@abc.abstractmethod<EOL><INDENT>def can_lookup_trust_circles(self):<DEDENT>
return<EOL>
Tests if this user can look up trusts for agents.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known these methods will
        result in a ``PermissionDenied``. This is intended as a hint to
        an application that may opt not to offer create operations to
        users outside the circle.

        :return: ``false`` if trust methods are not authorized, ``true`` otherwise
        :rtype: ``boolean``
