poll

import std::future::poll; · source

Poll<T>#

type enum Poll<T> {
    Ready(T);
    Pending;
}

implement enum Poll<T> {
    is_ready(&this) -> boolean;
    is_pending(&this) -> boolean;
    ![sink]
    into_ready(&this) -> T;
}

The result of one poll call. Pending means "not yet — I have arranged to be woken"; Ready(v) means the value is available and the future is done. into_ready unwraps a Poll you know is ready and panics otherwise, which is what a test driving a future by hand wants.
