Active Support Descendants Tracker
This module provides an internal implementation to track descendants which is faster than iterating through ObjectSpace
.
However Ruby 3.1 provide a fast native +Class#subclasses+ method, so if you know your code won’t be executed on older rubies, including ActiveSupport::DescendantsTracker
does not provide any benefit.
