Asynchronous values.
Asynchronous I/O.
Futures-powered synchronization primitives.
This module contains the
Never type.Asynchronous sinks.
Asynchronous streams.
Tools for working with tasks.
Macros
Polls multiple futures simultaneously, returning a tuple
of all results once complete.
A macro which yields to the event loop once.
Pins a value on the stack.
A macro which returns the result of polling a future once within the
current
async context.Extracts the successful type of a
Poll<T>.Polls multiple futures and streams simultaneously, executing the branch
for the future that finishes first. If multiple futures are ready,
one will be pseudo-randomly selected at runtime. Futures directly
passed to
select! must be Unpin and implement FusedFuture.Polls multiple futures and streams simultaneously, executing the branch
for the future that finishes first. Unlike
select!, if multiple futures are ready,
one will be selected in order of declaration. Futures directly
passed to select_biased! must be Unpin and implement FusedFuture.Combines several streams, all producing the same
Item type, into one stream.
This is similar to select_all but does not require the streams to all be the same type.
It also keeps the streams inline, and does not require Box<dyn Stream>s to be allocated.
Streams passed to this macro must be Unpin.
