Module futures_util::stream

Streams

This module contains a number of functions for working with Streams, including the StreamExt trait which adds methods to Stream types.

Modules

futures_unordered

An unbounded set of futures.

Structs

Collect	Future for the collect method.
Concat	Future for the concat method.
Empty	Stream for the empty function.
Filter	Stream for the filter method.
FilterMap	Stream for the filter_map method.

Once	A stream which emits single element and then EOF.
Peekable	A Stream that implements a peek method.
PollFn	Stream for the poll_fn function.
Repeat	Stream for the repeat function.
ReuniteError	Error indicating a SplitSink<S> and SplitStream<S> were not two halves of a Stream + Split, and thus could not be reunited.

Then	Stream for the then method.
Unfold	Stream for the unfold function.
Zip	Stream for the zip method.

Traits

StreamExt

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

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 single element
poll_fn	Creates a new stream wrapping around a function returning Poll.
repeat	Create a stream which produces the same item repeatedly.
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.
