Function casper_node::utils::wait_for_arc_drop

pub async fn wait_for_arc_drop<T>(
    arc: Arc<T>, 
    attempts: usize, 
    retry_delay: Duration
) -> bool

Wait until all strong references for a particular arc have been dropped.

Downgrades and immediately drops the Arc, keeping only a weak reference. The reference will then be polled attempts times, unless it has a strong reference count of 0.

Returns whether or not arc has zero strong references left.

Note

Using this function is usually a potential architectural issue and it should be used very sparingly. Consider introducing a different access pattern for the value under Arc.
