I think at some level you can’t really get both. The rust compiler is constantly being sped up, but the amount of checking it does simply takes time.
It’s the age old adage “The fastest code is the one that doesn’t exist”. The fastest compilation checks are the ones you don’t do.
So. Compile times?
I’m willing to have slower compile times for more stable software.
Israel’s neighbors have tried to sweep them into the sea 3 times so far. I’d be pretty twitchy if it was me.
