Overview

This module is part of a private API. This module may only be used in the Homebrew/brew repository. Third parties should avoid using this module if possible, as it may be removed or changed without warning.

Note:

The compiler is fragile, and must be updated if the filename changes, if methods are added or removed, or if a method's arity changes.

This module provides methods to define specialized attributes. Method stubs are generated by the Tapioca::Compilers::Attrables compiler.
