type MappedRwLockWriteGuard<'a, T> = MappedRwLockWriteGuard<'a, RawRwLock, T>;

An RAII write lock guard returned by RwLockWriteGuard::map, which can point to a subfield of the protected data.

The main difference between MappedRwLockWriteGuard and RwLockWriteGuard is that the former doesn't support temporarily unlocking and re-locking, since that could introduce soundness issues if the locked object is modified by another thread.
