It’s not a joke. What was described above is pretty much C++'s RAII pattern, which Rust evangelists love to present as a revolutionary Rust invention. Used with smart pointers, it will help avoid use-after-frees. What it doesn’t avoid is null pointer exceptions (you can
std::movea unique_ptr and still access it, it’ll just be nullptr), but those will typically “just” be a crash rather than a gaping security hole.That is not to say Rust doesn’t have its own innovations on top of that (notably that the compiler stringently enforces this pattern), and C++ does give you many more ways to break the rules and shoot yourself in the foot than Rust does.
