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

BufferUnordered	Stream for the buffer_unordered method.
Buffered	Stream for the buffered method.
CatchUnwind	Stream for the catch_unwind method.
Chain	Stream for the chain method.
Chunks	Stream for the chunks method.
Collect	Future for the collect method.
Concat	Future for the concat method.
Empty	Stream for the empty function.
Enumerate	Stream for the enumerate method.
Filter	Stream for the filter method.
FilterMap	Stream for the filter_map method.
Flatten	Stream for the flatten method.
Fold	Future for the fold method.
ForEach	Future for the for_each method.
ForEachConcurrent	Future for the for_each_concurrent method.
Forward	Future for the forward method.
Fuse	Stream for the fuse method.
FuturesOrdered	An unbounded queue of futures.
FuturesUnordered	A set of futures which may complete in any order.
Inspect	Stream for the inspect method.
Iter	Stream for the iter function.
Map	Stream for the map method.
Next	Future for the next method.
Once	A stream which emits single element and then EOF.
Peekable	A Stream that implements a peek method.
Pending	Stream for the pending() function.
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.
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.
Unfold	Stream for the unfold function.
Zip	Stream for the zip method.

Traits

FusedStream	A stream 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.

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.
LocalBoxStream	BoxStream, but without the Send requirement.
