          This can only be used for assigning your own name flair or link flair
          on your own submissions. For assigning other's flairs using moderator
          access, see :meth:`~praw.__init__.ModFlairMixin.set_flair`.
  
          :param item: A string, Subreddit object (for user flair), or
              Submission object (for link flair). If ``item`` is a string it
              will be treated as the name of a Subreddit.
          :param flair_template_id: The id for the desired flair template. Use
              the :meth:`~praw.objects.Subreddit.get_flair_choices` and
              :meth:`~praw.objects.Submission.get_flair_choices` methods to find
              the ids for the available user and link flair choices.
          :param flair_text: A string containing the custom flair text.
              Used on subreddits that allow it.
