Struct futures_util::sink::SinkErrInto

pub struct SinkErrInto<Si: Sink<Item>, Item, E> { /* private fields */ }

Sink for the sink_err_into method.

Implementations

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

pub fn get_ref(&self) -> &Si

Acquires a reference to the underlying sink or stream that this combinator is pulling from.

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

Acquires a mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut Si>

Acquires a pinned mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn into_inner(self) -> Si

Consumes this combinator, returning the underlying sink or stream.

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

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

Formats the value using the given formatter.

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

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

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

type Error = E

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

fn poll_ready(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Item) -> Result<(), Self::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 Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::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::Error: Into<E>,

type Item = <S as Stream>::Item

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Self::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<'__pin, Si: Sink<Item>, Item, E> Unpin for SinkErrInto<Si, Item, E>where
    __Origin<'__pin, Si, Item, E>: Unpin,
