If I need to update a record, I think I need to do a get + unwrap_or_default, modify, and then insert? Does it cost me a lookup twice? Would it make sense to have an API like BTreeMap::entry?

Hmmm... insert_reserve is kind of like it, but I don't see an Option anywhere, and the value_len doesn't seem like what I have.
