in rust how do things like Box::new and Vec::new allocate/move their contents to the heap

also in C you explicitly allocate on the heap, whereas in rust is feels like everything is on the stack except smart pointer types (Box, Rc, Vec, String, etc) magically put their contents on the heap

*inner_raw_pointer = value In release builds the copy will be optimized away, allocating on the heap directly instead of memcpying a stack value

The pointer will come from malloc, same as in C. You can customize the allocator used with the #[global_allocator] attribute
