Struct ProgressingUntilStalled

Source

struct ProgressingUntilStalled {
    finished: Poll<()>,
    waker: Option<Waker>,
}

Expand description

State used for an in-progress call to progress_until_stalled

If present in Data, an (async) call to progress_until_stalled is in progress.

The future from progress_until_stalled, ProgressUntilStalledFuture is a normal-ish future. It can be polled in the normal way. When it is polled, it looks here, in finished, to see if it’s Ready.

The future is made ready, and woken (via waker), by bespoke code in the task executor loop.

When ProgressUntilStalledFuture (maybe completes and) is dropped, its Drop impl is used to remove this from Data.progressing_until_stalled.

Fields§

§finished: Poll<()>

Have we, in fact, stalled?

Made Ready by special code in the executor loop

§waker: Option<Waker>

Waker

Signalled by special code in the executor loop
