}

Trait for types which are a placeholder of a value that may become available at some later point in time.

This is similar to futures::Future trait, except it works with Actor

Associated Types

type Item

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

type Error

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

type Actor: Actor

The actor within which this future runs

Required Methods

fn poll(
    &mut self,
    srv: &mut Self::Actor,
    ctx: &mut <Self::Actor as Actor>::Context
) -> Poll<Self::Item, Self::Error>

Provided Methods

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 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.
