The new Windows sudo tool is a good example of this. It was written in Rust and, as far as I know, no one has found any memory safety errors. Some large categories of potential vulnerabilities were eliminated by construction, which is great. Unfortunately, that didn’t stop it having a terrible security architecture that allowed remote privilege elevation. You don’t just need competent Rust programmers, you need competent Rust programmers who are domain experts.
