Struct futures_util::future::SelectOk

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

Future for the select_ok combinator, waiting for one of any of a list of futures to successfully complete. Unlike select_all, this future ignores all but the last error, if there are any.

This is created by the select_ok function.
