wobbly provides the single-threaded rc::Wobbly<T> and thread-safe sync::Wobbly<T> reference-counting pointers that are similar to Weak but provide wobbly-shared ownership of a value of type T, allocated on the heap. Unlike Weak pointers, a group of Wobbly pointers shares one owning (strong) pointer that is released when the first Wobbly of the group is dropped, and Wobbly pointers can thus keep a value alive like std::rc::Rc or std::sync::Arc but can also break cycles by being a non-owning pointer like std::rc::Weak or std::sync::Weak.
