code: def set_info_future(self, jid, node, fut):
          
          self._info_pending[jid, node] = fut
docs: Override the cache entry (if one exists) for :meth:`query_info` of the
          `jid` and `node` combination with the given :class:`asyncio.Future`
          fut.
  
          The future must receive a :class:`dict` compatible to the output of
          :meth:`.xso.InfoQuery.to_dict`.
  
          As usual, the cache can be bypassed and cleared by passing
          `require_fresh` to :meth:`query_info`.

             Module :mod:`aioxmpp.entitycaps`
               :xep:`0115` implementation which uses this method to prime the
               cache with information derived from Entity Capability
               announcements.
  
          .. note::
  
             If a future is set to exception state, it will still remain and make
             all queries for that target fail with that exception, until a query
             uses `require_fresh`.
