Notable traits for Join<Fut1, Fut2>
impl<Fut1, Fut2> Future for Join<Fut1, Fut2> where
    Fut1: Future,
    Fut2: Future,     type Output = (<Fut1 as Future>::Output, <Fut2 as Future>::Output);
 where
    Fut1: Future,
    Fut2: Future, 

Joins the result of two futures, waiting for them both to complete.

This function will return a new future which awaits both futures to complete. The returned future will finish with a tuple of both results.

Note that this function consumes the passed futures and returns a wrapped version of it.

Examples

use futures::future;

let a = async { 1 };
let b = async { 2 };
let pair = future::join(a, b);

assert_eq!(pair.await, (1, 2));
