Struct MutexGuard 

pub struct MutexGuard<'a, T: ?Sized> { /* private fields */ }

RAII guard that unlocks a Mutex<T> when dropped.

Deref / DerefMut expose the protected value. MutexGuard is !Send: the locking thread must release the lock. Sending a guard to another thread would cause that thread to issue ove_mutex_unlock with no matching ove_mutex_lock, which is backend-defined UB. The _no_send field carries a GuardNoSend PhantomData to propagate !Send at compile time (the same trick lock_api / parking_lot use on stable Rust).

Sync is reinstated for T: Sync — a &MutexGuard<T> is the same as a &T, which is Send if T: Sync. Matches std and parking_lot.
