Module future

Structs§

CatchUnwind: Future for the FutureExt::catch_unwind() method.
Fuse: Future for the fuse method.
Or: Future for the or() function and the FutureExt::or() method.
Pending: Creates a future which never resolves, representing a computation that never finishes.
PollFn: Future for the poll_fn() function.
PollOnce: Future for the poll_once() function.
Race: Future for the race() function and the FutureExt::race() method.
Ready: A future that is immediately ready with a value.
TryZip: Future for the try_zip() function.
YieldNow: Future for the yield_now() function.
Zip: Future for the zip() function.

Future: A future represents an asynchronous computation, commonly obtained by use of async.
FutureExt: Extension trait for Future.

block_on: Blocks the current thread on a future.
fuse: Fuse a future such that poll will never again be called once it has 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.
pending: Creates a future which never resolves, representing a computation that never finishes.
poll_fn: Creates a future from a function returning Poll.
poll_once: Polls a future just once and returns an Option with the result.
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.
ready: Creates a future that is immediately ready with a value.
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 once.
zip: Joins two futures, waiting for both to complete.
