Function futures_util::future::try_join3

pub fn try_join3<Fut1, Fut2, Fut3>(
    future1: Fut1,
    future2: Fut2,
    future3: Fut3
) -> TryJoin3<Fut1, Fut2, Fut3> 
where
    Fut1: TryFuture,
    Fut2: TryFuture<Error = Fut1::Error>,
    Fut3: TryFuture<Error = Fut1::Error>,

Same as try_join, but with more futures.

Examples

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 tuple = future::try_join3(a, b, c);

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