Implementations§

Source§

impl<S, E> SinkErrInto<S, E>
where S: Sink,

Source

pub fn get_ref(&self) -> &S

Get a shared reference to the inner sink.

Source

pub fn get_mut(&mut self) -> &mut S

Source

pub fn into_inner(self) -> S

Consumes this combinator, returning the underlying sink.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
