Function `join3`

fn join3<Fut1, Fut2, Fut3>(future1: Fut1, future2: Fut2, future3: Fut3) -> Join3<Fut1, Fut2, Fut3>
where
    Fut1: Future,
    Fut2: Future,
    Fut3: Future

Same as join, but with more futures.

Examples

# futures::executor::block_on(async {
use futures::future;

let a = async { 1 };
let b = async { 2 };
let c = async { 3 };
let tuple = future::join3(a, b, c);

assert_eq!(tuple.await, (1, 2, 3));
# });
