impl<T, E, A> ActorFuture for FutureResult<T, E, A> where     A: Actor,

[+]

type Item = T

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

type Error = E

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

type Actor = A

The actor within which this future runs

fn poll(     &mut self,     _: &mut Self::Actor,     _: &mut <Self::Actor as Actor>::Context ) -> Poll<T, E>

fn map<F, U>(self, f: F) -> Map<Self, F> where     F: FnOnce(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> 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, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> E,     Self: Sized,

[−]

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

fn drop_err(self) -> DropErr<Self> where     Self: Sized,

[−]

Drop this future's 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>, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B,     B: IntoActorFuture<Actor = Self::Actor>,     Self: Sized,

[−]

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

fn and_then<F, B>(self, f: F) -> AndThen<Self, B, F> where     F: FnOnce(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B,     B: IntoActorFuture<Error = Self::Error, Actor = Self::Actor>,     Self: Sized,

[−]

Execute another future after this one has resolved successfully.

fn timeout(self, timeout: Duration, err: Self::Error) -> Timeout<Self> where     Self: Sized,

[−]

Add timeout to futures chain.

impl<T, E, A> From<Result<T, E>> for FutureResult<T, E, A>

[+]

fn from(r: Result<T, E>) -> Self

[−]

Performs the conversion.
