Discussion

The output handler is your opportunity to encapsulate or encode a signle application message. You should write any output using nw_framer_write_output(_:_:_:), nw_framer_write_output_data(_:_:), or nw_framer_write_output_no_copy(_:_:) before returning from the output handler. If you do not write a message, the application message will be discarded.
