[−][src]Struct futures_util::future::Fuse
#[must_use = "futures do nothing unless polled"]pub struct Fuse<Fut: Future> { /* fields omitted */ }
A future which "fuses" a future once it's been resolved.
Normally futures can behave unpredictable once they're used after a future
has been resolved, but Fuse is always defined to return Async::Pending
from poll after it has resolved successfully or returned an error.
This is created by the Future::fuse method.
