The rules can be enforced by a static code checker.

That is really not very different of rules enforced by the Rust compiler.

For someone who does a fresh start, using a Rust compiler may ensure safer programs out of the box, but that does not mean that the same results cannot be achieved by alternative means when using other languages, when the use of those languages makes sense for other reasons, and it is worthwhile to invest resources in making appropriate libraries and tooling.

In general, I recommend against the use of C++ in new projects, but I see much too often claims about things that are supposedly difficult or impossible to do in C++, which are just false.
