Expand description
Creates a combinator that runs the five given futures until one or more completes, returning a tuple containing the result of the finished future(s) and the still pending future(s).
§Example
use cros_async::{SelectResult, select5, block_on};
use futures::future::pending;
use futures::pin_mut;
let first = async {4};
let second = async {let () = pending().await;};
let third = async {5};
let fourth = async {let () = pending().await;};
let fifth = async {6};
pin_mut!(first);
pin_mut!(second);
pin_mut!(third);
pin_mut!(fourth);
pin_mut!(fifth);
match block_on(select5(first, second, third, fourth, fifth)) {
(SelectResult::Finished(4), SelectResult::Pending(_second),
SelectResult::Finished(5), SelectResult::Pending(_fourth),
SelectResult::Finished(6)) => (),
_ => panic!("Select didn't return the futures"),
};
