Streams

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

Structs

Chain	Stream for the `chain` 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.
Forward	Future for the `forward` method.
Fuse	Stream for the `fuse` method.
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.
Select	Stream for the `select()` function.
SelectNextSome	Future for the `select_next_some` method.
Skip	Stream for the `skip` method.
SkipWhile	Stream for the `skip_while` method.
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.

An extension trait for Streams that provides a variety of convenient combinator 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.
unfold	Creates a `Stream` from a seed and a closure returning a `Future`.
