Arena based memory tree structure

Trait Implementations

impl<T> BaseTree<T> for AVLTree<T>

where T: PartialOrd + PartialEq + Debug,

fn get(&self, val: usize) -> &Self::MNode

In order to return a reference to a value of a vector contained within a refcell, a raw pointer is used. The unsafe code could be avoided by replacing each call to self.get(n) with &self.data.borrow()[n] and each call to self.get_mut(n) with &mut self.data.borrow()[n]. This allows us to do the same thing with less keystrokes. It does make the program not thread-safe, but a this data structure is a pretty terrible choice for a multi-threaded data structure anyways, since re-balancing can require that most of the tree be locked to one thread during an insertion or deletion
