pub struct Guard<'a, L: Lock<I> + ?Sized, I: LockInfo = WriteLock> { /* private fields */ }

Expand description

Allows mutual exclusion primitives that implement the Lock trait to automatically unlock when a guard goes out of scope. It also provides a safe and convenient way to access the data protected by the lock.
