[−][src]Crate futures_util

Combinators and utilities for working with Futures, Streams, Sinks, and the AsyncRead and AsyncWrite traits.

Modules

async_await	Await
future	Futures
io	IO
lock	Futures-powered synchronization primitives.
sink	Sinks
stream	Streams
task	Task notification
try_future	Futures
try_stream	Streams

join	Polls multiple futures simultaneously, returning a tuple of all results once complete.
pending	A macro which yields to the event loop once.
poll	A macro which returns the result of polling a future once within the current `async` context.
ready	Extracts the successful type of a `Poll<T>`.
select	Polls multiple futures and streams simultaneously, executing the branch for the future that finishes first. Futures passed to `select!` must be `Unpin` and implement `FusedFuture`. Futures and streams which are not already fused can be fused using the `.fuse()` method. Note, though, that fusing a future or stream directly in the call to `select!` will not be enough to prevent it from being polled after completion if the `select!` call is in a loop, so when `select!`ing in a loop, users should take care to `fuse()` outside of the loop.
try_join	Polls multiple futures simultaneously, resolving to a `Result` containing either a tuple of the successful outputs or an error.
try_poll	Extracts `Poll<T>` from `Poll<Result<T, E>>`.
try_ready	Extracts the successful type of a `Poll<Result<T, E>>`.
