Not a Rust dev, but from what I understand, the lifetime tracking of Rust means you can safely give out references to stack allocated memory without worrying about corruption/segfaults/use-after-free errors or the like, because the compiler will catch it if that is possible, whereas in C++ you'd usually want to do defensive copying in situations like that. So in some cases, Rust actually allows you to fearlessly do things the most efficient way in a way you'd not be able to do in C++.
