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.
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.
try_unfold	Creates a TryStream from a seed and a closure returning a TryFuture.
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.
