Struct geng::prelude::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>

pub fn get_ref(&self) -> (&Si1, &Si2)

Get a shared reference to the inner sinks.

pub fn get_mut(&mut self) -> (&mut Si1, &mut Si2)

Get a mutable reference to the inner sinks.

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)

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.
