> At this point, I kind of feel like, if you're writing safe C or C++, being mindful of where the data goes and why, you're pretty much writing Rust that compiles. Exactly. If you're using modern c++ and you actually know what's undefined behavior and what's not, you're doing rust. The only difference is c++ compilers don't error out on the undefined behavior. Actually it wouldn't be that hard to write a c++ compiler that errored out in this way. unfortunately, it'd break all c++ programs today.
