Struct futures::future::OrElse [] [src]

#[must_use = "futures do nothing unless polled"]
pub struct OrElse<A, B, F> where
    A: Future,
    B: IntoFuture
{ /* fields omitted */ }

Future for the or_else combinator, chaining a computation onto the end of a future which fails with an error.

This is created by the Future::or_else method.
