[+]

type Item = M::Result

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

type Error = MailboxError

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

fn poll(&mut self) -> Poll<Self::Item, Self::Error>

[−]

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>

[−]

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,

[−]

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,

[−]

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

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

[−]

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     B: IntoFuture,     F: FnOnce(Result<Self::Item, Self::Error>) -> B,

[−]

Chain on a computation for when a future finished, passing the result of the future to the provided closure f.

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

[−]

Execute another future if this one resolves with an error.

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

[−]

Waits for either one of two futures to complete.

fn select2<B>(self, other: B) -> Select2<Self, <B as IntoFuture>::Future> where     B: IntoFuture,

[−]

Waits for either one of two differently-typed futures to complete.
