18 /// ==================
19 ///
20 /// This implementation hooks in through the XRay logging implementation
21 /// framework. The Basic Mode implementation will keep appending to a file as
22 /// soon as the thread-local buffers are full. It keeps minimal in-memory state
23 /// and does the minimum filtering required to keep log files smaller.
