[][src]Struct futures::future::Select

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

Future for the select combinator, waiting for one of two futures to complete.

This is created by the Future::select method.
