> One thing Rust's vector guarantees that C++ doesn't is that Rust's vector will not store elements inline; anything (with nonzero size) you push into it will be heap allocated. Does C++ really not guarantee this? If yes then I probably have written quite a bit of "broken" code, which assumes that element addresses stay constant during moves of the container. std::vector<A> vec1; // And initialize it A* a = &vec1[0]; auto vec2 = std::move(vec1); A* b = &vec2[0]; assert(a == b);
