When I was messing around Rustlang I noticed the compiler was considerably slower than c++ compiler.
I don’t know how it is today, but there I was already thinking “-imagine this thing compiling a big project like a Unreal game, would be pain”.
If crates are more malleable now would be cool to see some experiments, but my experience those days wasn’t great.
Btw, c++ is already too slow to compile Unreal projects… Rust could be worse.
