A lot of things did happen. One of them is having the option to check the source which is much faster than compiling. 99% of the time you're compiling code in rust is to run the borrow checker and fix those errors.
That's indeed something where Rust is a lot better than C++. But for many projects (like games or GUI apps) you'll need to iterate with changes which can only be seen in the final product. So you'll need a complete build to run the binary.
Fair enough. However games and GUI apps are still a small percentage of applications developed in rust. I want that to change, of course. I just wanted to point that out.
I'm personally writing a game in Rust but the main logic is written in a compile-to-JS language and uses V8, so the issue doesn't affect me.
