Detailed Description

RAII guard that temporarily removes a stream from a LogStream and re-inserts it on scope exit.

This class provides exception-safe temporary removal of output streams from LogStream objects. Use this when you need to temporarily suppress logging to a specific stream (e.g., cout) during operations that may throw exceptions.

Example usage:

LogSinkGuard guard(getGlobalLogInfo(), cout); // Removes cout, will re-insert on scope exit
some_operation_that_may_throw();
// cout is automatically re-inserted when guard goes out of scope
