Struct futures_util::try_future::OrElse [−][src]
#[must_use = "futures do nothing unless polled"]pub struct OrElse<Fut1, Fut2, F> { /* 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.
