Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Once we hit the TT segment limit, we use this class to hold our place in the tree so that we can still get accurate names and times on the segments we’ve already created. The placeholder segment keeps a depth counter that’s incremented on each segment entry, and decremented on exit, until it reaches zero, when we throw the placeholder away. There should only ever be zero or one placeholder segment at a time.
