Module futures_util::stream
source · [−]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
filter_map method.Stream for the
flat_map_unordered 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.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.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.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.Stream for the
try_flatten_unordered 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 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.
