Struct futures::sink::Fanout[][src]

pub struct Fanout<A: Sink, B: Sink> { /* fields omitted */ }

Sink that clones incoming items and forwards them to two sinks at the same time.

Backpressure from any downstream sink propagates up, which means that this sink can only process items as fast as its slowest downstream sink.

Methods

impl<A: Sink, B: Sink> Fanout<A, B>
[src]

Consumes this combinator, returning the underlying sinks.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
