The inline key: yes, it applies to all kinds of integers and strings, and it exposes InlineKey traits that allow you to implement your own inline prefix.

The checklist items: I forget to cross them and they are all implemented, although I think the checklist item has nothing to do with bbtree. but this is definitely a flaw.
