C++ vs. Rust is a tricky question. C++ is easier to write in, but it's harder to get programs working in it. Rust is harder to write, but it's much more likely that your first execution is going to do something useful. But they're of comparable complexity.
Second this. Rust also follows some habits of C++ like verbose syntax and accidental complexity. There was an article recently where a Rust port of a C++ application ended up being comparable in lines of code.
