Struct SinkErrInto

pub struct SinkErrInto<S, E>
where
    S: Sink,
{ /* private fields */ }

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

This is created by the Sink::err_into method.

Implementations

impl<S, E> SinkErrInto<S, E>

where S: Sink,

pub fn get_ref(&self) -> &S

Get a shared reference to the inner sink.

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

Get a mutable reference to the inner sink.

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.

Trait Implementations

impl<S, E> Clone for SinkErrInto<S, E>

where S: Clone + Sink, E: Clone, <S as Sink>::SinkError: Clone,

fn clone(&self) -> SinkErrInto<S, E>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, E> Debug for SinkErrInto<S, E>

where S: Debug + Sink, E: Debug, <S as Sink>::SinkError: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<S, E> Sink for SinkErrInto<S, E>

where S: Sink, <S as Sink>::SinkError: Into<E>,

type SinkItem = <S as Sink>::SinkItem

The type of value that the sink accepts.

type SinkError = E

The type of value produced by the sink when an error occurs.

fn poll_ready( &mut self, cx: &mut Context<'_>, ) -> Result<Async<()>, <SinkErrInto<S, E> as Sink>::SinkError>

Attempts to prepare the Sink to receive a value.

fn start_send( &mut self, item: <SinkErrInto<S, E> as Sink>::SinkItem, ) -> Result<(), <SinkErrInto<S, E> as Sink>::SinkError>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Ok(Async::Ready(())).

fn poll_flush( &mut self, cx: &mut Context<'_>, ) -> Result<Async<()>, <SinkErrInto<S, E> as Sink>::SinkError>

Flush any remaining output from this sink.

fn poll_close( &mut self, cx: &mut Context<'_>, ) -> Result<Async<()>, <SinkErrInto<S, E> as Sink>::SinkError>

Flush any remaining output and close this sink, if necessary.

impl<S, E> Stream for SinkErrInto<S, E>

where S: Sink + Stream,

type Item = <S as Stream>::Item

Values yielded by the stream.

type Error = <S as Stream>::Error

Errors yielded by the stream.

fn poll_next( &mut self, cx: &mut Context<'_>, ) -> Result<Async<Option<<S as Stream>::Item>>, <S as Stream>::Error>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.
