You say you are "summarizing" something but instead you seem to have just injected your opinion that C++ is "notably more performant than C and by implication Rust".

It's true that you can express many things in C++ -- the problem is that the language deliberately doesn't distinguish whether the things you've expressed are nonsense, so you might well have written total nonsense and you only find out when, much later, diagnosing a real world event you discover oh, this is nonsense, why did this even compile? Well sorry, it was "more performant" to allow nonsense.
