I'm not following, what is Rust doing exactly? Coupling schema / layout with lifetime management? If that's what you mean I would like to disagree about the "great results" because of a gut feeling, and possibly the disagreement could in theory be justified with build times, or viewpoints on maintainability or whatever. But unfortunately I have no basis for doing so. I don't understand Rust well. And have very little experience, expect failing at compiling some projects and their 500 dependencies a couple times...
