significand, `Fp`). When all these fail, we bite the bullet and resort to a\n\/\/! simple but very slow algorithm that involved computing `f * 10^e` fully and doing an iterative\n\/\/! search for the best approximation.\n\/\/!\n\/\/! Primarily, this module and its children implement the algorithms described in:\n\/\/! \"How to Read Floating Point Numbers Accurately\" by William D. Clinger,\n\/\/! available online: http:\/\/citeseerx.ist.psu.edu\/viewdoc\/summary?doi=10.1.1.45.4152\n\/\/!\n\/\/! In addition, there are numerous helper functions that are used in the paper but not available\n\/\/! in Rust (or at least in core). Our version is additionally complicated by the need to handle\n\/\/! overflow and underflow and the desire to handle subnormal numbers.  Bellerophon and\n\/\/! Algorithm R have trouble with overflow, subnormals, and underflow. We conservatively switch to\n\/\/! Algorithm M (with the modifications described in section 8 of the paper) well before the\n\/\/! inputs get into the critical region.\n\/\/!\n\/\/! Another aspect that needs attention is the ``RawFloat`` trait by which almost all functions\n\/\/! are parametrized. One might think that it's enough to parse to `f64` and cast the result to\n\/\/! `f32`. Unfortunately this is not the world we live in, and this has nothing to do with using\n\/\/! base two or half-to-even rounding.\n\/\/!\n\/\/! Consider for example two types `d2` and `d4` representing a decimal type with two decimal\n\/\/! digits and four decimal digits each and take \"0.01499\" as input. Let's use half-up rounding.\n\/\/! Going directly to two decimal digits gives `0.01`, but if we round to four digits first,\n\/\/! we get `0.0150`, which is then rounded up to `0.02`. The same principle applies to other\n\/\/! operations as well, if you want 0.5 ULP accuracy you need to do *everything* in full precision\n\/\/! and round *exactly once, at the end*, by considering all truncated bits at once.\n\/\/!\n\/\/! FIXME Although some code duplication is necessary, perhaps parts of the code could be shuffled\n\/\/! around such that less code is duplicated. Large parts of the algorithms are independent of the\n\/\/! float type to output, or only needs access to a few constants, which could be passed in as\n\/\/! parameters.\n\/\/!\n\/\/! # Other\n\/\/!\n\/\/! The conversion should *never* panic. There are assertions and explicit panics in the code,\n\/\/! but they should never be triggered and only serve as internal sanity checks. Any panics should\n\/\/! be considered a bug.\n\/\/!\n\/\/! There are unit tests but they are woefully inadequate at ensuring correctness, they only cover\n\/\/! a small percentage of possible errors. Far more extensive tests are located in the directory\n\/\/! `src\/etc\/test-float-parse` as a Python script.\n\/\/!\n\/\/! A note on integer overflow: Many parts of this file perform arithmetic with the decimal\n\/\/! exponent `e`. Primarily, we shift the decimal point around: Before the first decimal digit,\n\/\/! after the last decimal digit, and so on. This could overflow if done carelessly. We rely on\n\/\/! the parsing submodule to only hand out sufficiently small exponents, where \"sufficient\" means\n\/\/! \"such that the exponent +\/- the number of decimal digits fits into a 64 bit integer\".\n\/\/! Larger exponents are accepted, but we don't do arithmetic with them, they are immediately\n\/\/! turned into {positive,negative} {zero,infinity}.\n\n#![doc(hidden)]\n#![unstable(feature = \"dec2flt\",\n            reason = \"internal routines only exposed for testing\",\n            issue = \"0\")]\n\nuse prelude::v1::*;\nuse fmt;\nuse str::FromStr;\n\nuse self::parse::{parse_decimal, Decimal, Sign};\nuse self::parse::ParseResult::{Valid, Invalid, ShortcutToInf, ShortcutToZero};\nuse self::num::digits_to_big;\nuse self::rawfp::RawFloat;\n\nmod algorithm;\nmod table;\nmod num;\n\/\/ These two have their own tests.\npub mod rawfp;\npub mod parse;\n\nmacro_rules! from_str_float_impl {\n    ($t:ty, $func:ident) => {\n        #[stable(feature = \"rust1\", since = \"1.0.0\")]\n        impl FromStr for $t {\n            type Err = ParseFloatError;\n\n            \/\/\/ Converts a string in base 10 to a float.\n            \/\/\/ Accepts an optional decimal exponent.\n            \/\/\/\n            \/\/\/ This function accepts strings such as\n            \/\/\/\n            \/\/\/ * '3.14'\n            \/\/\/ * '-3.14'\n            \/\/\/ * '2.5E10', or equivalently, '2.5e10'\n            \/\/\/ * '2.5E-10'\n            \/\/\/ * '.'

This string consists of integral (`12`),\n\/\/! fractional (`45`), and exponent (`56`) parts. All parts are optional and interpreted as zero\n\/\/! when missing.\n\/\/!\n\/\/! We seek the IEEE 754 floating point number that is closest to the exact value of the decimal\n\/\/! string. It is well-known that many decimal strings do not have terminating representations in\n\/\/! base two, so we round to 0.5 units in the last place (in other words, as well as possible).\n\/\/! Ties, decimal values exactly half-way between two consecutive floats, are resolved with the\n\/\/! half-to-even strategy, also known as banker's rounding.\n\/\/!\n\/\/! Needless to say, this is quite hard, both in terms of implementation complexity and in terms\n\/\/! of CPU cycles taken.\n\/\/!\n\/\/! # Implementation\n\/\/!\n\/\/! First, we ignore signs. Or rather, we remove it at the very beginning of the conversion\n\/\/! process and re-apply it at the very end. This is correct in all edge cases since IEEE\n\/\/! floats are symmetric around zero, negating one simply flips the first bit.\n\/\/!\n\/\/! Then we remove the decimal point by adjusting the exponent: Conceptually, `12.34e56` turns\n\/\/! into `1234e54`, which we describe with a positive integer `f = 1234` and an integer `e = 54`.\n\/\/! The `(f, e)` representation is used by almost all code past the parsing stage.\n\/\/!\n\/\/! We then try a long chain of progressively more general and expensive special cases using\n\/\/! machine-sized integers and small, fixed-sized floating point numbers (first `f32`\/`f64`, then\n\/\/! a type with 64 bit significand, `Fp`). When all these fail, we bite the bullet and resort to a\n\/\/! simple but very slow algorithm that involved computing `f * 10^e` fully and doing an iterative\n\/\/! search for the best approximation.\n\/\/!\n\/\/! Primarily, this module and its children implement the algorithms described in:\n\/\/! \"How to Read Floating Point Numbers Accurately\" by William D. Clinger,\n\/\/! available online: http:\/\/citeseerx.ist.psu.edu\/viewdoc\/summary?doi=10.1.1.45.4152\n\/\/!\n\/\/! In addition, there are numerous helper functions that are used in the paper but not available\n\/\/! in Rust (or at least in core). Our version is additionally complicated by the need to handle\n\/\/! overflow and underflow and the desire to handle subnormal numbers.  Bellerophon and\n\/\/! Algorithm R have trouble with overflow, subnormals, and underflow. We conservatively switch to\n\/\/! Algorithm M (with the modifications described in section 8 of the paper) well before the\n\/\/! inputs get into the critical region.\n\/\/!\n\/\/! Another aspect that needs attention is the ``RawFloat`` trait by which almost all functions\n\/\/! are parametrized. One might think that it's enough to parse to `f64` and cast the result to\n\/\/! `f32`. Unfortunately this is not the world we live in, and this has nothing to do with using\n\/\/! base two or half-to-even rounding.\n\/\/!\n\/\/! Consider for example two types `d2` and `d4` representing a decimal type with two decimal\n\/\/! digits and four decimal digits each and take \"0.01499\" as input. Let's use half-up rounding.\n\/\/! Going directly to two decimal digits gives `0.01`, but if we round to four digits first,\n\/\/! we get `0.0150`, which is then rounded up to `0.02`. The same principle applies to other\n\/\/! operations as well, if you want 0.5 ULP accuracy you need to do *everything* in full precision\n\/\/! and round *exactly once, at the end*, by considering all truncated bits at once.\n\/\/!\n\/\/! FIXME Although some code duplication is necessary, perhaps parts of the code could be shuffled\n\/\/! around such that less code is duplicated. Large parts of the algorithms are independent of the\n\/\/! float type to output, or only needs access to a few constants, which could be passed in as\n\/\/! parameters.\n\/\/!\n\/\/! # Other\n\/\/!\n\/\/! The conversion should *never* panic. There are assertions and explicit panics in the code,\n\/\/! but they should never be triggered and only serve as internal sanity checks. Any panics should\n\/\/! be considered a bug.\n\/\/!\n\/\/! There are unit tests but they are woefully inadequate at ensuring correctness, they only cover\n\/\/! a small percentage of possible errors. Far more extensive tests are located in the directory\n\/\/! `src\/etc\/test-float-parse` as a Python script.\n\/\/!\n\/\/! A note on integer overflow: Many parts of this file perform arithmetic with the decimal\n\/\/! exponent `e`. Primarily, we shift the decimal point around: Before the first decimal digit,\n\/\/! after the last decimal digit, and so on. This could overflow if done carelessly. We rely on\n\/\/! the parsing submodule to only hand out sufficiently small exponents, where \"sufficient\" means\n\/\/! \"such that the exponent +\/- the number of decimal digits fits into a 64 bit integer\".\n\/\/! Larger exponents are accepted, but we don't do arithmetic with them, they are immediately\n\/\/! turned into {positive,negative} {zero,infinity}.\n\n#![doc(hidden)]\n#![unstable(feature = \"dec2flt\",\n            reason = \"internal routines only exposed for testing\",\n            issue = \"0\")]\n\nuse prelude::v1::*;\nuse fmt;\nuse str::FromStr;\n\nuse self::parse::{parse_decimal, Decimal, Sign};\nuse self::parse::ParseResult::{Valid, Invalid, ShortcutToInf, ShortcutToZero};\nuse self::num::digits_to_big;\nuse self::rawfp::RawFloat;\n\nmod algorithm;\nmod table;\nmod num;\n\/\/ These two have their own tests.\npub mod rawfp;\npub mod parse;\n\nmacro_rules! from_str_float_impl {\n    ($t:ty) => {\n        #[stable(feature = \"rust1\", since = \"1.0.0\")]\n        impl FromStr for $t {\n            type Err = ParseFloatError;\n\n            \/\/\/ Converts a string in base 10 to a float.\n            \/\/\/ Accepts an optional decimal exponent.\n            \/\/\/\n            \/\/\/ This function accepts strings such as\n            \/\/\/\n            \/\/\/ * '3.14'\n            \/\/\/ * '-3.14'\n            \/\/\/ * '2.5E10', or equivalently, '2.5e10'\n            \/\/\/ * '2.5E-10'\n            \/\/\/ * '.'

The time delta between each slot of a time wheel is of a fixed\n\/\/\/ length, meaning that if a timeout is scheduled between two slots it'll end\n\/\/\/ up getting scheduled into the later slot.\npub struct TimerWheel<T> {\n    \/\/ Actual timer wheel itself.\n    \/\/\n    \/\/ Each slot represents a fixed duration of time, and this wheel also\n    \/\/ behaves like a ring buffer. All timeouts scheduled will correspond to one\n    \/\/ slot and therefore each slot has a linked list of timeouts scheduled in\n    \/\/ it. Right now linked lists are done through indices into the `slab`\n    \/\/ below.\n    \/\/\n    \/\/ Each slot also contains the next timeout associated with it (the minimum\n    \/\/ of the entire linked list).\n    wheel: Vec<Slot>,\n\n    \/\/ A slab containing all the timeout entries themselves. This is the memory\n    \/\/ backing the \"linked lists\" in the wheel above. Each entry has a prev\/next\n    \/\/ pointer (indices in this array) along with the data associated with the\n    \/\/ timeout and the time the timeout will fire.\n    slab: Slab<Entry<T>, usize>,\n\n    \/\/ The instant that this timer was created, through which all other timeout\n    \/\/ computations are relative to.\n    start: Instant,\n\n    \/\/ State used during `poll`. The `cur_wheel_tick` field is the current tick\n    \/\/ we've poll'd to. That is, all events from `cur_wheel_tick` to the\n    \/\/ actual current tick in time still need to be processed.\n    \/\/\n    \/\/ The `cur_slab_idx` variable is basically just an iterator over the linked\n    \/\/ list associated with a wheel slot.

when the coroutine resumed.\n *  In the scheduler\/coroutine model, every worker coroutine has a parent pointer pointing to\n *  the scheduler coroutine(which is a raw thread).\n *  Scheduler resumes a proper coroutine and set the parent pointer, like procedure I does.\n *  When a coroutine is awaken, it does some work like procedure II does.\n *  When a coroutine yield(io, finished, paniced or sched), it resumes its parent's context,\n *  like procedure III does.\n *  Now the scheduler is awake again and it simply decides whether to put the coroutine to queue again or not,\n *  according to the coroutine's return status.\n *  And last, the scheduler continues the scheduling loop and selects a proper coroutine to wake up.\n *\/\n\nuse std::default::Default;\nuse thunk::Thunk;\nuse

This crate has two arenas implemented: `TypedArena`, which is a simpler\n\/\/! arena but can only hold objects of a single type, and `Arena`, which is a\n\/\/! more complex, slower arena which can hold objects of any type.\n\n#![crate_name = \"arena\"]\n#![unstable(feature = \"rustc_private\", issue = \"27812\")]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       test(no_crate_inject, attr(deny(warnings))))]\n#![cfg_attr(not(stage0), deny(warnings))]\n\n#![feature(alloc)]\n#![feature(core_intrinsics)]\n#![feature(heap_api)]\n#![feature(heap_api)]\n#![feature(staged_api)]\n#![feature(dropck_parametricity)]\n#![cfg_attr(test, feature(test))]\n\n#![allow(deprecated)]\n\nextern crate alloc;\n\nuse std::cell::{Cell, RefCell};\nuse std::cmp;\nuse std::intrinsics;\nuse std::marker::{PhantomData, Send};\nuse std::mem;\nuse std::ptr;\n\nuse alloc::heap;\nuse alloc::raw_vec::RawVec;\n\n\/\/\/ A faster arena that can hold objects of only one type.\npub struct TypedArena<T> {\n    \/\/\/ A pointer to the next object to be allocated.\n    ptr: Cell<*mut T>,\n\n    \/\/\/ A pointer to the end of the allocated area.

{"text":"<commit_before><commit_msg>docs(groups): adds examples of ArgGroup usage<commit_after>\/\/\/ `ArgGroup`s are a family of related arguments and way for you to say, \"Any of these arguments\".\n\/\/\/ By placing arguments in a logical group, you can make easier requirement and exclusion rules\n\/\/\/ intead of having to list each individually, or when you want a rule to apply \"any but not all\"\n\/\/\/ arguments. \n\/\/\/\n\/\/\/ For instance, you can make an entire ArgGroup required, this means that one (and *only* one)\n\/\/\/ argument. from that group must be present. Using more than one argument from an ArgGroup causes\n\/\/\/ a failure (graceful exit).\n\/\/\/ \n\/\/\/ You can also do things such as name an ArgGroup as a confliction or requirement, meaning any \n\/\/\/ of the arguments that belong to that group will cause a failure if present, or must present\n\/\/\/ respectively.\n\/\/\/\n\/\/\/ Perhaps the most common use of `ArgGroup`s is to require one and *only* one argument to be \n\/\/\/ present out of a given set. Imagine that you had multiple arguments, and you want one of them to\n\/\/\/ be required, but making all of them required isn't feasible because perhaps they conflict with\n\/\/\/ each other. For example, lets say that you were building an application where one could set a\n\/\/\/ given version number by supplying a string with an option argument, i.e. `--set-ver v1.2.3`, you \n\/\/\/ also wanted to support automatically using a previous version number and simply incrementing one\n\/\/\/ of the three numbers. So you create three flags `--major`, `--minor`, and `--patch`. All of\n\/\/\/ these arguments shouldn't be used at one time but you want to specify that *at least one* of\n\/\/\/ them is used. For this, you can create a group.\n\nextern crate clap;\n\nuse clap::{App, Arg, ArgGroup};\n\nfn main() {\n    \/\/ Create application like normal\n    let matches = App::new(\"myapp\")\n                      \/\/ Add the version arguments\n                      .args_from_usage(\"--set-ver [ver] 'set version manually'\n                                        --major         'auto inc major'\n                                        --minor         'auto inc minor'\n                                        --patch         'auto inc patch'\")\n                      \/\/ Create a group, make it required, and add the above arguments\n                      .arg_group(ArgGroup::with_name(\"vers\")\n                                          .required(true)\n                                          .add_all(vec![\"vers\", \"major\", \"minor\", \"patch\"]))\n                      \/\/ Arguments can also be added to a group individually, these two arguments\n                      \/\/ are part of the \"input\" group which is not required\n                      .arg(Arg::from_usage(\"[INPUT_FILE] 'some regular input'\").group(\"input\"))\n                      .arg(Arg::from_usage(\"--spec-in [SPEC_IN] 'some special input argument'\").group(\"input\"))\n                      \/\/ Now let's assume we have a -c [config] argument which requires one of\n                      \/\/ (but **not** both) the \"input\" arguments\n                      .arg(Arg::with_name(\"config\").short(\"c\").takes_value(true).requires(\"input\"))\n                      .get_matches();\n\n    \/\/ Let's assume the old version 1.2.3\n    let mut major = 1;\n    let mut minor = 2;\n    let mut patch = 3;\n\n    \/\/ See if --set-ver was used to set the version manually\n    let version = if let Some(ver) = matches.value_of(\"ver\") {\n        format!(\"{}\", ver)\n    } else {\n        \/\/ Increment the one requested (in a real program, we'd reset the lower numbers)\n        let (maj, min, pat) = (matches.is_present(\"major\"), \n                                     matches.is_present(\"minor\"),\n                                     matches.is_present(\"patch\"));\n        match (maj, min, pat) {\n            (true, _, _) => major += 1,\n            (_, true, _) => minor += 1,\n            (_, _, true) => patch += 1,\n            _            => unreachable!(),\n        };\n        format!(\"{}.{}.{}\", major, minor, patch)\n    };\n\n    println!(\"Version: {}\", version);\n\n    \/\/ Check for usage of -c\n    if matches.is_present(\"config\") {\n        let input = matches.value_of(\"INPUT_FILE\").unwrap_or(matches.value_of(\"SPEC_IN\").unwrap());\n        println!(\"Doing work using input {} and config {}\", \n                                                     input, \n                                                     matches.value_of(\"config\").unwrap());\n    }\n\n\n}    <|endoftext|>"}

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable.

Hyper is a fast, modern HTTP implementation written in and for Rust. It\n\/\/! is a low-level typesafe abstraction over raw HTTP, providing an elegant\n\/\/! layer over \"stringly-typed\" HTTP.\n\/\/!\n\/\/! Hyper offers both an HTTP\/S client an HTTP server which can be used to drive\n\/\/! complex web applications written entirely in Rust.\n\/\/!\n\/\/! ## Internal Design\n\/\/!\n\/\/! Hyper is designed as a relatively low-level wrapper over raw HTTP. It should\n\/\/! allow the implementation of higher-level abstractions with as little pain as\n\/\/! possible, and should not irrevocably hide any information from its users.\n\/\/!\n\/\/! ### Common Functionality\n\/\/!\n\/\/! Functionality and code shared between the Server and Client implementations can\n\/\/! be found in `src` directly - this includes `NetworkStream`s, `Method`s,\n\/\/! `StatusCode`, and so on.\n\/\/!\n\/\/! #### Methods\n\/\/!\n\/\/! Methods are represented as a single `enum` to remain as simple as possible.\n\/\/! Extension Methods are represented as raw `String`s. A method's safety and\n\/\/! idempotence can be accessed using the `safe` and `idempotent` methods.\n\/\/!\n\/\/! #### StatusCode\n\/\/!\n\/\/! Status codes are also represented as a single, exhaustive, `enum`. This\n\/\/! representation is efficient, typesafe, and ergonomic as it allows the use of\n\/\/! `match` to disambiguate known status codes.\n\/\/!\n\/\/! #### Headers\n\/\/!\n\/\/! Hyper's header representation is likely the most complex API exposed by Hyper.\n\/\/!\n\/\/! Hyper's headers are an abstraction over an internal `HashMap` and provides a\n\/\/! typesafe API for interacting with headers that does not rely on the use of\n\/\/! \"string-typing.\"\n\/\/!\n\/\/! Each HTTP header in Hyper has an associated type and implementation of the\n\/\/! `Header` trait, which defines an HTTP headers name as a string, how to parse\n\/\/! that header, and how to format that header.\n\/\/!\n\/\/! Headers are then parsed from the string representation lazily when the typed\n\/\/! representation of a header is requested and formatted back into their string\n\/\/! representation when headers are written back to the client.\n\/\/!\n\/\/! #### NetworkStream and NetworkAcceptor\n\/\/!\n\/\/! These are found in `src\/net.rs` and define the interface that acceptors and\n\/\/! streams must fulfill for them to be used within Hyper. They are by and large\n\/\/! internal tools and you should only need to mess around with them if you want to\n\/\/! mock or replace `TcpStream` and `TcpAcceptor`.\n\/\/!\n\/\/! ### Server\n\/\/!\n\/\/! Server-specific functionality, such as `Request` and `Response`\n\/\/! representations, are found in in `src\/server`.\n\/\/!\n\/\/! #### Handler + Server\n\/\/!\n\/\/! A `Handler` in Hyper accepts a `Request` and `Response`. This is where\n\/\/! user-code can handle each connection. The server accepts connections in a\n\/\/! task pool with a customizable number of threads, and passes the Request \/\n\/\/! Response to the handler.\n\/\/!\n\/\/! #### Request\n\/\/!\n\/\/! An incoming HTTP Request is represented as a struct containing\n\/\/! a `Reader` over a `NetworkStream`, which represents the body, headers, a remote\n\/\/! address, an HTTP version, and a `Method` - relatively standard stuff.\n\/\/!\n\/\/! `Request` implements `Reader` itself, meaning that you can ergonomically get\n\/\/! the body out of a `Request` using standard `Reader` methods and helpers.\n\/\/!\n\/\/! #### Response\n\/\/!\n\/\/! An outgoing HTTP Response is also represented as a struct containing a `Writer`\n\/\/! over a `NetworkStream` which represents the Response body in addition to\n\/\/! standard items such as the `StatusCode` and HTTP version. `Response`'s `Writer`\n\/\/! implementation provides a streaming interface for sending data over to the\n\/\/! client.\n\/\/!\n\/\/! One of the traditional problems with representing outgoing HTTP Responses is\n\/\/! tracking the write-status of the Response - have we written the status-line,\n\/\/! the headers, the body, etc.? Hyper tracks this information statically using the\n\/\/! type system and prevents you, using the type system, from writing headers after\n\/\/! you have started writing to the body or vice versa.\n\/\/!\n\/\/! Hyper does this through a phantom type parameter in the definition of Response,\n\/\/! which tracks whether you are allowed to write to the headers or the body. This\n\/\/! phantom type can have two values `Fresh` or `Streaming`, with `Fresh`\n\/\/! indicating that you can write the headers and `Streaming` indicating that you\n\/\/! may write to the body, but not the headers.\n\/\/!\n\/\/! ### Client\n\/\/!\n\/\/! Client-specific functionality, such as `Request` and `Response`\n\/\/! representations, are found in `src\/client`.\n\/\/!\n\/\/! #### Request\n\/\/!\n\/\/! An outgoing HTTP Request is represented as a struct containing a `Writer` over\n\/\/! a `NetworkStream` which represents the Request body in addition to the standard\n\/\/! information such as headers and the request method.\n\/\/!\n\/\/! Outgoing Requests track their write-status in almost exactly the same way as\n\/\/! outgoing HTTP Responses do on the Server, so we will defer to the explanation\n\/\/! in the documentation for sever Response.\n\/\/!\n\/\/! Requests expose an efficient streaming interface instead of a builder pattern,\n\/\/! but they also provide the needed interface for creating a builder pattern over\n\/\/! the API exposed by core Hyper.\n\/\/!\n\/\/! #### Response\n\/\/!\n\/\/! Incoming HTTP Responses are represented as a struct containing a `Reader` over\n\/\/! a `NetworkStream` and contain headers, a status, and an http version. They\n\/\/! implement `Reader` and can be read to get the data out of a `Response`.\n\/\/!\n\nextern crate rustc_serialize as serialize;\nextern crate time;\nextern crate url;\nextern crate openssl;\nextern crate cookie;\nextern crate unicase;\nextern crate httparse;\nextern crate num_cpus;\n\n#[macro_use]\nextern crate log;\n\n#[cfg(test)]\nextern crate test;\n\n\npub use mimewrapper::mime;\npub use url::Url;\npub use client::Client;\npub use error::{HttpResult, HttpError};\npub use method::Method::{Get, Head, Post, Delete};\npub use status::StatusCode::{Ok, BadRequest, NotFound};\npub use server::Server;\n\nmacro_rules! todo(\n    ($($arg:tt)*) => (if cfg!(not(ndebug)) {\n        trace!(\"TODO: {:?}\", format_args!($($arg)*))\n    })\n);\n\nmacro_rules! inspect(\n    ($name:expr, $value:expr) => ({\n        let v = $value;\n        trace!(\"inspect: {:?} = {:?}\", $name, v);\n        v\n    })\n);\n\n#[cfg(test)]\n#[macro_use]\nmod mock;\n#[doc(hidden)]\npub mod buffer;\npub mod client;\npub mod error;\npub mod method;\npub mod header;\npub mod http;\npub mod net;\npub mod server;\npub mod status;\npub mod uri;\npub mod version;\n\n\nmod mimewrapper {\n    \/\/\/ Re-exporting the mime crate, for convenience.\n    extern crate mime;\n}\n\n#[allow(unconditional_recursion)]\nfn _assert_send<T: Send>() {\n    _assert_send::<client::Request<net::Fresh>>();\n    _assert_send::<client::Response>();\n}\n<commit_msg>docs(mainpage): fix typo<commit_after>#![doc(html_root_url = \"https:\/\/hyperium.github.io\/hyper\/hyper\/index.html\")]\n#![feature(core, io, unsafe_destructor, into_cow, convert)]\n#![deny(missing_docs)]\n#![cfg_attr(test, deny(warnings))]\n#![cfg_attr(test, feature(test))]\n\n\/\/! # Hyper\n\/\/!

Client-specific functionality, such as `Request` and `Response`\n\/\/! representations, are found in `src\/client`.\n\/\/!\n\/\/! #### Request\n\/\/!\n\/\/! An outgoing HTTP Request is represented as a struct containing a `Writer` over\n\/\/! a `NetworkStream` which represents the Request body in addition to the standard\n\/\/! information such as headers and the request method.\n\/\/!\n\/\/! Outgoing Requests track their write-status in almost exactly the same way as\n\/\/! outgoing HTTP Responses do on the Server, so we will defer to the explanation\n\/\/! in the documentation for server Response.\n\/\/!\n\/\/! Requests expose an efficient streaming interface instead of a builder pattern,\n\/\/! but they also provide the needed interface for creating a builder pattern over\n\/\/! the API exposed by core Hyper.\n\/\/!\n\/\/! #### Response\n\/\/!\n\/\/! Incoming HTTP Responses are represented as a struct containing a `Reader` over\n\/\/! a `NetworkStream` and contain headers, a status, and an http version. They\n\/\/! implement `Reader` and can be read to get the data out of a `Response`.\n\/\/!\n\nextern crate rustc_serialize as serialize;\nextern crate time;\nextern crate url;\nextern crate openssl;\nextern crate cookie;\nextern crate unicase;\nextern crate httparse;\nextern crate num_cpus;\n\n#[macro_use]\nextern crate log;\n\n#[cfg(test)]\nextern crate test;\n\n\npub use mimewrapper::mime;\npub use url::Url;\npub use client::Client;\npub use error::{HttpResult, HttpError};\npub use method::Method::{Get, Head, Post, Delete};\npub use status::StatusCode::{Ok, BadRequest, NotFound};\npub use server::Server;\n\nmacro_rules! todo(\n    ($($arg:tt)*) => (if cfg!(not(ndebug)) {\n        trace!(\"TODO: {:?}\", format_args!($($arg)*))\n    })\n);\n\nmacro_rules! inspect(\n    ($name:expr, $value:expr) => ({\n        let v = $value;\n        trace!(\"inspect: {:?} = {:?}\", $name, v);\n        v\n    })\n);\n\n#[cfg(test)]\n#[macro_use]\nmod mock;\n#[doc(hidden)]\npub mod buffer;\npub mod client;\npub mod error;\npub mod method;\npub mod header;\npub mod http;\npub mod net;\npub mod server;\npub mod status;\npub mod uri;\npub mod version;\n\n\nmod mimewrapper {\n    \/\/\/ Re-exporting the mime crate, for convenience.\n    extern crate mime;\n}\n\n#[allow(unconditional_recursion)]\nfn _assert_send<T: Send>() {\n    _assert_send::<client::Request<net::Fresh>>();\n    _assert_send::<client::Response>();\n}\n<|endoftext|>"}

Precise Garbage Collector\n\nThe precise GC exposes two functions, gc and\ncleanup_stack_for_failure. The gc function is the entry point to the\ngarbage collector itself. The cleanup_stack_for_failure is the entry\npoint for GC-based cleanup.\n\nPrecise GC depends on changes to LLVM's GC which add support for\nautomatic rooting and addrspace-based metadata marking. Rather than\nexplicitly rooting pointers with LLVM's gcroot intrinsic, the GC\nmerely creates allocas for pointers, and allows an LLVM pass to\nautomatically infer roots based on the allocas present in a function\n(and live at a given location). The compiler communicates the type of\nthe pointer to LLVM by setting the addrspace of the pointer type. The\ncompiler then emits a map from addrspace to tydesc, which LLVM then\nuses to match pointers with their tydesc. The GC reads the metadata\ntable produced by LLVM, and uses it to determine which glue functions\nto call to free objects on their respective heaps.\n\nGC-based cleanup is a replacement for landing pads which relies on the\nGC infrastructure to find pointers on the stack to cleanup. Whereas\nthe normal GC needs to walk task-local heap allocations, the cleanup\ncode needs to walk exchange heap allocations and stack-allocations\nwith destructors.\n\n*\/\n\nimport stackwalk::Word;\nimport libc::size_t;\nimport libc::uintptr_t;\nimport send_map::linear::LinearMap;\n\nexport Word;\nexport gc;\nexport cleanup_stack_for_failure;\n\n\/\/ Mirrors rust_stack.h stk_seg\nstruct StackSegment {\n    let prev: *StackSegment;\n    let next: *StackSegment;\n    let end: uintptr_t;\n    \/\/ And other fields which we don't care about...\n}\n\nextern mod rustrt {\n    fn rust_annihilate_box(ptr: *Word);\n\n    #[rust_stack]\n    fn rust_call_tydesc_glue(root: *Word, tydesc: *Word, field: size_t);\n\n    #[rust_stack]\n    fn rust_gc_metadata() -> *Word;\n\n    fn rust_get_stack_segment() -> *StackSegment;\n}\n\n\/\/ Is fp contained in segment?\nunsafe fn is_frame_in_segment(fp: *Word, segment: *StackSegment) -> bool {\n    let begin: Word = unsafe::reinterpret_cast(&segment);\n    let end: Word = unsafe::reinterpret_cast(&(*segment).end);\n    let frame: Word = unsafe::reinterpret_cast(&fp);\n\n    return begin <= frame && frame <= end;\n}\n\ntype SafePoint = { sp_meta: *Word, fn_meta: *Word };\n\n\/\/ Returns the safe point metadata for the given program counter, if\n\/\/ any.\nunsafe fn is_safe_point(pc: *Word) -> Option<SafePoint> {\n    let module_meta = rustrt::rust_gc_metadata();\n    let num_safe_points_ptr: *u32 = unsafe::reinterpret_cast(&module_meta);\n    let num_safe_points = *num_safe_points_ptr as Word;\n    let safe_points: *Word =\n        ptr::offset(unsafe::reinterpret_cast(&module_meta), 1);\n\n    if ptr::is_null(pc) {\n        return None;\n    }\n\n    \/\/ FIXME (#2997): Use binary rather than linear search.\n    let mut sp = 0 as Word;\n    while sp < num_safe_points {\n        let sp_loc = *ptr::offset(safe_points, sp*3) as *Word;\n        if sp_loc == pc {\n            return Some(\n                {sp_meta: *ptr::offset(safe_points, sp*3 + 1) as *Word,\n                 fn_meta: *ptr::offset(safe_points, sp*3 + 2) as *Word});\n        }\n        sp += 1;\n    }\n    return None;\n}\n\ntype Visitor = fn(root: **Word, tydesc: *Word) -> bool;\n\nunsafe fn bump<T, U>(ptr: *T, count: uint) -> *U {\n    return unsafe::reinterpret_cast(&ptr::offset(ptr, count));\n}\n\nunsafe fn align_to_pointer<T>(ptr: *T) -> *T {\n    let align = sys::min_align_of::<*T>();\n    let ptr: uint = unsafe::reinterpret_cast(&ptr);\n    let ptr = (ptr + (align - 1)) & -align;\n    return unsafe::reinterpret_cast(&ptr);\n}\n\n\/\/ Walks the list of roots for the given safe point, and calls visitor\n\/\/ on each root.\nunsafe fn walk_safe_point(fp: *Word, sp: SafePoint, visitor: Visitor) {\n    let fp_bytes: *u8 = unsafe::reinterpret_cast(&fp);\n    let sp_meta_u32s: *u32 = unsafe::reinterpret_cast(&sp.sp_meta);\n\n    let num_stack_roots = *sp_meta_u32s as uint;\n    let num_reg_roots = *ptr::offset(sp_meta_u32s, 1) as uint;\n\n    let stack_roots: *u32 =\n        unsafe::reinterpret_cast(&ptr::offset(sp_meta_u32s, 2));\n    let reg_roots: *u8 =\n        unsafe::reinterpret_cast(&ptr::offset(stack_roots, num_stack_roots));\n    let addrspaces: *Word =\n        unsafe::reinterpret_cast(&ptr::offset(reg_roots, num_reg_roots));\n    let tydescs: ***Word =\n        unsafe::reinterpret_cast(&ptr::offset(addrspaces, num_stack_roots));\n\n    \/\/ Stack roots\n    let mut sri = 0;\n    while sri < num_stack_roots {\n        if *ptr::offset(addrspaces, sri) >= 1 {\n            let root =\n                ptr::offset(fp_bytes, *ptr::offset(stack_roots, sri) as Word)\n                as **Word;\n            let tydescpp = ptr::offset(tydescs, sri);\n            let tydesc = if ptr::is_not_null(tydescpp) &&\n                ptr::is_not_null(*tydescpp) {\n                **tydescpp\n            } else {\n                ptr::null()\n            };\n            if !visitor(root, tydesc) { return; }\n        }\n        sri += 1;\n    }\n\n    \/\/ Register roots\n    let mut rri = 0;\n    while rri < num_reg_roots {\n        if *ptr::offset(addrspaces, num_stack_roots + rri) == 1 {\n            \/\/ FIXME(#2997): Need to find callee saved registers on the stack.\n        }\n        rri += 1;\n    }\n}\n\ntype Memory = uint;\n\nconst task_local_heap: Memory = 1;\nconst exchange_heap:   Memory = 2;\nconst stack:           Memory = 4;\n\nconst need_cleanup:    Memory = exchange_heap | stack;\n\n\/\/ Find and return the segment containing the given frame pointer.

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`kinds`](kinds\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an\n\/\/! array, lives in the [`vec`](vec\/index.html) module. References to\n\/\/! arrays, `&[T]`, more commonly called \"slices\", are built-in types\n\/\/! for which the [`slice`](slice\/index.html) module defines many\n\/\/! methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](from_str\/index.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`task`](task\/index.html) module contains Rust's threading abstractions,\n\/\/! while [`comm`](comm\/index.html) contains the channel types for message\n\/\/! passing. [`sync`](sync\/index.html) contains further, primitive, shared\n\/\/! memory types, including [`atomics`](sync\/atomics\/index.html).\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UPD, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the [`io`](io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default.

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`kinds`](kinds\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an\n\/\/! array, lives in the [`vec`](vec\/index.html) module. References to\n\/\/! arrays, `&[T]`, more commonly called \"slices\", are built-in types\n\/\/! for which the [`slice`](slice\/index.html) module defines many\n\/\/! methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](from_str\/index.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`task`](task\/index.html) module contains Rust's threading abstractions,\n\/\/! while [`comm`](comm\/index.html) contains the channel types for message\n\/\/! passing. [`sync`](sync\/index.html) contains further, primitive, shared\n\/\/! memory types, including [`atomics`](sync\/atomics\/index.html).\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the [`io`](io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `fail!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\n#![crate_name = \"std\"]\n#![unstable]\n#![comment = \"The Rust standard library\"]\n#![license = \"MIT\/ASL2\"]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"http:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"http:\/\/www.rust-lang.org\/favicon.ico\",\n       html_root_url = \"http:\/\/doc.rust-lang.org\/master\/\",\n       html_playground_url = \"http:\/\/play.rust-lang.org\/\")]\n\n#![feature(macro_rules, globs, managed_boxes, linkage)]\n#![feature(default_type_params, phase, lang_items, unsafe_destructor)]\n\n\/\/ Don't link to std.

A module for working with borrowed data.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/\/ A trait for borrowing data.\n\/\/\/\n\/\/\/ In Rust, it is common to provide different representations of a type for\n\/\/\/ different use cases. For instance, storage location and management for a\n\/\/\/ value can be specifically chosen as appropriate for a particular use via\n\/\/\/ pointer types such as [`Box<T>`] or [`Rc<T>`]. Beyond these generic\n\/\/\/ wrappers that can be used with any type, some types provide optional\n\/\/\/ facets providing potentially costly functionality. An example for such a\n\/\/\/ type is [`String`] which adds the ability to extend a string to the basic\n\/\/\/ [`str`]. This requires keeping additional information unnecessary for a\n\/\/\/ simple, immutable string.\n\/\/\/\n\/\/\/ These types provide access to the underlying data through references\n\/\/\/ to the type of that data. They are said to be ‘borrowed as’ that type.\n\/\/\/ For instance, a [`Box<T>`] can be borrowed as `T` while a [`String`]\n\/\/\/ can be borrowed as `str`.\n\/\/\/\n\/\/\/ Types express that they can be borrowed as some type `T` by implementing\n\/\/\/ `Borrow<T>`, providing a reference to a `T` in the trait’s\n\/\/\/ [`borrow`] method. A type is free to borrow as several different types.\n\/\/\/ If it wishes to mutably borrow as the type – allowing the underlying data\n\/\/\/ to be modified, it can additionally implement [`BorrowMut<T>`].\n\/\/\/\n\/\/\/ Further, when providing implementations for additional traits, it needs\n\/\/\/ to be considered whether they should behave identical to those of the\n\/\/\/ underlying type as a consequence of acting as a representation of that\n\/\/\/ underlying type. Generic code typically uses `Borrow<T>` when it relies\n\/\/\/ on the identical behavior of these additional trait implementations.\n\/\/\/ These traits will likely appear as additional trait bounds.\n\/\/\/\n\/\/\/ If generic code merely needs to work for all types that can\n\/\/\/ provide a reference to related type `T`, it is often better to use\n\/\/\/ [`AsRef<T>`] as more types can safely implement it.\n\/\/\/\n\/\/\/ [`AsRef<T>`]: ..\/..\/std\/convert\/trait.AsRef.html\n\/\/\/ [`BorrowMut<T>`]: trait.BorrowMut.html\n\/\/\/ [`Box<T>`]: ..\/..\/std\/boxed\/struct.Box.html\n\/\/\/ [`Mutex<T>`]: ..\/..\/std\/sync\/struct.Mutex.html\n\/\/\/ [`Rc<T>`]: ..\/..\/std\/rc\/struct.Rc.html\n\/\/\/ [`str`]: ..\/..\/std\/primitive.str.html\n\/\/\/ [`String`]: ..\/..\/std\/string\/struct.String.html\n\/\/\/ [`borrow`]: #tymethod.borrow\n\/\/\/\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ As a data collection, [`HashMap<K, V>`] owns both keys and values. If\n\/\/\/ the key’s actual data is wrapped in a managing type of some kind, it\n\/\/\/ should, however, still be possible to search for a value using a\n\/\/\/ reference to the key’s data. For instance, if the key is a string, then\n\/\/\/ it is likely stored with the hash map as a [`String`], while it should\n\/\/\/ be possible to search using a [`&str`][`str`]. Thus, `insert` needs to\n\/\/\/ operate on a `String` while `get` needs to be able to use a `&str`.\n\/\/\/\n\/\/\/ Slightly simplified, the relevant parts of `HashMap<K, V>` look like\n\/\/\/ this:\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::borrow::Borrow;\n\/\/\/ use std::hash::Hash;\n\/\/\/\n\/\/\/ pub struct HashMap<K, V> {\n\/\/\/     # marker: ::std::marker::PhantomData<(K, V)>,\n\/\/\/     \/\/ fields omitted\n\/\/\/ }\n\/\/\/\n\/\/\/ impl<K, V> HashMap<K, V> {\n\/\/\/     pub fn insert(&self, key: K, value: V) -> Option<V>\n\/\/\/     where K: Hash + Eq\n\/\/\/     {\n\/\/\/         # unimplemented!()\n\/\/\/         \/\/ ...\n\/\/\/     }\n\/\/\/\n\/\/\/     pub fn get<Q>(&self, k: &Q) -> Option<&V>\n\/\/\/     where\n\/\/\/         K: Borrow<Q>,\n\/\/\/         Q: Hash + Eq + ?Sized\n\/\/\/     {\n\/\/\/         # unimplemented!()\n\/\/\/         \/\/ ...\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ The entire hash map is generic over a key type `K`. Because these keys\n\/\/\/ are stored with the hash map, this type has to own the key’s data.\n\/\/\/ When inserting a key-value pair, the map is given such a `K` and needs\n\/\/\/ to find the correct hash bucket and check if the key is already present\n\/\/\/ based on that `K`. It therefore requires `K: Hash + Eq`.\n\/\/\/\n\/\/\/ When searching for a value in the map, however, having to provide a\n\/\/\/ reference to a `K` as the key to search for would require to always\n\/\/\/ create such an owned value. For string keys, this would mean a `String`\n\/\/\/ value needs to be created just for the search for cases where only a\n\/\/\/ `str` is available.\n\/\/\/\n\/\/\/ Instead, the `get` method is generic over the type of the underlying key\n\/\/\/ data, called `Q` in the method signature above. It states that `K`\n\/\/\/ borrows as a `Q` by requiring that `K: Borrow<Q>`. By additionally\n\/\/\/ requiring `Q: Hash + Eq`, it signals the requirement that `K` and `Q`\n\/\/\/ have implementations of the `Hash` and `Eq` traits that produce identical\n\/\/\/ results.\n\/\/\/\n\/\/\/ The implementation of `get` relies in particular on identical\n\/\/\/ implementations of `Hash` by determining the key’s hash bucket by calling\n\/\/\/ `Hash::hash` on the `Q` value even though it inserted the key based on\n\/\/\/ the hash value calculated from the `K` value.\n\/\/\/\n\/\/\/ As a consequence, the hash map breaks if a `K` wrapping a `Q` value\n\/\/\/ produces a different hash than `Q`.

A module for working with borrowed data.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/\/ A trait for borrowing data.\n\/\/\/\n\/\/\/ In Rust, it is common to provide different representations of a type for\n\/\/\/ different use cases. For instance, storage location and management for a\n\/\/\/ value can be specifically chosen as appropriate for a particular use via\n\/\/\/ pointer types such as [`Box<T>`] or [`Rc<T>`]. Beyond these generic\n\/\/\/ wrappers that can be used with any type, some types provide optional\n\/\/\/ facets providing potentially costly functionality. An example for such a\n\/\/\/ type is [`String`] which adds the ability to extend a string to the basic\n\/\/\/ [`str`]. This requires keeping additional information unnecessary for a\n\/\/\/ simple, immutable string.\n\/\/\/\n\/\/\/ These types provide access to the underlying data through references\n\/\/\/ to the type of that data. They are said to be ‘borrowed as’ that type.\n\/\/\/ For instance, a [`Box<T>`] can be borrowed as `T` while a [`String`]\n\/\/\/ can be borrowed as `str`.\n\/\/\/\n\/\/\/ Types express that they can be borrowed as some type `T` by implementing\n\/\/\/ `Borrow<T>`, providing a reference to a `T` in the trait’s\n\/\/\/ [`borrow`] method. A type is free to borrow as several different types.\n\/\/\/ If it wishes to mutably borrow as the type – allowing the underlying data\n\/\/\/ to be modified, it can additionally implement [`BorrowMut<T>`].\n\/\/\/\n\/\/\/ Further, when providing implementations for additional traits, it needs\n\/\/\/ to be considered whether they should behave identical to those of the\n\/\/\/ underlying type as a consequence of acting as a representation of that\n\/\/\/ underlying type. Generic code typically uses `Borrow<T>` when it relies\n\/\/\/ on the identical behavior of these additional trait implementations.\n\/\/\/ These traits will likely appear as additional trait bounds.\n\/\/\/\n\/\/\/ If generic code merely needs to work for all types that can\n\/\/\/ provide a reference to related type `T`, it is often better to use\n\/\/\/ [`AsRef<T>`] as more types can safely implement it.\n\/\/\/\n\/\/\/ [`AsRef<T>`]: ..\/..\/std\/convert\/trait.AsRef.html\n\/\/\/ [`BorrowMut<T>`]: trait.BorrowMut.html\n\/\/\/ [`Box<T>`]: ..\/..\/std\/boxed\/struct.Box.html\n\/\/\/ [`Mutex<T>`]: ..\/..\/std\/sync\/struct.Mutex.html\n\/\/\/ [`Rc<T>`]: ..\/..\/std\/rc\/struct.Rc.html\n\/\/\/ [`str`]: ..\/..\/std\/primitive.str.html\n\/\/\/ [`String`]: ..\/..\/std\/string\/struct.String.html\n\/\/\/ [`borrow`]: #tymethod.borrow\n\/\/\/\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ As a data collection, [`HashMap<K, V>`] owns both keys and values. If\n\/\/\/ the key’s actual data is wrapped in a managing type of some kind, it\n\/\/\/ should, however, still be possible to search for a value using a\n\/\/\/ reference to the key’s data. For instance, if the key is a string, then\n\/\/\/ it is likely stored with the hash map as a [`String`], while it should\n\/\/\/ be possible to search using a [`&str`][`str`]. Thus, `insert` needs to\n\/\/\/ operate on a `String` while `get` needs to be able to use a `&str`.\n\/\/\/\n\/\/\/ Slightly simplified, the relevant parts of `HashMap<K, V>` look like\n\/\/\/ this:\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::borrow::Borrow;\n\/\/\/ use std::hash::Hash;\n\/\/\/\n\/\/\/ pub struct HashMap<K, V> {\n\/\/\/     # marker: ::std::marker::PhantomData<(K, V)>,\n\/\/\/     \/\/ fields omitted\n\/\/\/ }\n\/\/\/\n\/\/\/ impl<K, V> HashMap<K, V> {\n\/\/\/     pub fn insert(&self, key: K, value: V) -> Option<V>\n\/\/\/     where K: Hash + Eq\n\/\/\/     {\n\/\/\/         # unimplemented!()\n\/\/\/         \/\/ ...\n\/\/\/     }\n\/\/\/\n\/\/\/     pub fn get<Q>(&self, k: &Q) -> Option<&V>\n\/\/\/     where\n\/\/\/         K: Borrow<Q>,\n\/\/\/         Q: Hash + Eq + ?Sized\n\/\/\/     {\n\/\/\/         # unimplemented!()\n\/\/\/         \/\/ ...\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ The entire hash map is generic over a key type `K`. Because these keys\n\/\/\/ are stored with the hash map, this type has to own the key’s data.\n\/\/\/ When inserting a key-value pair, the map is given such a `K` and needs\n\/\/\/ to find the correct hash bucket and check if the key is already present\n\/\/\/ based on that `K`. It therefore requires `K: Hash + Eq`.\n\/\/\/\n\/\/\/ When searching for a value in the map, however, having to provide a\n\/\/\/ reference to a `K` as the key to search for would require to always\n\/\/\/ create such an owned value. For string keys, this would mean a `String`\n\/\/\/ value needs to be created just for the search for cases where only a\n\/\/\/ `str` is available.\n\/\/\/\n\/\/\/ Instead, the `get` method is generic over the type of the underlying key\n\/\/\/ data, called `Q` in the method signature above. It states that `K`\n\/\/\/ borrows as a `Q` by requiring that `K: Borrow<Q>`. By additionally\n\/\/\/ requiring `Q: Hash + Eq`, it signals the requirement that `K` and `Q`\n\/\/\/ have implementations of the `Hash` and `Eq` traits that produce identical\n\/\/\/ results.\n\/\/\/\n\/\/\/ The implementation of `get` relies in particular on identical\n\/\/\/ implementations of `Hash` by determining the key’s hash bucket by calling\n\/\/\/ `Hash::hash` on the `Q` value even though it inserted the key based on\n\/\/\/ the hash value calculated from the `K` value.\n\/\/\/\n\/\/\/ As a consequence, the hash map breaks if a `K` wrapping a `Q` value\n\/\/\/ produces a different hash than `Q`. For instance, imagine you have a\n\/\/\/ type that wraps a string but compares ASCII letters ignoring their case:\n\/\/\/\n\/\/\/ ```\n\/\/\/ pub struct CaseInsensitiveString(String);\n\/\/\/\n\/\/\/ impl PartialEq for CaseInsensitiveString {\n\/\/\/     fn eq(&self, other: &Self) -> bool {\n\/\/\/         self.0.eq_ignore_ascii_case(&other.0)\n\/\/\/     }\n\/\/\/ }\n\/\/\/\n\/\/\/ impl Eq for CaseInsensitiveString { }\n\/\/\/ ```\n\/\/\/\n\/\/\/ Because two equal values need to produce the same hash value, the\n\/\/\/ implementation of `Hash` needs to ignore ASCII case, too:\n\/\/\/\n\/\/\/ ```\n\/\/\/ # use std::hash::{Hash, Hasher};\n\/\/\/ # pub struct CaseInsensitiveString(String);\n\/\/\/ impl Hash for CaseInsensitiveString {\n\/\/\/     fn hash<H: Hasher>(&self, state: &mut H) {\n\/\/\/         for c in self.0.as_bytes() {\n\/\/\/             c.to_ascii_lowercase().hash(state)\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ Can `CaseInsensitiveString` implement `Borrow<str>`? It certainly can\n\/\/\/ provide a reference to a string slice via its contained owned string.\n\/\/\/ But because its `Hash` implementation differs, it behaves differently\n\/\/\/ from `str` and therefore must not, in fact, implement `Borrow<str>`.\n\/\/\/ If it wants to allow others access to the underlying `str`, it can do\n\/\/\/ that via `AsRef<str>` which doesn’t carry any extra requirements.\n\/\/\/\n\/\/\/ [`Hash`]: ..\/..\/std\/hash\/trait.Hash.html\n\/\/\/ [`HashMap<K, V>`]: ..\/..\/std\/collections\/struct.HashMap.html\n\/\/\/ [`String`]: ..\/..\/std\/string\/struct.String.html\n\/\/\/ [`str`]: ..\/..\/std\/primitive.str.html\n\/\/\/\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait Borrow<Borrowed: ?Sized> {\n    \/\/\/ Immutably borrows from an owned value.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ use std::borrow::Borrow;\n    \/\/\/\n    \/\/\/ fn check<T: Borrow<str>>(s: T) {\n    \/\/\/     assert_eq!(\"Hello\", s.borrow());\n    \/\/\/ }\n    \/\/\/\n    \/\/\/ let s = \"Hello\".to_string();\n    \/\/\/\n    \/\/\/ check(s);\n    \/\/\/\n    \/\/\/ let s = \"Hello\";\n    \/\/\/\n    \/\/\/ check(s);\n    \/\/\/ ```\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn borrow(&self) -> &Borrowed;\n}\n\n\/\/\/ A trait for mutably borrowing data.\n\/\/\/\n\/\/\/ As a companion to [`Borrow<T>`] this trait allows a type to borrow as\n\/\/\/ an underlying type by providing a mutable reference.

In safe code\nit is impossible to create an instance of an empty type, so empty match\nexpressions are almost never desired.  This error is typically fixed by adding\none or more cases to the match expression.\n\nAn example of an empty type is `enum Empty { }`.\n\"##,\n\nE0003: r##\"\nNot-a-Number (NaN) values cannot be compared for equality and hence can never\nmatch the input to a match expression. To match against NaN values, you should\ninstead use the `is_nan` method in a guard, as in: x if x.is_nan() => ...\n\"##,\n\nE0004: r##\"\nThis error indicates that the compiler cannot guarantee a matching pattern for\none or more possible inputs to a match expression. Guaranteed matches are\nrequired in order to assign values to match expressions, or alternatively,\ndetermine the flow of execution.\n\nIf you encounter this error you must alter your patterns so that every possible\nvalue of the input type is matched. For types with a small number of variants\n(like enums) you should probably cover all cases explicitly.

To access a single element of a tuple one can use the following\n\/\/! methods:\n\/\/!\n\/\/! * `valN` - returns a value of _N_-th element\n\/\/! * `refN` - returns a reference to _N_-th element\n\/\/! * `mutN` - returns a mutable reference to _N_-th element\n\/\/!\n\/\/! Indexing starts from zero, so `val0` returns first value, `val1`\n\/\/! returns second value, and so on. In general, a tuple with _S_\n\/\/! elements provides aforementioned methods suffixed with numbers\n\/\/! from `0` to `S-1`. Traits which contain these methods are\n\/\/! implemented for tuples with up to 12 elements.\n\/\/!\n\/\/! If every type inside a tuple implements one of the following\n\/\/! traits, then a tuple itself also implements it.\n\/\/!\n\/\/! * `Clone`\n\/\/! * `PartialEq`\n\/\/! * `Eq`\n\/\/! * `PartialOrd`\n\/\/!

To access a single element of a tuple one can use the following\n\/\/! methods:\n\/\/!\n\/\/! * `valN` - returns a value of _N_-th element\n\/\/! * `refN` - returns a reference to _N_-th element\n\/\/! * `mutN` - returns a mutable reference to _N_-th element\n\/\/!\n\/\/! Indexing starts from zero, so `val0` returns first value, `val1`\n\/\/! returns second value, and so on. In general, a tuple with _S_\n\/\/! elements provides aforementioned methods suffixed with numbers\n\/\/! from `0` to `S-1`. Traits which contain these methods are\n\/\/! implemented for tuples with up to 12 elements.\n\/\/!\n\/\/! If every type inside a tuple implements one of the following\n\/\/! traits, then a tuple itself also implements it.\n\/\/!\n\/\/! * `Clone`\n\/\/! * `PartialEq`\n\/\/! * `Eq`\n\/\/! * `PartialOrd`\n\/\/! * `Ord`\n\/\/! * `Default`\n\n#![stable]\n\nuse clone::Clone;\nuse cmp::*;\nuse cmp::Ordering::*;\nuse default::Default;\nuse option::Option;\nuse option::Option::Some;\n\n\/\/ FIXME(#19630) Remove this work-around\nmacro_rules!

Therefore, recursive use is not\n * permitted.  That is, while iterating through a vector, you cannot\n * access the vector in any other way or else the program will fail.  If\n * you wish, you can use the `swap()` method to gain access to the raw\n * vector and transform it or use it any way you like.  Eventually, we\n * may permit read-only access during iteration or other use.\n *\n * # WARNING\n *\n * For maximum performance, this type is implemented using some rather\n * unsafe code.  In particular, this innocent looking `~[mut A]` pointer\n * *may be null!*  Therefore, it is important you not reach into the\n * data structure manually but instead use the provided extensions.\n *\n * The reason that I did not use an unsafe pointer in the structure\n * itself is that I wanted to ensure that the vector would be freed when\n * the dvec is dropped.  The reason that I did not use an `Option<T>`\n * instead of a nullable pointer is that I found experimentally that it\n * becomes approximately 50% slower. This can probably be improved\n * through optimization.  You can run your own experiments using\n * `src\/test\/bench\/vec-append.rs`. My own tests found that using null\n * pointers achieved about 103 million pushes\/second.

Therefore, recursive use is not\n * permitted.  That is, while iterating through a vector, you cannot\n * access the vector in any other way or else the program will fail.  If\n * you wish, you can use the `swap()` method to gain access to the raw\n * vector and transform it or use it any way you like.  Eventually, we\n * may permit read-only access during iteration or other use.\n *\n * # WARNING\n *\n * For maximum performance, this type is implemented using some rather\n * unsafe code.  In particular, this innocent looking `~[mut A]` pointer\n * *may be null!*  Therefore, it is important you not reach into the\n * data structure manually but instead use the provided extensions.\n *\n * The reason that I did not use an unsafe pointer in the structure\n * itself is that I wanted to ensure that the vector would be freed when\n * the dvec is dropped.  The reason that I did not use an `Option<T>`\n * instead of a nullable pointer is that I found experimentally that it\n * becomes approximately 50% slower. This can probably be improved\n * through optimization.  You can run your own experiments using\n * `src\/test\/bench\/vec-append.rs`. My own tests found that using null\n * pointers achieved about 103 million pushes\/second.

Functions with the\n\/\/ #[no_stack_check] attribute have the same prologue as regular C functions\n\/\/ compiled with GCC or Clang and therefore are better handled by GDB. As a\n\/\/ consequence, and as opposed to regular Rust functions, we can set the\n\/\/ breakpoints via the function name (and don't have to fall back on using line\n\/\/ numbers). For LLDB this shouldn't make a difference because it can handle\n\/\/ both cases.\n\n\/\/ compile-flags:-g\n\n\/\/ === GDB TESTS

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`marker`](marker\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an\n\/\/! array, lives in the [`vec`](vec\/index.html) module. References to\n\/\/! arrays, `&[T]`, more commonly called \"slices\", are built-in types\n\/\/! for which the [`slice`](slice\/index.html) module defines many\n\/\/! methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading abstractions.\n\/\/! [`sync`](sync\/index.html) contains further, primitive, shared memory types,\n\/\/! including [`atomic`](sync\/atomic\/index.html), and [`mpsc`](sync\/mpsc\/index.html),\n\/\/! which contains the channel types for message passing.\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the\n\/\/! [`old_io`](old_io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\/\/ Do not remove on snapshot creation.

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`marker`](marker\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! for which the [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes modules for interoperating with the\n\/\/! C language: [`c_str`](c_str\/index.html) and\n\/\/! [`c_vec`](c_vec\/index.html).\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading abstractions.\n\/\/! [`sync`](sync\/index.html) contains further, primitive, shared memory types,\n\/\/! including [`atomic`](sync\/atomic\/index.html), and [`mpsc`](sync\/mpsc\/index.html),\n\/\/! which contains the channel types for message passing.\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the\n\/\/! [`old_io`](old_io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\/\/ Do not remove on snapshot creation. Needed for bootstrap.

This is typically derived via a `#[dom_struct]` (implies `#[jstraceable]`) annotation.\n\/\/!    Non-JS-managed types have an empty inline `trace()` method,\n\/\/!    achieved via `no_jsmanaged_fields!` or similar.\n\/\/! 3. For all fields, `Foo::trace()`\n\/\/!    calls `trace()` on the field.\n\/\/!    For example, for fields of type `JS<T>`, `JS<T>::trace()` calls\n\/\/!    `trace_reflector()`.\n\/\/! 4. `trace_reflector()` calls `trace_object()` with the `JSObject` for the\n\/\/!    reflector.\n\/\/! 5. `trace_object()` calls `JS_CallTracer()` to notify the GC, which will\n\/\/!    add the object to the graph, and will trace that object as well.\n\/\/! 6. When the GC finishes tracing, it [`finalizes`](..\/index.html#destruction)\n\/\/!    any reflectors that were not reachable.\n\/\/!\n\/\/! The `no_jsmanaged_fields!()` macro adds an empty implementation of `JSTraceable` to\n\/\/! a datatype.\n\nuse dom::bindings::js::JS;\nuse dom::bindings::refcounted::Trusted;\nuse

The lifetime of DOM objects is managed by the SpiderMonkey Garbage\n\/\/! Collector. A rooted DOM object implementing the interface `Foo` is traced\n\/\/! as follows:\n\/\/!\n\/\/! 1. The GC calls `_trace` defined in `FooBinding` during the marking\n\/\/!    phase. (This happens through `JSClass.trace` for non-proxy bindings, and\n\/\/!    through `ProxyTraps.trace` otherwise.)\n\/\/! 2. `_trace` calls `Foo::trace()` (an implementation of `JSTraceable`).\n\/\/!    This is typically derived via a `#[dom_struct]` (implies `#[jstraceable]`) annotation.\n\/\/!    Non-JS-managed types have an empty inline `trace()` method,\n\/\/!    achieved via `no_jsmanaged_fields!` or similar.\n\/\/! 3. For all fields, `Foo::trace()`\n\/\/!    calls `trace()` on the field.\n\/\/!    For example, for fields of type `JS<T>`, `JS<T>::trace()` calls\n\/\/!    `trace_reflector()`.\n\/\/! 4. `trace_reflector()` calls `trace_object()` with the `JSObject` for the\n\/\/!    reflector.\n\/\/! 5. `trace_object()` calls `JS_CallTracer()` to notify the GC, which will\n\/\/!    add the object to the graph, and will trace that object as well.\n\/\/! 6. When the GC finishes tracing, it [`finalizes`](..\/index.html#destruction)\n\/\/!    any reflectors that were not reachable.\n\/\/!\n\/\/! The `no_jsmanaged_fields!()` macro adds an empty implementation of `JSTraceable` to\n\/\/! a datatype.\n\nuse dom::bindings::js::JS;\nuse dom::bindings::refcounted::Trusted;\nuse

The methods of this module shouldn't necessarily be used directly,\nbut rather through the logging macros defined.\n\nThere are five macros that the logging subsystem uses:\n\n* `log!(level, ...)` - the generic logging macro, takes a level as a u32 and any\n                       related `format!` arguments\n* `debug!(...)` - a macro hard-wired to the log level of `DEBUG`\n* `info!(...)` - a macro hard-wired to the log level of `INFO`\n* `warn!(...)` - a macro hard-wired to the log level of `WARN`\n* `error!(...)` - a macro hard-wired to the log level of `ERROR`\n\nAll of these macros use the same style of syntax as the `format!` syntax\nextension. Details about the syntax can be found in the documentation of\n`std::fmt` along with the Rust tutorial\/manual.\n\nIf you want to check at runtime if a given logging level is enabled (e.g. if the\ninformation you would want to log is expensive to produce), you can use the\nfollowing macro:\n\n* `log_enabled!(level)` - returns true if logging of the given level is enabled\n\n## Enabling logging\n\nLog levels are controlled on a per-module basis, and by default all logging is\ndisabled except for `error!` (a log level of 1). Logging is controlled via the\n`RUST_LOG` environment variable. The value of this environment variable is a\ncomma-separated list of logging directives. A logging directive is of the form:\n\n```\npath::to::module=log_level\n```\n\nThe path to the module is rooted in the name of the crate it was compiled for,\nso if your program is contained in a file `hello.rs`, for example, to turn on\nlogging for this file you would use a value of `RUST_LOG=hello`. Furthermore,\nthis path is a prefix-search, so all modules nested in the specified module will\nalso have logging enabled.\n\nThe actual `log_level` is optional to specify. If omitted, all logging will be\nenabled. If specified, the it must be either a numeric in the range of 1-255, or\nit must be one of the strings `debug`, `error`, `info`, or `warn`. If a numeric\nis specified, then all logging less than or equal to that numeral is enabled.\nFor example, if logging level 3 is active, error, warn, and info logs will be\nprinted, but debug will be omitted.\n\nAs the log level for a module is optional, the module to enable logging for is\nalso optional. If only a `log_level` is provided, then the global log level for\nall modules is set to this value.\n\nSome examples of valid values of `RUST_LOG` are:\n\n```\nhello                \/\/ turns on all logging for the 'hello' module\ninfo                 \/\/ turns on all info logging\nhello=debug          \/\/ turns on debug logging for 'hello'\nhello=3              \/\/ turns on info logging for 'hello'\nhello,std::hashmap   \/\/ turns on hello, and std's hashmap logging\nerror,hello=warn     \/\/ turn on global error logging and also warn for hello\n```\n\n## Performance and Side Effects\n\nEach of these macros will expand to code similar to:\n\n```rust,ignore\nif log_level <= my_module_log_level() {\n    ::std::logging::log(log_level, format!(...));\n}\n```\n\nWhat this means is that each of these macros are very cheap at runtime if\nthey're turned off (just a load and an integer comparison). This also means that\nif logging is disabled, none of the components of the log will be executed.\n\n## Useful Values\n\nFor convenience, if a value of `::help` is set for `RUST_LOG`, a program will\nstart, print out all modules registered for logging, and then exit.\n\n*\/\n\nuse fmt;\nuse option::*;\nuse rt::local::Local;\nuse rt::logging::{Logger, StdErrLogger};\nuse rt::task::Task;\n\n\/\/\/ Debug log level\npub static DEBUG: u32 = 4;\n\/\/\/ Info log level\npub static INFO: u32 = 3;\n\/\/\/ Warn log level\npub static WARN: u32 = 2;\n\/\/\/ Error log level\npub static ERROR: u32 = 1;\n\n\/\/\/ This function is called directly by the compiler when using the logging\n\/\/\/ macros.

Here's what's interesting, for the purposes of this test:\n\/\/\n\/\/  1. The test focuses on expression nesting, because interactions between different expression\n\/\/     types are harder to test manually than single expression types in isolation.\n\/\/\n\/\/  2. The test only considers expressions of at most two nontrivial nodes.  So it will check `x +\n\/\/     x` and `x + (x - x)` but not `(x * x) + (x - x)`.  The assumption here is that the correct\n\/\/     handling of an expression might depend on the expression's parent, but doesn't depend on its\n\/\/     siblings or any more distant ancestors.\n\/\/\n\/\/ 3. The test only checks certain expression kinds.  The assumption is that similar expression\n\/\/    types, such as `if` and `while` or `+` and `-`,  will be handled identically in the printer\n\/\/    and parser.  So if all combinations of exprs involving `if` work correctly, then combinations\n\/\/    using `while`, `if let`, and so on will likely work as well.\n\n\n#![feature(rustc_private)]\n\nextern crate syntax;\n\nuse syntax::ast::*;\nuse syntax::codemap::{Spanned, DUMMY_SP};\nuse syntax::codemap::FilePathMapping;\nuse syntax::fold::{self, Folder};\nuse syntax::parse::{self, ParseSess};\nuse syntax::print::pprust;\nuse syntax::ptr::P;\nuse syntax::util::ThinVec;\n\n\nfn parse_expr(ps: &ParseSess, src: &str) -> P<Expr> {\n    let mut p = parse::new_parser_from_source_str(ps,\n                                                  \"<expr>\".to_owned(),\n                                                  src.to_owned());\n    p.parse_expr().unwrap()\n}\n\n\n\/\/ Helper functions for building exprs\nfn expr(kind: ExprKind) -> P<Expr> {\n    P(Expr {\n        id: DUMMY_NODE_ID,\n        node: kind,\n        span: DUMMY_SP,\n        attrs: ThinVec::new(),\n    })\n}\n\nfn make_x() -> P<Expr> {\n    let seg = PathSegment {\n        identifier: Ident::from_str(\"x\"),\n        span: DUMMY_SP,\n        parameters: None,\n    };\n    let path = Path {\n        span: DUMMY_SP,\n        segments: vec![seg],\n    };\n    expr(ExprKind::Path(None, path))\n}\n\n\/\/\/ Iterate over exprs of depth up to `depth`.

A 'lint' check is a kind of miscellaneous constraint that a user _might_\n\/\/! want to enforce, but might reasonably want to permit as well, on a\n\/\/! module-by-module basis. They contrast with static constraints enforced by\n\/\/! other phases of the compiler, which are generally required to hold in order\n\/\/! to compile the program at all.\n\/\/!\n\/\/! Most lints can be written as `LintPass` instances. These run just before\n\/\/! translation to LLVM bytecode. The `LintPass`es built into rustc are defined\n\/\/! within `builtin.rs`, which has further comments on how to add such a lint.\n\/\/! rustc can also load user-defined lint plugins via the plugin mechanism.\n\/\/!\n\/\/! Some of rustc's lints are defined elsewhere in the compiler and work by\n\/\/! calling `add_lint()` on the overall `Session` object. This works when\n\/\/! it happens before the main lint pass, which emits the lints stored by\n\/\/! `add_lint()`. To emit lints after the main lint pass (from trans, for\n\/\/! example) requires more effort. See `emit_lint` and `GatherNodeLevels`\n\/\/! in `context.rs`.\n\npub use self::Level::*;\npub use self::LintSource::*;\n\nuse std::hash;\nuse std::ascii::AsciiExt;\nuse syntax::codemap::Span;\nuse rustc_front::visit::FnKind;\nuse syntax::visit as ast_visit;\nuse syntax::ast;\nuse rustc_front::hir;\n\npub use lint::context::{LateContext, EarlyContext, LintContext, LintStore,\n                        raw_emit_lint, check_crate, check_ast_crate, gather_attrs,\n                        GatherNodeLevels};\n\n\/\/\/ Specification of a single lint.\n#[derive(Copy, Clone, Debug)]\npub struct Lint {\n    \/\/\/ A string identifier for the lint.\n    \/\/\/\n    \/\/\/ This identifies the lint in attributes and in command-line arguments.\n    \/\/\/ In those contexts it is always lowercase, but this field is compared\n    \/\/\/ in a way which is case-insensitive for ASCII characters.

A 'lint' check is a kind of miscellaneous constraint that a user _might_\n\/\/! want to enforce, but might reasonably want to permit as well, on a\n\/\/! module-by-module basis. They contrast with static constraints enforced by\n\/\/! other phases of the compiler, which are generally required to hold in order\n\/\/! to compile the program at all.\n\/\/!\n\/\/! Most lints can be written as `LintPass` instances. These run just before\n\/\/! translation to LLVM bytecode. The `LintPass`es built into rustc are defined\n\/\/! within `builtin.rs`, which has further comments on how to add such a lint.\n\/\/! rustc can also load user-defined lint plugins via the plugin mechanism.\n\/\/!\n\/\/! Some of rustc's lints are defined elsewhere in the compiler and work by\n\/\/! calling `add_lint()` on the overall `Session` object. This works when\n\/\/! it happens before the main lint pass, which emits the lints stored by\n\/\/! `add_lint()`. To emit lints after the main lint pass (from trans, for\n\/\/! example) requires more effort. See `emit_lint` and `GatherNodeLevels`\n\/\/! in `context.rs`.\n\npub use self::Level::*;\npub use self::LintSource::*;\n\nuse std::hash;\nuse std::ascii::AsciiExt;\nuse syntax::codemap::Span;\nuse rustc_front::visit::FnKind;\nuse syntax::visit as ast_visit;\nuse syntax::ast;\nuse rustc_front::hir;\n\npub use lint::context::{LateContext, EarlyContext, LintContext, LintStore,\n                        raw_emit_lint, check_crate, check_ast_crate, gather_attrs,\n                        GatherNodeLevels};\n\n\/\/\/ Specification of a single lint.\n#[derive(Copy, Clone, Debug)]\npub struct Lint {\n    \/\/\/ A string identifier for the lint.\n    \/\/\/\n    \/\/\/ This identifies the lint in attributes and in command-line arguments.\n    \/\/\/ In those contexts it is always lowercase, but this field is compared\n    \/\/\/ in a way which is case-insensitive for ASCII characters.

The core problem was that the type\n\/\/ folding code was over-zealously passing back all lifetimes when\n\/\/ doing region-folding, when really all clients of the region-folding\n\/\/ case only want to see FREE lifetime variables, not bound ones.\n\npub fn main() {\n    fn explicit() {\n        fn test(_x: Option<|f: <'a> |g: &'a int||>) {}\n        test(Some(|_f: <'a> |g: &'a int|| {}));\n    }\n\n    \/\/ The code below is shorthand for the code above (and more likely\n    \/\/ to represent what one encounters in practice).\n    fn implicit() {\n        fn test(_x: Option<|f:      |g: &   int||>) {}\n        test(Some(|_f:      |g: &   int|| {}));\n    }\n\n    explicit();\n    implicit();\n}\n<|endoftext|>"}

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/ FIXME: talk about offset, copy_memory, copy_nonoverlapping_memory\n\n\/\/! Operations on unsafe pointers, `*const T`, and `*mut T`.\n\/\/!\n\/\/! Working with unsafe pointers in Rust is uncommon,\n\/\/! typically limited to a few patterns.\n\/\/!\n\/\/! Use the [`null` function](fn.null.html) to create null pointers,\n\/\/! the [`is_null`](trait.RawPtr.html#tymethod.is_null)\n\/\/! and [`is_not_null`](trait.RawPtr.html#method.is_not_null)\n\/\/! methods of the [`RawPtr` trait](trait.RawPtr.html) to check for null.\n\/\/! The `RawPtr` trait is imported by the prelude, so `is_null` etc.\n\/\/! work everywhere. The `RawPtr` also defines the `offset` method,\n\/\/! for pointer math.\n\/\/!\n\/\/! # Common ways to create unsafe pointers\n\/\/!\n\/\/! ## 1. Coerce a reference (`&T`) or mutable reference (`&mut T`).\n\/\/!\n\/\/! ```\n\/\/! let my_num: int = 10;\n\/\/! let my_num_ptr: *const int = &my_num;\n\/\/! let mut my_speed: int = 88;\n\/\/! let my_speed_ptr: *mut int = &mut my_speed;\n\/\/! ```\n\/\/!\n\/\/! This does not take ownership of the original allocation\n\/\/! and requires no resource management later,\n\/\/! but you must not use the pointer after its lifetime.\n\/\/!\n\/\/! ## 2. Transmute an owned box (`Box<T>`).\n\/\/!\n\/\/! The `transmute` function takes, by value, whatever it's given\n\/\/! and returns it as whatever type is requested, as long as the\n\/\/! types are the same size. Because `Box<T>` and `*mut T` have the same\n\/\/! representation they can be trivially,\n\/\/! though unsafely, transformed from one type to the other.\n\/\/!\n\/\/! ```\n\/\/! use std::mem;\n\/\/!\n\/\/! unsafe {\n\/\/!     let my_num: Box<int> = box 10;\n\/\/!     let my_num: *const int = mem::transmute(my_num);\n\/\/!     let my_speed: Box<int> = box 88;\n\/\/!     let my_speed: *mut int = mem::transmute(my_speed);\n\/\/!\n\/\/!     \/\/ By taking ownership of the original `Box<T>` though\n\/\/!     \/\/ we are obligated to transmute it back later to be destroyed.\n\/\/!     drop(mem::transmute::<_, Box<int>>(my_speed));\n\/\/!     drop(mem::transmute::<_, Box<int>>(my_num));\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! Note that here the call to `drop` is for clarity - it indicates\n\/\/! that we are done with the given value and it should be destroyed.\n\/\/!\n\/\/! ## 3. Get it from C.\n\/\/!\n\/\/! ```\n\/\/! extern crate libc;\n\/\/!\n\/\/! use std::mem;\n\/\/!\n\/\/! fn main() {\n\/\/!     unsafe {\n\/\/!         let my_num: *mut int = libc::malloc(mem::size_of::<int>() as libc::size_t) as *mut int;\n\/\/!         if my_num.is_null() {\n\/\/!             panic!(\"failed to allocate memory\");\n\/\/!         }\n\/\/!         libc::free(my_num as *mut libc::c_void);\n\/\/!     }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! Usually you wouldn't literally use `malloc` and `free` from Rust,\n\/\/! but C APIs hand out a lot of pointers generally, so are a common source\n\/\/! of unsafe pointers in Rust.\n\nuse mem;\nuse clone::Clone;\nuse intrinsics;\nuse option::Option;\nuse option::Option::{Some, None};\n\nuse cmp::{PartialEq, Eq, PartialOrd, Equiv};\nuse cmp::Ordering;\nuse cmp::Ordering::{Less, Equal, Greater};\n\npub use intrinsics::copy_memory;\npub use intrinsics::copy_nonoverlapping_memory;\npub use intrinsics::set_memory;\n\n\/\/\/ Create a null pointer.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::ptr;\n\/\/\/\n\/\/\/ let p: *const int = ptr::null();\n\/\/\/ assert!(p.is_null());\n\/\/\/ ```\n#[inline]\n#[unstable = \"may need a different name after pending changes to pointer types\"]\npub fn null<T>() -> *const T { 0 as *const T }\n\n\/\/\/ Create an unsafe mutable null pointer.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::ptr;\n\/\/\/\n\/\/\/ let p: *mut int = ptr::null_mut();\n\/\/\/ assert!(p.is_null());\n\/\/\/ ```\n#[inline]\n#[unstable = \"may need a different name after pending changes to pointer types\"]\npub fn null_mut<T>() -> *mut T { 0 as *mut T }\n\n\/\/\/ Zeroes out `count * size_of::<T>` bytes of memory at `dst`\n#[inline]\n#[experimental = \"uncertain about naming and semantics\"]\n#[allow(experimental)]\npub unsafe fn zero_memory<T>(dst: *mut T, count: uint) {\n    set_memory(dst, 0, count);\n}\n\n\/\/\/ Swap the values at two mutable locations of the same type, without\n\/\/\/ deinitialising either.

Operations on unsafe pointers, `*const T`, and `*mut T`.\n\/\/!\n\/\/! Working with unsafe pointers in Rust is uncommon,\n\/\/! typically limited to a few patterns.\n\/\/!\n\/\/! Use the [`null` function](fn.null.html) to create null pointers,\n\/\/! the [`is_null`](trait.RawPtr.html#tymethod.is_null)\n\/\/! and [`is_not_null`](trait.RawPtr.html#method.is_not_null)\n\/\/! methods of the [`RawPtr` trait](trait.RawPtr.html) to check for null.\n\/\/! The `RawPtr` trait is imported by the prelude, so `is_null` etc.\n\/\/! work everywhere. The `RawPtr` also defines the `offset` method,\n\/\/! for pointer math.\n\/\/!\n\/\/! # Common ways to create unsafe pointers\n\/\/!\n\/\/! ## 1. Coerce a reference (`&T`) or mutable reference (`&mut T`).\n\/\/!\n\/\/! ```\n\/\/! let my_num: int = 10;\n\/\/! let my_num_ptr: *const int = &my_num;\n\/\/! let mut my_speed: int = 88;\n\/\/! let my_speed_ptr: *mut int = &mut my_speed;\n\/\/! ```\n\/\/!\n\/\/! This does not take ownership of the original allocation\n\/\/! and requires no resource management later,\n\/\/! but you must not use the pointer after its lifetime.\n\/\/!\n\/\/! ## 2. Transmute an owned box (`Box<T>`).\n\/\/!\n\/\/! The `transmute` function takes, by value, whatever it's given\n\/\/! and returns it as whatever type is requested, as long as the\n\/\/! types are the same size. Because `Box<T>` and `*mut T` have the same\n\/\/! representation they can be trivially,\n\/\/! though unsafely, transformed from one type to the other.\n\/\/!\n\/\/! ```\n\/\/! use std::mem;\n\/\/!\n\/\/! unsafe {\n\/\/!     let my_num: Box<int> = box 10;\n\/\/!     let my_num: *const int = mem::transmute(my_num);\n\/\/!     let my_speed: Box<int> = box 88;\n\/\/!     let my_speed: *mut int = mem::transmute(my_speed);\n\/\/!\n\/\/!     \/\/ By taking ownership of the original `Box<T>` though\n\/\/!     \/\/ we are obligated to transmute it back later to be destroyed.\n\/\/!     drop(mem::transmute::<_, Box<int>>(my_speed));\n\/\/!     drop(mem::transmute::<_, Box<int>>(my_num));\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! Note that here the call to `drop` is for clarity - it indicates\n\/\/! that we are done with the given value and it should be destroyed.\n\/\/!\n\/\/! ## 3. Get it from C.\n\/\/!\n\/\/! ```\n\/\/! extern crate libc;\n\/\/!\n\/\/! use std::mem;\n\/\/!\n\/\/! fn main() {\n\/\/!     unsafe {\n\/\/!         let my_num: *mut int = libc::malloc(mem::size_of::<int>() as libc::size_t) as *mut int;\n\/\/!         if my_num.is_null() {\n\/\/!             panic!(\"failed to allocate memory\");\n\/\/!         }\n\/\/!         libc::free(my_num as *mut libc::c_void);\n\/\/!     }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! Usually you wouldn't literally use `malloc` and `free` from Rust,\n\/\/! but C APIs hand out a lot of pointers generally, so are a common source\n\/\/! of unsafe pointers in Rust.\n\nuse mem;\nuse clone::Clone;\nuse intrinsics;\nuse option::Option;\nuse option::Option::{Some, None};\n\nuse cmp::{PartialEq, Eq, Ord, PartialOrd, Equiv};\nuse cmp::Ordering;\nuse cmp::Ordering::{Less, Equal, Greater};\n\npub use intrinsics::copy_memory;\npub use intrinsics::copy_nonoverlapping_memory;\npub use intrinsics::set_memory;\n\n\/\/\/ Create a null pointer.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::ptr;\n\/\/\/\n\/\/\/ let p: *const int = ptr::null();\n\/\/\/ assert!(p.is_null());\n\/\/\/ ```\n#[inline]\n#[unstable = \"may need a different name after pending changes to pointer types\"]\npub fn null<T>() -> *const T { 0 as *const T }\n\n\/\/\/ Create an unsafe mutable null pointer.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::ptr;\n\/\/\/\n\/\/\/ let p: *mut int = ptr::null_mut();\n\/\/\/ assert!(p.is_null());\n\/\/\/ ```\n#[inline]\n#[unstable = \"may need a different name after pending changes to pointer types\"]\npub fn null_mut<T>() -> *mut T { 0 as *mut T }\n\n\/\/\/ Zeroes out `count * size_of::<T>` bytes of memory at `dst`\n#[inline]\n#[experimental = \"uncertain about naming and semantics\"]\n#[allow(experimental)]\npub unsafe fn zero_memory<T>(dst: *mut T, count: uint) {\n    set_memory(dst, 0, count);\n}\n\n\/\/\/ Swap the values at two mutable locations of the same type, without\n\/\/\/ deinitialising either.

A proper mutex implementation regardless of the \"flavor of task\" which is\n\/\/! acquiring the lock.\n\n\/\/ # Implementation of Rust mutexes\n\/\/\n\/\/ Most answers to the question of \"how do I use a mutex\" are \"use pthreads\",\n\/\/ but for Rust this isn't quite sufficient. Green threads cannot acquire an OS\n\/\/ mutex because they can context switch among many OS threads, leading to\n\/\/ deadlocks with other green threads.\n\/\/\n\/\/ Another problem for green threads grabbing an OS mutex is that POSIX dictates\n\/\/ that unlocking a mutex on a different thread from where it was locked is\n\/\/ undefined behavior. Remember that green threads can migrate among OS threads,\n\/\/ so this would mean that we would have to pin green threads to OS threads,\n\/\/ which is less than ideal.\n\/\/\n\/\/ ## Using deschedule\/reawaken\n\/\/\n\/\/ We already have primitives for descheduling\/reawakening tasks, so they're the\n\/\/ first obvious choice when implementing a mutex. The idea would be to have a\n\/\/ concurrent queue that everyone is pushed on to, and then the owner of the\n\/\/ mutex is the one popping from the queue.\n\/\/\n\/\/ Unfortunately, this is not very performant for native tasks. The suspected\n\/\/ reason for this is that each native thread is suspended on its own condition\n\/\/ variable, unique from all the other threads. In this situation, the kernel\n\/\/ has no idea what the scheduling semantics are of the user program, so all of\n\/\/ the threads are distributed among all cores on the system. This ends up\n\/\/ having very expensive wakeups of remote cores high up in the profile when\n\/\/ handing off the mutex among native tasks. On the other hand, when using an OS\n\/\/ mutex, the kernel knows that all native threads are contended on the same\n\/\/ mutex, so they're in theory all migrated to a single core (fast context\n\/\/ switching).\n\/\/\n\/\/ ## Mixing implementations\n\/\/\n\/\/ From that above information, we have two constraints. The first is that\n\/\/ green threads can't touch os mutexes, and the second is that native tasks\n\/\/ pretty much *must* touch an os mutex.\n\/\/\n\/\/ As a compromise, the queueing implementation is used for green threads and\n\/\/ the os mutex is used for native threads (why not have both?). This ends up\n\/\/ leading to fairly decent performance for both native threads and green\n\/\/ threads on various workloads (uncontended and contended).\n\/\/\n\/\/ The crux of this implementation is an atomic work which is CAS'd on many many\n\/\/ times in order to manage a few flags about who's blocking where and whether\n\/\/ it's locked or not.\n\nuse std::rt::local::Local;\nuse std::rt::task::{BlockedTask, Task};\nuse std::rt::thread::Thread;\nuse std::sync::atomics;\nuse std::unstable::mutex;\n\nuse q = sync::mpsc_intrusive;\n\npub static LOCKED: uint = 1 << 0;\npub static GREEN_BLOCKED: uint = 1 << 1;\npub static NATIVE_BLOCKED: uint = 1 << 2;\n\n\/\/\/ A mutual exclusion primitive useful for protecting shared data\n\/\/\/\n\/\/\/ This mutex is an implementation of a lock for all flavors of tasks which may\n\/\/\/ be grabbing. A common problem with green threads is that they cannot grab\n\/\/\/ locks (if they reschedule during the lock a contender could deadlock the\n\/\/\/ system), but this mutex does *not* suffer this problem.\n\/\/\/\n\/\/\/ This mutex will properly block tasks waiting for the lock to become\n\/\/\/ available. The mutex can also be statically initialized or created via a\n\/\/\/ `new` constructor.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ use extra::sync::mutex::Mutex;\n\/\/\/\n\/\/\/ let mut m = Mutex::new();\n\/\/\/ let guard = m.lock();\n\/\/\/ \/\/ do some work\n\/\/\/ drop(guard); \/\/ unlock the lock\n\/\/\/\n\/\/\/ {\n\/\/\/     let _g = m.lock();\n\/\/\/     \/\/ do some work in a scope\n\/\/\/ }\n\/\/\/\n\/\/\/ \/\/ now the mutex is unlocked\n\/\/\/ ```\npub struct Mutex {\n    priv lock: StaticMutex,\n}\n\n#[deriving(Eq)]\nenum Flavor {\n    Unlocked,\n    TryLockAcquisition,\n    GreenAcquisition,\n    NativeAcquisition,\n}\n\n\/\/\/ The static mutex type is provided to allow for static allocation of mutexes.\n\/\/\/\n\/\/\/ Note that this is a separate type because using a Mutex correctly means that\n\/\/\/ it needs to have a destructor run. In Rust, statics are not allowed to have\n\/\/\/ destructors. As a result, a `StaticMutex` has one extra method when compared\n\/\/\/ to a `Mutex`, a `destroy` method. This method is unsafe to call, and\n\/\/\/ documentation can be found directly on the method.\n\/\/\/\n\/\/\/ # Example\n\/\/\/\n\/\/\/ ```rust\n\/\/\/ use extra::sync::mutex::{StaticMutex, MUTEX_INIT};\n\/\/\/\n\/\/\/ static mut LOCK: StaticMutex = MUTEX_INIT;\n\/\/\/\n\/\/\/ unsafe {\n\/\/\/     let _g = LOCK.lock();\n\/\/\/     \/\/ do some productive work\n\/\/\/ }\n\/\/\/ \/\/ lock is unlocked here.\n\/\/\/ ```\npub struct StaticMutex {\n    \/\/\/ Current set of flags on this mutex\n    priv state: atomics::AtomicUint,\n    \/\/\/ Type of locking operation currently on this mutex\n    priv flavor: Flavor,\n    \/\/\/ uint-cast of the green thread waiting for this mutex\n    priv green_blocker: uint,\n    \/\/\/ uint-cast of the native thread waiting for this mutex\n    priv native_blocker: uint,\n    \/\/\/ an OS mutex used by native threads\n    priv lock: mutex::Mutex,\n\n    \/\/\/ A concurrent mpsc queue used by green threads, along with a count used\n    \/\/\/ to figure out when to dequeue and enqueue.\n    priv q: q::Queue<uint>,\n    priv green_cnt: atomics::AtomicUint,\n}\n\n\/\/\/ An RAII implementation of a \"scoped lock\" of a mutex.

They obey the same\nsemantics as C++0x. See the LLVM documentation on [[atomics]].\n\n[atomics]: http:\/\/llvm.org\/docs\/Atomics.html\n\nA quick refresher on memory ordering:\n\n* Acquire - a barrier for aquiring a lock. Subsequent reads and writes\n  take place after the barrier.\n* Release - a barrier for releasing a lock. Preceding reads and writes\n  take place before the barrier.\n* Sequentially consistent - sequentially consistent operations are\n  guaranteed to happen in order.

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value.

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested up into inputs and\n* outputs, and subdivides those into declared (input) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase.

\/\/\/ A mixer unit takes a number of input channels and mixes them to provide one or more output\n    \/\/\/ channels.\n    \/\/\/\n    \/\/\/ For example, the **StereoMixer** **SubType** in OS X

a specialised effect unit that distributes one or more channels in a\n    \/\/\/ single input to one or more channels in a single output.\n    \/\/\/\n    \/\/\/ Panner units must support a set of

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/!\n\/\/! The rust standard library is available to all rust crates by\n\/\/! default, just as if contained an `extern crate std` import at the\n\/\/! crate root. Therefore the standard library can be accessed in\n\/\/! `use` statements through the path `std`, as in `use std::thread`,\n\/\/! or in expressions through the absolute path `::std`, as in\n\/\/! `::std::thread::sleep_ms(100)`.\n\/\/!\n\/\/! Furthermore, the standard library defines [The Rust\n\/\/! Prelude](prelude\/index.html), a small collection of items, mostly\n\/\/! traits, that are imported into and available in every module.\n\/\/!\n\/\/! ## What is in the standard library\n\/\/!\n\/\/! The standard library is a set of minimal, battle-tested\n\/\/! core types and shared abstractions for the [broader Rust\n\/\/! ecosystem](https:\/\/crates.io) to build on.\n\/\/!\n\/\/! The [primitive types](#primitives), though not defined in the\n\/\/! standard library, are documented here, as are the predefined\n\/\/! [macros](#macros).\n\/\/!\n\/\/! ## Containers and collections\n\/\/!\n\/\/! The [`option`](option\/index.html) and\n\/\/! [`result`](result\/index.html) modules define optional and\n\/\/! error-handling types, `Option` and `Result`. The\n\/\/! [`iter`](iter\/index.html) module defines Rust's iterator trait,\n\/\/! [`Iterator`](iter\/trait.Iterator.html), which works with the `for`\n\/\/! loop to access collections.\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! Data may be shared by placing it in a reference-counted box or the\n\/\/! [`Rc`](rc\/index.html) type, and if further contained in a [`Cell`\n\/\/! or `RefCell`](cell\/index.html), may be mutated as well as shared.\n\/\/! Likewise, in a concurrent setting it is common to pair an\n\/\/! atomically-reference-counted box, [`Arc`](sync\/struct.Arc.html),\n\/\/! with a [`Mutex`](sync\/struct.Mutex.html) to get the same effect.\n\/\/!\n\/\/! The [`collections`](collections\/index.html) module defines maps,\n\/\/! sets, linked lists and other typical collection types, including\n\/\/! the common [`HashMap`](collections\/struct.HashMap.html).\n\/\/!\n\/\/! ## Platform abstractions and I\/O\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives.\n\/\/!\n\/\/! Common types of I\/O, including [files](fs\/struct.File.html),\n\/\/! [TCP](net\/struct.TcpStream.html),\n\/\/! [UDP](net\/struct.UdpSocket.html), are defined in the\n\/\/! [`io`](io\/index.html), [`fs`](fs\/index.html), and\n\/\/! [`net`](net\/index.html) modules.\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading\n\/\/! abstractions. [`sync`](sync\/index.html) contains further\n\/\/! primitive shared memory types, including\n\/\/! [`atomic`](sync\/atomic\/index.html) and\n\/\/! [`mpsc`](sync\/mpsc\/index.html), which contains the channel types\n\/\/! for message passing.\n\n\/\/ Do not remove on snapshot creation. Needed for bootstrap.

This error indicates that\nan integer literal given as a discriminant is not a member of the discriminant\ntype. For example:\n\n```\n#[repr(u8)]\nenum Thing {\n    A = 1024,\n    B = 5\n}\n```\n\nHere, 1024 lies outside the valid range for `u8`, so the discriminant for `A` is\ninvalid. You may want to change representation types to fix this, or else change\ninvalid discriminant values so that they fit within the existing type.\n\nNote also that without a representation manually defined, the compiler will\noptimize by using the smallest integer type possible.\n\"##,\n\nE0083: r##\"\nAt present, it's not possible to define a custom representation for an enum with\na single variant. As a workaround you can add a `Dummy` variant.\n\nSee: https:\/\/github.com\/rust-lang\/rust\/issues\/10292\n\"##,\n\nE0084: r##\"\nIt is impossible to define an integer type to be used to represent zero-variant\nenum values because there are no zero-variant enum values.

If you are trying to cast a numeric type\nto a bool, you can compare it with zero instead:\n\n```\nlet x = 5;\n\n\/\/ Ok\nlet x_is_nonzero = x != 0;\n\n\/\/ Not allowed, won't compile\nlet x_is_nonzero = x as bool;\n```\n\"##,\n\nE0081: r##\"\nEnum discriminants are used to differentiate enum variants stored in memory.\nThis error indicates that the same value was used for two or more variants,\nmaking them impossible to tell apart.\n\n```\n\/\/ Good.\nenum Enum {\n    P,\n    X = 3,\n    Y = 5\n}\n\n\/\/ Bad.\nenum Enum {\n    P = 3,\n    X = 3,\n    Y = 5\n}\n```\n\nNote that variants without a manually specified discriminant are numbered from\ntop to bottom starting from 0, so clashes can occur with seemingly unrelated\nvariants.\n\n```\nenum Bad {\n    X,\n    Y = 0\n}\n```\n\nHere `X` will have already been assigned the discriminant 0 by the time `Y` is\nencountered, so a conflict occurs.\n\"##,\n\nE0082: r##\"\nThe default type for enum discriminants is `isize`, but it can be adjusted by\nadding the `repr` attribute to the enum declaration. This error indicates that\nan integer literal given as a discriminant is not a member of the discriminant\ntype. For example:\n\n```\n#[repr(u8)]\nenum Thing {\n    A = 1024,\n    B = 5\n}\n```\n\nHere, 1024 lies outside the valid range for `u8`, so the discriminant for `A` is\ninvalid. You may want to change representation types to fix this, or else change\ninvalid discriminant values so that they fit within the existing type.\n\nNote also that without a representation manually defined, the compiler will\noptimize by using the smallest integer type possible.\n\"##,\n\nE0083: r##\"\nAt present, it's not possible to define a custom representation for an enum with\na single variant. As a workaround you can add a `Dummy` variant.\n\nSee: https:\/\/github.com\/rust-lang\/rust\/issues\/10292\n\"##,\n\nE0084: r##\"\nIt is impossible to define an integer type to be used to represent zero-variant\nenum values because there are no zero-variant enum values.

In order to have a nice smooth experience on Windows, the logic in this file\n\/\/! is here to find the MSVC linker and set it up in the default configuration\n\/\/! one would need to set up anyway.

{"text":"<commit_before>\/*!\n\nWithout bindless textures, using a texture in a shader requires binding the texture to a specific\nbind point before drawing. This not only slows down rendering, but may also prevent you from\ngrouping multiple draw calls into one because of the limitation to the number of available\ntexture units.\n\nInstead, bindless textures allow you to manually manipulate pointers to textures in video memory.\nYou can use thousands of textures if you want.\n\n# Initialization\n\nBefore using a bindless texture, you must turn it into a `ResidentTexture`. This is done by\ncalling `resident` on the texture you want.\n\nBindless textures are a very recent feature that is supported only by recent hardware and\ndrivers. `resident` will return an `Err` if this feature is not supported.\n\n```no_run\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\nlet texture = texture.resident().unwrap();\n```\n\nIn a real application, you will likely manage a `Vec<ResidentTexture>`.\n\n# Usage\n\nYou can then use a `TextureHandle` as if it was a pointer to a texture. A `TextureHandle` can be\nbuilt from a `&ResidentTexture` and can't outlive it.\n\n```ignore       \/\/ TODO: doctest ICEs on Rust 1.1 (but not on nightly, so this can be `no_run` eventually)\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n#[derive(Copy, Clone)]\nstruct UniformBuffer<'a> {\n    texture: glium::texture::TextureHandle<'a>,\n    some_value: f32,\n}\n\nimplement_uniform_block!(UniformBuffer<'a>, texture, some_value);\n\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::bindless::ResidentTexture = unsafe { std::mem::uninitialized() };\nlet uniform_buffer = glium::uniforms::UniformBuffer::new(&display, UniformBuffer {\n    texture: glium::texture::TextureHandle::new(&texture, &Default::default()),\n    some_value: 5.0,\n});\n# }\n```\n\nInside your shader, you can refer to the texture with a traditional `sampler*` variable.

This not only slows down rendering, but may also prevent you from\ngrouping multiple draw calls into one because of the limitation to the number of available\ntexture units.\n\nInstead, bindless textures allow you to manually manipulate pointers to textures in video memory.\nYou can use thousands of textures if you want.\n\n# Initialization\n\nBefore using a bindless texture, you must turn it into a `ResidentTexture`. This is done by\ncalling `resident` on the texture you want.\n\nBindless textures are a very recent feature that is supported only by recent hardware and\ndrivers. `resident` will return an `Err` if this feature is not supported.\n\n```no_run\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\nlet texture = texture.resident().unwrap();\n```\n\nIn a real application, you will likely manage a `Vec<ResidentTexture>`.\n\n# Usage\n\nYou can then use a `TextureHandle` as if it was a pointer to a texture. A `TextureHandle` can be\nbuilt from a `&ResidentTexture` and can't outlive it.\n\n```no_run\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n#[derive(Copy, Clone)]\nstruct UniformBuffer<'a> {\n    texture: glium::texture::TextureHandle<'a>,\n    some_value: f32,\n}\n\nimplement_uniform_block!(UniformBuffer<'a>, texture, some_value);\n\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::bindless::ResidentTexture = unsafe { std::mem::uninitialized() };\nlet uniform_buffer = glium::uniforms::UniformBuffer::new(&display, UniformBuffer {\n    texture: glium::texture::TextureHandle::new(&texture, &Default::default()),\n    some_value: 5.0,\n});\n# }\n```\n\nInside your shader, you can refer to the texture with a traditional `sampler*` variable. Glium\ncurrently doesn't check whether the type of your texture matches the expected type (but it may\ndo in the future).

This is the lowest level library through which allocation in Rust can be\n\/\/! performed.\n\/\/!\n\/\/! This library, like libcore, is not intended for general usage, but rather as\n\/\/! a building block of other libraries. The types and interfaces in this\n\/\/! library are reexported through the [standard library](..\/std\/index.html),\n\/\/! and should not be used through this library.\n\/\/!\n\/\/! Currently, there are four major definitions in this library.\n\/\/!\n\/\/! ## Boxed values\n\/\/!\n\/\/! The [`Box`](boxed\/index.html) type is a smart pointer type. There can\n\/\/! only be one owner of a `Box`, and the owner can decide to mutate the\n\/\/! contents, which live on the heap.\n\/\/!\n\/\/! This type can be sent among threads efficiently as the size of a `Box` value\n\/\/! is the same as that of a pointer. Tree-like data structures are often built\n\/\/! with boxes because each node often has only one owner, the parent.\n\/\/!\n\/\/! ## Reference counted pointers\n\/\/!\n\/\/! The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a thread. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](arc\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This types allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/! The [`heap`](heap\/index.html) module defines the low-level interface to the\n\/\/! default global allocator. It is not compatible with the libc allocator API.\n\n#![crate_name = \"alloc\"]\n#![crate_type = \"rlib\"]\n#![allow(unused_attributes)]\n#![unstable(feature = \"alloc\",\n            reason = \"this library is unlikely to be stabilized in its current \\\n                      form or name\",\n            issue = \"27783\")]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       issue_tracker_base_url = \"https:\/\/github.com\/rust-lang\/rust\/issues\/\",\n       test(no_crate_inject, attr(allow(unused_variables), deny(warnings))))]\n#![no_std]\n#![needs_allocator]\n#![deny(warnings)]\n\n#![feature(allocator)]\n#![feature(box_syntax)]\n#![feature(cfg_target_has_atomic)]\n#![feature(coerce_unsized)]\n#![feature(const_fn)]\n#![feature(core_intrinsics)]\n#![feature(custom_attribute)]\n#![feature(dropck_eyepatch)]\n#![cfg_attr(not(test), feature(exact_size_is_empty))]\n#![feature(fundamental)]\n#![feature(generic_param_attrs)]\n#![feature(lang_items)]\n#![feature(needs_allocator)]\n#![feature(optin_builtin_traits)]\n#![feature(placement_in_syntax)]\n#![feature(shared)]\n#![feature(staged_api)]\n#![feature(unboxed_closures)]\n#![feature(unique)]\n#![feature(unsize)]\n\n#![cfg_attr(not(test), feature(fused, fn_traits, placement_new_protocol))]\n#![cfg_attr(test, feature(test, box_heap))]\n\n\/\/ Allow testing this library\n\n#[cfg(test)]\n#[macro_use]\nextern crate std;\n\n\/\/ Module with internal macros used by other modules (needs to be included before other modules).\n#[macro_use]\nmod macros;\n\n\/\/ Heaps provided for low-level allocation strategies\n\npub mod heap;\n\n\/\/ Primitive types using the heaps above\n\n\/\/ Need to conditionally define the mod from `boxed.rs` to avoid\n\/\/ duplicating the lang-items when building in test cfg; but also need\n\/\/ to allow code to have `use boxed::HEAP;`\n\/\/ and `use boxed::Box;` declarations.\n#[cfg(not(test))]\npub mod boxed;\n#[cfg(test)]\nmod boxed {\n    pub use std::boxed::{Box, HEAP};\n}\n#[cfg(test)]\nmod boxed_test;\n#[cfg(target_has_atomic = \"ptr\")]\npub mod arc;\npub mod rc;\npub mod raw_vec;\npub mod oom;\n\npub use oom::oom;\n<commit_msg>Fix typo in liballoc\/lib.rs<commit_after>\/\/ Copyright 2014 The Rust Project Developers.

Similarly, the only way to create a true\n\/\/\/ trait object from a `TraitObject` value is with `transmute`.\n\/\/\/\n\/\/\/ [transmute]: ..\/intrinsics\/fn.transmute.html\n\/\/\/\n\/\/\/ Synthesizing a trait object with mismatched types—one where the\n\/\/\/ vtable does not correspond to the type of the value to which the\n\/\/\/ data pointer points—is highly likely to lead to undefined\n\/\/\/ behavior.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ #![feature(raw)]\n\/\/\/\n\/\/\/ use std::{mem, raw};\n\/\/\/\n\/\/\/ \/\/ an example trait\n\/\/\/ trait Foo {\n\/\/\/     fn bar(&self) -> i32;\n\/\/\/ }\n\/\/\/\n\/\/\/ impl Foo for i32 {\n\/\/\/     fn bar(&self) -> i32 {\n\/\/\/          *self + 1\n\/\/\/     }\n\/\/\/ }\n\/\/\/\n\/\/\/ let value: i32 = 123;\n\/\/\/\n\/\/\/ \/\/ let the compiler make a trait object\n\/\/\/ let object: &Foo = &value;\n\/\/\/\n\/\/\/ \/\/ look at the raw representation\n\/\/\/ let raw_object: raw::TraitObject = unsafe { mem::transmute(object) };\n\/\/\/\n\/\/\/ \/\/ the data pointer is the address of `value`\n\/\/\/ assert_eq!(raw_object.data as *const i32, &value as *const _);\n\/\/\/\n\/\/\/ let other_value: i32 = 456;\n\/\/\/\n\/\/\/ \/\/ construct a new object, pointing to a different `i32`, being\n\/\/\/ \/\/ careful to use the `i32` vtable from `object`\n\/\/\/ let synthesized: &Foo = unsafe {\n\/\/\/      mem::transmute(raw::TraitObject {\n\/\/\/          data: &other_value as *const _ as *mut (),\n\/\/\/          vtable: raw_object.vtable,\n\/\/\/      })\n\/\/\/ };\n\/\/\/\n\/\/\/ \/\/ it should work just as if we had constructed a trait object out of\n\/\/\/ \/\/ `other_value` directly\n\/\/\/ assert_eq!(synthesized.bar(), 457);\n\/\/\/ ```\n#[repr(C)]\n#[derive(Copy, Clone)]\n#[allow(missing_debug_implementations)]\npub struct TraitObject {\n    pub data: *mut (),\n    pub vtable: *mut (),\n}\n<|endoftext|>"}

But `Clone` works only for going from `&T`\n\/\/\/ to `T`. The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/\/ from any borrow of a given type.\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait ToOwned {\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    type Owned: Borrow<Self>;\n\n    \/\/\/ Creates owned data from borrowed data, usually by cloning.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ Basic usage:\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let s: &str = \"a\";\n    \/\/\/ let ss: String = s.to_owned();\n    \/\/\/\n    \/\/\/ let v: &[i32] = &[1, 2];\n    \/\/\/ let vv: Vec<i32> = v.to_owned();\n    \/\/\/ ```\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn to_owned(&self) -> Self::Owned;\n}\n\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\nimpl<T> ToOwned for T\n    where T: Clone\n{\n    type Owned = T;\n    fn to_owned(&self) -> T {\n        self.clone()\n    }\n}\n\n\/\/\/ A clone-on-write smart pointer.\n\/\/\/\n\/\/\/ The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/\/ can enclose and provide immutable access to borrowed data, and clone the\n\/\/\/ data lazily when mutation or ownership is required. The type is designed to\n\/\/\/ work with general borrowed data via the `Borrow` trait.\n\/\/\/\n\/\/\/ `Cow` implements `Deref`, which means that you can call\n\/\/\/ non-mutating methods directly on the data it encloses. If mutation\n\/\/\/ is desired, `to_mut` will obtain a mutable reference to an owned\n\/\/\/ value, cloning if necessary.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ use

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\/\/ Do not remove on snapshot creation.

Determining the type of each expression\n2. Resolving methods and traits\n3. Guaranteeing that most type rules are met (\"most?\", you say, \"why most?\"\n   Well, dear reader, read on)\n\nThe main entry point is `check_crate()`.  Type checking operates in\nseveral major phases:\n\n1. The collect phase first passes over all items and determines their\n   type, without examining their \"innards\".\n\n2. Variance inference then runs to compute the variance of each parameter\n\n3. Coherence checks for overlapping or orphaned impls\n\n4. Finally, the check phase then checks function bodies and so forth.\n   Within the check phase, we check each function body one at a time\n   (bodies of function expressions are checked as part of the\n   containing function).  Inference is used to supply types wherever\n   they are unknown. The actual checking of a function itself has\n   several phases (check, regionck, writeback), as discussed in the\n   documentation for the `check` module.\n\nThe type checker is defined into various submodules which are documented\nindependently:\n\n- astconv: converts the AST representation of types\n  into the `ty` representation\n\n- collect: computes the types of each top-level item and enters them into\n  the `cx.tcache` table for later use\n\n- coherence: enforces coherence rules, builds some tables\n\n- variance: variance inference\n\n- check: walks over function bodies and type checks them, inferring types for\n  local variables, type parameters, etc as necessary.\n\n- infer: finds the types to use for each type variable such that\n  all subtyping and assignment constraints are met.  In essence, the check\n  module specifies the constraints, and the infer module solves them.\n\n# Note\n\nThis API is completely unstable and subject to change.\n\n*\/\n\/\/ Do not remove on snapshot creation.

This sort of control flow is not always\n\/\/\/ anticipated, and has the possibility of causing subtle bugs through a\n\/\/\/ combination of two cricial components:\n\/\/\/\n\/\/\/ 1. A data structure is in a temporarily invalid state when the thread\n\/\/\/    panics.\n\/\/\/ 2. This broken invariant is then later observed.\n\/\/\/\n\/\/\/ Typically in Rust, it is difficult to perform step (2) because catching a\n\/\/\/ panic involves either spawning a thread (which in turns makes it difficult\n\/\/\/ to later witness broken invariants) or using the `recover` function in this\n\/\/\/ module. Additionally, even if an invariant is witnessed, it typically isn't a\n\/\/\/ problem in Rust because there's no uninitialized values (like in C or C++).\n\/\/\/\n\/\/\/ It is possible, however, for **logical** invariants to be broken in Rust,\n\/\/\/ which can end up causing behavioral bugs. Another key aspect of panic safety\n\/\/\/ in Rust is that, in the absence of `unsafe` code, a panic cannot lead to\n\/\/\/ memory unsafety.\n\/\/\/\n\/\/\/ That was a bit of a whirlwind tour of panic safety, but for more information\n\/\/\/ about panic safety and how it applies to Rust, see an [associated RFC][rfc].\n\/\/\/\n\/\/\/ [rfc]: https:\/\/github.com\/rust-lang\/rfcs\/blob\/master\/text\/1236-stabilize-catch-panic.md\n\/\/\/\n\/\/\/ ## What is `RecoverSafe`?\n\/\/\/\n\/\/\/ Now that we've got an idea of what panic safety is in Rust, it's also\n\/\/\/ important to understand what this trait represents. As mentioned above, one\n\/\/\/ way to witness broken invariants is through the `recover` function in this\n\/\/\/ module as it allows catching a panic and then re-using the environment of\n\/\/\/ the closure.\n\/\/\/\n\/\/\/ Simply put, a type `T` implements `RecoverSafe` if it cannot easily allow\n\/\/\/ witnessing a broken invariant through the use of `recover` (catching a\n\/\/\/ panic). This trait is a marker trait, so it is automatically implemented for\n\/\/\/ many types, and it is also structurally composed (e.g. a struct is recover\n\/\/\/ safe if all of its components are recover safe).\n\/\/\/\n\/\/\/ Note, however, that this is not an unsafe trait, so there is not a succinct\n\/\/\/ contract that this trait is providing. Instead it is intended as more of a\n\/\/\/ \"speed bump\" to alert users of `recover` that broken invariants may be\n\/\/\/ witnessed and may need to be accounted for.\n\/\/\/\n\/\/\/ ## Who implements `RecoverSafe`?\n\/\/\/\n\/\/\/ Types such as `&mut T` and `&RefCell<T>` are examples which are **not**\n\/\/\/ recover safe. The general idea is that any mutable state which can be shared\n\/\/\/ across `recover` is not recover safe by default. This is because it is very\n\/\/\/ easy to witness a broken invariant outside of `recover` as the data is\n\/\/\/ simply accesed as usual.\n\/\/\/\n\/\/\/ Types like `&Mutex<T>`, however, are recover safe because they implement\n\/\/\/ poisoning by default. They still allow witnessing a broken invariant, but\n\/\/\/ they already provide their own \"speed bumps\" to do so.\n\/\/\/\n\/\/\/ ## When should `RecoverSafe` be used?\n\/\/\/\n\/\/\/ Is not intended that most types or functions need to worry about this trait.\n\/\/\/ It is only used as a bound on the `recover` function and as mentioned above,\n\/\/\/ the lack of `unsafe` means it is mostly an advisory. The `AssertRecoverSafe`\n\/\/\/ wrapper struct in this module can be used to force this trait to be\n\/\/\/ implemented for any closed over variables passed to the `recover` function\n\/\/\/ (more on this below).\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} may not be safely transferred \\\n                            across a recover boundary\"]\npub trait RecoverSafe {}\n\n\/\/\/ A marker trait representing types where a shared reference is considered\n\/\/\/ recover safe.\n\/\/\/\n\/\/\/ This trait is namely not implemented by `UnsafeCell`, the root of all\n\/\/\/ interior mutability.\n\/\/\/\n\/\/\/ This is a \"helper marker trait\" used to provide impl blocks for the\n\/\/\/ `RecoverSafe` trait, for more information see that documentation.\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} contains interior mutability \\\n                            and a reference may not be safely transferrable \\\n                            across a recover boundary\"]\npub trait RefRecoverSafe {}\n\n\/\/\/ A simple wrapper around a type to assert that it is panic safe.\n\/\/\/\n\/\/\/ When using `recover` it may be the case that some of the closed over\n\/\/\/ variables are not panic safe. For example if `&mut T` is captured the\n\/\/\/ compiler will generate a warning indicating that it is not panic safe. It\n\/\/\/ may not be the case, however, that this is actually a problem due to the\n\/\/\/ specific usage of `recover` if panic safety is specifically taken into\n\/\/\/ account. This wrapper struct is useful for a quick and lightweight\n\/\/\/ annotation that a variable is indeed panic safe.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ #![feature(recover, std_panic)]\n\/\/\/\n\/\/\/ use std::panic::{self, AssertRecoverSafe};\n\/\/\/\n\/\/\/ let mut variable = 4;\n\/\/\/\n\/\/\/ \/\/ This code will not compile becuause the closure captures `&mut variable`\n\/\/\/ \/\/ which is not considered panic safe by default.\n\/\/\/\n\/\/\/ \/\/ panic::recover(|| {\n\/\/\/ \/\/     variable += 3;\n\/\/\/ \/\/ });\n\/\/\/\n\/\/\/ \/\/ This, however, will compile due to the `AssertRecoverSafe` wrapper\n\/\/\/ let result = {\n\/\/\/     let mut wrapper = AssertRecoverSafe::new(&mut variable);\n\/\/\/     panic::recover(move || {\n\/\/\/         **wrapper += 3;\n\/\/\/     })\n\/\/\/ };\n\/\/\/ \/\/ ...\n\/\/\/ ```\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\npub struct AssertRecoverSafe<T>(T);\n\n\/\/ Implementations of the `RecoverSafe` trait:\n\/\/\n\/\/ * By default everything is recover safe\n\/\/ * pointers T contains mutability of some form are not recover safe\n\/\/ * Unique, an owning pointer, lifts an implementation\n\/\/ * Types like Mutex\/RwLock which are explicilty poisoned are recover safe\n\/\/ * Our custom AssertRecoverSafe wrapper is indeed recover safe\nimpl RecoverSafe for .. {}\nimpl<'a, T: ?Sized> !RecoverSafe for &'a mut T {}\nimpl<'a, T: RefRecoverSafe + ?Sized> RecoverSafe for &'a T {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for *const T {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for *mut T {}\nimpl<T: RecoverSafe> RecoverSafe for Unique<T> {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Shared<T> {}\nimpl<T: ?Sized> RecoverSafe for Mutex<T> {}\nimpl<T: ?Sized> RecoverSafe for RwLock<T> {}\nimpl<T> RecoverSafe for AssertRecoverSafe<T> {}\n\n\/\/ not covered via the Shared impl above b\/c the inner contents use\n\/\/ Cell\/AtomicUsize, but the usage here is recover safe so we can lift the\n\/\/ impl up one level to Arc\/Rc itself\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Rc<T> {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Arc<T> {}\n\n\/\/ Pretty simple implementations for the `RefRecoverSafe` marker trait,\n\/\/ basically just saying that this is a marker trait and `UnsafeCell` is the\n\/\/ only thing which doesn't implement it (which then transitively applies to\n\/\/ everything else).\nimpl RefRecoverSafe for .. {}\nimpl<T: ?Sized> !RefRecoverSafe for UnsafeCell<T> {}\nimpl<T> RefRecoverSafe for AssertRecoverSafe<T> {}\n\nimpl<T> AssertRecoverSafe<T> {\n    \/\/\/ Creates a new `AssertRecoverSafe` wrapper around the provided type.\n    #[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n    pub fn new(t: T) -> AssertRecoverSafe<T> {\n        AssertRecoverSafe(t)\n    }\n}\n\nimpl<T> Deref for AssertRecoverSafe<T> {\n    type Target = T;\n\n    fn deref(&self) -> &T {\n        &self.0\n    }\n}\n\nimpl<T> DerefMut for AssertRecoverSafe<T> {\n    fn deref_mut(&mut self) -> &mut T {\n        &mut self.0\n    }\n}\n\n\/\/\/ Invokes a closure, capturing the cause of panic if one occurs.\n\/\/\/\n\/\/\/ This function will return `Ok` with the closure's result if the closure\n\/\/\/ does not panic, and will return `Err(cause)` if the closure panics.

Another key aspect of panic safety\n\/\/\/ in Rust is that, in the absence of `unsafe` code, a panic cannot lead to\n\/\/\/ memory unsafety.\n\/\/\/\n\/\/\/ That was a bit of a whirlwind tour of panic safety, but for more information\n\/\/\/ about panic safety and how it applies to Rust, see an [associated RFC][rfc].\n\/\/\/\n\/\/\/ [rfc]: https:\/\/github.com\/rust-lang\/rfcs\/blob\/master\/text\/1236-stabilize-catch-panic.md\n\/\/\/\n\/\/\/ ## What is `RecoverSafe`?\n\/\/\/\n\/\/\/ Now that we've got an idea of what panic safety is in Rust, it's also\n\/\/\/ important to understand what this trait represents. As mentioned above, one\n\/\/\/ way to witness broken invariants is through the `recover` function in this\n\/\/\/ module as it allows catching a panic and then re-using the environment of\n\/\/\/ the closure.\n\/\/\/\n\/\/\/ Simply put, a type `T` implements `RecoverSafe` if it cannot easily allow\n\/\/\/ witnessing a broken invariant through the use of `recover` (catching a\n\/\/\/ panic). This trait is a marker trait, so it is automatically implemented for\n\/\/\/ many types, and it is also structurally composed (e.g. a struct is recover\n\/\/\/ safe if all of its components are recover safe).\n\/\/\/\n\/\/\/ Note, however, that this is not an unsafe trait, so there is not a succinct\n\/\/\/ contract that this trait is providing. Instead it is intended as more of a\n\/\/\/ \"speed bump\" to alert users of `recover` that broken invariants may be\n\/\/\/ witnessed and may need to be accounted for.\n\/\/\/\n\/\/\/ ## Who implements `RecoverSafe`?\n\/\/\/\n\/\/\/ Types such as `&mut T` and `&RefCell<T>` are examples which are **not**\n\/\/\/ recover safe. The general idea is that any mutable state which can be shared\n\/\/\/ across `recover` is not recover safe by default. This is because it is very\n\/\/\/ easy to witness a broken invariant outside of `recover` as the data is\n\/\/\/ simply accesed as usual.\n\/\/\/\n\/\/\/ Types like `&Mutex<T>`, however, are recover safe because they implement\n\/\/\/ poisoning by default. They still allow witnessing a broken invariant, but\n\/\/\/ they already provide their own \"speed bumps\" to do so.\n\/\/\/\n\/\/\/ ## When should `RecoverSafe` be used?\n\/\/\/\n\/\/\/ Is not intended that most types or functions need to worry about this trait.\n\/\/\/ It is only used as a bound on the `recover` function and as mentioned above,\n\/\/\/ the lack of `unsafe` means it is mostly an advisory. The `AssertRecoverSafe`\n\/\/\/ wrapper struct in this module can be used to force this trait to be\n\/\/\/ implemented for any closed over variables passed to the `recover` function\n\/\/\/ (more on this below).\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} may not be safely transferred \\\n                            across a recover boundary\"]\npub trait RecoverSafe {}\n\n\/\/\/ A marker trait representing types where a shared reference is considered\n\/\/\/ recover safe.\n\/\/\/\n\/\/\/ This trait is namely not implemented by `UnsafeCell`, the root of all\n\/\/\/ interior mutability.\n\/\/\/\n\/\/\/ This is a \"helper marker trait\" used to provide impl blocks for the\n\/\/\/ `RecoverSafe` trait, for more information see that documentation.\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n#[rustc_on_unimplemented = \"the type {Self} contains interior mutability \\\n                            and a reference may not be safely transferrable \\\n                            across a recover boundary\"]\npub trait RefRecoverSafe {}\n\n\/\/\/ A simple wrapper around a type to assert that it is panic safe.\n\/\/\/\n\/\/\/ When using `recover` it may be the case that some of the closed over\n\/\/\/ variables are not panic safe. For example if `&mut T` is captured the\n\/\/\/ compiler will generate a warning indicating that it is not panic safe. It\n\/\/\/ may not be the case, however, that this is actually a problem due to the\n\/\/\/ specific usage of `recover` if panic safety is specifically taken into\n\/\/\/ account. This wrapper struct is useful for a quick and lightweight\n\/\/\/ annotation that a variable is indeed panic safe.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ #![feature(recover, std_panic)]\n\/\/\/\n\/\/\/ use std::panic::{self, AssertRecoverSafe};\n\/\/\/\n\/\/\/ let mut variable = 4;\n\/\/\/\n\/\/\/ \/\/ This code will not compile because the closure captures `&mut variable`\n\/\/\/ \/\/ which is not considered panic safe by default.\n\/\/\/\n\/\/\/ \/\/ panic::recover(|| {\n\/\/\/ \/\/     variable += 3;\n\/\/\/ \/\/ });\n\/\/\/\n\/\/\/ \/\/ This, however, will compile due to the `AssertRecoverSafe` wrapper\n\/\/\/ let result = {\n\/\/\/     let mut wrapper = AssertRecoverSafe::new(&mut variable);\n\/\/\/     panic::recover(move || {\n\/\/\/         **wrapper += 3;\n\/\/\/     })\n\/\/\/ };\n\/\/\/ \/\/ ...\n\/\/\/ ```\n#[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\npub struct AssertRecoverSafe<T>(T);\n\n\/\/ Implementations of the `RecoverSafe` trait:\n\/\/\n\/\/ * By default everything is recover safe\n\/\/ * pointers T contains mutability of some form are not recover safe\n\/\/ * Unique, an owning pointer, lifts an implementation\n\/\/ * Types like Mutex\/RwLock which are explicilty poisoned are recover safe\n\/\/ * Our custom AssertRecoverSafe wrapper is indeed recover safe\nimpl RecoverSafe for .. {}\nimpl<'a, T: ?Sized> !RecoverSafe for &'a mut T {}\nimpl<'a, T: RefRecoverSafe + ?Sized> RecoverSafe for &'a T {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for *const T {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for *mut T {}\nimpl<T: RecoverSafe> RecoverSafe for Unique<T> {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Shared<T> {}\nimpl<T: ?Sized> RecoverSafe for Mutex<T> {}\nimpl<T: ?Sized> RecoverSafe for RwLock<T> {}\nimpl<T> RecoverSafe for AssertRecoverSafe<T> {}\n\n\/\/ not covered via the Shared impl above b\/c the inner contents use\n\/\/ Cell\/AtomicUsize, but the usage here is recover safe so we can lift the\n\/\/ impl up one level to Arc\/Rc itself\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Rc<T> {}\nimpl<T: RefRecoverSafe + ?Sized> RecoverSafe for Arc<T> {}\n\n\/\/ Pretty simple implementations for the `RefRecoverSafe` marker trait,\n\/\/ basically just saying that this is a marker trait and `UnsafeCell` is the\n\/\/ only thing which doesn't implement it (which then transitively applies to\n\/\/ everything else).\nimpl RefRecoverSafe for .. {}\nimpl<T: ?Sized> !RefRecoverSafe for UnsafeCell<T> {}\nimpl<T> RefRecoverSafe for AssertRecoverSafe<T> {}\n\nimpl<T> AssertRecoverSafe<T> {\n    \/\/\/ Creates a new `AssertRecoverSafe` wrapper around the provided type.\n    #[unstable(feature = \"recover\", reason = \"awaiting feedback\", issue = \"27719\")]\n    pub fn new(t: T) -> AssertRecoverSafe<T> {\n        AssertRecoverSafe(t)\n    }\n}\n\nimpl<T> Deref for AssertRecoverSafe<T> {\n    type Target = T;\n\n    fn deref(&self) -> &T {\n        &self.0\n    }\n}\n\nimpl<T> DerefMut for AssertRecoverSafe<T> {\n    fn deref_mut(&mut self) -> &mut T {\n        &mut self.0\n    }\n}\n\n\/\/\/ Invokes a closure, capturing the cause of panic if one occurs.\n\/\/\/\n\/\/\/ This function will return `Ok` with the closure's result if the closure\n\/\/\/ does not panic, and will return `Err(cause)` if the closure panics.

{"text":"<commit_before>\/\/! Crate `ruma_api` contains core types used to define the requests and responses for each endpoint\n\/\/! in the various [Matrix](https:\/\/matrix.org) API specifications.\n\/\/! These types can be shared by client and server code for all Matrix APIs.\n\/\/!\n\/\/! When implementing a new Matrix API, each endpoint has a request type which implements\n\/\/! `Endpoint`, and a response type connected via an associated type.\n\/\/!\n\/\/! An implementation of `Endpoint` contains all the information about the HTTP method, the path and\n\/\/! input parameters for requests, and the structure of a successful response.\n\/\/! Such types can then be used by client code to make requests, and by server code to fulfill\n\/\/! those requests.\n\n#![warn(rust_2018_idioms)]\n#![deny(missing_copy_implementations, missing_debug_implementations, missing_docs)]\n\nuse std::convert::{TryFrom, TryInto};\n\nuse http::Method;\n\n\/\/\/ Generates a `ruma_api::Endpoint` from a concise definition.\n\/\/\/\n\/\/\/ The macro expects the following structure as input:\n\/\/\/\n\/\/\/ ```text\n\/\/\/ ruma_api! {\n\/\/\/     metadata {\n\/\/\/         description: &'static str,\n\/\/\/         method: http::Method,\n\/\/\/         name: &'static str,\n\/\/\/         path: &'static str,\n\/\/\/         rate_limited: bool,\n\/\/\/         requires_authentication: bool,\n\/\/\/     }\n\/\/\/\n\/\/\/     request {\n\/\/\/         \/\/ Struct fields for each piece of data required\n\/\/\/         \/\/ to make a request to this API endpoint.\n\/\/\/     }\n\/\/\/\n\/\/\/     response {\n\/\/\/         \/\/ Struct fields for each piece of data expected\n\/\/\/         \/\/ in the response from this API endpoint.\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ This will generate a `ruma_api::Metadata` value to be used for the `ruma_api::Endpoint`'s\n\/\/\/ associated constant, single `Request` and `Response` structs, and the necessary trait\n\/\/\/ implementations to convert the request into a `http::Request` and to create a response from a\n\/\/\/ `http::Response` and vice versa.\n\/\/\/\n\/\/\/ The details of each of the three sections of the macros are documented below.\n\/\/\/\n\/\/\/ ## Metadata\n\/\/\/\n\/\/\/ *   `description`: A short description of what the endpoint does.\n\/\/\/ *   `method`: The HTTP method used for requests to the endpoint.\n\/\/\/     It's not necessary to import `http::Method`'s associated constants. Just write\n\/\/\/     the value as if it was imported, e.g. `GET`.\n\/\/\/ *   `name`: A unique name for the endpoint.\n\/\/\/     Generally this will be the same as the containing module.\n\/\/\/ *   `path`: The path component of the URL for the endpoint, e.g. \"\/foo\/bar\".\n\/\/\/     Components of the path that are parameterized can indicate a varible by using a Rust\n\/\/\/     identifier prefixed with a colon, e.g. `\/foo\/:some_parameter`.\n\/\/\/     A corresponding query string parameter will be expected in the request struct (see below\n\/\/\/     for details).\n\/\/\/ *   `rate_limited`: Whether or not the endpoint enforces rate limiting on requests.\n\/\/\/ *   `requires_authentication`: Whether or not the endpoint requires a valid access token.\n\/\/\/\n\/\/\/ ## Request\n\/\/\/\n\/\/\/ The request block contains normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There are also a few special attributes available to control how the struct is converted into a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = HEADER_NAME)]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the request.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/ *   `#[ruma_api(path)]`: Fields with this attribute will be inserted into the matching path\n\/\/\/     component of the request URL.\n\/\/\/ *   `#[ruma_api(query)]`: Fields with this attribute will be inserting into the URL's query\n\/\/\/     string.\n\/\/\/ *   `#[ruma_api(query_map)]`: Instead of individual query fields, one query_map field, of any\n\/\/\/     type that implements `IntoIterator<Item = (String, String)>` (e.g.\n\/\/\/     `HashMap<String, String>`, can be used for cases where an endpoint supports arbitrary query\n\/\/\/     parameters.\n\/\/\/\n\/\/\/ Any field that does not include one of these attributes will be part of the request's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Response\n\/\/\/\n\/\/\/ Like the request block, the response block consists of normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There is also a special attribute available to control how the struct is created from a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = HEADER_NAME)]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the response.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/\n\/\/\/ Any field that does not include the above attribute will be expected in the response's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Newtype bodies\n\/\/\/\n\/\/\/ Both the request and response block also support \"newtype bodies\" by using the\n\/\/\/ `#[ruma_api(body)]` attribute on a field. If present on a field, the entire request or response\n\/\/\/ body will be treated as the value of the field. This allows you to treat the entire request or\n\/\/\/ response body as a specific type, rather than a JSON object with named fields. Only one field in\n\/\/\/ each struct can be marked with this attribute. It is an error to have a newtype body field and\n\/\/\/ normal body fields within the same struct.\n\/\/\/\n\/\/\/ There is another kind of newtype body that is enabled with `#[ruma_api(raw_body)]`. It is used\n\/\/\/ for endpoints in which the request or response body can be arbitrary bytes instead of a JSON\n\/\/\/ objects.

Crate `ruma_api` contains core types used to define the requests and responses for each endpoint\n\/\/! in the various [Matrix](https:\/\/matrix.org) API specifications.\n\/\/! These types can be shared by client and server code for all Matrix APIs.\n\/\/!\n\/\/! When implementing a new Matrix API, each endpoint has a request type which implements\n\/\/! `Endpoint`, and a response type connected via an associated type.\n\/\/!\n\/\/! An implementation of `Endpoint` contains all the information about the HTTP method, the path and\n\/\/! input parameters for requests, and the structure of a successful response.\n\/\/! Such types can then be used by client code to make requests, and by server code to fulfill\n\/\/! those requests.\n\n#![warn(rust_2018_idioms)]\n#![deny(missing_copy_implementations, missing_debug_implementations, missing_docs)]\n\nuse std::convert::{TryFrom, TryInto};\n\nuse http::Method;\n\n\/\/\/ Generates a `ruma_api::Endpoint` from a concise definition.\n\/\/\/\n\/\/\/ The macro expects the following structure as input:\n\/\/\/\n\/\/\/ ```text\n\/\/\/ ruma_api! {\n\/\/\/     metadata {\n\/\/\/         description: &'static str,\n\/\/\/         method: http::Method,\n\/\/\/         name: &'static str,\n\/\/\/         path: &'static str,\n\/\/\/         rate_limited: bool,\n\/\/\/         requires_authentication: bool,\n\/\/\/     }\n\/\/\/\n\/\/\/     request {\n\/\/\/         \/\/ Struct fields for each piece of data required\n\/\/\/         \/\/ to make a request to this API endpoint.\n\/\/\/     }\n\/\/\/\n\/\/\/     response {\n\/\/\/         \/\/ Struct fields for each piece of data expected\n\/\/\/         \/\/ in the response from this API endpoint.\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ This will generate a `ruma_api::Metadata` value to be used for the `ruma_api::Endpoint`'s\n\/\/\/ associated constant, single `Request` and `Response` structs, and the necessary trait\n\/\/\/ implementations to convert the request into a `http::Request` and to create a response from a\n\/\/\/ `http::Response` and vice versa.\n\/\/\/\n\/\/\/ The details of each of the three sections of the macros are documented below.\n\/\/\/\n\/\/\/ ## Metadata\n\/\/\/\n\/\/\/ *   `description`: A short description of what the endpoint does.\n\/\/\/ *   `method`: The HTTP method used for requests to the endpoint.\n\/\/\/     It's not necessary to import `http::Method`'s associated constants. Just write\n\/\/\/     the value as if it was imported, e.g. `GET`.\n\/\/\/ *   `name`: A unique name for the endpoint.\n\/\/\/     Generally this will be the same as the containing module.\n\/\/\/ *   `path`: The path component of the URL for the endpoint, e.g. \"\/foo\/bar\".\n\/\/\/     Components of the path that are parameterized can indicate a varible by using a Rust\n\/\/\/     identifier prefixed with a colon, e.g. `\/foo\/:some_parameter`.\n\/\/\/     A corresponding query string parameter will be expected in the request struct (see below\n\/\/\/     for details).\n\/\/\/ *   `rate_limited`: Whether or not the endpoint enforces rate limiting on requests.\n\/\/\/ *   `requires_authentication`: Whether or not the endpoint requires a valid access token.\n\/\/\/\n\/\/\/ ## Request\n\/\/\/\n\/\/\/ The request block contains normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There are also a few special attributes available to control how the struct is converted into a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = HEADER_NAME)]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the request.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/ *   `#[ruma_api(path)]`: Fields with this attribute will be inserted into the matching path\n\/\/\/     component of the request URL.\n\/\/\/ *   `#[ruma_api(query)]`: Fields with this attribute will be inserting into the URL's query\n\/\/\/     string.\n\/\/\/ *   `#[ruma_api(query_map)]`: Instead of individual query fields, one query_map field, of any\n\/\/\/     type that implements `IntoIterator<Item = (String, String)>` (e.g.\n\/\/\/     `HashMap<String, String>`, can be used for cases where an endpoint supports arbitrary query\n\/\/\/     parameters.\n\/\/\/\n\/\/\/ Any field that does not include one of these attributes will be part of the request's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Response\n\/\/\/\n\/\/\/ Like the request block, the response block consists of normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There is also a special attribute available to control how the struct is created from a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = HEADER_NAME)]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the response.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/\n\/\/\/ Any field that does not include the above attribute will be expected in the response's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Newtype bodies\n\/\/\/\n\/\/\/ Both the request and response block also support \"newtype bodies\" by using the\n\/\/\/ `#[ruma_api(body)]` attribute on a field. If present on a field, the entire request or response\n\/\/\/ body will be treated as the value of the field. This allows you to treat the entire request or\n\/\/\/ response body as a specific type, rather than a JSON object with named fields. Only one field in\n\/\/\/ each struct can be marked with this attribute. It is an error to have a newtype body field and\n\/\/\/ normal body fields within the same struct.\n\/\/\/\n\/\/\/ There is another kind of newtype body that is enabled with `#[ruma_api(raw_body)]`. It is used\n\/\/\/ for endpoints in which the request or response body can be arbitrary bytes instead of a JSON\n\/\/\/ objects. A field with `#[ruma_api(raw_body)]` needs to have the type `Vec<u8>`.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```\n\/\/\/ pub mod some_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: POST,\n\/\/\/             name: \"some_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/endpoint\/:baz\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             pub foo: String,\n\/\/\/\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             #[ruma_api(query)]\n\/\/\/             pub bar: String,\n\/\/\/\n\/\/\/             #[ruma_api(path)]\n\/\/\/             pub baz: String,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             pub value: String,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/\n\/\/\/ pub mod newtype_body_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/     use serde::{Deserialize, Serialize};\n\/\/\/\n\/\/\/     #[derive(Clone, Debug, Deserialize, Serialize)]\n\/\/\/     pub struct MyCustomType {\n\/\/\/         pub foo: String,\n\/\/\/     }\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: PUT,\n\/\/\/             name: \"newtype_body_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/newtype\/body\/endpoint\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             #[ruma_api(raw_body)]\n\/\/\/             pub file: Vec<u8>,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(body)]\n\/\/\/             pub my_custom_type: MyCustomType,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n\/\/\/\n\/\/\/ ## Fallible deserialization\n\/\/\/\n\/\/\/ All request and response types also derive [`Outgoing`][Outgoing].

{"text":"<commit_before><commit_msg>Add a benchmark computing a Fibonacci number recursively<commit_after>\/\/! Benchmark Fibonacci numbers, F(n) = F(n-1) + F(n-2)\n\/\/!\n\/\/! Recursion is a horrible way to compute this -- roughly O(2ⁿ).\n\/\/! \n\/\/! It's potentially interesting for rayon::join, because the splits are\n\/\/! unequal.  F(n-1) has roughly twice as much work to do as F(n-2).  The\n\/\/! imbalance might make it more likely to leave idle threads ready to steal\n\/\/! jobs.  We can also see if there's any effect to having the larger job first\n\/\/! or second.\n\/\/!\n\/\/! We're doing very little real work in each job, so the rayon overhead is\n\/\/! going to dominate.  The serial recursive version will likely be faster,\n\/\/! unless you have a whole lot of CPUs.  The iterative version reveals the\n\/\/! joke.\n\n#![feature(test)]\n\nextern crate rayon;\nextern crate test;\n\nconst N: u32 = 32;\nconst FN: u32 = 2178309;\n\n\n#[bench]\n\/\/\/ Compute the Fibonacci number recursively, without any parallelism.\nfn fibonacci_recursive(b: &mut test::Bencher) {\n\n    fn fib(n: u32) -> u32 {\n        if n < 2 { return n; }\n\n        fib(n - 1) + fib(n - 2)\n    }\n\n    b.iter(|| assert_eq!(fib(test::black_box(N)), FN));\n}\n\n\n#[bench]\n\/\/\/ Compute the Fibonacci number recursively, using rayon::join.\n\/\/\/ The larger branch F(N-1) is computed first.\nfn fibonacci_join_1_2(b: &mut test::Bencher) {\n    rayon::initialize();\n\n    fn fib(n: u32) -> u32 {\n        if n < 2 { return n; }\n\n        let (a, b) = rayon::join(\n            || fib(n - 1),\n            || fib(n - 2));\n        a + b\n    }\n\n    b.iter(|| assert_eq!(fib(test::black_box(N)), FN));\n}\n\n\n#[bench]\n\/\/\/ Compute the Fibonacci number recursively, using rayon::join.\n\/\/\/ The smaller branch F(N-2) is computed first.\nfn fibonacci_join_2_1(b: &mut test::Bencher) {\n    rayon::initialize();\n\n    fn fib(n: u32) -> u32 {\n        if n < 2 { return n; }\n\n        let (a, b) = rayon::join(\n            || fib(n - 2),\n            || fib(n - 1));\n        a + b\n    }\n\n    b.iter(|| assert_eq!(fib(test::black_box(N)), FN));\n}\n\n\n#[bench]\n\/\/\/ Compute the Fibonacci number iteratively, just to show how silly the others\n\/\/\/ are.

trait by using the Request type as Self<commit_after>\/\/! Crate ruma_api contains core types used to define the requests and responses for each endpoint\n\/\/! in the various [Matrix](https:\/\/matrix.org) API specifications.\n\/\/! These types can be shared by client and server code for all Matrix APIs.\n\/\/!\n\/\/! When implementing a new Matrix API, each endpoint has a type that implements `Endpoint`, plus\n\/\/! the necessary associated types.\n\/\/! An implementation of `Endpoint` contains all the information about the HTTP method, the path and\n\/\/! input parameters for requests, and the structure of a successful response.\n\/\/! Such types can then be used by client code to make requests, and by server code to fulfill\n\/\/! those requests.\n\n#![deny(\n    missing_copy_implementations,\n    missing_debug_implementations,\n

The traits in this module provide a general way to talk about conversions\n\/\/! from one type to another. They follow the standard Rust conventions of\n\/\/! `as`\/`into`\/`from`.\n\/\/!\n\/\/! Like many traits, these are often used as bounds for generic functions, to\n\/\/! support arguments of multiple types.\n\/\/!\n\/\/! - Impl the `As*` traits for reference-to-reference conversions\n\/\/! - Impl the `Into` trait when you want to consume the value in the conversion\n\/\/! - The `From` trait is the most flexible, usefull for values _and_ references conversions\n\/\/!\n\/\/! As a library writer, you should prefer implementing `From<T>` rather than\n\/\/! `Into<U>`, as `From` provides greater flexibility and offer the equivalent `Into`\n\/\/! implementation for free, thanks to a blanket implementation in the standard library.\n\/\/!\n\/\/! **Note: these traits must not fail**. If the conversion can fail, you must use a dedicated\n\/\/! method which return an `Option<T>` or a `Result<T, E>`.\n\/\/!\n\/\/! # Generic impl\n\/\/!\n\/\/! - `AsRef` and `AsMut` auto-dereference if the inner type is a reference\n\/\/! - `From<U> for T` implies `Into<T> for U`\n\/\/! - `From` and `Into` are reflexive, which means that all types can `into()`\n\/\/!   themselves and `from()` themselves\n\/\/!\n\/\/!

Though due to the complex\n\/\/! inter-dependencies within `std` that will be a challenging goal to\n\/\/! achieve.\n\n#![allow(missing_debug_implementations)]\n\ncfg_if! {\n    if #[cfg(unix)] {\n        mod unix;\n        pub use self::unix::*;\n    } else if #[cfg(windows)] {\n        mod windows;\n        pub use self::windows::*;\n    } else if #[cfg(target_os = \"cloudabi\")] {\n        mod cloudabi;\n        pub use self::cloudabi::*;\n    } else if #[cfg(target_os = \"redox\")] {\n        mod redox;\n        pub use self::redox::*;\n    } else if #[cfg(target_arch = \"wasm32\")] {\n        mod wasm;\n        pub use self::wasm::*;\n    } else {\n        compile_error!(\"libstd doesn't compile for this platform yet\");\n    }\n}\n\n\/\/ Import essential modules from both platforms when documenting.

Automatically handles\n\/\/\/ the padding necessary for buffer-to-texture and texture-to-buffer copies.\n\/\/\/\n\/\/\/ Note: as of `wgpu` 0.6, texture-to-buffer and buffer-to-texture copies require that image rows\n\/\/\/ are padded to a multiple `wgpu::COPY_BYTES_PER_ROW_ALIGNMENT` bytes.

This module provides a generic way to compute the hash of a value. The\n\/\/! simplest way to make a type hashable is to use `#[derive(Hash)]`:\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! ```rust\n\/\/! use std::hash::{Hash, SipHasher, Hasher};\n\/\/!\n\/\/! #[derive(Hash)]\n\/\/! struct Person {\n\/\/!     id: u32,\n\/\/!     name: String,\n\/\/!     phone: u64,\n\/\/! }\n\/\/!\n\/\/! let person1 = Person { id: 5, name: \"Janet\".to_string(), phone: 555_666_7777 };\n\/\/! let person2 = Person { id: 5, name: \"Bob\".to_string(), phone: 555_666_7777 };\n\/\/!\n\/\/! assert!(hash(&person1) != hash(&person2));\n\/\/!\n\/\/! fn hash<T: Hash>(t: &T) -> u64 {\n\/\/!     let mut s = SipHasher::new();\n\/\/!     t.hash(&mut s);\n\/\/!     s.finish()\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! If you need more control over how a value is hashed, you need to implement\n\/\/! the trait `Hash`:\n\/\/!\n\/\/! ```rust\n\/\/! use std::hash::{Hash, Hasher, SipHasher};\n\/\/!\n\/\/! struct Person {\n\/\/!

This module provides a generic way to compute the hash of a value. The\n\/\/! simplest way to make a type hashable is to use `#[derive(Hash)]`:\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! ```rust\n\/\/! use std::hash::{Hash, SipHasher, Hasher};\n\/\/!\n\/\/! #[derive(Hash)]\n\/\/! struct Person {\n\/\/!     id: u32,\n\/\/!     name: String,\n\/\/!     phone: u64,\n\/\/! }\n\/\/!\n\/\/! let person1 = Person { id: 5, name: \"Janet\".to_string(), phone: 555_666_7777 };\n\/\/! let person2 = Person { id: 5, name: \"Bob\".to_string(), phone: 555_666_7777 };\n\/\/!\n\/\/! assert!(hash(&person1) != hash(&person2));\n\/\/!\n\/\/! fn hash<T: Hash>(t: &T) -> u64 {\n\/\/!     let mut s = SipHasher::new();\n\/\/!     t.hash(&mut s);\n\/\/!     s.finish()\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! If you need more control over how a value is hashed, you need to implement\n\/\/! the trait `Hash`:\n\/\/!\n\/\/! ```rust\n\/\/! use std::hash::{Hash, Hasher, SipHasher};\n\/\/!\n\/\/! struct Person {\n\/\/!     id: u32,\n\/\/! # #[allow(dead_code)]\n\/\/!     name: String,\n\/\/!     phone: u64,\n\/\/! }\n\/\/!\n\/\/! impl Hash for Person {\n\/\/!     fn hash<H: Hasher>(&self, state: &mut H) {\n\/\/!         self.id.hash(state);\n\/\/!         self.phone.hash(state);\n\/\/!     }\n\/\/! }\n\/\/!\n\/\/! let person1 = Person { id: 5, name: \"Janet\".to_string(), phone: 555_666_7777 };\n\/\/! let person2 = Person { id: 5, name: \"Bob\".to_string(), phone: 555_666_7777 };\n\/\/!\n\/\/! assert_eq!(hash(&person1), hash(&person2));\n\/\/!\n\/\/! fn hash<T: Hash>(t: &T) -> u64 {\n\/\/!     let mut s = SipHasher::new();\n\/\/!     t.hash(&mut s);\n\/\/!     s.finish()\n\/\/! }\n\/\/! ```\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\nuse prelude::v1::*;\n\nuse fmt;\nuse marker;\nuse mem;\n\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub use self::sip::SipHasher;\n\nmod sip;\n\n\/\/\/ A hashable type.\n\/\/\/\n\/\/\/ The `H` type parameter is an abstract hash state that is used by the `Hash`\n\/\/\/ to compute the hash.\n\/\/\/\n\/\/\/ If you are also implementing `Eq`, there is an additional property that\n\/\/\/ is important:\n\/\/\/\n\/\/\/ ```text\n\/\/\/ k1 == k2 -> hash(k1) == hash(k2)\n\/\/\/ ```\n\/\/\/\n\/\/\/ In other words, if two keys are equal, their hashes should also be equal.\n\/\/\/ `HashMap` and `HashSet` both rely on this behavior.\n\/\/\/\n\/\/\/ ## Derivable\n\/\/\/\n\/\/\/ This trait can be used with `#[derive]` if all fields implement `Hash`.\n\/\/\/ When `derive`d, the resulting hash will be the combination of the values\n\/\/\/ from calling `.hash()` on each field.\n\/\/\/\n\/\/\/ ## How can I implement `Hash`?\n\/\/\/\n\/\/\/ If you need more control over how a value is hashed, you need to implement\n\/\/\/ the trait `Hash`:\n\/\/\/\n\/\/\/ ```\n\/\/\/ use std::hash::{Hash, Hasher};\n\/\/\/\n\/\/\/ struct Person {\n\/\/\/     id: u32,\n\/\/\/     name: String,\n\/\/\/     phone: u64,\n\/\/\/ }\n\/\/\/\n\/\/\/ impl Hash for Person {\n\/\/\/     fn hash<H: Hasher>(&self, state: &mut H) {\n\/\/\/         self.id.hash(state);\n\/\/\/         self.phone.hash(state);\n\/\/\/     }\n\/\/\/ }\n\/\/\/ ```\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait Hash {\n    \/\/\/ Feeds this value into the state given, updating the hasher as necessary.\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn hash<H: Hasher>(&self, state: &mut H);\n\n    \/\/\/ Feeds a slice of this type into the state provided.\n    #[stable(feature = \"hash_slice\", since = \"1.3.0\")]\n    fn hash_slice<H: Hasher>(data: &[Self], state: &mut H)\n        where Self: Sized\n    {\n        for piece in data {\n            piece.hash(state);\n        }\n    }\n}\n\n\/\/\/ A trait which represents the ability to hash an arbitrary stream of bytes.\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait Hasher {\n    \/\/\/ Completes a round of hashing, producing the output hash generated.\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn finish(&self) -> u64;\n\n    \/\/\/ Writes some data into this `Hasher`\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn write(&mut self, bytes: &[u8]);\n\n    \/\/\/ Write a single `u8` into this hasher\n    #[inline]\n    #[stable(feature = \"hasher_write\", since = \"1.3.0\")]\n    fn write_u8(&mut self, i: u8) {\n        self.write(&[i])\n    }\n    \/\/\/ Write a single `u16` into this hasher.\n    #[inline]\n    #[stable(feature = \"hasher_write\", since = \"1.3.0\")]\n    fn write_u16(&mut self, i: u16) {\n        self.write(&unsafe { mem::transmute::<_, [u8;

In Rust, some simple types are \"implicitly copyable\" and when you\n\/\/! assign them or pass them as arguments, the receiver will get a copy,\n\/\/! leaving the original value in place. These types do not require\n\/\/! allocation to copy and do not have finalizers (i.e. they do not\n\/\/! contain owned boxes or implement `Drop`), so the compiler considers\n\/\/! them cheap and safe to copy.

Basic usage example:\n\/\/!\n\/\/! ```\n\/\/! let s = String::new(); \/\/ String type implements Clone\n\/\/! let copy = s.clone(); \/\/ so we can clone it\n\/\/! ```\n\/\/!\n\/\/! To easily implement the Clone trait, you can also use\n\/\/! `#[derive(Clone)]`. Example:\n\/\/!\n\/\/! ```\n\/\/! #[derive(Clone)] \/\/ we add the Clone trait to Morpheus struct\n\/\/! struct Morpheus {\n\/\/!    blue_pill: f32,\n\/\/!    red_pill: i64,\n\/\/! }\n\/\/!\n\/\/! fn main() {\n\/\/!    let f = Morpheus { blue_pill: 0.0, red_pill: 0 };\n\/\/!    let copy = f.clone(); \/\/ and now we can clone it!\n\/\/! }\n\/\/! ```\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\nuse marker::Sized;\n\n\/\/\/ A common trait for cloning an object.\n\/\/\/\n\/\/\/ This trait can be used with `#[derive]`.\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait Clone : Sized {\n    \/\/\/ Returns a copy of the value.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let hello = \"Hello\"; \/\/ &str implements Clone\n    \/\/\/\n    \/\/\/ assert_eq!(\"Hello\", hello.clone());\n    \/\/\/ ```\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn clone(&self) -> Self;\n\n    \/\/\/ Performs copy-assignment from `source`.\n    \/\/\/\n    \/\/\/ `a.clone_from(&b)` is equivalent to `a = b.clone()` in functionality,\n    \/\/\/ but can be overridden to reuse the resources of `a` to avoid unnecessary\n    \/\/\/ allocations.\n    #[inline(always)]\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn clone_from(&mut self, source: &Self) {\n        *self = source.clone()\n    }\n}\n\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\nimpl<'a, T: ?Sized> Clone for &'a T {\n    \/\/\/ Returns a shallow copy of the reference.\n    #[inline]\n    fn clone(&self) -> &'a T { *self }\n}\n\nmacro_rules! clone_impl {\n    ($t:ty) => {\n        #[stable(feature = \"rust1\", since = \"1.0.0\")]\n        impl Clone for $t {\n            \/\/\/ Returns a deep copy of the value.\n            #[inline]\n            fn clone(&self) -> $t { *self }\n        }\n    }\n}\n\nclone_impl! { isize }\nclone_impl! { i8 }\nclone_impl! { i16 }\nclone_impl! { i32 }\nclone_impl! { i64 }\n\nclone_impl! { usize }\nclone_impl! { u8 }\nclone_impl! { u16 }\nclone_impl! { u32 }\nclone_impl! { u64 }\n\nclone_impl! { f32 }\nclone_impl! { f64 }\n\nclone_impl! { () }\nclone_impl! { bool }\nclone_impl! { char }\n<|endoftext|>"}

Arenas are a type of allocator that destroy the objects within, all at\n\/\/! once, once the arena itself is destroyed. They do not support deallocation\n\/\/! of individual objects while the arena itself is still alive. The benefit\n\/\/! of an arena is very fast allocation; just a pointer bump.\n\/\/!\n\/\/! This crate implements `TypedArena`, a simple arena that can only hold\n\/\/! objects of a single type.\n\n#![crate_name = \"arena\"]\n#![unstable(feature = \"rustc_private\", issue = \"27812\")]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       test(no_crate_inject, attr(deny(warnings))))]\n#![cfg_attr(not(stage0), deny(warnings))]\n\n#![feature(alloc)]\n#![feature(core_intrinsics)]\n#![feature(heap_api)]\n#![feature(heap_api)]\n#![feature(staged_api)]\n#![feature(dropck_parametricity)]\n#![cfg_attr(test, feature(test))]\n\n#![allow(deprecated)]\n\nextern crate alloc;\n\nuse std::cell::{Cell, RefCell};\nuse std::cmp;\nuse std::intrinsics;\nuse std::marker::{PhantomData, Send};\nuse std::mem;\nuse std::ptr;\n\nuse alloc::heap;\nuse alloc::raw_vec::RawVec;\n\n\/\/\/ An arena that can hold objects of only one type.\npub struct TypedArena<T> {\n    \/\/\/ The capacity of the first chunk (once it is allocated).\n    first_chunk_capacity: usize,\n\n    \/\/\/ A pointer to the next object to be allocated.\n    ptr: Cell<*mut T>,\n\n    \/\/\/ A pointer to the end of the allocated area.

Arenas are a type of allocator that destroy the objects within, all at\n\/\/! once, once the arena itself is destroyed. They do not support deallocation\n\/\/! of individual objects while the arena itself is still alive. The benefit\n\/\/! of an arena is very fast allocation; just a pointer bump.\n\/\/!\n\/\/! This crate implements `TypedArena`, a simple arena that can only hold\n\/\/! objects of a single type.\n\n#![crate_name = \"arena\"]\n#![unstable(feature = \"rustc_private\", issue = \"27812\")]\n#![crate_type = \"rlib\"]\n#![crate_type = \"dylib\"]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       test(no_crate_inject, attr(deny(warnings))))]\n#![cfg_attr(not(stage0), deny(warnings))]\n\n#![feature(alloc)]\n#![feature(core_intrinsics)]\n#![feature(heap_api)]\n#![feature(heap_api)]\n#![feature(staged_api)]\n#![feature(dropck_parametricity)]\n#![cfg_attr(test, feature(test))]\n\n#![allow(deprecated)]\n\nextern crate alloc;\n\nuse std::cell::{Cell, RefCell};\nuse std::cmp;\nuse std::intrinsics;\nuse std::marker::{PhantomData, Send};\nuse std::mem;\nuse std::ptr;\n\nuse alloc::heap;\nuse alloc::raw_vec::RawVec;\n\n\/\/\/ An arena that can hold objects of only one type.\npub struct TypedArena<T> {\n    \/\/\/ A pointer to the next object to be allocated.\n    ptr: Cell<*mut T>,\n\n    \/\/\/ A pointer to the end of the allocated area.

Just write\n\/\/\/     the value as if it was imported, e.g. `GET`.\n\/\/\/ *   `name`: A unique name for the endpoint.\n\/\/\/     Generally this will be the same as the containing module.\n\/\/\/ *   `path`: The path component of the URL for the endpoint, e.g. \"\/foo\/bar\".\n\/\/\/     Components of the path that are parameterized can indicate a varible by using a Rust\n\/\/\/     identifier prefixed with a colon, e.g. `\/foo\/:some_parameter`.\n\/\/\/     A corresponding query string parameter will be expected in the request struct (see below\n\/\/\/     for details).\n\/\/\/ *   `rate_limited`: Whether or not the endpoint enforces rate limiting on requests.\n\/\/\/ *   `requires_authentication`: Whether or not the endpoint requires a valid access token.\n\/\/\/\n\/\/\/ ## Request\n\/\/\/\n\/\/\/ The request block contains normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There are also a few special attributes available to control how the struct is converted into a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = \"HEADER_NAME\")]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the request.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/ *   `#[ruma_api(path)]`: Fields with this attribute will be inserted into the matching path\n\/\/\/     component of the request URL.\n\/\/\/ *   `#[ruma_api(query)]`: Fields with this attribute will be inserting into the URL's query\n\/\/\/     string.\n\/\/\/\n\/\/\/ Any field that does not include one of these attributes will be part of the request's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Response\n\/\/\/\n\/\/\/ Like the request block, the response block consists of normal struct field definitions.\n\/\/\/ Doc comments and attributes are allowed as normal.\n\/\/\/ There is also a special attribute available to control how the struct is created from a\n\/\/\/ `http::Request`:\n\/\/\/\n\/\/\/ *   `#[ruma_api(header = \"HEADER_NAME\")]`: Fields with this attribute will be treated as HTTP\n\/\/\/     headers on the response.\n\/\/\/     The value must implement `AsRef<str>`.\n\/\/\/     Generally this is a `String`.\n\/\/\/     The attribute value shown above as `HEADER_NAME` must be a header name constant from\n\/\/\/     `http::header`, e.g. `CONTENT_TYPE`.\n\/\/\/\n\/\/\/ Any field that does not include the above attribute will be expected in the response's JSON\n\/\/\/ body.\n\/\/\/\n\/\/\/ ## Newtype bodies\n\/\/\/\n\/\/\/ Both the request and response block also support \"newtype bodies\" by using the\n\/\/\/ `#[ruma_api(body)]` attribute on a field. If present on a field, the entire request or response\n\/\/\/ body will be treated as the value of the field. This allows you to treat the entire request or\n\/\/\/ response body as a specific type, rather than a JSON object with named fields. Only one field in\n\/\/\/ each struct can be marked with this attribute. It is an error to have a newtype body field and\n\/\/\/ normal body fields within the same struct.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ ```rust,ignore\n\/\/\/ # fn main() {\n\/\/\/ pub mod some_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: GET,\n\/\/\/             name: \"some_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/endpoint\/:baz\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             pub foo: String,\n\/\/\/\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             #[ruma_api(query)]\n\/\/\/             pub bar: String,\n\/\/\/\n\/\/\/             #[ruma_api(path)]\n\/\/\/             pub baz: String,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(header = CONTENT_TYPE)]\n\/\/\/             pub content_type: String,\n\/\/\/\n\/\/\/             pub value: String,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/\n\/\/\/ pub mod newtype_body_endpoint {\n\/\/\/     use ruma_api_macros::ruma_api;\n\/\/\/\n\/\/\/     #[derive(Clone, Debug, Deserialize, Serialize)]\n\/\/\/     pub struct MyCustomType {\n\/\/\/         pub foo: String,\n\/\/\/     }\n\/\/\/\n\/\/\/     ruma_api! {\n\/\/\/         metadata {\n\/\/\/             description: \"Does something.\",\n\/\/\/             method: GET,\n\/\/\/             name: \"newtype_body_endpoint\",\n\/\/\/             path: \"\/_matrix\/some\/newtype\/body\/endpoint\",\n\/\/\/             rate_limited: false,\n\/\/\/             requires_authentication: false,\n\/\/\/         }\n\/\/\/\n\/\/\/         request {\n\/\/\/             #[ruma_api(body)]\n\/\/\/             pub file: Vec<u8>,\n\/\/\/         }\n\/\/\/\n\/\/\/         response {\n\/\/\/             #[ruma_api(body)]\n\/\/\/             pub my_custom_type: MyCustomType,\n\/\/\/         }\n\/\/\/     }\n\/\/\/ }\n\/\/\/ # }\n\/\/\/ ```\n#[proc_macro]\npub fn ruma_api(input: TokenStream) -> TokenStream {\n    let raw_api = syn::parse_macro_input!(input as RawApi);\n\n    let api = Api::from(raw_api);\n\n    api.into_token_stream().into()\n}\n<commit_msg>Disable clippy lint cognitive_complexity for ruma-api-macros<commit_after>\/\/!

{"text":"<commit_before>\/\/! Zero-cost Futures in Rust\n\/\/!\n\/\/! This library is an implementation of futures in Rust which aims to provide\n\/\/! a robust implementation of handling asynchronous computations, ergonomic\n\/\/! composition and usage, and zero-cost abstractions over what would otherwise\n\/\/! be written by hand.\n\/\/!\n\/\/! Futures are a concept for an object which is a proxy for another value that\n\/\/! may not be ready yet. For example issuing an HTTP request may return a\n\/\/! future for the HTTP response, as it probably hasn't arrived yet. With an\n\/\/! object representing a value that will eventually be available, futures allow\n\/\/! for powerful composition of tasks through basic combinators that can perform\n\/\/! operations like chaining computations, changing the types of futures, or\n\/\/! waiting for two futures to complete at the same time.\n\/\/!\n\/\/! ## Installation\n\/\/!\n\/\/! Add this to your `Cargo.toml`:\n\/\/!\n\/\/! ```toml\n\/\/! [dependencies]\n\/\/! futures = \"0.1\"\n\/\/! ```\n\/\/!\n\/\/! ## Examples\n\/\/!\n\/\/! Let's take a look at a few examples of how futures might be used:\n\/\/!\n\/\/! ```\n\/\/! extern crate futures;\n\/\/!\n\/\/! use std::io;\n\/\/! use std::time::Duration;\n\/\/! use futures::{Future, Map};\n\/\/!\n\/\/! \/\/ A future is actually a trait implementation, so we can generically take a\n\/\/! \/\/ future of any integer and return back a future that will resolve to that\n\/\/! \/\/ value plus 10 more.\n\/\/! \/\/\n\/\/! \/\/ Note here that like iterators, we're returning the `Map` combinator in\n\/\/! \/\/ the futures crate, not a boxed abstraction. This is a zero-cost\n\/\/! \/\/ construction of a future.\n\/\/! fn add_ten<F>(future: F) -> Map<F, fn(i32) -> i32>\n\/\/!     where F: Future<Item=i32>,\n\/\/! {\n\/\/!     fn add(a: i32) -> i32 { a + 10 }\n\/\/!     future.map(add)\n\/\/! }\n\/\/!\n\/\/! \/\/ Not only can we modify one future, but we can even compose them together!\n\/\/! \/\/ Here we have a function which takes two futures as input, and returns a\n\/\/! \/\/ future that will calculate the sum of their two values.\n\/\/! \/\/\n\/\/! \/\/ Above we saw a direct return value of the `Map` combinator, but\n\/\/! \/\/ performance isn't always critical and sometimes it's more ergonomic to\n\/\/! \/\/ return a trait object like we do here. Note though that there's only one\n\/\/! \/\/ allocation here, not any for the intermediate futures.\n\/\/! fn add<'a, A, B>(a: A, b: B) -> Box<Future<Item=i32, Error=A::Error> + 'a>\n\/\/!     where A: Future<Item=i32> + 'a,\n\/\/!

Zero-cost Futures in Rust\n\/\/!\n\/\/! This library is an implementation of futures in Rust which aims to provide\n\/\/! a robust implementation of handling asynchronous computations, ergonomic\n\/\/! composition and usage, and zero-cost abstractions over what would otherwise\n\/\/! be written by hand.\n\/\/!\n\/\/! Futures are a concept for an object which is a proxy for another value that\n\/\/! may not be ready yet. For example issuing an HTTP request may return a\n\/\/! future for the HTTP response, as it probably hasn't arrived yet. With an\n\/\/! object representing a value that will eventually be available, futures allow\n\/\/! for powerful composition of tasks through basic combinators that can perform\n\/\/! operations like chaining computations, changing the types of futures, or\n\/\/! waiting for two futures to complete at the same time.\n\/\/!\n\/\/! ## Installation\n\/\/!\n\/\/! Add this to your `Cargo.toml`:\n\/\/!\n\/\/! ```toml\n\/\/! [dependencies]\n\/\/! futures = \"0.1\"\n\/\/! ```\n\/\/!\n\/\/! ## Examples\n\/\/!\n\/\/! Let's take a look at a few examples of how futures might be used:\n\/\/!\n\/\/! ```\n\/\/! extern crate futures;\n\/\/!\n\/\/! use std::io;\n\/\/! use std::time::Duration;\n\/\/! use futures::{Future, Map};\n\/\/!\n\/\/! \/\/ A future is actually a trait implementation, so we can generically take a\n\/\/! \/\/ future of any integer and return back a future that will resolve to that\n\/\/! \/\/ value plus 10 more.\n\/\/! \/\/\n\/\/! \/\/ Note here that like iterators, we're returning the `Map` combinator in\n\/\/! \/\/ the futures crate, not a boxed abstraction. This is a zero-cost\n\/\/! \/\/ construction of a future.\n\/\/! fn add_ten<F>(future: F) -> Map<F, fn(i32) -> i32>\n\/\/!     where F: Future<Item=i32>,\n\/\/! {\n\/\/!     fn add(a: i32) -> i32 { a + 10 }\n\/\/!     future.map(add)\n\/\/! }\n\/\/!\n\/\/! \/\/ Not only can we modify one future, but we can even compose them together!\n\/\/! \/\/ Here we have a function which takes two futures as input, and returns a\n\/\/! \/\/ future that will calculate the sum of their two values.\n\/\/! \/\/\n\/\/! \/\/ Above we saw a direct return value of the `Map` combinator, but\n\/\/! \/\/ performance isn't always critical and sometimes it's more ergonomic to\n\/\/! \/\/ return a trait object like we do here. Note though that there's only one\n\/\/! \/\/ allocation here, not any for the intermediate futures.\n\/\/! fn add<'a, A, B>(a: A, b: B) -> Box<Future<Item=i32, Error=A::Error> + 'a>\n\/\/!     where A: Future<Item=i32> + 'a,\n\/\/!           B: Future<Item=i32, Error=A::Error> + 'a,\n\/\/! {\n\/\/!

Every program imports the prelude by\ndefault.\n\nFor example, it would be annoying to add `use io::println;` to every single\nprogram, and the vast majority of Rust programs will wish to print to standard\noutput. Therefore, it makes sense to import it into every program.\n\nRust's prelude has three main parts:\n\n1. io::print and io::println.\n2. Core operators, such as `Add`, `Mul`, and `Not`.\n3. Various types and traits, such as `Clone`, `Eq`, and `comm::Chan`.\n\n*\/\n\n\n\/\/ Reexported core operators\npub use either::{Either, Left, Right};\npub use kinds::{Const, Copy, Owned, Sized};\npub use ops::{Add, Sub, Mul, Div, Rem, Neg, Not};\npub use ops::{BitAnd, BitOr, BitXor};\npub use ops::{Drop};\npub use ops::{Shl, Shr, Index};\npub use option::{Option, Some, None};\npub use result::{Result, Ok, Err};\n\n\/\/ Reexported functions\npub use io::{print, println};\n\n\/\/ Reexported types and traits\npub use clone::{Clone, DeepClone};\npub use cmp::{Eq, ApproxEq, Ord, TotalEq, TotalOrd, Ordering, Less, Equal, Greater, Equiv};\npub use char::Char;\npub use container::{Container, Mutable, Map, Set};\npub use hash::Hash;\npub use old_iter::{BaseIter, ReverseIter, MutableIter, ExtendedIter, EqIter};\npub use old_iter::{CopyableIter, CopyableOrderedIter, CopyableNonstrictIter};\npub use old_iter::{ExtendedMutableIter};\npub use iter::Times;\npub use num::{Num, NumCast};\npub use num::{Orderable, Signed, Unsigned, Round};\npub use num::{Algebraic, Trigonometric, Exponential, Hyperbolic};\npub use num::{Integer, Fractional, Real, RealExt};\npub use num::{Bitwise, BitCount, Bounded};\npub use num::{Primitive, Int, Float};\npub use path::GenericPath;\npub use path::Path;\npub use path::PosixPath;\npub use path::WindowsPath;\npub use ptr::Ptr;\npub use ascii::{Ascii, AsciiCast, OwnedAsciiCast, AsciiStr};\npub use str::{StrSlice, OwnedStr, StrUtil};\npub use from_str::{FromStr};\npub use to_bytes::IterBytes;\npub use to_str::{ToStr, ToStrConsume};\npub use tuple::{CopyableTuple, ImmutableTuple, ExtendedTupleOps};\npub use tuple::{CloneableTuple2, CloneableTuple3, CloneableTuple4, CloneableTuple5};\npub use tuple::{CloneableTuple6, CloneableTuple7, CloneableTuple8, CloneableTuple9};\npub use tuple::{CloneableTuple10, CloneableTuple11, CloneableTuple12};\npub use tuple::{ImmutableTuple2, ImmutableTuple3, ImmutableTuple4, ImmutableTuple5};\npub use tuple::{ImmutableTuple6, ImmutableTuple7, ImmutableTuple8, ImmutableTuple9};\npub use tuple::{ImmutableTuple10, ImmutableTuple11, ImmutableTuple12};\npub use vec::{CopyableVector, ImmutableVector};\npub use vec::{ImmutableEqVector, ImmutableCopyableVector};\npub use vec::{OwnedVector, OwnedCopyableVector, MutableVector};\npub use io::{Reader, ReaderUtil, Writer, WriterUtil};\n\n\/\/ Reexported runtime types\npub use comm::{stream, Port, Chan, GenericChan, GenericSmartChan, GenericPort, Peekable};\npub use task::spawn;\n\n<|endoftext|>"}

{"text":"<commit_before><commit_msg>comment about PartialEq and Eq trait difference<commit_after>\/\/ Why is this trait called PartialEq?\n\n\/\/ The traditional mathematical definition of an equivalence relation, of which equality is one instance, imposes three requirements.\n\n\/\/ For any values x and y:\n\/\/ • If x == y is true, then y == x must be true as well.\n\/\/   In other words, swapping the two sides of an equality comparison doesn’t affect the result.\n\/\/\n\/\/ • If x == y and y == z, then it must be the case that x == z.\n\/\/   Given any chain of values, each equal to the next, each value in the chain is directly equal to every other.\n\/\/   Equality is contagious.\n\/\/\n\/\/ • It must always be true that x == x.\n\n\/\/ That last requirement might seem too obvious to be worth stating, but this is exactly where things go awry.\n\/\/ Rust’s f32 and f64 are IEEE standard floating-point values.\n\/\/ According to that standard, expressions like 0.0\/0.0 and others with no appropriate value must produce special not-a-number values, usually referred to as NaN values.\n\/\/ The standard further requires that a NaN value be treated as unequal to every other value — including itself.\n\n\/\/ Eq is full equlality constraint.\n\/\/ PartialEq is Eq, but without x == x guarantee.

An instance of `Future`\n\/\/! is handed back to represent that the work may be done later, and futher\n\/\/! computations can be chained along with it as well.\n\/\/!\n\/\/! ```rust\n\/\/! extern crate futures;\n\/\/! extern crate futures_cpupool;\n\/\/!\n\/\/! use std::sync::mpsc::channel;\n\/\/!\n\/\/! use futures::Future;\n\/\/! use futures_cpupool::CpuPool;\n\/\/!\n\/\/! # fn long_running_computation() -> u32 { 2 }\n\/\/! # fn long_running_computation2(a: u32) -> u32 { a }\n\/\/! # fn main() {\n\/\/!\n\/\/! \/\/ Create a worker thread pool with four threads\n\/\/! let pool = CpuPool::new(4);\n\/\/!\n\/\/! \/\/ Execute some work on the thread pool, optionally closing over data.\n\/\/! let a = pool.execute(long_running_computation);\n\/\/! let b = pool.execute(|| long_running_computation2(100));\n\/\/!\n\/\/! \/\/ Express some further computation once the work is completed on the thread\n\/\/! \/\/ pool.\n\/\/! let c = a.join(b).map(|(a, b)| a + b);\n\/\/!\n\/\/! \/\/ Block the current thread to get the result.\n\/\/! let (tx, rx) = channel();\n\/\/! c.then(move |res| {\n\/\/!     tx.send(res)\n\/\/! }).forget();\n\/\/! let res = rx.recv().unwrap();\n\/\/!\n\/\/! \/\/ Print out the result\n\/\/! println!(\"{:?}\", res);\n\/\/! # }\n\/\/! ```\n\n#![deny(missing_docs)]\n\nextern crate crossbeam;\nextern crate futures;\nextern crate num_cpus;\n\nuse std::any::Any;\nuse std::panic::{self, AssertUnwindSafe};\nuse std::sync::Arc;\nuse std::sync::atomic::{AtomicUsize, Ordering};\nuse std::thread;\n\nuse crossbeam::sync::MsQueue;\nuse futures::{Future, oneshot, Oneshot, Poll};\n\n\/\/\/ A thread pool intended to run CPU intensive work.\n\/\/\/\n\/\/\/ This thread pool will hand out futures representing the completed work\n\/\/\/ that happens on the thread pool itself, and the futures can then be later\n\/\/\/ composed with other work as part of an overall computation.\n\/\/\/\n\/\/\/ The worker threads associated with a thread pool are kept alive so long as\n\/\/\/ there is an open handle to the `CpuPool` or there is work running on them.

{"text":"<commit_before>\/\/ Dynamic arenas.\n\n\/\/ Arenas are used to quickly allocate objects that share a\n\/\/ lifetime. The arena uses ~[u8] vectors as a backing store to\n\/\/ allocate objects from. For each allocated object, the arena stores\n\/\/ a pointer to the type descriptor followed by the\n\/\/ object. (Potentially with alignment padding after each of them.)\n\/\/ When the arena is destroyed, it iterates through all of its chunks,\n\/\/ and uses the tydesc information to trace through the objects,\n\/\/ calling the destructors on them.\n\/\/ One subtle point that needs to be addressed is how to handle\n\/\/ failures while running the user provided initializer function. It\n\/\/ is important to not run the destructor on uninitalized objects, but\n\/\/ how to detect them is somewhat subtle. Since alloc() can be invoked\n\/\/ recursively, it is not sufficient to simply exclude the most recent\n\/\/ object. To solve this without requiring extra space, we use the low\n\/\/ order bit of the tydesc pointer to encode whether the object it\n\/\/ describes has been fully initialized.\n\n\/\/ As an optimization, objects with destructors are stored in\n\/\/ different chunks than objects without destructors. This reduces\n\/\/ overhead when initializing plain-old-data and means we don't need\n\/\/ to waste time running the destructors of POD.\n\nexport arena, arena_with_size;\n\nimport list;\nimport list::{list, cons, nil};\nimport unsafe::reinterpret_cast;\nimport sys::TypeDesc;\nimport libc::size_t;\n\n#[abi = \"rust-intrinsic\"]\nextern mod rusti {\n    fn move_val_init<T>(&dst: T, -src: T);\n    fn needs_drop<T>() -> bool;\n}\nextern mod rustrt {\n    #[rust_stack]\n    fn rust_call_tydesc_glue(root: *u8, tydesc: *TypeDesc, field: size_t);\n}\n\/\/ This probably belongs somewhere else.

Same as\n\/\/ above, we want to make sure that the change between rev1 and rev2 also\n\/\/ results in a change of the ICH for the struct's metadata, and that it stays\n\/\/ the same between rev2 and

For background on exception handling and stack unwinding please see\n\/\/! \"Exception Handling in LLVM\" (llvm.org\/docs\/ExceptionHandling.html) and\n\/\/! documents linked from it.\n\/\/! These are also good reads:\n\/\/!     http:\/\/mentorembedded.github.io\/cxx-abi\/abi-eh.html\n\/\/!     http:\/\/monoinfinito.wordpress.com\/series\/exception-handling-in-c\/\n\/\/!     http:\/\/www.airs.com\/blog\/index.php?s=exception+frames\n\/\/!\n\/\/! ## A brief summary\n\/\/!\n\/\/! Exception handling happens in two phases: a search phase and a cleanup phase.\n\/\/!\n\/\/! In both phases the unwinder walks stack frames from top to bottom using\n\/\/! information from the stack frame unwind sections of the current process's\n\/\/! modules (\"module\" here refers to an OS module, i.e. an executable or a\n\/\/! dynamic library).\n\/\/!\n\/\/! For each stack frame, it invokes the associated \"personality routine\", whose\n\/\/! address is also stored in the unwind info section.\n\/\/!\n\/\/! In the search phase, the job of a personality routine is to examine exception\n\/\/! object being thrown, and to decide whether it should be caught at that stack\n\/\/! frame.  Once the handler frame has been identified, cleanup phase begins.\n\/\/!\n\/\/! In the cleanup phase, personality routines invoke cleanup code associated\n\/\/! with their stack frames (i.e. destructors).  Once stack has been unwound down\n\/\/! to the handler frame level, unwinding stops and the last personality routine\n\/\/! transfers control to its catch block.\n\/\/!\n\/\/! ## Frame unwind info registration\n\/\/!\n\/\/! Each module has its own frame unwind info section (usually \".eh_frame\"), and\n\/\/! unwinder needs to know about all of them in order for unwinding to be able to\n\/\/! cross module boundaries.\n\/\/!\n\/\/! On some platforms, like Linux, this is achieved by dynamically enumerating\n\/\/! currently loaded modules via the dl_iterate_phdr() API and finding all\n\/\/! .eh_frame sections.\n\/\/!\n\/\/! Others, like Windows, require modules to actively register their unwind info\n\/\/! sections by calling __register_frame_info() API at startup.  In the latter\n\/\/! case it is essential that there is only one copy of the unwinder runtime in\n\/\/! the process.  This is usually achieved by linking to the dynamic version of\n\/\/! the unwind runtime.\n\/\/!\n\/\/! Currently Rust uses unwind runtime provided by libgcc.\n\n#![allow(dead_code)]\n#![allow(unused_imports)]\n\nuse prelude::v1::*;\n\nuse any::Any;\nuse boxed;\nuse cell::Cell;\nuse cmp;\nuse panicking;\nuse fmt;\nuse intrinsics;\nuse mem;\nuse sync::atomic::{self, Ordering};\nuse sys_common::mutex::Mutex;\n\n\/\/ The actual unwinding implementation is cfg'd here, and we've got two current\n\/\/ implementations.

For background on exception handling and stack unwinding please see\n\/\/! \"Exception Handling in LLVM\" (llvm.org\/docs\/ExceptionHandling.html) and\n\/\/! documents linked from it.\n\/\/! These are also good reads:\n\/\/!     http:\/\/mentorembedded.github.io\/cxx-abi\/abi-eh.html\n\/\/!     http:\/\/monoinfinito.wordpress.com\/series\/exception-handling-in-c\/\n\/\/!     http:\/\/www.airs.com\/blog\/index.php?s=exception+frames\n\/\/!\n\/\/! ## A brief summary\n\/\/!\n\/\/! Exception handling happens in two phases: a search phase and a cleanup phase.\n\/\/!\n\/\/! In both phases the unwinder walks stack frames from top to bottom using\n\/\/! information from the stack frame unwind sections of the current process's\n\/\/! modules (\"module\" here refers to an OS module, i.e. an executable or a\n\/\/! dynamic library).\n\/\/!\n\/\/! For each stack frame, it invokes the associated \"personality routine\", whose\n\/\/! address is also stored in the unwind info section.\n\/\/!\n\/\/! In the search phase, the job of a personality routine is to examine exception\n\/\/! object being thrown, and to decide whether it should be caught at that stack\n\/\/! frame.  Once the handler frame has been identified, cleanup phase begins.\n\/\/!\n\/\/! In the cleanup phase, personality routines invoke cleanup code associated\n\/\/! with their stack frames (i.e. destructors).  Once stack has been unwound down\n\/\/! to the handler frame level, unwinding stops and the last personality routine\n\/\/! transfers control to its catch block.\n\/\/!\n\/\/! ## Frame unwind info registration\n\/\/!\n\/\/! Each module has its own frame unwind info section (usually \".eh_frame\"), and\n\/\/! unwinder needs to know about all of them in order for unwinding to be able to\n\/\/! cross module boundaries.\n\/\/!\n\/\/! On some platforms, like Linux, this is achieved by dynamically enumerating\n\/\/! currently loaded modules via the dl_iterate_phdr() API and finding all\n\/\/! .eh_frame sections.\n\/\/!\n\/\/! Others, like Windows, require modules to actively register their unwind info\n\/\/! sections by calling __register_frame_info() API at startup.  In the latter\n\/\/! case it is essential that there is only one copy of the unwinder runtime in\n\/\/! the process.  This is usually achieved by linking to the dynamic version of\n\/\/! the unwind runtime.\n\/\/!\n\/\/! Currently Rust uses unwind runtime provided by libgcc.\n\n#![allow(dead_code)]\n#![allow(unused_imports)]\n\nuse prelude::v1::*;\n\nuse any::Any;\nuse boxed;\nuse cell::Cell;\nuse cmp;\nuse panicking;\nuse fmt;\nuse intrinsics;\nuse mem;\nuse sync::atomic::{self, Ordering};\nuse sys_common::mutex::Mutex;\n\n\/\/ The actual unwinding implementation is cfg'd here, and we've got two current\n\/\/ implementations.

The unwinding\n\/\/\/   interface for Rust is designed to have at most one try\/catch block per\n\/\/\/   thread, not multiple.

A nested try\/catch block\n\/\/\/   may result in corruption of the outer try\/catch block's state, especially\n\/\/\/   if this is used within a thread itself.\n\/\/\/\n\/\/\/ * It is not sound to trigger unwinding while already unwinding. Rust threads\n\/\/\/   have runtime checks in place to ensure this invariant, but it is not\n\/\/\/   guaranteed that a rust thread is in place when invoking this function.\n\/\/\/   Unwinding twice can lead to resource leaks where some destructors are not\n\/\/\/   run.\npub unsafe fn try<F: FnOnce()>(f: F) -> Result<(), Box<Any + Send>> {\n    let mut f = Some(f);\n    return inner_try(try_fn::<F>, &mut f as *mut _ as *mut u8);\n\n    \/\/ If an inner function were not used here, then this generic function `try`\n    \/\/ uses the native symbol `rust_try`, for which the code is statically\n    \/\/ linked into the standard library.

Rust types can be classified in various useful ways according to\n\/\/! intrinsic properties of the type. These classifications, often called\n\/\/! 'kinds', are represented as traits.\n\/\/!\n\/\/! They cannot be implemented by user code, but are instead implemented\n\/\/! by the compiler automatically for the types to which they apply.\n\n\/\/\/ Types able to be transferred across task boundaries.\n#[lang=\"send\"]\npub trait Send for Sized? : 'static {\n    \/\/ empty.\n}\n\n\/\/\/ Types with a constant size known at compile-time.\n#[lang=\"sized\"]\npub trait Sized for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be copied by simply copying bits (i.e. `memcpy`).\n#[lang=\"copy\"]\npub trait Copy for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be safely shared between tasks when aliased.\n\/\/\/\n\/\/\/ The precise definition is: a type `T` is `Sync` if `&T` is\n\/\/\/ thread-safe. In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

Rust types can be classified in various useful ways according to\n\/\/! intrinsic properties of the type. These classifications, often called\n\/\/! 'kinds', are represented as traits.\n\/\/!\n\/\/! They cannot be implemented by user code, but are instead implemented\n\/\/! by the compiler automatically for the types to which they apply.\n\n\/\/\/ Types able to be transferred across task boundaries.\n#[lang=\"send\"]\npub trait Send for Sized? : 'static {\n    \/\/ empty.\n}\n\n\/\/\/ Types with a constant size known at compile-time.\n#[lang=\"sized\"]\npub trait Sized for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be copied by simply copying bits (i.e. `memcpy`).\n#[lang=\"copy\"]\npub trait Copy for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be safely shared between tasks when aliased.\n\/\/\/\n\/\/\/ The precise definition is: a type `T` is `Sync` if `&T` is\n\/\/\/ thread-safe. In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`marker`](marker\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes the [`ffi`](ffi\/index.html) module for interoperating\n\/\/! with the C language.\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading abstractions.\n\/\/! [`sync`](sync\/index.html) contains further, primitive, shared memory types,\n\/\/! including [`atomic`](sync\/atomic\/index.html), and [`mpsc`](sync\/mpsc\/index.html),\n\/\/! which contains the channel types for message passing.\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets,\n\/\/! timers, and process spawning, are defined in the\n\/\/! [`old_io`](old_io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\/\/ Do not remove on snapshot creation.

The Rust Standard Library provides the essential runtime\n\/\/! functionality for building portable Rust software.\n\/\/! It is linked to all Rust crates by default.\n\/\/!\n\/\/! ## Intrinsic types and operations\n\/\/!\n\/\/! The [`ptr`](ptr\/index.html) and [`mem`](mem\/index.html)\n\/\/! modules deal with unsafe pointers and memory manipulation.\n\/\/! [`marker`](marker\/index.html) defines the special built-in traits,\n\/\/! and [`raw`](raw\/index.html) the runtime representation of Rust types.\n\/\/! These are some of the lowest-level building blocks in Rust.\n\/\/!\n\/\/! ## Math on primitive types and math traits\n\/\/!\n\/\/! Although basic operations on primitive types are implemented\n\/\/! directly by the compiler, the standard library additionally\n\/\/! defines many common operations through traits defined in\n\/\/! mod [`num`](num\/index.html).\n\/\/!\n\/\/! ## Pervasive types\n\/\/!\n\/\/! The [`option`](option\/index.html) and [`result`](result\/index.html)\n\/\/! modules define optional and error-handling types, `Option` and `Result`.\n\/\/! [`iter`](iter\/index.html) defines Rust's iterator protocol\n\/\/! along with a wide variety of iterators.\n\/\/! [`Cell` and `RefCell`](cell\/index.html) are for creating types that\n\/\/! manage their own mutability.\n\/\/!\n\/\/! ## Vectors, slices and strings\n\/\/!\n\/\/! The common container type, `Vec`, a growable vector backed by an array,\n\/\/! lives in the [`vec`](vec\/index.html) module. Contiguous, unsized regions\n\/\/! of memory, `[T]`, commonly called \"slices\", and their borrowed versions,\n\/\/! `&[T]`, commonly called \"borrowed slices\", are built-in types for which the\n\/\/! [`slice`](slice\/index.html) module defines many methods.\n\/\/!\n\/\/! `&str`, a UTF-8 string, is a built-in type, and the standard library\n\/\/! defines methods for it on a variety of traits in the\n\/\/! [`str`](str\/index.html) module. Rust strings are immutable;\n\/\/! use the `String` type defined in [`string`](string\/index.html)\n\/\/! for a mutable string builder.\n\/\/!\n\/\/! For converting to strings use the [`format!`](fmt\/index.html)\n\/\/! macro, and for converting from strings use the\n\/\/! [`FromStr`](str\/trait.FromStr.html) trait.\n\/\/!\n\/\/! ## Platform abstractions\n\/\/!\n\/\/! Besides basic data types, the standard library is largely concerned\n\/\/! with abstracting over differences in common platforms, most notably\n\/\/! Windows and Unix derivatives. The [`os`](os\/index.html) module\n\/\/! provides a number of basic functions for interacting with the\n\/\/! operating environment, including program arguments, environment\n\/\/! variables, and directory navigation. The [`path`](path\/index.html)\n\/\/! module encapsulates the platform-specific rules for dealing\n\/\/! with file paths.\n\/\/!\n\/\/! `std` also includes the [`ffi`](ffi\/index.html) module for interoperating\n\/\/! with the C language.\n\/\/!\n\/\/! ## Concurrency, I\/O, and the runtime\n\/\/!\n\/\/! The [`thread`](thread\/index.html) module contains Rust's threading abstractions.\n\/\/! [`sync`](sync\/index.html) contains further, primitive, shared memory types,\n\/\/! including [`atomic`](sync\/atomic\/index.html), and [`mpsc`](sync\/mpsc\/index.html),\n\/\/! which contains the channel types for message passing.\n\/\/!\n\/\/! Common types of I\/O, including files, TCP, UDP, pipes, Unix domain sockets, and\n\/\/! process spawning, are defined in the [`io`](io\/index.html) module.\n\/\/!\n\/\/! Rust's I\/O and concurrency depends on a small runtime interface\n\/\/! that lives, along with its support code, in mod [`rt`](rt\/index.html).\n\/\/! While a notable part of the standard library's architecture, this\n\/\/! module is not intended for public use.\n\/\/!\n\/\/! ## The Rust prelude and macros\n\/\/!\n\/\/! Finally, the [`prelude`](prelude\/index.html) defines a\n\/\/! common set of traits, types, and functions that are made available\n\/\/! to all code by default. [`macros`](macros\/index.html) contains\n\/\/! all the standard macros, such as `assert!`, `panic!`, `println!`,\n\/\/! and `format!`, also available to all Rust code.\n\/\/ Do not remove on snapshot creation. Needed for bootstrap.

It's most commonly seen when attempting to\nreturn a closure:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be unsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable.

It's most commonly seen when attempting to\nreturn a closure:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(|y| x + y)\n}\n```\n\nNotice that `x` is stack-allocated by `foo()`. By default, Rust captures\nclosed-over data by reference. This means that once `foo()` returns, `x` no\nlonger exists. An attempt to access `x` within the closure would thus be unsafe.\n\nAnother situation where this might be encountered is when spawning threads:\n\n```\nfn foo() {\n    let x = 0u32;\n    let y = 1u32;\n\n    let thr = std::thread::spawn(|| {\n        x + y\n    });\n}\n```\n\nSince our new thread runs in parallel, the stack frame containing `x` and `y`\nmay well have disappeared by the time we try to use them. Even if we call\n`thr.join()` within foo (which blocks until `thr` has completed, ensuring the\nstack frame won't disappear), we will not succeed: the compiler cannot prove\nthat this behaviour is safe, and so won't let us do it.\n\nThe solution to this problem is usually to switch to using a `move` closure.\nThis approach moves (or copies, where possible) data into the closure, rather\nthan taking references to it. For example:\n\n```\nfn foo() -> Box<Fn(u32) -> u32> {\n    let x = 0u32;\n    Box::new(move |y| x + y)\n}\n```\n\nNow that the closure has its own copy of the data, there's no need to worry\nabout safety.\n\"##,\n\nE0381: r##\"\nIt is not allowed to use or capture an uninitialized variable. For example:\n\n```\nfn main() {\n    let x: i32;\n    let y = x; \/\/ error, use of possibly uninitialized variable\n```\n\nTo fix this, ensure that any declared variables are initialized before being\nused.\n\"##,\n\nE0384: r##\"\nThis error occurs when an attempt is made to reassign an immutable variable.\nFor example:\n\n```\nfn main(){\n    let x = 3;\n    x = 5; \/\/ error, reassignment of immutable variable\n}\n```\n\nBy default, variables in Rust are immutable. To fix this error, add the keyword\n`mut` after the keyword `let` when declaring the variable. For example:\n\n```\nfn main(){\n    let mut x = 3;\n    x = 5;\n}\n```\n\"##,\n\nE0387: r##\"\nThis error occurs when an attempt is made to mutate or mutably reference data\nthat a closure has captured immutably. Examples of this error are shown below:\n\n```\n\/\/ Accepts a function or a closure that captures its environment immutably.\n\/\/ Closures passed to foo will not be able to mutate their closed-over state.\nfn foo<F: Fn()>(f: F) { }\n\n\/\/ Attempts to mutate closed-over data.  Error message reads:\n\/\/ `cannot assign to data in a captured outer variable...`\nfn mutable() {\n    let mut x = 0u32;\n    foo(|| x = 2);\n}\n\n\/\/ Attempts to take a mutable reference to closed-over data.  Error message\n\/\/ reads: `cannot borrow data mutably in a captured outer variable...`\nfn mut_addr() {\n    let mut x = 0u32;\n    foo(|| { let y = &mut x; });\n}\n```\n\nThe problem here is that foo is defined as accepting a parameter of type `Fn`.\nClosures passed into foo will thus be inferred to be of type `Fn`, meaning that\nthey capture their context immutably.\n\nThe solution is to capture the data mutably. This can be done by defining `foo`\nto take FnMut rather than Fn:\n\n```\nfn foo<F: FnMut()>(f: F) { }\n```\n\"##\n\n}\n\nregister_diagnostics! {\n    E0382, \/\/ use of partially\/collaterally moved value\n    E0383, \/\/ partial reinitialization of uninitialized structure\n    E0385, \/\/ {} in an aliasable location\n    E0386, \/\/ {} in an immutable container\n    E0388, \/\/ {} in a static location\n    E0389  \/\/ {} in a `&` reference\n}\n<|endoftext|>"}

In other\n\/\/\/ words, each tick of the underlying clock may not be the same length (e.g.\n\/\/\/ some seconds may be longer than others). An instant may jump forwards or\n\/\/\/ experience time dilation (slow down or speed up), but it will never go\n\/\/\/ backwards.\n\/\/\/\n\/\/\/ Instants are opaque types that can only be compared to one another. There is\n\/\/\/ no method to get \"the number of seconds\" from an instant. Instead, it only\n\/\/\/ allows measuring the duration between two instants (or comparing two\n\/\/\/ instants).\n\/\/\/\n\/\/\/ Example:\n\/\/\/\n\/\/\/ ```no_run\n\/\/\/ use std::time::{Duration, Instant};\n\/\/\/ use std::thread::sleep;\n\/\/\/\n\/\/\/ fn main() {\n\/\/\/    let now = Instant::now();\n\/\/\/\n\/\/\/    \/\/ we sleep for 2 seconds\n\/\/\/    sleep(Duration::new(2, 0));\n\/\/\/    \/\/ it prints '2'\n\/\/\/    println!(\"{}\", now.elapsed().as_secs());\n\/\/\/ }\n\/\/\/ ```\n#[derive(Copy, Clone, PartialEq, Eq, PartialOrd, Ord)]\n#[stable(feature = \"time2\", since = \"1.8.0\")]\npub struct Instant(time::Instant);\n\n\/\/\/ A measurement of the system clock, useful for talking to\n\/\/\/ external entities like the file system or other processes.\n\/\/\/\n\/\/\/ Distinct from the `Instant` type, this time measurement **is not\n\/\/\/ monotonic**. This means that you can save a file to the file system, then\n\/\/\/ save another file to the file system, **and the second file has a\n\/\/\/ `SystemTime` measurement earlier than the second**. In other words, an\n\/\/\/ operation that happens after another operation in real time may have an\n\/\/\/ earlier `SystemTime`!\n\/\/\/\n\/\/\/ Consequently, comparing two `SystemTime` instances to learn about the\n\/\/\/ duration between them returns a `Result` instead of an infallible `Duration`\n\/\/\/ to indicate that this sort of time drift may happen and needs to be handled.\n\/\/\/\n\/\/\/ Although a `SystemTime` cannot be directly inspected, the `UNIX_EPOCH`\n\/\/\/ constant is provided in this module as an anchor in time to learn\n\/\/\/ information about a `SystemTime`.

Texture creation and modification.\n\/\/!\n\/\/! \"Texture\" is an overloaded term. In gfx-rs, a texture consists of two\n\/\/! separate pieces of information: image storage description (which is\n\/\/! immutable for a single texture object), and image data. To actually use a\n\/\/! texture, a \"sampler\" is needed, which provides a way of accessing the\n\/\/! image data.  Image data consists of an array of \"texture elements\", or\n\/\/! texels.\n\nuse std::default::Default;\n\n\/\/\/ How to [filter](https:\/\/en.wikipedia.org\/wiki\/Texture_filtering) the\n\/\/\/ texture when sampling. They correspond to increasing levels of quality,\n\/\/\/ but also cost. They \"layer\" on top of each other: it is not possible to\n\/\/\/ have bilinear filtering without mipmapping, for example.\n\/\/\/\n\/\/\/ These names are somewhat poor, in that \"bilinear\" is really just doing\n\/\/\/ linear filtering on each axis, and it is only bilinear in the case of 2D\n\/\/\/ textures. Similarly for trilinear, it is really Quadralinear(?) for 3D\n\/\/\/ textures. Alas, these names are simple, and match certain intuitions\n\/\/\/ ingrained by many years of public use of inaccurate terminology.\n#[deriving(Eq, Ord, PartialEq, PartialOrd, Hash, Clone, Show)]\npub enum FilterMethod {\n    \/\/\/ The dumbest filtering possible, nearest-neighbor interpolation.\n    Scale,\n    \/\/\/ Add simple mipmapping.\n    Mipmap,\n    \/\/\/ Sample multiple texels within a single mipmap level to increase\n    \/\/\/ quality.\n    Bilinear,\n    \/\/\/ Sample multiple texels across two mipmap levels to increase quality.\n    Trilinear,\n    \/\/\/ Anisotropic filtering with a given \"max\", must be between 1 and 16,\n    \/\/\/ inclusive.\n    Anisotropic(u8)\n}\n\n\/\/\/ Specifies how a given texture may be used.

It is not possible\n\/\/\/ to move out of borrowed strings because they are owned elsewhere.\n\/\/\/\n\/\/\/ # Examples\n\/\/\/\n\/\/\/ Here's some code that uses a `&str`:\n\/\/\/\n\/\/\/ ```\n\/\/\/ let s = \"Hello, world.\";\n\/\/\/ ```\n\/\/\/\n\/\/\/ This `&str` is a `&'static str`, which is the type of string literals.\n\/\/\/ They're `'static` because literals are available for the entire lifetime of\n\/\/\/ the program.\n\/\/\/\n\/\/\/ You can get a non-`'static` `&str` by taking a slice of a `String`:\n\/\/\/\n\/\/\/ ```\n\/\/\/ let some_string = \"Hello, world.\".to_string();\n\/\/\/ let s = &some_string;\n\/\/\/ ```\n\/\/\/\n\/\/\/ # Representation\n\/\/\/\n\/\/\/ Rust's string type, `str`, is a sequence of Unicode scalar values encoded as\n\/\/\/ a stream of UTF-8 bytes. All [strings](..\/..\/reference.html#literals) are\n\/\/\/ guaranteed to be validly encoded UTF-8 sequences. Additionally, strings are\n\/\/\/ not null-terminated and can thus contain null bytes.\n\/\/\/\n\/\/\/ The actual representation of `str`s have direct mappings to slices: `&str`\n\/\/\/ is the same as `&[u8]`.\n\/\/\/\n\/\/\/ *[See also the `std::str` module](str\/index.html).*\n\/\/\/\nmod prim_str { }\n\n#[doc(primitive = \"tuple\")]\n\/\/\n\/\/\/ A finite heterogeneous sequence, `(T, U, ..)`.\n\/\/\/\n\/\/\/ To access the _N_-th element of a tuple one can use `N` itself\n\/\/\/ as a field of the tuple.\n\/\/\/\n\/\/\/ Indexing starts from zero, so `0` returns first value, `1`\n\/\/\/ returns second value, and so on.

Traits for working with Errors.\n\/\/!\n\/\/! # The `Error` trait\n\/\/!\n\/\/! `Error` is a trait representing the basic expectations for error values,\n\/\/! i.e. values of type `E` in `Result<T, E>`. At a minimum, errors must provide\n\/\/! a description, but they may optionally provide additional detail (via\n\/\/! `Display`) and cause chain information:\n\/\/!\n\/\/! ```\n\/\/! use std::fmt::Display;\n\/\/!\n\/\/! trait Error: Display {\n\/\/!     fn description(&self) -> &str;\n\/\/!\n\/\/!     fn cause(&self) -> Option<&Error> { None }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! The `cause` method is generally used when errors cross \"abstraction\n\/\/! boundaries\", i.e.  when a one module must report an error that is \"caused\"\n\/\/! by an error from a lower-level module. This setup makes it possible for the\n\/\/! high-level module to provide its own errors that do not commit to any\n\/\/! particular implementation, but also reveal some of its implementation for\n\/\/! debugging via `cause` chains.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/ A note about crates and the facade:\n\/\/\n\/\/ Originally, the `Error` trait was defined in libcore, and the impls\n\/\/ were scattered about. However, coherence objected to this\n\/\/ arrangement, because to create the blanket impls for `Box` required\n\/\/ knowing that `&str: !Error`, and we have no means to deal with that\n\/\/ sort of conflict just now. Therefore, for the time being, we have\n\/\/ moved the `Error` trait into libstd. As we evolve a sol'n to the\n\/\/ coherence challenge (e.g., specialization, neg impls, etc) we can\n\/\/ reconsider what crate these items belong in.\n\nuse any::TypeId;\nuse boxed::Box;\nuse

Traits for working with Errors.\n\/\/!\n\/\/! # The `Error` trait\n\/\/!\n\/\/! `Error` is a trait representing the basic expectations for error values,\n\/\/! i.e. values of type `E` in `Result<T, E>`. At a minimum, errors must provide\n\/\/! a description, but they may optionally provide additional detail (via\n\/\/! `Display`) and cause chain information:\n\/\/!\n\/\/! ```\n\/\/! use std::fmt::Display;\n\/\/!\n\/\/! trait Error: Display {\n\/\/!     fn description(&self) -> &str;\n\/\/!\n\/\/!     fn cause(&self) -> Option<&Error> { None }\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! The `cause` method is generally used when errors cross \"abstraction\n\/\/! boundaries\", i.e.  when a one module must report an error that is \"caused\"\n\/\/! by an error from a lower-level module. This setup makes it possible for the\n\/\/! high-level module to provide its own errors that do not commit to any\n\/\/! particular implementation, but also reveal some of its implementation for\n\/\/! debugging via `cause` chains.\n\n#![stable(feature = \"rust1\", since = \"1.0.0\")]\n\n\/\/ A note about crates and the facade:\n\/\/\n\/\/ Originally, the `Error` trait was defined in libcore, and the impls\n\/\/ were scattered about. However, coherence objected to this\n\/\/ arrangement, because to create the blanket impls for `Box` required\n\/\/ knowing that `&str: !Error`, and we have no means to deal with that\n\/\/ sort of conflict just now. Therefore, for the time being, we have\n\/\/ moved the `Error` trait into libstd. As we evolve a sol'n to the\n\/\/ coherence challenge (e.g., specialization, neg impls, etc) we can\n\/\/ reconsider what crate these items belong in.\n\nuse any::TypeId;\nuse boxed::Box;\nuse

{"text":"<commit_before>\/*!\nA uniform is a global variable in your program. In order to draw something, you will need to\ngive `glium` the values of all your uniforms. Objects that implement the `Uniform` trait are\nhere to do that.\n\nThere are two primarly ways to do this. The first one is to create your own structure and put\nthe `#[uniforms]` attribute on it. See the `glium_macros` crate for more infos.\n\nThe second way is to use the `uniform!` macro provided by glium:\n\n```no_run\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let tex: f32 = unsafe { std::mem::uninitialized() };\n# let matrix: f32 = unsafe { std::mem::uninitialized() };\nlet uniforms = uniform! {\n    texture: tex,\n    matrix: matrix\n};\n# }\n```\n\nIn both situations, each field must implement the `UniformValue` trait.\n\n## Samplers\n\nIn order to customize the way a texture is being sampled, you must use a `Sampler`.\n\n```no_run\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\nlet uniforms = uniform! {\n    texture: glium::uniforms::Sampler::new(&texture)\n                        .magnify_filter(glium::uniforms::MagnifySamplerFilter::Nearest)\n};\n# }\n```\n\n## Blocks\n\nIn GLSL, you can choose to use a uniform *block*. When you use a block, you first need to\nupload the content of this block in the video memory thanks to a `UniformBuffer`. Then you\ncan link the buffer to the name of the block, just like any other uniform.\n\n```no_run\n#[macro_use]\nextern crate glium;\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\n\nlet program = glium::Program::from_source(&display,\n    \"\n        #version 110\n\n        attribute vec2 position;\n\n        void main() {\n            gl_Position = vec4(position, 0.0, 1.0);\n        }\n    \",\n    \"\n        #version 330\n        uniform layout(std140);\n\n        uniform MyBlock {\n            vec3 color;\n        };\n\n        void main() {\n            gl_FragColor = vec4(color, 1.0);\n        }\n    \",\n    None);\n\nlet buffer = glium::uniforms::UniformBuffer::new(&display, (0.5f32, 0.5f32, 0.5f32)).unwrap();\n\nlet uniforms = uniform! {\n    MyBlock: &buffer\n};\n# }\n```\n\n## Subroutines\nTODO\n*\/\npub use

uniform module documentation with subroutines<commit_after>\/*!\nA uniform is a global variable in your program. In order to draw something, you will need to\ngive `glium` the values of all your uniforms. Objects that implement the `Uniform` trait are\nhere to do that.\n\nThere are two primarly ways to do this. The first one is to create your own structure and put\nthe `#[uniforms]` attribute on it. See the `glium_macros` crate for more infos.\n\nThe second way is to use the `uniform!` macro provided by glium:\n\n```no_run\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let tex: f32 = unsafe { std::mem::uninitialized() };\n# let matrix: f32 = unsafe { std::mem::uninitialized() };\nlet uniforms = uniform! {\n    texture: tex,\n    matrix: matrix\n};\n# }\n```\n\nIn both situations, each field must implement the `UniformValue` trait.\n\n## Samplers\n\nIn order to customize the way a texture is being sampled, you must use a `Sampler`.\n\n```no_run\n#[macro_use]\nextern crate glium;\n\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\nlet uniforms = uniform! {\n    texture: glium::uniforms::Sampler::new(&texture)\n                        .magnify_filter(glium::uniforms::MagnifySamplerFilter::Nearest)\n};\n# }\n```\n\n## Blocks\n\nIn GLSL, you can choose to use a uniform *block*. When you use a block, you first need to\nupload the content of this block in the video memory thanks to a `UniformBuffer`. Then you\ncan link the buffer to the name of the block, just like any other uniform.\n\n```no_run\n#[macro_use]\nextern crate glium;\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\n\nlet program = glium::Program::from_source(&display,\n    \"\n        #version 110\n\n        attribute vec2 position;\n\n        void main() {\n            gl_Position = vec4(position, 0.0, 1.0);\n        }\n    \",\n    \"\n        #version 330\n        uniform layout(std140);\n\n        uniform MyBlock {\n            vec3 color;\n        };\n\n        void main() {\n            gl_FragColor = vec4(color, 1.0);\n        }\n    \",\n    None);\n\nlet buffer = glium::uniforms::UniformBuffer::new(&display, (0.5f32, 0.5f32, 0.5f32)).unwrap();\n\nlet uniforms = uniform! {\n    MyBlock: &buffer\n};\n# }\n```\n\n## Subroutines\nOpenGL allows the use of subroutines, which are like function pointers. Subroutines can be used\nto change the functionality of a shader program at runtime. This method is usually a lot faster\nthan using multiple programs that are switched during execution.\n\nA subroutine uniform is unique per shader stage, and not per program.\n\n```no_run\n#[macro_use]\nextern crate glium;\n# fn main() {\n# let display: glium::Display = unsafe { std::mem::uninitialized() };\n# let texture: glium::texture::Texture2d = unsafe { std::mem::uninitialized() };\n\nlet program = glium::Program::from_source(&display,\n    \"\n        #version 150\n        in vec2 position;\n        void main() {\n            gl_Position = vec4(position, 0.0, 1.0);\n        }\n    \",\n    \"\n        #version 150\n        #extension GL_ARB_shader_subroutine : require\n        out vec4 fragColor;\n        subroutine vec4 modify_t(vec4 color);\n        subroutine uniform modify_t modify_color;\n\n        subroutine(modify_t) vec4 delete_r(vec4 color)\n        {\n          return vec4(0, color.g, color.b, color.a);\n        }\n\n        subroutine(modify_t) vec4 delete_b(vec4 color)\n        {\n          return vec4(color.r, color.g, 0, color.a);\n        }\n\n        void main()\n        {\n            vec4 white= vec4(1, 1, 1, 1);\n            fragColor = modify_color(white);\n        }\n    \", None);\n\n    let uniforms = uniform! {\n        modify_color: (\"delete_b\", glium::program::ShaderStage::Fragment)\n    };\n#

The easiest way to\n\/\/! create a mesh is to use the `#[vertex_format]` attribute on a struct, upload them into a\n\/\/! `Buffer`, and then use `Mesh::from`.\n\nuse device;\nuse device::attrib;\n\n\/\/\/ Describes a single attribute of a vertex buffer, including its type, name, etc.\n#[deriving(Clone, PartialEq, Show)]\npub struct Attribute {\n    \/\/\/ A name to match the shader input\n    pub name: String,\n    \/\/\/ Vertex buffer to contain the data\n    pub buffer: device::RawBufferHandle,\n    \/\/\/ Format of the attribute\n    pub format: attrib::Format,\n}\n\n\/\/\/ A trait implemented automatically for user vertex structure by\n\/\/\/ `#[vertex_format] attribute\npub trait VertexFormat {\n    \/\/\/ Create the attributes for this type, using the given buffer.\n    fn generate(Option<Self>, buffer: device::RawBufferHandle) -> Vec<Attribute>;\n}\n\n\/\/\/ Describes geometry to render.\n#[deriving(Clone, PartialEq, Show)]\npub struct Mesh {\n    \/\/\/ Number of vertices in the mesh.\n    pub num_vertices: device::VertexCount,\n    \/\/\/ Vertex attributes to use.\n    pub attributes: Vec<Attribute>,\n}\n\nimpl Mesh {\n    \/\/\/ Create a new mesh, which is a `TriangleList` with no attributes and `nv` vertices.\n    pub fn new(nv: device::VertexCount) -> Mesh {\n        Mesh {\n            num_vertices: nv,\n            attributes: Vec::new(),\n        }\n    }\n\n    \/\/\/ Create a new `Mesh` from a struct that implements `VertexFormat` and a buffer.\n    pub fn from_format<V: VertexFormat>(buf: device::BufferHandle<V>, nv: device::VertexCount) -> Mesh {\n        Mesh {\n            num_vertices: nv,\n            attributes: VertexFormat::generate(None::<V>, buf.raw()),\n        }\n    }\n\n    \/\/\/ Create a new intanced `Mesh` given a vertex buffer and an instance buffer.\n    pub fn from_format_instanced<V: VertexFormat, U: VertexFormat>(\n                                 buf: device::BufferHandle<V>, nv: device::VertexCount,\n                                 inst: device::BufferHandle<U>) -> Mesh {\n        let per_vertex   = VertexFormat::generate(None::<V>, buf.raw());\n        let per_instance = VertexFormat::generate(None::<U>, inst.raw());\n\n        let mut attributes = per_vertex;\n        for mut at in per_instance.move_iter() {\n            at.format.instance_rate = 1;\n            attributes.push(at);\n        }\n\n        Mesh {\n            num_vertices: nv,\n            attributes: attributes,\n        }\n    }\n\n    \/\/\/ Return a vertex slice of the whole mesh\n    pub fn get_slice(&self, pt: device::PrimitiveType) -> Slice {\n        VertexSlice(pt, 0, self.num_vertices)\n    }\n}\n\n\/\/\/ Description of a subset of `Mesh` data to render.\n\/\/\/ We provide a primitive type in a slice because it is how we interpret mesh\n\/\/\/ contents.

For other types copies must be made\nexplicitly, by convention implementing the `Clone` trait and calling\nthe `clone` method.\n\n*\/\n\n#![unstable]\n\n\/\/\/ A common trait for cloning an object.\npub trait Clone {\n    \/\/\/ Returns a copy of the value.\n    fn clone(&self) -> Self;\n\n    \/\/\/ Perform copy-assignment from `source`.\n    \/\/\/\n    \/\/\/ `a.clone_from(&b)` is equivalent to `a = b.clone()` in functionality,\n    \/\/\/ but can be overridden to reuse the resources of `a` to avoid unnecessary\n    \/\/\/ allocations.\n    #[inline(always)]\n    #[experimental = \"this function is mostly unused\"]\n    fn clone_from(&mut self, source: &Self) {\n        *self = source.clone()\n    }\n}\n\nimpl<'a, T> Clone for &'a T {\n    \/\/\/ Return a shallow copy of the reference.\n    #[inline]\n    fn clone(&self) -> &'a T { *self }\n}\n\nimpl<'a, T> Clone for &'a [T] {\n    \/\/\/ Return a shallow copy of the slice.\n    #[inline]\n    fn clone(&self) -> &'a [T] { *self }\n}\n\nimpl<'a> Clone for &'a str {\n    \/\/\/ Return a shallow copy of the slice.\n    #[inline]\n    fn clone(&self) -> &'a str { *self }\n}\n\nmacro_rules! clone_impl(\n    ($t:ty) => {\n        impl Clone for $t {\n            \/\/\/ Return a deep copy of the value.\n            #[inline]\n            fn clone(&self) -> $t { *self }\n        }\n    }\n)\n\nclone_impl!(int)\nclone_impl!(i8)\nclone_impl!(i16)\nclone_impl!(i32)\nclone_impl!(i64)\n\nclone_impl!(uint)\nclone_impl!(u8)\nclone_impl!(u16)\nclone_impl!(u32)\nclone_impl!(u64)\n\nclone_impl!(f32)\nclone_impl!(f64)\n\nclone_impl!(())\nclone_impl!(bool)\nclone_impl!(char)\n\nmacro_rules! extern_fn_clone(\n    ($($A:ident),*) => (\n        #[experimental = \"this may not be sufficient for fns with region parameters\"]\n        impl<$($A,)* ReturnType> Clone for extern \"Rust\" fn($($A),*) -> ReturnType {\n            \/\/\/ Return a copy of a function pointer\n            #[inline]\n            fn clone(&self) -> extern \"Rust\" fn($($A),*) -> ReturnType { *self }\n        }\n    )\n)\n\nextern_fn_clone!()\nextern_fn_clone!(A)\nextern_fn_clone!(A, B)\nextern_fn_clone!(A, B, C)\nextern_fn_clone!(A, B, C, D)\nextern_fn_clone!(A, B, C, D, E)\nextern_fn_clone!(A, B, C, D, E, F)\nextern_fn_clone!(A, B, C, D, E, F, G)\nextern_fn_clone!(A, B, C, D, E, F, G, H)\n\n<|endoftext|>"}

They cannot be implemented by user code, but are instead implemented\n\/\/! by the compiler automatically for the types to which they apply.\n\n\/\/\/ Types able to be transferred across task boundaries.\n#[lang=\"send\"]\npub trait Send for Sized? : 'static {\n    \/\/ empty.\n}\n\n\/\/\/ Types with a constant size known at compile-time.\n#[lang=\"sized\"]\npub trait Sized for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be copied by simply copying bits (i.e. `memcpy`).\n#[lang=\"copy\"]\npub trait Copy for Sized? {\n    \/\/ Empty.\n}\n\n\/\/\/ Types that can be safely shared between tasks when aliased.\n\/\/\/\n\/\/\/ The precise definition is: a type `T` is `Sync` if `&T` is\n\/\/\/ thread-safe. In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::kinds::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.  Any types with\n\/\/\/ interior mutability must also use the `std::cell::UnsafeCell` wrapper\n\/\/\/ around the value(s) which can be mutated when behind a `&`\n\/\/\/ reference; not doing this is undefined behaviour (for example,\n\/\/\/ `transmute`-ing from `&T` to `&mut T` is illegal).\n#[lang=\"sync\"]\npub trait Sync for Sized? {\n    \/\/ Empty\n}\n\n\/\/\/ Marker types are special types that are used with unsafe code to\n\/\/\/ inform the compiler of special constraints.

In\n    \/\/\/ this case, it is ok to substitute a larger lifetime for `'a`\n    \/\/\/ (e.g., `fn(&'static T)`), because the function is only\n    \/\/\/ becoming more selective in terms of what it accepts as\n    \/\/\/ argument.\n    \/\/\/\n    \/\/\/ For more information about variance, refer to this Wikipedia\n    \/\/\/ article <http:\/\/en.wikipedia.org\/wiki\/Variance_%28computer_science%29>.\n    #[lang=\"covariant_lifetime\"]\n    #[deriving(Clone, PartialEq, Eq, PartialOrd, Ord)]\n    pub struct CovariantLifetime<'a>;\n\n    impl<'a> Copy for CovariantLifetime<'a> {}\n\n    \/\/\/ As `ContravariantType`, but for lifetime parameters.

In safe code\nit is impossible to create an instance of an empty type, so empty match\nexpressions are almost never desired.  This error is typically fixed by adding\none or more cases to the match expression.\n\nAn example of an empty type is `enum Empty { }`.\n\"##,\n\nE0003: r##\"\nNot-a-Number (NaN) values cannot be compared for equality and hence can never\nmatch the input to a match expression. To match against NaN values, you should\ninstead use the `is_nan` method in a guard, as in: x if x.is_nan() => ...\n\"##,\n\nE0004: r##\"\nThis error indicates that the compiler cannot guarantee a matching pattern for\none or more possible inputs to a match expression. Guaranteed matches are\nrequired in order to assign values to match expressions, or alternatively,\ndetermine the flow of execution.\n\nIf you encounter this error you must alter your patterns so that every possible\nvalue of the input type is matched. For types with a small number of variants\n(like enums) you should probably cover all cases explicitly. Alternatively, the\nunderscore `_` wildcard pattern can be added after all other patterns to match\n\"anything else\".\n\"##,\n\n\/\/ FIXME: Remove duplication here?\nE0005: r##\"\nPatterns used to bind names must be irrefutable, that is, they must guarantee that a\nname will be extracted in all cases. If you encounter this error you probably need\nto use a `match` or `if let` to deal with the possibility of failure.\n\"##,\n\nE0006: r##\"\nPatterns used to bind names must be irrefutable, that is, they must guarantee that a\nname will be extracted in all cases. If you encounter this error you probably need\nto use a `match` or `if let` to deal with the possibility of failure.\n\"##,\n\nE0007: r##\"\nThis error indicates that the bindings in a match arm would require a value to\nbe moved into more than one location, thus violating unique ownership. Code like\nthe following is invalid as it requires the entire Option<String> to be moved\ninto a variable called `op_string` while simultaneously requiring the inner\nString to be moved into a variable called `s`.\n\nlet x = Some(\"s\".to_string());\nmatch x {\n    op_string @ Some(s) => ...\n    None => ...\n}\n\nSee also Error 303.\n\"##,\n\nE0008: r##\"\nNames bound in match arms retain their type in pattern guards. As such, if a\nname is bound by move in a pattern, it should also be moved to wherever it is\nreferenced in the pattern guard code. Doing so however would prevent the name\nfrom being available in the body of the match arm. Consider the following:\n\nmatch Some(\"hi\".to_string()) {\n    Some(s) if s.len() == 0 => \/\/ use s.\n    ...\n}\n\nThe variable `s` has type String, and its use in the guard is as a variable of\ntype String. The guard code effectively executes in a separate scope to the body\nof the arm, so the value would be moved into this anonymous scope and therefore\nbecome unavailable in the body of the arm. Although this example seems\ninnocuous, the problem is most clear when considering functions that take their\nargument by value.\n\nmatch Some(\"hi\".to_string()) {\n    Some(s) if { drop(s); false } => (),\n    Some(s) => \/\/ use s.\n    ...\n}\n\nThe value would be dropped in the guard then become unavailable not only in the\nbody of that arm but also in all subsequent arms! The solution is to bind by\nreference when using guards or refactor the entire expression, perhaps by\nputting the condition inside the body of the arm.\n\"##,\n\nE0152: r##\"\nLang items are already implemented in the standard library. Unless you are\nwriting a free-standing application (e.g. a kernel), you do not need to provide\nthem yourself.\n\nYou can build a free-standing crate by adding `#![no_std]` to the crate\nattributes:\n\n#![feature(no_std)]\n#![no_std]\n\nSee also https:\/\/doc.rust-lang.org\/book\/no-stdlib.html\n\"##,\n\nE0158: r##\"\n`const` and `static` mean different things. A `const` is a compile-time\nconstant, an alias for a literal value. This property means you can match it\ndirectly within a pattern.\n\nThe `static` keyword, on the other hand, guarantees a fixed location in memory.\nThis does not always mean that the value is constant.

In safe code\nit is impossible to create an instance of an empty type, so empty match\nexpressions are almost never desired.  This error is typically fixed by adding\none or more cases to the match expression.\n\nAn example of an empty type is `enum Empty { }`.\n\"##,\n\nE0003: r##\"\nNot-a-Number (NaN) values cannot be compared for equality and hence can never\nmatch the input to a match expression. To match against NaN values, you should\ninstead use the `is_nan` method in a guard, as in: x if x.is_nan() => ...\n\"##,\n\nE0004: r##\"\nThis error indicates that the compiler cannot guarantee a matching pattern for\none or more possible inputs to a match expression. Guaranteed matches are\nrequired in order to assign values to match expressions, or alternatively,\ndetermine the flow of execution.\n\nIf you encounter this error you must alter your patterns so that every possible\nvalue of the input type is matched. For types with a small number of variants\n(like enums) you should probably cover all cases explicitly. Alternatively, the\nunderscore `_` wildcard pattern can be added after all other patterns to match\n\"anything else\".\n\"##,\n\n\/\/ FIXME: Remove duplication here?\nE0005: r##\"\nPatterns used to bind names must be irrefutable, that is, they must guarantee that a\nname will be extracted in all cases. If you encounter this error you probably need\nto use a `match` or `if let` to deal with the possibility of failure.\n\"##,\n\nE0006: r##\"\nPatterns used to bind names must be irrefutable, that is, they must guarantee that a\nname will be extracted in all cases. If you encounter this error you probably need\nto use a `match` or `if let` to deal with the possibility of failure.\n\"##,\n\nE0007: r##\"\nThis error indicates that the bindings in a match arm would require a value to\nbe moved into more than one location, thus violating unique ownership. Code like\nthe following is invalid as it requires the entire Option<String> to be moved\ninto a variable called `op_string` while simultaneously requiring the inner\nString to be moved into a variable called `s`.\n\nlet x = Some(\"s\".to_string());\nmatch x {\n    op_string @ Some(s) => ...\n    None => ...\n}\n\nSee also Error 303.\n\"##,\n\nE0008: r##\"\nNames bound in match arms retain their type in pattern guards. As such, if a\nname is bound by move in a pattern, it should also be moved to wherever it is\nreferenced in the pattern guard code. Doing so however would prevent the name\nfrom being available in the body of the match arm. Consider the following:\n\nmatch Some(\"hi\".to_string()) {\n    Some(s) if s.len() == 0 => \/\/ use s.\n    ...\n}\n\nThe variable `s` has type String, and its use in the guard is as a variable of\ntype String. The guard code effectively executes in a separate scope to the body\nof the arm, so the value would be moved into this anonymous scope and therefore\nbecome unavailable in the body of the arm. Although this example seems\ninnocuous, the problem is most clear when considering functions that take their\nargument by value.\n\nmatch Some(\"hi\".to_string()) {\n    Some(s) if { drop(s); false } => (),\n    Some(s) => \/\/ use s.\n    ...\n}\n\nThe value would be dropped in the guard then become unavailable not only in the\nbody of that arm but also in all subsequent arms! The solution is to bind by\nreference when using guards or refactor the entire expression, perhaps by\nputting the condition inside the body of the arm.\n\"##,\n\nE0152: r##\"\nLang items are already implemented in the standard library. Unless you are\nwriting a free-standing application (e.g. a kernel), you do not need to provide\nthem yourself.\n\nYou can build a free-standing crate by adding `#![no_std]` to the crate\nattributes:\n\n#![feature(no_std)]\n#![no_std]\n\nSee also https:\/\/doc.rust-lang.org\/book\/no-stdlib.html\n\"##,\n\nE0158: r##\"\n`const` and `static` mean different things. A `const` is a compile-time\nconstant, an alias for a literal value. This property means you can match it\ndirectly within a pattern.\n\nThe `static` keyword, on the other hand, guarantees a fixed location in memory.\nThis does not always mean that the value is constant. For example, a global\nmutex can be declared `static` as well.\n\nIf you want to match against a `static`, consider using a guard instead:\n\nstatic FORTY_TWO: i32 = 42;\nmatch Some(42) {\n    Some(x) if x == FORTY_TWO => ...\n    ...\n}\n\"##,\n\nE0161: r##\"\nIn Rust, you can only move a value when its size is known at compile time.\n\nTo work around this restriction, consider \"hiding\" the value behind a reference:\neither `&x` or `&mut x`.

In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.

In other words, there is no possibility of data races\n\/\/\/ when passing `&T` references between tasks.\n\/\/\/\n\/\/\/ As one would expect, primitive types like `u8` and `f64` are all\n\/\/\/ `Sync`, and so are simple aggregate types containing them (like\n\/\/\/ tuples, structs and enums). More instances of basic `Sync` types\n\/\/\/ include \"immutable\" types like `&T` and those with simple\n\/\/\/ inherited mutability, such as `Box<T>`, `Vec<T>` and most other\n\/\/\/ collection types. (Generic parameters need to be `Sync` for their\n\/\/\/ container to be `Sync`.)\n\/\/\/\n\/\/\/ A somewhat surprising consequence of the definition is `&mut T` is\n\/\/\/ `Sync` (if `T` is `Sync`) even though it seems that it might\n\/\/\/ provide unsynchronised mutation. The trick is a mutable reference\n\/\/\/ stored in an aliasable reference (that is, `& &mut T`) becomes\n\/\/\/ read-only, as if it were a `& &T`, hence there is no risk of a data\n\/\/\/ race.\n\/\/\/\n\/\/\/ Types that are not `Sync` are those that have \"interior\n\/\/\/ mutability\" in a non-thread-safe way, such as `Cell` and `RefCell`\n\/\/\/ in `std::cell`. These types allow for mutation of their contents\n\/\/\/ even when in an immutable, aliasable slot, e.g. the contents of\n\/\/\/ `&Cell<T>` can be `.set`, and do not ensure data races are\n\/\/\/ impossible, hence they cannot be `Sync`. A higher level example\n\/\/\/ of a non-`Sync` type is the reference counted pointer\n\/\/\/ `std::rc::Rc`, because any reference `&Rc<T>` can clone a new\n\/\/\/ reference, which modifies the reference counts in a non-atomic\n\/\/\/ way.\n\/\/\/\n\/\/\/ For cases when one does need thread-safe interior mutability,\n\/\/\/ types like the atomics in `std::sync` and `Mutex` & `RWLock` in\n\/\/\/ the `sync` crate do ensure that any mutation cannot cause data\n\/\/\/ races.  Hence these types are `Sync`.\n\/\/\/\n\/\/\/ Users writing their own types with interior mutability (or anything\n\/\/\/ else that is not thread-safe) should use the `NoSync` marker type\n\/\/\/ (from `std::marker`) to ensure that the compiler doesn't\n\/\/\/ consider the user-defined type to be `Sync`.

This module provides utilities to handle data across non-Rust\n\/\/! interfaces, like other programming languages and the underlying\n\/\/! operating system.  It is mainly of use for FFI (Foreign Function\n\/\/! Interface) bindings and code that needs to exchange C-like strings\n\/\/! with other languages.\n\/\/!\n\/\/! # Overview\n\/\/!\n\/\/! Rust represents owned strings with the [`String`] type, and\n\/\/! borrowed slices of strings with the [`str`] primitive.  Both are\n\/\/! always in UTF-8 encoding, and may contain nul bytes in the middle,\n\/\/! i.e. if you look at the bytes that make up the string, there may\n\/\/! be a `\\0` among them.  Both `String` and `str` store their length\n\/\/! explicitly; there are no nul terminators at the end of strings\n\/\/! like in C.\n\/\/!\n\/\/! C strings are different from Rust strings:\n\/\/!\n\/\/! * **Encodings** - Rust strings are UTF-8, but C strings may use\n\/\/! other encodings.  If you are using a string from C, you should\n\/\/! check its encoding explicitly, rather than just assuming that it\n\/\/! is UTF-8 like you can do in Rust.\n\/\/!\n\/\/! * **Character size** - C strings may use `char` or `wchar_t`-sized\n\/\/! characters; please **note** that C's `char` is different from Rust's.\n\/\/! The C standard leaves the actual sizes of those types open to\n\/\/! interpretation, but defines different APIs for strings made up of\n\/\/! each character type.  Rust strings are always UTF-8, so different\n\/\/! Unicode characters will be encoded in a variable number of bytes\n\/\/! each.  The Rust type [`char`] represents a '[Unicode scalar\n\/\/! value]', which is similar to, but not the same as, a '[Unicode\n\/\/! code point]'.\n\/\/!\n\/\/! * **Nul terminators and implicit string lengths** - Often, C\n\/\/! strings are nul-terminated, i.e. they have a `\\0` character at the\n\/\/! end.  The length of a string buffer is not stored, but has to be\n\/\/! calculated; to compute the length of a string, C code must\n\/\/! manually call a function like `strlen()` for `char`-based strings,\n\/\/! or `wcslen()` for `wchar_t`-based ones.  Those functions return\n\/\/! the number of characters in the string excluding the nul\n\/\/! terminator, so the buffer length is really `len+1` characters.\n\/\/! Rust strings don't have a nul terminator; their length is always\n\/\/! stored and does not need to be calculated.  While in Rust\n\/\/! accessing a string's length is a O(1) operation (becasue the\n\/\/! length is stored); in C it is an O(length) operation because the\n\/\/! length needs to be computed by scanning the string for the nul\n\/\/! terminator.\n\/\/!\n\/\/! * **Internal nul characters** - When C strings have a nul\n\/\/! terminator character, this usually means that they cannot have nul\n\/\/! characters in the middle — a nul character would essentially\n\/\/! truncate the string.  Rust strings *can* have nul characters in\n\/\/! the middle, because nul does not have to mark the end of the\n\/\/! string in Rust.\n\/\/!\n\/\/! # Representations of non-Rust strings\n\/\/!\n\/\/! [`CString`] and [`CStr`] are useful when you need to transfer\n\/\/! UTF-8 strings to and from languages with a C ABI, like Python.\n\/\/!\n\/\/! * **From Rust to C:** [`CString`] represents an owned, C-friendly\n\/\/! string: it is nul-terminated, and has no internal nul characters.\n\/\/! Rust code can create a `CString` out of a normal string (provided\n\/\/! that the string doesn't have nul characters in the middle), and\n\/\/! then use a variety of methods to obtain a raw `*mut u8` that can\n\/\/! then be passed as an argument to functions which use the C\n\/\/! conventions for strings.\n\/\/!\n\/\/! * **From C to Rust:** [`CStr`] represents a borrowed C string; it\n\/\/! is what you would use to wrap a raw `*const u8` that you got from\n\/\/! a C function.  A `CStr` is guaranteed to be a nul-terminated array\n\/\/! of bytes.  Once you have a `CStr`, you can convert it to a Rust\n\/\/! `&str` if it's valid UTF-8, or lossily convert it by adding\n\/\/! replacement characters.\n\/\/!\n\/\/! [`OsString`] and [`OsStr`] are useful when you need to transfer\n\/\/! strings to and from the operating system itself, or when capturing\n\/\/! the output of external commands.  Conversions between `OsString`,\n\/\/! `OsStr` and Rust strings work similarly to those for [`CString`]\n\/\/! and [`CStr`].\n\/\/!\n\/\/! * [`OsString`] represents an owned string in whatever\n\/\/! representation the operating system prefers.  In the Rust standard\n\/\/! library, various APIs that transfer strings to\/from the operating\n\/\/! system use `OsString` instead of plain strings.  For example,\n\/\/! [`env::var_os()`] is used to query environment variables; it\n\/\/! returns an `Option<OsString>`.  If the environment variable exists\n\/\/! you will get a `Some(os_string)`, which you can *then* try to\n\/\/! convert to a Rust string.  This yields a [`Result<>`], so that\n\/\/! your code can detect errors in case the environment variable did\n\/\/! not in fact contain valid Unicode data.\n\/\/!\n\/\/! * [`OsStr`] represents a borrowed reference to a string in a\n\/\/! format that can be passed to the operating system.  It can be\n\/\/! converted into an UTF-8 Rust string slice in a similar way to\n\/\/! `OsString`.\n\/\/!\n\/\/! # Conversions\n\/\/!\n\/\/! ## On Unix\n\/\/!\n\/\/! On Unix, [`OsStr`] implements the\n\/\/! `std::os::unix:ffi::`[`OsStrExt`][unix.OsStrExt] trait, which\n\/\/! augments it with two methods, [`from_bytes`] and [`as_bytes`].\n\/\/! These do inexpensive conversions from and to UTF-8 byte slices.\n\/\/!\n\/\/! Additionally, on Unix [`OsString`] implements the\n\/\/! `std::os::unix:ffi::`[`OsStringExt`][unix.OsStringExt] trait,\n\/\/! which provides [`from_vec`] and [`into_vec`] methods that consume\n\/\/! their arguments, and take or produce vectors of [`u8`].\n\/\/!\n\/\/! ## On Windows\n\/\/!\n\/\/! On Windows, [`OsStr`] implements the\n\/\/! `std::os::windows::ffi::`[`OsStrExt`][windows.OsStrExt] trait,\n\/\/! which provides an [`encode_wide`] method.  This provides an\n\/\/! iterator that can be [`collect`]ed into a vector of [`u16`].\n\/\/!\n\/\/! Additionally, on Windows [`OsString`] implements the\n\/\/! `std::os::windows:ffi::`[`OsStringExt`][windows.OsStringExt]\n\/\/! trait, which provides a [`from_wide`] method.  The result of this\n\/\/! method is an `OsString` which can be round-tripped to a Windows\n\/\/! string losslessly.\n\/\/!\n\/\/! [`String`]: ..\/string\/struct.String.html\n\/\/!

The `ToOwned` trait generalizes `Clone` to construct owned data\n\/\/\/ from any borrow of a given type.\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\npub trait ToOwned {\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    type Owned: Borrow<Self>;\n\n    \/\/\/ Creates owned data from borrowed data, usually by cloning.\n    \/\/\/\n    \/\/\/ # Examples\n    \/\/\/\n    \/\/\/ Basic usage:\n    \/\/\/\n    \/\/\/ ```\n    \/\/\/ let s = \"a\"; \/\/ &str\n    \/\/\/ let ss = s.to_owned(); \/\/ String\n    \/\/\/\n    \/\/\/ let v = &[1, 2]; \/\/ slice\n    \/\/\/ let vv = v.to_owned(); \/\/ Vec\n    \/\/\/ ```\n    #[stable(feature = \"rust1\", since = \"1.0.0\")]\n    fn to_owned(&self) -> Self::Owned;\n}\n\n#[stable(feature = \"rust1\", since = \"1.0.0\")]\nimpl<T> ToOwned for T where T: Clone {\n    type Owned = T;\n    fn to_owned(&self) -> T {\n        self.clone()\n    }\n}\n\n\/\/\/ A clone-on-write smart pointer.\n\/\/\/\n\/\/\/ The type `Cow` is a smart pointer providing clone-on-write functionality: it\n\/\/\/ can enclose and provide immutable access to borrowed data, and clone the\n\/\/\/ data lazily when mutation or ownership is required. The type is designed to\n\/\/\/ work with general borrowed data via the `Borrow` trait.\n\/\/\/\n\/\/\/ `Cow` implements `Deref`, which means that you can call\n\/\/\/ non-mutating methods directly on the data it encloses.

In order to track changes to the build graph and nodes, we need to persist\n\/\/! the graph to disk. Each invocation of the build must read this in and do a\n\/\/! comparison to figure out what has changed since the last run.\n\/\/!\n\/\/! The persistent storage needs to store the following types of data:\n\/\/!\n\/\/!  1. **Nodes**\n\/\/!\n\/\/!     This is a generic data type and can be subdivided into two main types:\n\/\/!\n\/\/!      (a) Resources\n\/\/!      (b) Tasks\n\/\/!\n\/\/!     It should be possible to generically serialize these into a single SQL\n\/\/!     table. We are only interested in storing the node *identifiers* here.\n\/\/!     State associated with resources is stored in a separate table for\n\/\/!     reasons described later.\n\/\/!\n\/\/!     It may be better to split the resources and tasks into separate tables\n\/\/!     to further ensure that the graph remains bipartite. Note that, if this\n\/\/!     is done, the `edges` table and `pending` table must also be split up.\n\/\/!\n\/\/!  2. **Edges**\n\/\/!\n\/\/!     The edges between nodes must also be stored. This table is pretty\n\/\/!     trivial. We only need to store a pair of node IDs and some data\n\/\/!     associated with the edge (e.g., if it is an implicit or explicit edge).\n\/\/!\n\/\/!  3. **Resource State**\n\/\/!\n\/\/!     The resource state can be \"Unknown\", \"Missing\", or a 32-byte array. It\n\/\/!     is up to the implementation of the resource how the bytes in the array\n\/\/!     are interpreted. Most of the time, this will probably be a SHA256 hash.\n\/\/!     However, the 32-byte array can be packed however the implementation\n\/\/!     wishes. For example, tracking changes by timestamp may just choose to\n\/\/!     pack the buffer with a 64-bit timestamp, 64-bit length, and fill the\n\/\/!     rest with zeroes. In such a case, computing the checksum would be\n\/\/!     computationally wasteful.\n\/\/!\n\/\/!     Thus, this table is very simple: a node ID and a 32-byte array.\n\/\/!\n\/\/!     The first row in this table is special. It is the state of the build\n\/\/!     description. This is to avoid loading the build description if it hasn't\n\/\/!     changed.\n\/\/!\n\/\/!  4. **Pending Nodes**\n\/\/!\n\/\/!     This table shall contain a list of nodes that must be visited upon the\n\/\/!     next graph traversal. To understand why this is needed, consider the\n\/\/!     following scenario:\n\/\/!\n\/\/!      1. An initial build is started.\n\/\/!      2. The build fails.\n\/\/!      3. We fix the problem.\n\/\/!      4. We run the build again.\n\/\/!\n\/\/!     Now, we expect that only the failed tasks will get executed, not the\n\/\/!     entire build. Between steps (1) and (2), a number of important things\n\/\/!     must happen:\n\/\/!\n\/\/!      1. The stored build state is loaded from the database and into a graph\n\/\/!         data structure.\n\/\/!      2. The graph constructed from the list of rules is merged into the\n\/\/!         graph from (1). We do this by figuring out the \"diff\" between the\n\/\/!         two graphs (i.e., added\/removed nodes and edges). Any new nodes must\n\/\/!         be visited in the build graph traversal.\n\/\/!      3. The updated build state is committed to disk.\n\/\/!\n\/\/!     After this point, the build can fail or get `kill -9`'d and things\n\/\/!     should be fine. However, the build system must not forget which nodes\n\/\/!     need to be visited in the traversal.\n\n\n\/\/\/ The storage medium for the build system that persists between builds,\n\/\/\/ implemented as a SQLite database. Also known as the build state.\n\/\/\/\n\/\/\/ The main operations we are interested in with this database are:\n\/\/\/\n\/\/\/  1. Loading or creating a database if it doesn't exist.\n\/\/\/  2. Adding nodes and edges\n\/\/\/  3. Creating a graph from the nodes and edges.\n\/\/\/  4. Getting the state associated with a node.\n\/\/\/  5. Getting the list of pending nodes.\n\/\/\/\nstruct Database {\n    \/\/ TODO:\n}\n<|endoftext|>"}

This library provides smart pointers and collections for managing\n\/\/! heap-allocated values.\n\/\/!\n\/\/! This library, like libcore, normally doesn’t need to be used directly\n\/\/! since its contents are re-exported in the [`std` crate](..\/std\/index.html).\n\/\/! Crates that use the `#![no_std]` attribute however will typically\n\/\/! not depend on `std`, so they’d use this crate instead.\n\/\/!\n\/\/! ## Boxed values\n\/\/!\n\/\/! The [`Box`](boxed\/index.html) type is a smart pointer type. There can\n\/\/! only be one owner of a `Box`, and the owner can decide to mutate the\n\/\/! contents, which live on the heap.\n\/\/!\n\/\/! This type can be sent among threads efficiently as the size of a `Box` value\n\/\/! is the same as that of a pointer. Tree-like data structures are often built\n\/\/! with boxes because each node often has only one owner, the parent.\n\/\/!\n\/\/! ## Reference counted pointers\n\/\/!\n\/\/! The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a thread. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](sync\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This type allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Collections\n\/\/!\n\/\/! Implementations of the most common general purpose data structures are\n\/\/! defined in this library. They are re-exported through the\n\/\/! [standard collections library](..\/std\/collections\/index.html).\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/!

The [`Rc`](rc\/index.html) type is a non-threadsafe reference-counted pointer\n\/\/! type intended for sharing memory within a thread. An `Rc` pointer wraps a\n\/\/! type, `T`, and only allows access to `&T`, a shared reference.\n\/\/!\n\/\/! This type is useful when inherited mutability (such as using `Box`) is too\n\/\/! constraining for an application, and is often paired with the `Cell` or\n\/\/! `RefCell` types in order to allow mutation.\n\/\/!\n\/\/! ## Atomically reference counted pointers\n\/\/!\n\/\/! The [`Arc`](sync\/index.html) type is the threadsafe equivalent of the `Rc`\n\/\/! type. It provides all the same functionality of `Rc`, except it requires\n\/\/! that the contained type `T` is shareable. Additionally, `Arc<T>` is itself\n\/\/! sendable while `Rc<T>` is not.\n\/\/!\n\/\/! This type allows for shared access to the contained data, and is often\n\/\/! paired with synchronization primitives such as mutexes to allow mutation of\n\/\/! shared resources.\n\/\/!\n\/\/! ## Collections\n\/\/!\n\/\/! Implementations of the most common general purpose data structures are\n\/\/! defined in this library. They are re-exported through the\n\/\/! [standard collections library](..\/std\/collections\/index.html).\n\/\/!\n\/\/! ## Heap interfaces\n\/\/!\n\/\/! The [`alloc`](alloc\/index.html) module defines the low-level interface to the\n\/\/! default global allocator. It is not compatible with the libc allocator API.\n\n#![allow(unused_attributes)]\n#![unstable(feature = \"alloc\",\n            reason = \"this library is unlikely to be stabilized in its current \\\n                      form or name\",\n            issue = \"27783\")]\n#![doc(html_logo_url = \"https:\/\/www.rust-lang.org\/logos\/rust-logo-128x128-blk-v2.png\",\n       html_favicon_url = \"https:\/\/doc.rust-lang.org\/favicon.ico\",\n       html_root_url = \"https:\/\/doc.rust-lang.org\/nightly\/\",\n       issue_tracker_base_url = \"https:\/\/github.com\/rust-lang\/rust\/issues\/\",\n       test(no_crate_inject, attr(allow(unused_variables), deny(warnings))))]\n#![no_std]\n#![needs_allocator]\n#![deny(missing_debug_implementations)]\n\n#![cfg_attr(not(test), feature(fn_traits))]\n#![cfg_attr(not(test), feature(generator_trait))]\n#![cfg_attr(not(stage0), feature(nll))]\n#![cfg_attr(test, feature(test))]\n\n#![feature(allocator_api)]\n#![feature(allow_internal_unstable)]\n#![feature(arbitrary_self_types)]\n#![feature(box_into_raw_non_null)]\n#![feature(box_patterns)]\n#![feature(box_syntax)]\n#![feature(cfg_target_has_atomic)]\n#![feature(coerce_unsized)]\n#![feature(const_fn)]\n#![feature(core_intrinsics)]\n#![feature(custom_attribute)]\n#![feature(dropck_eyepatch)]\n#![feature(exact_size_is_empty)]\n#![feature(fmt_internals)]\n#![feature(fundamental)]\n#![feature(futures_api)]\n#![feature(lang_items)]\n#![feature(libc)]\n#![feature(needs_allocator)]\n#![feature(optin_builtin_traits)]\n#![feature(pattern)]\n#![feature(pin)]\n#![feature(ptr_internals)]\n#![feature(ptr_offset_from)]\n#![feature(rustc_attrs)]\n#![feature(specialization)]\n#![feature(split_ascii_whitespace)]\n#![feature(staged_api)]\n#![feature(str_internals)]\n#![feature(trusted_len)]\n#![feature(try_reserve)]\n#![feature(unboxed_closures)]\n#![feature(unicode_internals)]\n#![feature(unsize)]\n#![feature(allocator_internals)]\n#![feature(on_unimplemented)]\n#![feature(exact_chunks)]\n#![feature(rustc_const_unstable)]\n#![feature(const_vec_new)]\n\n\/\/ Allow testing this library\n\n#[cfg(test)]\n#[macro_use]\nextern crate std;\n#[cfg(test)]\nextern crate test;\n#[cfg(test)]\nextern crate rand;\n\n\/\/ Module with internal macros used by other modules (needs to be included before other modules).\n#[macro_use]\nmod macros;\n\n\/\/ Heaps provided for low-level allocation strategies\n\npub mod alloc;\n\n#[unstable(feature = \"futures_api\",\n           reason = \"futures in libcore are unstable\",\n           issue = \"50547\")]\npub mod task;\n\/\/ Primitive types using the heaps above\n\n\/\/ Need to conditionally define the mod from `boxed.rs` to avoid\n\/\/ duplicating the lang-items when building in test cfg; but also need\n\/\/ to allow code to have `use boxed::Box;` declarations.\n#[cfg(not(test))]\npub mod boxed;\n#[cfg(test)]\nmod boxed {\n    pub use std::boxed::Box;\n}\n#[cfg(test)]\nmod boxed_test;\npub mod collections;\n#[cfg(all(target_has_atomic = \"ptr\", target_has_atomic = \"cas\"))]\npub mod sync;\npub mod rc;\npub mod raw_vec;\npub mod prelude;\npub mod borrow;\npub mod fmt;\npub mod slice;\npub mod str;\npub mod string;\npub mod vec;\n\n#[cfg(not(test))]\nmod std {\n    pub use core::ops;      \/\/ RangeFull\n}\n<|endoftext|>"}

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested up into inputs and\n* outputs, and subdivides those into declared (input) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase. Even when a function's\n* work-doing part (the \"exec\" phase) never gets called, it has declared\n* inputs, which can be checked for freshness (and potentially\n* used to determine that the function can be skipped).\n*\n* The workcache checks _all_ works for freshness, but uses the set of\n* discovered outputs from the _previous_ exec (which it will re-discover\n* and re-record each time the exec phase runs).\n*\n* Therefore the discovered works cached in the db might be a\n* mis-approximation of the current discoverable works, but this is ok for\n* the following reason: we assume that if an artifact A changed from\n* depending on B,C,D to depending on B,C,D,E, then A itself changed (as\n* part of the change-in-dependencies), so we will be ok.\n*\n* Each function has a single discriminated output work called its _result_.\n* This is only different from other works in that it is returned, by value,\n* from a call to the cacheable function; the other output works are used in\n* passing to invalidate dependencies elsewhere in the cache, but do not\n* otherwise escape from a function invocation. Most functions only have one\n* output work anyways.\n*\n* A database (the central store of a workcache) stores a mappings:\n*\n* (fn_name,{declared_input}) => ({discovered_input},\n*                                {discovered_output},result)\n*\n* (Note: fbuild, which workcache is based on, has the concept of a declared\n* output as separate from a discovered output. This distinction exists only\n* as an artifact of how fbuild works: via annotations on function types\n* and metaprogramming, with explicit dependency declaration as a fallback.\n* Workcache is more explicit about dependencies, and as such treats all\n* outputs the same, as discovered-during-the-last-run.)\n*\n*\/\n\n#[deriving(Eq)]\n#[auto_encode]\n#[auto_decode]\nstruct WorkKey {\n    kind:

That is, it's _just_ a mechanism for describing cached\n* functions. This makes it much simpler and smaller than a \"build system\"\n* that produces an IR and evaluates it. The evaluation order is normal\n* function calls. Some of them just return really quickly.\n*\n* A cached function consumes and produces a set of _works_. A work has a\n* name, a kind (that determines how the value is to be checked for\n* freshness) and a value. Works must also be (de)serializable. Some\n* examples of works:\n*\n*    kind   name    value\n*   ------------------------\n*    cfg    os      linux\n*    file   foo.c   <sha1>\n*    url    foo.com <etag>\n*\n* Works are conceptually single units, but we store them most of the time\n* in maps of the form (type,name) => value. These are WorkMaps.\n*\n* A cached function divides the works it's interested up into inputs and\n* outputs, and subdivides those into declared (input) works and\n* discovered (input and output) works.\n*\n* A _declared_ input or is one that is given to the workcache before\n* any work actually happens, in the \"prep\" phase. Even when a function's\n* work-doing part (the \"exec\" phase) never gets called, it has declared\n* inputs, which can be checked for freshness (and potentially\n* used to determine that the function can be skipped).\n*\n* The workcache checks _all_ works for freshness, but uses the set of\n* discovered outputs from the _previous_ exec (which it will re-discover\n* and re-record each time the exec phase runs).\n*\n* Therefore the discovered works cached in the db might be a\n* mis-approximation of the current discoverable works, but this is ok for\n* the following reason: we assume that if an artifact A changed from\n* depending on B,C,D to depending on B,C,D,E, then A itself changed (as\n* part of the change-in-dependencies), so we will be ok.\n*\n* Each function has a single discriminated output work called its _result_.\n* This is only different from other works in that it is returned, by value,\n* from a call to the cacheable function; the other output works are used in\n* passing to invalidate dependencies elsewhere in the cache, but do not\n* otherwise escape from a function invocation. Most functions only have one\n* output work anyways.\n*\n* A database (the central store of a workcache) stores a mappings:\n*\n* (fn_name,{declared_input}) => ({discovered_input},\n*                                {discovered_output},result)\n*\n* (Note: fbuild, which workcache is based on, has the concept of a declared\n* output as separate from a discovered output. This distinction exists only\n* as an artifact of how fbuild works: via annotations on function types\n* and metaprogramming, with explicit dependency declaration as a fallback.\n* Workcache is more explicit about dependencies, and as such treats all\n* outputs the same, as discovered-during-the-last-run.)\n*\n*\/\n\n#[deriving(Eq)]\n#[auto_encode]\n#[auto_decode]\nstruct WorkKey {\n    kind:

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/! The `Clone` trait for types that cannot be 'implicitly copied'.\n\/\/!\n\/\/! In Rust, some simple types are \"implicitly copyable\" and when you\n\/\/! assign them or pass them as arguments, the receiver will get a copy,\n\/\/! leaving the original value in place. These types do not require\n\/\/! allocation to copy and do not have finalizers (i.e. they do not\n\/\/! contain owned boxes or implement `Drop`), so the compiler considers\n\/\/! them cheap and safe to copy. For other types copies must be made\n\/\/! explicitly, by convention implementing the `Clone` trait and calling\n\/\/! the `clone` method.\n\/\/!\n\/\/!

In Rust, some simple types are \"implicitly copyable\" and when you\n\/\/! assign them or pass them as arguments, the receiver will get a copy,\n\/\/! leaving the original value in place. These types do not require\n\/\/! allocation to copy and do not have finalizers (i.e. they do not\n\/\/! contain owned boxes or implement `Drop`), so the compiler considers\n\/\/! them cheap and safe to copy. For other types copies must be made\n\/\/! explicitly, by convention implementing the `Clone` trait and calling\n\/\/! the `clone` method.\n\/\/!\n\/\/! Basic usage example:\n\/\/!\n\/\/! ```\n\/\/! let s = String::new(); \/\/ String type implements Clone\n\/\/! let copy = s.clone(); \/\/ so we can clone it\n\/\/! ```\n\/\/!\n\/\/!

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/\/ Formatting of chained expressions, i.e. expressions which are chained by\n\/\/\/ dots: struct and enum field access and method calls.\n\/\/\/\n\/\/\/ Instead of walking these subexpressions one-by-one, as is our usual strategy\n\/\/\/ for expression formatting, we collect maximal sequences of these expressions\n\/\/\/ and handle them simultaneously.\n\/\/\/\n\/\/\/ Whenever possible, the entire chain is put on a single line. If that fails,\n\/\/\/ we put each subexpression on a separate, much like the (default) function\n\/\/\/ argument function argument strategy.\n\/\/\/\n\/\/\/ Depends on config options: `chain_base_indent` is the indent to use for\n\/\/\/ blocks in the parent\/root\/base of the chain.\n\/\/\/ E.g., `let foo = { aaaa; bbb; ccc }.bar.baz();`, we would layout for the\n\/\/\/ following values of `chain_base_indent`:\n\/\/\/ Visual:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/               aaaa;\n\/\/\/               bbb;\n\/\/\/               ccc\n\/\/\/           }\n\/\/\/           .bar\n\/\/\/           .baz();\n\/\/\/ ```\n\/\/\/ Inherit:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/     aaaa;\n\/\/\/     bbb;\n\/\/\/     ccc\n\/\/\/ }\n\/\/\/ .bar\n\/\/\/ .baz();\n\/\/\/ ```\n\/\/\/ Tabbed:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/         aaaa;\n\/\/\/         bbb;\n\/\/\/         ccc\n\/\/\/     }\n\/\/\/     .bar\n\/\/\/     .baz();\n\/\/\/ ```\n\/\/\/\n\/\/\/ `chain_indent` dictates how the rest of the chain is aligned. This only seems\n\/\/\/ to have an effect if the first non-root part of the chain is put on a\n\/\/\/ newline, otherwise we align the dots:\n\/\/\/ ```\n\/\/\/ foo.bar\n\/\/\/    .baz()\n\/\/\/ ```\n\/\/\/ If the first item in the chain is a block expression, we align the dots with\n\/\/\/ the braces.\n\/\/\/\n\/\/\/ Otherwise:\n\/\/\/ Visual:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/             .bar\n\/\/\/             .baz()\n\/\/\/ ```\n\/\/\/ Visual seems to be a tab indented from the indent of the whole expression.\n\/\/\/ Inherit:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/ .bar\n\/\/\/ .baz()\n\/\/\/ ```\n\/\/\/ Tabbed:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/     .bar\n\/\/\/     .baz()\n\/\/\/ ```\n\/\/\/ `chains_overflow_last` applies only to chains where the last item is a\n\/\/\/ method call. Usually, any line break in a chain sub-expression causes the\n\/\/\/ whole chain to be split with newlines at each `.`. With `chains_overflow_last`\n\/\/\/ true, then we allow the last method call to spill over multiple lines without\n\/\/\/ forcing the rest of the chain to be split.\n\n\nuse Indent;\nuse rewrite::{Rewrite, RewriteContext};\nuse utils::{wrap_str, first_line_width};\nuse expr::rewrite_call;\nuse config::BlockIndentStyle;\n\nuse syntax::{ast, ptr};\nuse syntax::codemap::{mk_sp, Span};\n\n\npub fn rewrite_chain(expr: &ast::Expr,\n                     context: &RewriteContext,\n                     width: usize,\n                     offset: Indent)\n                     -> Option<String> {\n    let total_span = expr.span;\n    let (parent, subexpr_list) = make_subexpr_list(expr);\n\n    \/\/ Parent is the first item in the chain, e.g., `foo` in `foo.bar.baz()`.\n    let parent_block_indent = chain_base_indent(context, offset);\n    let parent_context = &RewriteContext { block_indent: parent_block_indent, ..*context };\n    let parent_rewrite = try_opt!(parent.rewrite(parent_context, width, offset));\n\n    \/\/ Decide how to layout the rest of the chain. `extend` is true if we can\n    \/\/ put the first non-parent item on the same line as the parent.\n    let (indent, extend) = if !parent_rewrite.contains('\\n') && is_continuable(parent) ||\n                              parent_rewrite.len() <= context.config.tab_spaces {\n        \/\/ Try and put the whole chain on one line.\n        (offset + Indent::new(0, parent_rewrite.len()), true)\n    } else if is_block_expr(parent, &parent_rewrite) {\n        \/\/ The parent is a block, so align the rest of the chain with the closing\n        \/\/ brace.\n        (parent_block_indent, false)\n    } else {\n        (chain_indent(context, offset), false)\n    };\n\n    let max_width = try_opt!((width + offset.width()).checked_sub(indent.width()));\n    let mut rewrites = try_opt!(subexpr_list.iter()\n                                            .rev()\n                                            .map(|e| {\n                                                rewrite_chain_subexpr(e,\n                                                                      total_span,\n                                                                      context,\n                                                                      max_width,\n                                                                      indent)\n                                            })\n                                            .collect::<Option<Vec<_>>>());\n\n    \/\/ Total of all items excluding the last.\n    let almost_total = rewrites[..rewrites.len() - 1]\n                           .iter()\n                           .fold(0, |a, b| a + first_line_width(b)) +\n                       parent_rewrite.len();\n    let total_width = almost_total + first_line_width(rewrites.last().unwrap());\n\n    let veto_single_line = if context.config.take_source_hints && subexpr_list.len() > 1 {\n        \/\/ Look at the source code.

This file may not be copied, modified, or distributed\n\/\/ except according to those terms.\n\n\/\/\/ Formatting of chained expressions, i.e. expressions which are chained by\n\/\/\/ dots: struct and enum field access and method calls.\n\/\/\/\n\/\/\/ Instead of walking these subexpressions one-by-one, as is our usual strategy\n\/\/\/ for expression formatting, we collect maximal sequences of these expressions\n\/\/\/ and handle them simultaneously.\n\/\/\/\n\/\/\/ Whenever possible, the entire chain is put on a single line. If that fails,\n\/\/\/ we put each subexpression on a separate, much like the (default) function\n\/\/\/ argument function argument strategy.\n\/\/\/\n\/\/\/ Depends on config options: `chain_base_indent` is the indent to use for\n\/\/\/ blocks in the parent\/root\/base of the chain.\n\/\/\/ E.g., `let foo = { aaaa; bbb; ccc }.bar.baz();`, we would layout for the\n\/\/\/ following values of `chain_base_indent`:\n\/\/\/ Visual:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/               aaaa;\n\/\/\/               bbb;\n\/\/\/               ccc\n\/\/\/           }\n\/\/\/           .bar\n\/\/\/           .baz();\n\/\/\/ ```\n\/\/\/ Inherit:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/     aaaa;\n\/\/\/     bbb;\n\/\/\/     ccc\n\/\/\/ }\n\/\/\/ .bar\n\/\/\/ .baz();\n\/\/\/ ```\n\/\/\/ Tabbed:\n\/\/\/ ```\n\/\/\/ let foo = {\n\/\/\/         aaaa;\n\/\/\/         bbb;\n\/\/\/         ccc\n\/\/\/     }\n\/\/\/     .bar\n\/\/\/     .baz();\n\/\/\/ ```\n\/\/\/\n\/\/\/ `chain_indent` dictates how the rest of the chain is aligned. This only seems\n\/\/\/ to have an effect if the first non-root part of the chain is put on a\n\/\/\/ newline, otherwise we align the dots:\n\/\/\/ ```\n\/\/\/ foo.bar\n\/\/\/    .baz()\n\/\/\/ ```\n\/\/\/ If the first item in the chain is a block expression, we align the dots with\n\/\/\/ the braces.\n\/\/\/\n\/\/\/ Otherwise:\n\/\/\/ Visual:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/             .bar\n\/\/\/             .baz()\n\/\/\/ ```\n\/\/\/ Visual seems to be a tab indented from the indent of the whole expression.\n\/\/\/ Inherit:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/ .bar\n\/\/\/ .baz()\n\/\/\/ ```\n\/\/\/ Tabbed:\n\/\/\/ ```\n\/\/\/ let a = foo(aaa, bbb)\n\/\/\/     .bar\n\/\/\/     .baz()\n\/\/\/ ```\n\/\/\/ `chains_overflow_last` applies only to chains where the last item is a\n\/\/\/ method call. Usually, any line break in a chain sub-expression causes the\n\/\/\/ whole chain to be split with newlines at each `.`. With `chains_overflow_last`\n\/\/\/ true, then we allow the last method call to spill over multiple lines without\n\/\/\/ forcing the rest of the chain to be split.\n\n\nuse Indent;\nuse rewrite::{Rewrite, RewriteContext};\nuse utils::{wrap_str, first_line_width};\nuse expr::rewrite_call;\nuse config::BlockIndentStyle;\n\nuse syntax::{ast, ptr};\nuse syntax::codemap::{mk_sp, Span};\n\n\npub fn rewrite_chain(expr: &ast::Expr,\n                     context: &RewriteContext,\n                     width: usize,\n                     offset: Indent)\n                     -> Option<String> {\n    let total_span = expr.span;\n    let (parent, subexpr_list) = make_subexpr_list(expr);\n\n    \/\/ Parent is the first item in the chain, e.g., `foo` in `foo.bar.baz()`.\n    let parent_block_indent = chain_base_indent(context, offset);\n    let parent_context = &RewriteContext { block_indent: parent_block_indent, ..*context };\n    let parent_rewrite = try_opt!(parent.rewrite(parent_context, width, offset));\n\n    \/\/ Decide how to layout the rest of the chain. `extend` is true if we can\n    \/\/ put the first non-parent item on the same line as the parent.\n    let (indent, extend) = if !parent_rewrite.contains('\\n') && is_continuable(parent) ||\n                              parent_rewrite.len() <= context.config.tab_spaces {\n        \/\/ Try and put at least the first two items on the same line.\n        (chain_indent(context, offset + Indent::new(0, parent_rewrite.len())), true)\n    } else if is_block_expr(parent, &parent_rewrite) {\n        \/\/ The parent is a block, so align the rest of the chain with the closing\n        \/\/ brace.\n        (parent_block_indent, false)\n    } else if parent_rewrite.contains('\\n') {\n        (chain_indent(context, parent_block_indent.block_indent(context.config)), false)\n    } else {\n        (hacked_chain_indent(context, offset + Indent::new(0, parent_rewrite.len())), false)\n    };\n\n    let max_width = try_opt!((width + offset.width()).checked_sub(indent.width()));\n    let mut rewrites = try_opt!(subexpr_list.iter()\n                                            .rev()\n                                            .map(|e| {\n                                                rewrite_chain_subexpr(e,\n                                                                      total_span,\n                                                                      context,\n                                                                      max_width,\n                                                                      indent)\n                                            })\n                                            .collect::<Option<Vec<_>>>());\n\n    \/\/ Total of all items excluding the last.\n    let almost_total = rewrites[..rewrites.len() - 1]\n                           .iter()\n                           .fold(0, |a, b| a + first_line_width(b)) +\n                       parent_rewrite.len();\n    let total_width = almost_total + first_line_width(rewrites.last().unwrap());\n\n    let veto_single_line = if context.config.take_source_hints && subexpr_list.len() > 1 {\n        \/\/ Look at the source code.

Crate ruma_api contains core types used to define the requests and responses for each endpoint\n\/\/! in the various [Matrix](https:\/\/matrix.org) API specifications.\n\/\/! These types can be shared by client and server code for all Matrix APIs.\n\/\/!\n\/\/! When implementing a new Matrix API, each endpoint has a type that implements `Endpoint`, plus\n\/\/! the necessary associated types.\n\/\/! An implementation of `Endpoint` contains all the information about the HTTP method, the path and\n\/\/! input parameters for requests, and the structure of a successful response.\n\/\/! Such types can then be used by client code to make requests, and by server code to fulfill\n\/\/! those requests.\n\n#![deny(\n    missing_copy_implementations,\n    missing_debug_implementations,\n

It can be excessively inefficient to work directly with a `Reader` or\n\/\/! `Writer`. Every call to `read` or `write` on `TcpStream` results in a\n\/\/! system call, for example. This module provides structures that wrap\n\/\/! `Readers`, `Writers`, and `Streams` and buffer input and output to them.\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let reader = BufferedReader::new(tcp_stream);\n\/\/!\n\/\/! let mut buf: ~[u8] = vec::from_elem(100, 0u8);\n\/\/! match reader.read(buf.as_slice()) {\n\/\/!     Some(nread) => println!(\"Read {} bytes\", nread),\n\/\/!     None => println!(\"At the end of the stream!\")\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let writer = BufferedWriter::new(tcp_stream);\n\/\/!\n\/\/! writer.write(\"hello, world\".as_bytes());\n\/\/! writer.flush();\n\/\/! ```\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let stream = BufferedStream::new(tcp_stream);\n\/\/!\n\/\/! stream.write(\"hello, world\".as_bytes());\n\/\/! stream.flush();\n\/\/!\n\/\/! let mut buf = vec::from_elem(100, 0u8);\n\/\/! match stream.read(buf.as_slice()) {\n\/\/!     Some(nread) => println!(\"Read {} bytes\", nread),\n\/\/!

It can be excessively inefficient to work directly with a `Reader` or\n\/\/! `Writer`. Every call to `read` or `write` on `TcpStream` results in a\n\/\/! system call, for example. This module provides structures that wrap\n\/\/! `Readers`, `Writers`, and `Streams` and buffer input and output to them.\n\/\/!\n\/\/! # Examples\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let reader = BufferedReader::new(tcp_stream);\n\/\/!\n\/\/! let mut buf: ~[u8] = vec::from_elem(100, 0u8);\n\/\/! match reader.read(buf.as_slice()) {\n\/\/!     Some(nread) => println!(\"Read {} bytes\", nread),\n\/\/!     None => println!(\"At the end of the stream!\")\n\/\/! }\n\/\/! ```\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let writer = BufferedWriter::new(tcp_stream);\n\/\/!\n\/\/! writer.write(\"hello, world\".as_bytes());\n\/\/! writer.flush();\n\/\/! ```\n\/\/!\n\/\/! ```\n\/\/! let tcp_stream = TcpStream::connect(addr);\n\/\/! let stream = BufferedStream::new(tcp_stream);\n\/\/!\n\/\/! stream.write(\"hello, world\".as_bytes());\n\/\/! stream.flush();\n\/\/!\n\/\/! let mut buf = vec::from_elem(100, 0u8);\n\/\/! match stream.read(buf.as_slice()) {\n\/\/!     Some(nread) => println!(\"Read {} bytes\", nread),\n\/\/!     None => println!(\"At the end of the stream!\")\n\/\/! }\n\/\/! ```\n\/\/!\n\nuse prelude::*;\n\nuse num;\nuse vec;\nuse str;\nuse super::{Reader, Writer, Stream, Decorator};\n\n\/\/ libuv recommends 64k buffers to maximize throughput\n\/\/ https:\/\/groups.google.com\/forum\/#!topic\/libuv\/oQO1HJAIDdA\nstatic DEFAULT_CAPACITY: uint = 64 * 1024;\n\n\/\/\/ Wraps a Reader and buffers input from it\npub struct BufferedReader<R> {\n    priv inner: R,\n    priv buf: ~[u8],\n    priv pos: uint,\n    priv cap: uint\n}\n\nimpl<R: Reader> BufferedReader<R> {\n    \/\/\/ Creates a new `BufferedReader` with with the specified buffer capacity\n    pub fn with_capacity(cap: uint, inner: R) -> BufferedReader<R> {\n        BufferedReader {\n            inner: inner,\n            buf: vec::from_elem(cap, 0u8),\n            pos: 0,\n            cap: 0\n        }\n    }\n\n    \/\/\/ Creates a new `BufferedReader` with a default buffer capacity\n    pub fn new(inner: R) -> BufferedReader<R> {\n        BufferedReader::with_capacity(DEFAULT_CAPACITY, inner)\n    }\n\n    \/\/\/ Reads the next line of input, interpreted as a sequence of utf-8\n    \/\/\/ encoded unicode codepoints.

{"text":"<commit_before><commit_msg>Implement an ad-hoc case folding pass<commit_after>\/*! Special casing for the purpose of hyphenation\n\nImplemented here is a \"refolding\" pass which covers complementary case\nmappings (rarely) required for the correct hyphenation of uppercase or\nmixed-case words.\n\nPatterns maintained by the TeX project are not generated in strict accordance\nwith Unicode case folding; rather, they include multiple concrete sequences\nat the discretion of the pattern developer, under the assumption that words\nmay be lowercased with varying degrees of Unicode awareness.\n\nAlthough the approach works quite well when matching against `str`, two\ndiscrepancies remain:\n\n- Firstly, folding may shift character boundaries, invalidating the indices\nof opportunities found by our dictionaries, which are byte-based and have\nno notion of `char`. Thus, any opportunity found in a folded word must be\nmapped back to its correct position in the original, unfolded word.\n- Secondly, patterns may not account for all concrete sequences that occur\nwhen using `str::to_lowercase` as a loose folding pass.\n\nA zealous solution would be to adopt proper caseless matching, and pre-fold\nthe bundled patterns. Presently, however, we rely on an ad-hoc remedy based\non supplementary case mappings.\n\n\n# Supplementary case mappings\n\n| uppercase            | lowercase            | refold\n|----------------------|----------------------|----------------\n|'İ' \\u{130}, length 2 | \"i\\u{307}\", length 3 | \"i\", length 1\n\nThe Turkish `İ` in its recomposed form is – to the author's knowledge –\nthe only codepoint which changes size when lowercased without normalization\nor tailoring. It is thus necessary to fold it regardless of language or\ncontext, because the equivalence-preserving lowercase \"i\\u{307}\" not only\ndisrupts pattern matching – be it byte-based or char-based – but also\nshifts and invalidates any opportunity arising after it.\n*\/\n\nuse std::borrow::Cow;\nuse std::borrow::Cow::*;\n\n\n#[derive(Copy, Clone, Debug)]\npub struct Shift {\n    index : usize,\n    delta : isize\n}\n\n\/\/\/ The opportunity `i`, index-corrected for use in the original string.\npub fn realign(i : usize, shifts : &[Shift]) -> usize {\n    (i as isize - shift_at(i, shifts)) as usize\n}\n\n\/\/\/ The shift at index `i` in the refolded string.\nfn shift_at(i : usize, shifts : &[Shift]) -> isize {\n    shifts.iter().rev()\n        .find(|&&shift| i > shift.index)\n        .map_or(0, |&shift| shift.delta)\n}\n\nfn shifts(word : &str) -> Vec<Shift> {\n    word.match_indices(\"İ\")\n        .map(|(i, _)| (i, -1))\n        .scan(0, |delta, (i, d)| {\n            let index = i as isize + *delta;\n            *delta += d;\n            Some(Shift { index : index as usize, delta : *delta })\n        }).collect()\n}\n\n\n\/\/\/ Should the original string contain special-cased codepoints, refold it\n\/\/\/ for hyphenation and provide the induced index shifts.

{"text":"<commit_before>\/\/! Implementation of mio for Windows using IOCP\n\/\/!\n\/\/! This module uses I\/O Completion Ports (IOCP) on Windows to implement mio's\n\/\/! Unix epoll-like interface. Unfortunately these two I\/O models are\n\/\/! fundamentally incompatible:\n\/\/!\n\/\/! * IOCP is a completion-based model where work is submitted to the kernel and\n\/\/!   a program is notified later when the work finished.\n\/\/! * epoll is a readiness-based model where the kernel is queried as to what\n\/\/!   work can be done, and afterwards the work is done.\n\/\/!\n\/\/! As a result, this implementation for Windows is much less \"low level\" than\n\/\/! the Unix implementation of mio. This design decision was intentional,\n\/\/! however.\n\/\/!\n\/\/! ## What is IOCP?\n\/\/!\n\/\/! The [official docs][docs] have a comprehensive explanation of what IOCP is,\n\/\/! but at a high level it requires the following operations to be executed to\n\/\/! perform some I\/O:\n\/\/!\n\/\/! 1. A completion port is created\n\/\/! 2. An I\/O handle and a token is registered with this completion port\n\/\/! 3. Some I\/O is issued on the handle. This generally means that an API was\n\/\/!    invoked with a zeroed `OVERLAPPED` structure. The API will immediately\n\/\/!    return.\n\/\/! 4. After some time, the application queries the I\/O port for completed\n\/\/!    events. The port will returned a pointer to the `OVERLAPPED` along with\n\/\/!    the token presented at registration time.\n\/\/!\n\/\/! Many I\/O operations can be fired off before waiting on a port, and the port\n\/\/! will block execution of the calling thread until an I\/O event has completed\n\/\/! (or a timeout has elapsed).\n\/\/!\n\/\/! Currently all of these low-level operations are housed in a separate `miow`\n\/\/! crate to provide a 0-cost abstraction over IOCP. This crate uses that to\n\/\/! implement all fiddly bits so there's very few actual Windows API calls or\n\/\/! `unsafe` blocks as a result.\n\/\/!\n\/\/! [docs]: https:\/\/msdn.microsoft.com\/en-us\/library\/windows\/desktop\/aa365198%28v=vs.85%29.aspx\n\/\/!\n\/\/! ## Safety of IOCP\n\/\/!\n\/\/! Unfortunately for us, IOCP is pretty unsafe in terms of Rust lifetimes and\n\/\/! such. When an I\/O operation is submitted to the kernel, it involves handing\n\/\/! the kernel a few pointers like a buffer to read\/write, an `OVERLAPPED`\n\/\/! structure pointer, and perhaps some other buffers such as for socket\n\/\/! addresses. These pointers all have to remain valid **for the entire I\/O\n\/\/! operation's duration**.\n\/\/!\n\/\/! There's 0-cost way to define a safe lifetime for these pointers\/buffers over\n\/\/! the span of an I\/O operation, so we're forced to add a layer of abstraction\n\/\/! (not 0-cost) to make these APIs safe. Currently this implementation\n\/\/! basically just boxes everything up on the heap to give it a stable address\n\/\/! and then keys of that most of the time.\n\/\/!\n\/\/! ## From completion to readiness\n\/\/!\n\/\/! Translating a completion-based model to a readiness-based model is also no\n\/\/! easy task, and a significant portion of this implementation is managing this\n\/\/! translation. The basic idea behind this implementation is to issue I\/O\n\/\/! operations preemptively and then translate their completions to a \"I'm\n\/\/! ready\" event.\n\/\/!\n\/\/! For example, in the case of reading a `TcpSocket`, as soon as a socket is\n\/\/! connected (or registered after an accept) a read operation is executed.\n\/\/! While the read is in progress calls to `read` will return `WouldBlock`, and\n\/\/! once the read is completed we translate the completion notification into a\n\/\/! `readable` event. Once the internal buffer is drained (e.g. all data from it\n\/\/! has been read) a read operation is re-issued.\n\/\/!\n\/\/! Write operations are a little different from reads, and the current\n\/\/! implementation is to just schedule a write as soon as `write` is first\n\/\/! called. While that write operation is in progress all future calls to\n\/\/! `write` will return `WouldBlock`. Completion of the write then translates to\n\/\/! a `writable` event. Note that this will probably want to add some layer of\n\/\/! internal buffering in the future.\n\/\/!\n\/\/! ## Buffer Management\n\/\/!\n\/\/! As there's lots of I\/O operations in flight at any one point in time,\n\/\/! there's lots of live buffers that need to be juggled around (e.g. this\n\/\/! implementaiton's own internal buffers).\n\/\/!\n\/\/! Currently all buffers are created for the I\/O operation at hand and are then\n\/\/! discarded when it completes (this is listed as future work below).\n\/\/!\n\/\/! ## Callback Management\n\/\/!\n\/\/! When the main event loop receives a notification that an I\/O operation has\n\/\/! completed, some work needs to be done to translate that to a set of events\n\/\/! or perhaps some more I\/O needs to be scheduled. For example after a\n\/\/! `TcpStream` is connected it generates a writable event and also schedules a\n\/\/! read.\n\/\/!\n\/\/! To manage all this the `Selector` uses the `OVERLAPPED` pointer from the\n\/\/! completion status. The selector assumes that all `OVERLAPPED` pointers are\n\/\/! actually pointers to the interior of a `selector::Overlapped` which means\n\/\/! that right after the `OVERLAPPED` itself there's a function pointer. This\n\/\/! function pointer is given the completion status as well as another callback\n\/\/! to push events onto the selector.\n\/\/!\n\/\/! The callback for each I\/O operation doesn't have any environment, so it\n\/\/! relies on memory layout and unsafe casting to translate an `OVERLAPPED`\n\/\/! pointer (or in this case a `selector::Overlapped` pointer) to a type of\n\/\/! `FromRawArc<T>` (see module docs the for why this type exists).\n\/\/!\n\/\/! ## Thread Safety\n\/\/!\n\/\/! Currently all of the I\/O primitives make liberal use of `Arc` and `Mutex`\n\/\/! as an implementation detail. The main reason for this is to ensure that the\n\/\/! types are `Send` and `Sync`, but the implementations have not been stressed\n\/\/! in multithreaded situations yet. As a result, there are bound to be\n\/\/! functional surprises in using these concurrently.\n\/\/!\n\/\/! ## Future Work\n\/\/!\n\/\/! First up, let's take a look at unimplemented portions of this module:\n\/\/!\n\/\/! * The `PollOpt::level()` option is currently entirely unimplemented.\n\/\/! * Each `EventLoop` currently owns its completion port, but this prevents an\n\/\/!   I\/O handle from being added to multiple event loops (something that can be\n\/\/!   done on Unix). Additionally, it hinders event loops moving across threads.\n\/\/!   This should be solved by likely having a global `Selector` which all\n\/\/!   others then communicate with.\n\/\/! * Although Unix sockets don't exist on Windows, there are named pipes and\n\/\/!   those should likely be bound here in a similar fashion to `TcpStream`.\n\/\/!\n\/\/! Next up, there are a few performance improvements and optimizations that can\n\/\/! still be implemented\n\/\/!\n\/\/! * Buffer management right now is pretty bad, they're all just allocated\n\/\/!   right before an I\/O operation and discarded right after. There should at\n\/\/!   least be some form of buffering buffers.\n\/\/! * No calls to `write` are internally buffered before being scheduled, which\n\/\/!   means that writing performance is abysmal compared to Unix. There should\n\/\/!   be some level of buffering of writes probably.\n\nuse std::io;\nuse std::os::windows::prelude::*;\n\nuse kernel32;\nuse winapi;\n\nmod awakener;\n#[macro_use]\nmod selector;\nmod tcp;\nmod udp;\nmod from_raw_arc;\nmod buffer_pool;\nmod iovec;\n\npub use self::awakener::Awakener;\npub use self::selector::{Events, Selector, Overlapped, Binding};\npub use self::tcp::{TcpStream, TcpListener};\npub use self::udp::UdpSocket;\npub use self::iovec::IoVec;\n\n#[derive(Copy, Clone)]\nenum Family {\n    V4, V6,\n}\n\nfn wouldblock() -> io::Error {\n    io::Error::new(io::ErrorKind::WouldBlock, \"operation would block\")\n}\n\nunsafe fn cancel(socket: &AsRawSocket,\n                 overlapped: &Overlapped) -> io::Result<()> {\n    let handle = socket.as_raw_socket() as winapi::HANDLE;\n    let ret = kernel32::CancelIoEx(handle, overlapped.as_mut_ptr());\n    if ret == 0 {\n        Err(io::Error::last_os_error())\n    } else {\n        Ok(())\n    }\n}\n<commit_msg>Several typo fixes for sys\/windows\/mod.rs<commit_after>\/\/!
