An extension trait for tree iterators

Required Methods

fn traverse<StateMut, Find, V>(
    &self,
    state: StateMut,
    find: Find,
    delegate: &mut V
) -> Result<(), Error> where
    Find: for<'a> FnMut(&oid, &'a mut Vec<u8>) -> Option<TreeRefIter<'a>>,
    StateMut: BorrowMut<State>,
    V: Visit, 

Traverse this tree with state being provided to potentially reuse allocations, and find being a function to lookup trees and turn them into iterators.

The delegate implements a way to store details about the traversal to allow paying only for what’s actually used. Since it is expected to store the operation result, unit is returned.
