//
// This class is multi-threaded, with some users calling |GetRuleIterator| off
// of the UI thread.
//
// Interacting with this class generally requires holding |GetLock|, and
// modifying rules while iterating over them is not permitted. Notably, due to
// complexity around ensuring the lock is held while iterating,
// |GetRuleIterator| should only be called while the lock is not held, as the
// Iterator itself will hold the lock until it's destroyed.
