Right, but I'm not basing that purely on these benchmarks. The fact that C++ allows so much, which Rust doesn't, prevents you from transforming code in certain ways that might achieve better performance with identical behavior. I'd just never really thought about the implications of that before. Because of this, in theory, equivalent Rust and C++ code should asymptotically approach a place where Rust is faster, even though at the moment there are many other factors like comparative maturity of the ecosystems.
