#formula_cache_paths(formula) ⇒ Array<Pathname>

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

Returns the cached <formula>--<version> and <formula>_bottle_manifest--<version> downloads for a formula. Globbing these per formula rescans the entire cache each time, which is quadratic for brew cleanup, so index the cache by name prefix once instead.

Parameters:
