Struct SharedDataLocked

source

pub struct SharedDataLocked<'a, T> { /* private fields */ }

Expand description

Created by SharedData::shared_data_locked.

As long as this object isn’t dropped, the shared data is held in a mutex guard and the shared data is tagged as locked. Access to the shared data is provided through Deref and DerefMut. The trick is to use Self::release_mutex to release the mutex, but still keep the shared data locked. This means every other thread trying to access the shared data in this time will need to wait until this lock is freed.

If this object is dropped without calling Self::release_mutex, the lock will be dropped immediately.
