Struct futures::prelude::sink::Fanout

source ·
pub struct Fanout<Si1, Si2> { /* private fields */ }
Expand description

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.

Implementations§

Get a shared reference to the inner sinks.

Get a mutable reference to the inner sinks.

Get a pinned mutable reference to the inner sinks.

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.
