Crate futures_util

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

Modules

async_await	Await
compat	Futures 0.1 / 0.3 shims
future	Futures
io	IO
lock	Futures-powered synchronization primitives.
sink	Sinks
stream	Streams
task	Task notification
try_future	Futures
try_stream	Streams

Macros

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 simultaneously, executing the branch for the future that finishes first.
spawn	Spawns a task onto the context's executor that polls the given future with output () to completion.
spawn_with_handle	Spawns a task onto the context's executor that polls the given future to completion and returns a future that resolves to the spawned future's output.
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>>.
