Struct actix::fut::Then [−][src]
#[must_use = "futures do nothing unless polled"]pub struct Then<A, B, F> 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.
