Returns a new instance of MatchSpec.

Parameters:

  • req_args (Fixnum) (defaults to: nil) —

    Number of required args, nil for any.

  • opt_args (Fixnum) (defaults to: nil) —

    Number of optional args, nil for any.

  • has_rest_args (Boolean) (defaults to: nil) —

    Number of required keyward args, nil for any.

  • key_args (Fixnum) (defaults to: nil) —

    Number of optional keyward args, nil for any.

  • has_keyrest_args (Boolean) (defaults to: nil) —

    Whether a **opts is defined, nil for any. If has_keyrest_args is true, then any number of keyreq or key args will satisfy this match for name named opts.

  • has_block (Boolean) (defaults to: nil) —
