Expand description
Asynchronous streams.
This module contains:
- The
Streamtrait, for objects that can asynchronously produce a sequence of values. - The
StreamExtandTryStreamExttrait, which provides adapters for chaining and composing streams. - Top-level stream constructors like
iterwhich creates a stream from an iterator.
Modules
An unbounded set of futures.
An unbounded set of streams
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.
Indicator that the Abortable task was aborted.
Stream for the buffer_unordered
method.
Stream for the catch_unwind method.
Stream for the filter_map method.
Future for the for_each_concurrent
method.
An unbounded queue of futures.
A set of futures which may complete in any order.
Stream for the inspect_err method.
Stream for the inspect_ok method.
Reader for the into_async_read method.
Stream for the into_stream method.
Future for the Peekable::next_if method.
Future for the 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 reunited.
An unbounded set of streams
Future for the select_next_some
method.
Stream for the select_with_strategy() function. See function docs for details.
Stream for the skip_while method.
A Sink part of the split pair
A Stream part of the split pair
Future for the into_future method.
Stream for the take_until method.
Stream for the take_while method.
Stream for the
try_buffer_unordered method.
Stream for the try_buffered method.
Stream for the try_chunks method.
Error indicating, that while chunk was collected inner stream produced an error.
Future for the try_collect method.
Future for the try_concat method.
Stream for the try_filter
method.
Stream for the try_filter_map
method.
Stream for the try_flatten method.
Future for the try_for_each method.
Future for the
try_for_each_concurrent
method.
Stream for the try_skip_while
method.
Stream for the try_take_while
method.
Stream for the try_unfold function.
Enums
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 Streams 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 streams
Functions
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.
BoxStream, but without the Send requirement.
