`ADD CONTENT HERE TO DESCRIBE THE PURPOSE OF THE PULL REQUEST`
# Formatting
- [ ] I am following the formatting style of the existing codebase.
_a clang-format configuration file is available in the root of g3log_
# Testing
- [ ] This new/modified code was covered by unit tests.
- [ ] (insight) Was all tests written using TDD (Test Driven Development) style?
- [ ] The CI (Windows, Linux, OSX) are working without issues.
- [ ] Was new functionality documented?
- [ ] The testing steps 1 - 2 below were followed
_step 1_
