Sink for the with method.

Implementations

source

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

source

pub fn get_ref(&self) -> &Si

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

source

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.

source

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut Si>ⓘNotable traits for Pin`impl Future for Pinwhere P: DerefMut, ::Target: Future, type Output = <::Target as Future>::Output;`

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.

source

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.
