WebIf you're using smart pointers, then in order to free the memory associated with A, B & C you need to manually get in there an "break" the circular reference (e.g. using weak_ptr in C++). Garbage collection (typically) works quite differently. Most garbage collectors these days use a reachability test. WebThis situation is very simple to handle with a garbage collector or with manual memory management. Just count the number of B that are using A. However, rust has another way of managing memory via ownership. Does this way of memory management result in another way to handle object A whose (required) lifetime can only be known at runtime?
