The ownership model is Rust's core innovation. Every heap allocation has exactly one owner — the variable binding that "holds" it. Ownership can be moved to another binding, at which point the original is invalidated. It can never be silently copied (unless the type implements Copy).

While each of these is not wrong in isolation, together they are. If we are talking about data stored on the heap that last bit is not true. Types that hold a raw pointer cannot be made Copy. Only simple types can be made Copy, ones that don't own any non direct data and as such can be stored on the stack and simply memcpyed to get a copy.
