Struct holochain::prelude::dependencies::kitsune_p2p_types::dependencies::futures::prelude::sink::Fanout
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
impl<Si1, Si2> Fanout<Si1, Si2>
impl<Si1, Si2> Fanout<Si1, Si2>
pub fn get_pin_mut(
self: Pin<&mut Fanout<Si1, Si2>>
) -> (Pin<&mut Si1>, Pin<&mut Si2>)
pub fn get_pin_mut(
self: Pin<&mut Fanout<Si1, Si2>>
) -> (Pin<&mut Si1>, Pin<&mut Si2>)
Get a pinned mutable reference to the inner sinks.
pub 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.
