Architecture
Fundamentally, LinkedList is built just the way we built the doubly linked list in Chapter 14, Lists, Lists, and More Lists, with the addition of a PhantomData<T> type pointer. Why? This is necessary to inform the compiler about the properties of the type that contains the marker when generics are involved. With it, the compiler can determine a range of things, including drop behavior, lifetimes, and so on. The PhantomData<T> pointer is a zero-size addition, and pretends to own type T content, so the compiler can reason about that.
