> Maybe one day we get Live++ or Visual Studio debugging experience for Rust
I don't know what Live++ is but the Rust debugging experience is already better than C++. In VSCode I can just click "Debug Test" next to a test and it magically all works. It's never that slick in C++, even in Visual Studio.
VSCode is a joke versus Visual Studio proper, try to do hot code reloading in Rust, dive into GPU, parallel debugging, trace points, this is the kind of stuff Live++ or VS offer.
