I could have added a helper function like Rust that would also return an error code on an incorrect digit, and look much the same
The point is that Rust has expression-level syntactic sugar for what in C would be a pile of if (foo < 0) return foo;

You could do that with a macro in C, but not with a function. You could use exceptions in C++ of course (but who uses those?)

I understand, it's nice to have the concept of a Maybe value. I was just trying to write the code more as a fair side-by-side to the Rust

Yes, I agree that your version is more fair. That's why I said it wasn't that great a comparison initially.
