Trait Implementations

impl<S, A> ActorStream for StreamWrap<S, A> where     A: Actor,     S: Stream,

[+]

type Item = <S as Stream>::Item

The type of item this stream will yield on success.

type Error = <S as Stream>::Error

The type of error this stream may generate.

type Actor = A

The actor within which this stream runs.

fn poll(     &mut self,     &mut <StreamWrap<S, A> as ActorStream>::Actor,     &mut <<StreamWrap<S, A> as ActorStream>::Actor as Actor>::Context ) -> Result<Async<Option<<StreamWrap<S, A> as ActorStream>::Item>>, <StreamWrap<S, A> as ActorStream>::Error>

fn map<U, F>(self, f: F) -> StreamMap<Self, F> where     F: FnMut(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> U,

[−]

Converts a stream of type T to a stream of type U.

fn map_err<E, F>(self, f: F) -> StreamMapErr<Self, F> where     F: FnMut(Self::Error, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> E,

[−]

Converts a stream of error type T to a stream of error type E.

fn then<F, U>(self, f: F) -> StreamThen<Self, F, U> where     F: FnMut(Result<Self::Item, Self::Error>, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> U,     U: IntoActorFuture<Actor = Self::Actor>,

[−]

Chain on a computation for when a value is ready, passing the resulting item to the provided closure f.

fn and_then<F, U>(self, f: F) -> StreamAndThen<Self, F, U> where     F: FnMut(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> U,     U: IntoActorFuture<Error = Self::Error, Actor = Self::Actor>,

[−]

Chain on a computation for when a value is ready, passing the successful results to the provided closure f.

fn fold<F, T, Fut>(self, init: T, f: F) -> StreamFold<Self, F, Fut, T> where     F: FnMut(T, Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> Fut,     Fut: IntoActorFuture<Actor = Self::Actor, Item = T>,     Self::Error: From<<Fut as IntoActorFuture>::Error>,

[−]

Execute an accumulating computation over a stream, collecting all the values into one final result.

fn timeout(self, timeout: Duration, err: Self::Error) -> StreamTimeout<Self> where     Self::Error: Clone,

[−]

Add timeout to stream.

fn finish(self) -> StreamFinish<Self>

[−]

Converts a stream to a future that resolves when stream finishes.
