How to use the pyfuse3.readdir_reply function in pyfuse3

async def readdir(self, id_, off, token):
        log.debug('started with %d, %d', id_, off)
        if off == 0:

        # them.
        with self.db.query("SELECT name_id, name, inode FROM contents_v "
                           'WHERE parent_inode=? AND name_id > ? ORDER BY name_id',
                           (id_, off-3)) as res:
