Module sink

Asynchronous sinks.

This module contains:

• The Sink trait, which allows you to asynchronously write data.

• The SinkExt trait, which provides adapters for chaining and composing sinks.

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.

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

Traits

Sink

A Sink is a value into which other values can be sent, asynchronously.

SinkExt

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