Function channel 

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

🔬This is a nightly-only experimental API. (oneshot_channel #143674)

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

Examples

#![feature(oneshot_channel)]
use std::sync::oneshot;
use std::thread;

let (sender, receiver) = oneshot::channel();

// Spawn off an expensive computation.
thread::spawn(move || {
    sender.send(expensive_computation()).unwrap();
    // `sender` is consumed by `send`, so we cannot use it anymore.
});

do_other_work();

// Let's see what that answer was...
println!("{:?}", receiver.recv().unwrap());
// `receiver` is consumed by `recv`, so we cannot use it anymore.
