class GraphQL::Schema::Directive::Flagged

In this case, the server hides types and fields entirely, unless the current context has certain ‘:flags` present.
This is similar to {Directive::Feature}, except it’s prescribed by the server, not the client.

    # This is type class of some kind, `include` will put this module
    # in between the type class itself and its super class, so `super` will work fine
    target.include(VisibleByFlag)
  elsif !target.is_a?(VisibleByFlag)
    # This is an instance of a base class. `include` won't put this in front of the
    # base class implementation, so we need to `.prepend`.
    # `#visible?` could probably be moved to a module and then this could use `include` instead.
