code: def iter(self, *, encoding=None, decoder=None):
          
          return _IterHelper(self,
                             is_active=lambda ch: ch.is_active,
                             encoding=encoding,
                             decoder=decoder)
docs: Same as get method but its native coroutine.
  
          Usage example:
  
          >>> async for msg in ch.iter():
          ...     print(msg)
