Returning KeyNode<&Self, B> makes storage of KeyNode pretty hard

[janstarke]

Hi, I currently try to use this library in a tool of mine (https://github.com/janstarke/regview). However, I've a lot of trouble while storing KeyNodes in a datastructure, because they need to have a reference lifetime in their generic parameters:

struct MyDataStructure<'a> {
  current_node: Rc<RefCell<KeyNode<&'a Hive<MyByteSlice>, MyByteSlice>>>
}

Is there a way to change the API, so that the caller chooses which DeRef-implementation shall be used? I could imagine that one preferably used Rc<Hive> or something similar when building dynamic data structures.

Kind regards, Jan

Using custom type without lifetime parameters solves a lot these issues. However, this requires that this type can implement zerocopy::ByteSlice, which is forbidden. See #3 as idea of how to solve this
