module RSpec::Core::MetadataFilter

Contains metadata filtering logic. This has been extracted from the metadata classes because it operates ON a metadata hash but does not manage any of the state in the hash. We’re moving towards having metadata be a raw hash (not a custom subclass), so externalizing this filtering logic helps us move in that direction.
