Module futures_util::stream
source · Expand description
Asynchronous streams.
This module contains:
- The
Stream
trait, for objects that can asynchronously produce a sequence of values. - The
StreamExt
andTryStreamExt
trait, which provides adapters for chaining and composing streams. - Top-level stream constructors like
iter
which creates a stream from an iterator.
Modules
An unbounded set of futures.

Structs
A handle to an
Abortable
task.A registration handle for an
Abortable
task.
Values of this type can be acquired from AbortHandle::new
and are used
in calls to Abortable::new
.A future/stream which can be remotely short-circuited using an
AbortHandle

method.Future for the
Peekable::next_if

Peekable::next_if_eq
method.A stream which emits single element and then EOF.
Future for the
Peekable::peek
method.Future for the
Peekable::peek_mut
method.A
Stream
that implements a peek
method.Stream for the poll_immediate function.
Stream for the
ready_chunks
method.An stream that repeats elements of type
A
endlessly by
applying the provided closure F: FnMut() -> A
.Error indicating a
SplitSink<S>
and SplitStream<S>
were not two halves
of a Stream + Split
, and thus could not be reunite

Type to tell
SelectWithStrategy
which stream to poll next.Traits
A stream which tracks whether or not the underlying stream
should no longer be polled.
A stream of values produced asynchronously.
An extension trait for
Stream
s that provides a variety of convenient
combinator functions.A convenience for streams that return
Result
values that includes
a variety of adapters tailored to such futures.Adapters specific to
Result
-returning streamsFunctions
Creates a new
Abortable
stream and an AbortHandle
which can be used to stop it.Creates a stream which contains no elements.
Converts an
Iterator
into a Stream
which is always ready
to yield the next value.Creates a stream of a single element.
Creates a stream which never returns any elements.
Creates a new stream wrapping a function returning
Poll<Option<T>>
.Creates a new stream that always immediately returns Poll::Ready when awaiting it.
Create a stream which produces the same item repeatedly.
Creates a new stream that repeats elements of type
A
endlessly by
applying the provided closure, the repeater, F: FnMut() -> A
.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.
Convert a list of streams into a
Stream
of results from the streams.This function will attempt to pull items from both streams. You provide a
closure to tell
SelectWithStrategy
which stream to poll. The closure can
store state on SelectWithStrategy
to which it will receive a &mut
on every
invocation. This allows basing the strategy on prior choices.Creates a
TryStream
from a seed and a closure returning a TryFuture
.Creates a
Stream
from a seed and a closure returning a Future
.Type Definitions
An owned dynamically typed
Stream
for use in cases where you can’t
statically type your result or need to add some indirection.Stream for the
flatten_unordered
method.BoxStream
, but without the Send
requirement.
