pub struct Send<S: Sink> { /* fields omitted */ }

[−] Expand description

Future for the Sink::send combinator, which sends a value to a sink and then waits until the sink has fully flushed.

pub fn get_ref(&self) -> &S[−]

Get a shared reference to the inner sink.

pub fn get_mut(&mut self) -> &mut S[−]

[+] Show hidden undocumented items

type Item = S

The type of value that this future will resolved with if it is successful.

type Error = S::SinkError

The type of error that this future will resolve with if it fails in a normal fashion.

fn poll(&mut self) -> Poll<S, S::SinkError>[−]

Query this future to see if its value has become available, registering interest if it is not.

fn wait(self) -> Result<Self::Item, Self::Error> where
    Self: Sized, [−]

Block the current thread until this future is resolved.

fn map<F, U>(self, f: F) -> Map<Self, F> where
    F: FnOnce(Self::Item) -> U,
    Self: Sized, [−]

Map this future's result to a different type, returning a new future of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F> where
    F: FnOnce(Self::Error) -> E,
    Self: Sized, [−]

Map this future's error to a different error, returning a new future.

fn from_err<E: From<Self::Error>>(self) -> FromErr<Self, E> where
    Self: Sized, [−]

Map this future's error to any error implementing From for this future's Error, returning a new future.

fn then<F, B>(self, f: F) -> Then<Self, B, F> where
    F: FnOnce(Result<Self::Item, Self::Error>) -> B,
    B: IntoFuture,
    Self: Sized, [−]

fn and_then<F, B>(self, f: F) -> AndThen<Self, B, F> where
    F: FnOnce(Self::Item) -> B,
    B: IntoFuture<Error = Self::Error>,
    Self: Sized, [−]

Execute another future after this one has resolved successfully.

fn or_else<F, B>(self, f: F) -> OrElse<Self, B, F> where
    F: FnOnce(Self::Error) -> B,
    B: IntoFuture<Item = Self::Item>,
    Self: Sized, [−]

Execute another future if this one resolves with an error.

fn select<B>(self, other: B) -> Select<Self, B::Future> where
    B: IntoFuture<Item = Self::Item, Error = Self::Error>,
    Self: Sized, [−]
