A trait implemented by default for all Futures which extends the standard functionality.

Provided methods

pub fn discard(self) -> Discard<Self>[src]

Map a Future to have Item=() and Error=(). This is useful when a future is being used to drive a computation but the actual results aren't interesting (such as when used with Handle::spawn()).

pub fn boxify(self) -> BoxFuture<Self::Item, Self::Error> where
    Self: 'static + Send, [src]

Create a Sendable boxed version of this Future.

pub fn boxify_nonsend(self) -> BoxFutureNonSend<Self::Item, Self::Error> where
    Self: 'static, [src]

Create a non-Sendable boxed version of this Future.

pub fn left_future<B>(self) -> Either<Self, B>[src]

Shorthand for returning future::Either::A

pub fn right_future<A>(self) -> Either<A, Self>[src]

Shorthand for returning future::Either::B

pub fn inspect_err<F>(self, f: F) -> InspectErr<Self, F> where
    F: FnOnce(&Self::Error),
    Self: Sized, [src]

Similar to future::Future::inspect, but runs the function on error

pub fn inspect_result<F>(self, f: F) -> InspectResult<Self, F> where
    F: FnOnce(Result<&Self::Item, &Self::Error>),
    Self: Sized, [src]

Similar to future::Future::inspect, but runs the function on both output or error of the Future treating it as a regular Result
