Defined in:

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.

The callable response bodies are a new Rack 3.x feature, and would not work with older Rack versions. They must not respond to each because "If it responds to each, you must call each and not call". This is why it inherits from BodyWrapper directly and not from EnumerableBodyWrapper
