pub struct CloneCounterObserver(/* private fields */);
Expand description

An observer that can be cloned without modifying the clone counter, but can be used to inspect its state and awaited

Zero-indexed, but each [CloneCounter] retrieved with CloneCounterObserver::counter increments the count by 1.

Awaiting a CloneCounterObserver will be pending until all associated [CloneCounter]s have been dropped, and will resolve to () when the count is 0.

Implementations§

§

impl CloneCounterObserver

pub fn new() -> CloneCounterObserver

returns a new observer with a zero count. use CloneCounterObserver::counter to

pub fn current(&self) -> usize

returns the current counter value

pub fn counter(&self) -> CloneCounter

creates a new CloneCounter from this observer, incrementing the count
