Struct futures_util::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
sourceimpl<Si1, Si2> Fanout<Si1, Si2>
impl<Si1, Si2> Fanout<Si1, Si2>
sourcepub fn get_pin_mut(self: Pin<&mut Self>) -> (Pin<&mut Si1>, Pin<&mut Si2>)
pub fn get_pin_mut(self: Pin<&mut Self>) -> (Pin<&mut Si1>, Pin<&mut Si2>)
Get a pinned mutable reference to the inner sinks.
sourcepub fn into_inner(self) -> (Si1, Si2)
pub fn into_inner(self) -> (Si1, Si2)
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.
