Trait Implementations

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

type Item = S::Item

The type of item this stream will yield on success.

type Error = S::Error

The type of error this stream may generate.

type Actor = A

The actor within which this stream runs.

fn poll(
    &mut self,
    _: &mut Self::Actor,
    _: &mut <Self::Actor as Actor>::Context
) -> Poll<Option<Self::Item>, Self::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,
    Self: Sized, 

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,
    Self: Sized, 

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>,
    Self: Sized, 

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>,
    Self: Sized, 

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::Error>,
    Self: Sized, 

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: Sized,
    Self::Error: Clone, 

Add timeout to stream.

fn finish(self) -> StreamFinish<Self> where
    Self: Sized, 

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