Interesting that you won't replace Qt with Rust, because I'm considering doing it. The reasons:

- Qt core (QList, QMap) can be replaced with Rust std lib

- I don't use QML and Javascript (because Javascript errors don't show up at compile time)

- The only thing missing from Rust is QWidgets, but I'm sure there will be something to replace it

I wouldn't like to use a Rust port of Qt just to get QWidgets for Rust, because it would also mean shipping huge Qt core libraries with my Windows application. I don't need them so I don't want to do that.
