Function futures::channel::oneshot::channel

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

Creates a new one-shot channel for sending values across asynchronous tasks.

This function is similar to Rust's channel constructor found in the standard library. Two halves are returned, the first of which is a Sender handle, used to signal the end of a computation and provide its value. The second half is a Receiver which implements the Future trait, resolving to the value that was given to the Sender handle.

Each half can be separately owned and sent across tasks.

Examples

use futures::channel::oneshot;
use futures::future::FutureExt;
use std::thread;

let (sender, receiver) = oneshot::channel::<i32>();

thread::spawn(|| {
    let future = receiver.map(|i| {
        println!("got: {:?}", i);
    });
    // ...
});

sender.send(3).unwrap();
