Module guard 

The guard module manages read access to shared memory, utilizing RAII (Resource Acquisition Is Initialization) principles to control access lifecycle.

ReadGuard is the primary structure in this module. On creation, ReadGuard provides a reference to an entity in shared memory. This reference can be safely used until the grace_duration set in the write method of the synchronizer module expires.

ReadGuard relinquishes memory access rights automatically when it goes out of scope and gets dropped, thus avoiding potential memory corruption due to lingering references. Therefore, users must ensure all ReadGuard instances are dropped before grace_duration expires.

The synchronizer module utilizes this guard module to manage memory safety, allowing users to focus on their application logic.
