pub struct GuardImpl<M, H, P> where
    M: ArcMutexMapLike,
    H: Hooks<M::V>,
    P: Borrow<LockableMapImpl<M, H>>,  { /* private fields */ }

Expand description

A RAII implementation of a scoped lock for locks from a LockableHashMap or LockableLruCache. When this instance is dropped (falls out of scope), the lock will be unlocked.
