Weak<T>
A non-owning reference that prevents reference cycles
Core Idea
[[weak|Weak<T>]] is the weak reference pointer that points into shared structures without increasing the strong reference count. That makes it important for parent-child graphs and other shapes where full ownership cycles would leak memory.
Why It Matters Here
Mathbong uses Weak when explaining Rc<T> cycles and graph-like structures. The key idea is simple: keep an access path without claiming ownership.
