Constructor Details

#initialize(mod = nil, method:, version:, name: nil, supported: nil, native: nil, location: nil, refineable: mod, core_ext: :patch, singleton: nil) ⇒ Patch

Create a new patch for module/class (mod) with the specified uniq name

‘core_ext` defines the strategy for core extensions:

- :patch — extend class directly
- :prepend — extend class by prepending a module (e.g., when needs `super`)
