I am using Rust since 2016 productively... before I dabbled with it.

Rust is not compiling any slower than a comparable C++ codebase for me.

It is compiling much slower than a managed language like Kotlin, C# etc. though. Which is an unfair comparison anyway.

The problem with e.g. gamedev is the iteration cycles. It's very creative work and not so much your average engineering job (apart form game engine dev).

But again, that's an unfair comparison, because even in Unity and many if not most other game engines, there is a scripting language that is used for most of the game logic, that doesn't need hyper performance...

Still, when compared to such languages, Rust indeed does compile slowly AND one has to say: Rust is selling itself not only as a safe, blazingly fast systems programming language these days, but it also is used for its type system etc. and then, when you come from a managed language, compile times really suck.

(Although debug builds are better, they are not an option for game dev for example, because the binary is just too slow then... 200fps vs. 20 :X)
