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 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)));
