     19 /// ==================

     21 /// This implementation hooks in through the XRay logging implementation
     22 /// framework. The Basic Mode implementation will keep appending to a file as
     23 /// soon as the thread-local buffers are full. It keeps minimal in-memory state
     24 /// and does the minimum filtering required to keep log files smaller.
