Module futures_util::sink

Sinks

This module contains a number of functions for working with Sinks, including the SinkExt trait which adds methods to Sink types.

Structs

Buffer	Sink for the Sink::buffer combinator, which buffers up to some fixed number of values when the underlying sink is unable to accept them.
Close	Future for the close combinator, which polls the sink until all data has been closed.
Drain	A sink that will discard all items given to it.
Fanout	Sink that clones incoming items and forwards them to two sinks at the same time.
Flush	Future for the flush combinator, which polls the sink until all data has been flushed.
Send	Future for the Sink::send combinator, which sends a value to a sink and then waits until the sink has fully flushed.
SendAll	Future for the Sink::send_all combinator, which sends a stream of values to a sink and then waits until the sink has fully flushed those values.
SinkErrInto	A sink combinator to change the error type of a sink.
SinkMapErr	Sink for the Sink::sink_map_err combinator.
With	Sink for the Sink::with combinator, chaining a computation to run prior to pushing a value into the underlying sink.
WithFlatMap	Sink for the Sink::with_flat_map combinator, chaining a computation that returns an iterator to run prior to pushing a value into the underlying sink.

Enums

DrainError

The error type for the Drain sink.

Traits

SinkExt

An extension trait for Sinks that provides a variety of convenient combinator functions.

Functions

drain

Create a sink that will just discard all items given to it.
