RefCell<Rc<?>> vs Rc<RefCell<?>> in Chapter 15 of the Rust Book #54531
Description
Chapter 15.6 of the Rust Book includes the following code:
struct Node {
value: i32,
parent: RefCell<Weak<Node>>,
children: RefCell<Vec<Rc<Node>>>,
}
This has a Rc inside a RefCell, but the pattern in other places and the previous section is put the RefCell inside the Rc. It would be nice if the book either used the more common idiom or explained why the rationale for not doing it.
