#[must_use = "futures do nothing unless polled"]
pub struct SinkErrInto<Si, E> where
    Si: Sink
{ /* fields omitted */ }

A sink combinator to change the error type of a sink.

This is created by the Sink::err_into method.

Methods

impl<Si, E> SinkErrInto<Si, E> where
    Si: Sink,
    <Si as Sink>::SinkError: Into<E>, 
[src]

Important traits for &'a mut I

Get a shared reference to the inner sink.

Important traits for &'a mut I

Get a mutable reference to the inner sink.

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.
