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: main.rs
    path of file: ./repos/code/ch6/ch6-memscan-3/src
    
    the code of the file until where you have to start completion: static GLOBAL: i32 = 1000;             // <1>

fn noop() -> *const i32 {
    let noop_local = 12345;    
    
fn main() {
    let local_str = "a";               // <4>
    let local_int = 123;               // <4>
    let boxed_str = Box::new('b');     // <4>
    let boxed_int = Box::new(789);     // <4>
    let fn_int = noop();               // <4>

    println!("GLOBAL:    {:p}", &GLOBAL as *const i32);
    println!("local_str: {:p}", local_str as *const str);
    println!("local_int: {:p}", &local_int as *const i32);
    println!("boxed_int: {:p}", Box::into_raw(boxed_int));
    println!("boxed_str: {:p}", Box::into_raw(boxed_str));
    println!("fn_int:    {:p}", fn_int);
}
