Struct actix::fut::Then

#[must_use = "futures do nothing unless polled"]
pub struct Then<A, B, F: 'static> where
    A: ActorFuture,
    B: IntoActorFuture<Actor = A::Actor>,  { /* fields omitted */ }

Future for the then combinator, chaining computations on the end of another future regardless of its outcome.

This is created by the Future::then method.

Trait Implementations

impl<A, B, F> ActorFuture for Then<A, B, F> where
    A: ActorFuture,
    B: IntoActorFuture<Actor = A::Actor>,
    F: FnOnce(A::Output, &mut A::Actor, &mut <A::Actor as Actor>::Context) -> B, 

type Output = B::Output

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

type Actor = A::Actor

The actor within which this future runs

fn poll(
    self: Pin<&mut Self>,
    act: &mut A::Actor,
    ctx: &mut <A::Actor as Actor>::Context,
    task: &mut Context
) -> Poll<B::Output>

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.

impl<A: Debug, B: Debug, F: Debug + 'static> Debug for Then<A, B, F> where
    A: ActorFuture,
    B: IntoActorFuture<Actor = A::Actor>,
    B::Future: Debug, 

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

Formats the value using the given formatter.

impl<'pin, A, B, F: 'static> Unpin for Then<A, B, F> where
    A: ActorFuture,
    B: IntoActorFuture<Actor = A::Actor>,
    __Then<'pin, A, B, F>: Unpin,
