I believe you mean RAII. Though I suppose I've seen no evidence against the notion that Rust likes the Recording Industry Association of America. Jokes aside, I think the biggest difference between Rust and C++ lies in metaprogramming and generics. Rust macros are a trip. Rust's sum types and traits are also much more deeply integrated into the syntax of the language than std::variant or concepts.
