Struct futures::sink::SinkFromErr [−][src]
#[must_use = "futures do nothing unless polled"]pub struct SinkFromErr<S, E> { /* fields omitted */ }
A sink combinator to change the error type of a sink.
This is created by the Sink::from_err
method.
Methods

[src]
impl<S, E> SinkFromErr<S, E>
pub fn get_ref(&self) -> &S
[src]
pub fn get_ref(&self) -> &S
Get a shared reference to the inner sink.
pub fn get_mut(&mut self) -> &mut S
[src]
pub fn get_mut(&mut self) -> &mut S
