std::sync::mpsc::channel - Rust
Description: API documentation for the Rust `channel` fn in crate `std`.
Keywords: rust, rustlang, rust-lang, channel

# Function std::sync::mpsc::channel 1.0.0 [−] [src]

    pub fn channel<T>() -> (Sender<T>, Receiver<T>)

Creates a new asynchronous channel, returning the sender/receiver halves.

All data sent on the sender will become available on the receiver, and no send will block the calling thread (this channel has an "infinite buffer").

# Examples

    use std::sync::mpsc::channel;
    use std::thread;

    // tx is the sending half (tx for transmission), and rx is the receiving
    // half (rx for receiving).
    let (tx, rx) = channel();

    // Spawn off an expensive computation
    thread::spawn(move|| {
        tx.send(expensive_computation()).unwrap();
    });

    // Do some useful work for awhile

    // Let's see what that answer was
    println!("{:?}", rx.recv().unwrap());Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
