OnFileRotationCallback is an alias for a user-supplied callback function that is invoked after the file observer attempts to rotate its log file. The callback takes two arguments: (1) an integer status value where 0 indicates a new log file was successfully created and a non-zero value indicates an error occurred during rotation, and (2) a string that provides the name of the rotated log file if the rotation was successful. E.g.: ` void onLogFileRotation(int rotationStatus, const bsl::string& rotatedLogFileName); `
