  "\n    Wrapper around the `lsm_cursor` object.\n\n    Functions :py:meth:`seek`, :py:meth:`first`, and :py:meth:`last` are\n    *seek* functions. Whether or not :py:meth:`next` and :py:meth:`previous`\n    may be called successfully depends on the most recent seek function called\n    on the cursor. Specifically,\n\n    * At least one seek function must have been called on the cursor.\n    * To call ``next()``, the most recent call to a seek function must have\n      been either ``first()`` or a call to ``seek()`` specifying ``SEEK_GE``.\n    * To call ``previous()``, the most recent call to a seek function must have\n      been either ``last()`` or a call to ``seek()`` specifying ``SEEK_LE``.\n\n    Otherwise, if the above conditions are not met when ``next()`` or\n    ``previous()`` is called, ``LSM_MISUSE`` is returned and the cursor\n    position remains unchanged.\n\n    For more information, see:\n\n    http://www.sqlite.org/src4/doc/trunk/www/lsmusr.wiki#reading_from_a_database\n    ", /*tp_doc*/
