Struct len_caching_lock::mutex::LenCachingMutex
source · [−]pub struct LenCachingMutex<T: ?Sized> { /* private fields */ }Expand description
Can be used in place of a Mutex where reading T’s len() without
needing to lock, is advantageous.
When the Guard is released, T’s len() will be cached.
The cached len() may be at most 1 lock behind current state.

Load the cached value that was returned from your T’s len()
subsequent to the most recent lock being released.
