Function `try_join4`

fn try_join4<Fut1, Fut2, Fut3, Fut4>(future1: Fut1, future2: Fut2, future3: Fut3, future4: Fut4) -> TryJoin4<Fut1, Fut2, Fut3, Fut4>
where
    Fut1: TryFuture,
    Fut2: TryFuture<Error = <Fut1 as >::Error>,
    Fut3: TryFuture<Error = <Fut1 as >::Error>,
    Fut4: TryFuture<Error = <Fut1 as >::Error>

Same as try_join, but with more futures.

Examples

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

let a = future::ready(Ok::<i32, i32>(1));
let b = future::ready(Ok::<i32, i32>(2));
let c = future::ready(Ok::<i32, i32>(3));
let d = future::ready(Ok::<i32, i32>(4));
let tuple = future::try_join4(a, b, c, d);

assert_eq!(tuple.await, Ok((1, 2, 3, 4)));
# });
