[Piotr Zegar via cfe-commits]

https://github.com/PiotrZSL requested changes to this pull request.

Overall, may require some small work to make sure that code is straightforward and simple.
As for functionality part, still has some gaps or redundant parts, but that is not a blocker.

Please try to refactor your changes to be simpler, like function names to actually say what they doing.
