Module futures

Expand description

Abstractions for asynchronous programming.

Modules§

join: Polls multiple futures simultaneously, returning a tuple of all results once complete.
pending: A macro which yields to the event loop once.
pin_mut: Pins a value on the stack.
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. If multiple futures are ready, one will be pseudo-randomly selected at runtime. Futures directly passed to select! must be Unpin and implement FusedFuture.
select_biased: 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.
stream_select: 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.
try_join: Polls multiple futures simultaneously, resolving to a Result containing either a tuple of the successful outputs or an error.

AsyncBufRead: Read bytes asynchronously.
AsyncBufReadExt: An extension trait which adds utility methods to AsyncBufRead types.
AsyncRead: Read bytes asynchronously.
AsyncReadExt: An extension trait which adds utility methods to AsyncRead types.
AsyncSeek: Seek bytes asynchronously.
AsyncSeekExt: An extension trait which adds utility methods to AsyncSeek types.
AsyncWrite: Write bytes asynchronously.
AsyncWriteExt: An extension trait which adds utility methods to AsyncWrite types.
Future: A future represents an asynchronous computation obtained by use of async.
FutureExt: An extension trait for Futures that provides a variety of convenient adapters.
Sink: A Sink is a value into which other values can be sent, asynchronously.
SinkExt: An extension trait for Sinks that provides a variety of convenient combinator functions.
Stream: A stream of values produced asynchronously.
StreamExt: An extension trait for Streams that provides a variety of convenient combinator functions.
TryFuture: A convenience for futures that return Result values that includes a variety of adapters tailored to such futures.
TryFutureExt: Adapters specific to Result-returning futures
TryStream: A convenience for streams that return Result values that includes a variety of adapters tailored to such futures.
TryStreamExt: Adapters specific to Result-returning streams
