pub struct InFlightGuard {
keys: Arc<InFlightKeys>,
key: String,
}Expand description
RAII marker returned by InFlightKeys::begin. Decrements its key’s
count on drop – on task completion, on early return (e.g. admission
saturated), and on panic unwind alike – removing the key only once the
count reaches zero, so one of two concurrent fills for the same key ending
can never un-mark the other’s still-running fill.

Casts
self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read moreSource§impl<T> BorrowMut<T> for Twhere
