Struct actix::fut::AndThen [−][src]
#[must_use = "futures do nothing unless polled"]pub struct AndThen<A, B, F> where
A: ActorFuture,
B: IntoActorFuture<Actor = A::Actor>, { /* fields omitted */ }
Future for the and_then combinator, chaining a computation onto the end of
another future which completes successfully.
This is created by the Future::and_then method.
