          # mypy thinks transport is a BaseTransport, not a Transport.

docs: Configure write buffer limits.
  
          The high-water limit is defined by ``self.write_limit``.
  
          The low-water limit currently defaults to ``self.write_limit // 4`` in
          :meth:`~asyncio.WriteTransport.set_write_buffer_limits`, which should
          be all right for reasonable use cases of this library.
  
          This is the earliest point where we can get hold of the transport,
          which means it's the best point for configuring it.
