completed. This method can be used to turn any Future into a
FusedFuture. or Returns the result of the future that completes first, preferring future1 if both are ready. poll_fn Creates a future from a function returning Poll poll_once Polls a future just once and returns an Option race Returns the result of the future that completes first, with no preference if both are ready. race_with_seed Race two futures but with a predefined random seed. timeout If the future completes before the duration has elapsed, then the completed value is returned.
Otherwise, an error is returned and the future is canceled. try_zip Joins two fallible futures, waiting for both to complete or one of them to error. yield_now Wakes the current task and returns Poll::Pending zip Joins two futures, waiting for both to complete.
