Struct With 

pub struct With<Si, Item, U, Fut, F, E> { /* private fields */ }

Sink for the with method.

Implementations

impl<Si, Item, U, Fut, F, E> With<Si, Item, U, Fut, F, E>

where Si: Sink<Item>, F: FnMut(U) -> Fut, Fut: Future<Output = Result<Item, E>>, E: From<Si::Error>,

pub fn get_ref(&self) -> &Si

Acquires a reference to the underlying sink.

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

Acquires a mutable reference to the underlying sink.

Note that care must be taken to avoid tampering with the state of the sink 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.

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

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, U, Fut, F, E> Clone for With<Si, Item, U, Fut, F, E>

where Si: Clone, F: Clone, Fut: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Si, Item, U, Fut, F, E> Debug for With<Si, Item, U, Fut, F, E>

where Si: Debug, Fut: Debug,

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

Formats the value using the given formatter.

impl<Si, Item, U, Fut, F, E> Sink<U> for With<Si, Item, U, Fut, F, E>

where Si: Sink<Item>, F: FnMut(U) -> Fut, Fut: Future<Output = Result<Item, E>>, E: From<Si::Error>,

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: U) -> 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, U, Fut, F, E> Stream for With<S, Item, U, Fut, F, E>

where S: Stream + Sink<Item>, F: FnMut(U) -> Fut, Fut: Future<Output = Result<Item, E>>, E: From<S::Error>,

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<Si: Unpin, Item, U, Fut: Unpin, F, E> Unpin for With<Si, Item, U, Fut, F, E>
