ReuniteError

Error indicating a SplitSink<S> and SplitStream<S> were not two halves of a Stream + Split, and thus could not be reunited.

Select

Stream for the select() function.

SelectAll

An unbounded set of streams

SelectNextSome

Future for the select_next_some method.

Skip

Stream for the skip method.

SkipWhile

Stream for the skip_while method.

SplitSink

A Sink part of the split pair

SplitStream

A Stream part of the split pair

StreamFuture

Future for the into_future method.

Take

Stream for the take method.

TakeWhile

Stream for the take_while method.

Then

Stream for the then method.

TryBufferUnordered

Stream for the try_buffer_unordered method.

TryCollect

Future for the try_collect method.

Future for the try_next method.

TrySkipWhile

Stream for the try_skip_while method.

Unfold

Stream for the unfold function.

Zip

Stream for the zip method.

Traits

FusedStream

A Stream or TryStream which tracks whether or not the underlying stream should no longer be polled.

Stream

A stream of values produced asynchronously.

StreamExt

An extension trait for Streams that provides a variety of convenient combinator functions.

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

Functions

empty

Creates a stream which contains no elements.

iter

Converts an Iterator into a Stream which is always ready to yield the next value.

once

Creates a stream of a single element.

pending

Creates a stream which never returns any elements.

poll_fn

Creates a new stream wrapping a function returning Poll<Option<T>>.

repeat

Create a stream which produces the same item repeatedly.

select

This function will attempt to pull items from both streams. Each stream will be polled in a round-robin fashion, and whenever a stream is ready to yield an item that item is yielded.

select_all

Convert a list of streams into a Stream of results from the streams.

unfold

Creates a Stream from a seed and a closure returning a Future.

Type Definitions

BoxStream

An owned dynamically typed Stream for use in cases where you can't statically type your result or need to add some indirection.
