(Safe) Rust is a lot better about the "Pit of Success" design than C++
There are fundamental technical choices to deliver that, but also ergonomic things like notice Rust's []::sort is a stable sort, whereas C++ std::sort is an unstable sort. If you don't know about sort stability in Rust what you wrote works and in C++ you get a nasty surprise.
