So giving up on Visual Studio, C++ Builder, QtCreator, NVidia NSight productivity, and fast builds via UWP/COM tooling is compatibility with existing code/libraries?
If you find Visual Studio and CLion to be your desired work environments, both of them have support for Rust code via extensions. No it won't be as perfect as what you're used to, but it will be more than sufficient for most people.
I've also used QtCreator, and hated it because for me it was a resource hog, you had to do things its way, and the Qt APIs were horribly designed.
