===========================
Rule ``ordered_interfaces``
===========================

Orders the interfaces in an ``implements`` or ``interface extends`` clause.

Configuration
-------------

``order``
~~~~~~~~~

How the interfaces should be ordered.

Allowed values: ``'alpha'`` and ``'length'``

Default value: ``'alpha'``

``direction``
~~~~~~~~~~~~~

Which direction the interfaces should be ordered.

Allowed values: ``'ascend'`` and ``'descend'``

Default value: ``'ascend'``

``case_sensitive``
~~~~~~~~~~~~~~~~~~

Whether the sorting should be case sensitive.

Allowed types: ``bool``

Default value: ``false``
