Struct futures::sink::SinkErrInto

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

Sink for the sink_err_into method.

Methods

impl<Si, E, Item> SinkErrInto<Si, Item, E> where
    Si: Sink<Item>,
    <Si as Sink<Item>>::Error: Into<E>, 

Important traits for &'_ mut F

impl<'_, F> Future for &'_ mut F where
    F: Unpin + Future + ?Sized,  type Output = <F as Future>::Output;

pub fn get_ref(&self) -> &Si

Get a shared reference to the inner sink.

Important traits for &'_ mut F

impl<'_, F> Future for &'_ mut F where
    F: Unpin + Future + ?Sized,  type Output = <F as Future>::Output;

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

Get a mutable reference to the inner sink.

Important traits for Pin<P>

impl<P> Future for Pin<P> where
    P: Unpin + DerefMut,
    <P as Deref>::Target: Future,  type Output = <<P as Deref>::Target as Future>::Output;

pub fn get_pin_mut(self: Pin<&mut SinkErrInto<Si, Item, E>>) -> Pin<&mut Si>

Get a pinned mutable reference to the inner sink.

pub fn into_inner(self) -> Si

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<Si, Item, E> Sink<Item> for SinkErrInto<Si, Item, E> where
    Si: Sink<Item>,
    <Si as Sink<Item>>::Error: Into<E>, 

type Error = E

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

fn poll_ready(
    self: Pin<&mut SinkErrInto<Si, Item, E>>,
    cx: &mut Context
) -> Poll<Result<(), <SinkErrInto<Si, Item, E> as Sink<Item>>::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(
    self: Pin<&mut SinkErrInto<Si, Item, E>>,
    item: Item
) -> Result<(), <SinkErrInto<Si, Item, E> as Sink<Item>>::Error>

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 Poll::Ready(Ok(())).

fn poll_flush(
    self: Pin<&mut SinkErrInto<Si, Item, E>>,
    cx: &mut Context
) -> Poll<Result<(), <SinkErrInto<Si, Item, E> as Sink<Item>>::Error>>

Flush any remaining output from this sink.

fn poll_close(
    self: Pin<&mut SinkErrInto<Si, Item, E>>,
    cx: &mut Context
) -> Poll<Result<(), <SinkErrInto<Si, Item, E> as Sink<Item>>::Error>>

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

impl<S, Item, E> Stream for SinkErrInto<S, Item, E> where
    S: Sink<Item> + Stream,
    <S as Sink<Item>>::Error: Into<E>, 

type Item = <S as Stream>::Item

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut SinkErrInto<S, Item, E>>,
    cx: &mut Context
) -> Poll<Option<<S as Stream>::Item>>

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.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<S, Item, E> FusedStream for SinkErrInto<S, Item, E> where
    S: Sink<Item> + FusedStream,
    <S as Sink<Item>>::Error: Into<E>, 

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<Si, Item, E> Debug for SinkErrInto<Si, Item, E> where
    E: Debug,
    Item: Debug,
    Si: Debug + Sink<Item>,
    <Si as Sink<Item>>::Error: Debug, 

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

Formats the value using the given formatter.
