You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: poll.rs
    path of file: ./repos/phaser/phaser/vendor/mio/src
    
    the code of the file until where you have to start completion: use crate::{event, sys, Events, Interest, Token};
use log::trace;
#[cfg(unix)]
use std::os::unix::io::{AsRawFd, RawFd};
use std::time::Duration;
use std::{fmt, io};

/// Polls for readiness events on all registered values.
///
/// `Poll` allows a program to monitor a large number of [`event::Source`]s,
/// waiting until one or more become "ready" for some class of operations; e.g.
/// reading and writing. An event sou
    
/// # fn main() -> Result<(), Box<dyn Error>> {
/// use mio::{Poll, Interest, Token};
/// use mio::net::TcpStream;
/// use std::net::SocketAddr;
/// use std::time::Duration;
/// use std::thread;
///
/// let address: SocketAddr = "127.0.0.1:0".parse()?;
/// let listener = net::TcpListener::bind(address)?;
/// let mut sock = TcpStream::connect(listener.local_addr()?)?;
///
/// thread::sleep(Duration::from_secs(1));
///
/// let poll = Poll::new()?;
///
/// // The connect is not guaranteed to have started until it is registered at
/// // this point
/// poll.registry().register(&mut sock, Token(0), Interest::READABLE | Interest::WRITABLE)?;
/// #     Ok(())
/// # }
