Struct futures::sink::Fanout

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.
