Struct actix::fut::StreamFold

#[must_use = "streams do nothing unless polled"]pub struct StreamFold<S, F, Fut, T> where
    Fut: IntoActorFuture,  { /* fields omitted */ }

A future used to collect all the results of a stream into one generic type.

This future is returned by the ActorStream::fold method.

Trait Implementations

impl<S, F, Fut, T> ActorFuture for StreamFold<S, F, Fut, T> where
    S: ActorStream + Unpin,
    F: FnMut(T, S::Item, &mut S::Actor, &mut <S::Actor as Actor>::Context) -> Fut,
    Fut: IntoActorFuture<Output = T, Actor = S::Actor>,
    Fut::Future: ActorFuture + Unpin, 

type Output = T

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

type Actor = S::Actor

The actor within which this future runs

fn poll(
    self: Pin<&mut Self>,
    act: &mut S::Actor,
    ctx: &mut <S::Actor as Actor>::Context,
    task: &mut Context<'_>
) -> Poll<T>

fn map<F, U>(self, f: F) -> Map<Self, F> where
    F: FnOnce(Self::Output, &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 then<F, B>(self, f: F) -> Then<Self, B, F> where
    F: FnOnce(Self::Output, &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 timeout(self, timeout: Duration) -> Timeout<Self> where
    Self: Sized, 

Add timeout to futures chain.

    Fut: IntoActorFuture,
    Fut::Future: Debug, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
