[][src]Struct futures::future::Flatten

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

Future for the flatten combinator, flattening a future-of-a-future to get just the result of the final future.

This is created by the Future::flatten method.
