:relfileprefix: ../../
:mrdocs:

This class provides a proctor that, unless the `release` method has been previously invoked, will remove and destroy all the elements from a `FixedQueue` object supplied at construction (putting that ring‐buffer into a valid empty state) upon the proctor's destruction. Note that this guard is used to provide exception safety when pushing an element into a `FixedQueue`.
