Functions

end_prefix

For a given start prefix (inclusive), returns the correct end prefix (non-inclusive). This assumes the key bytes are ordered in lexicographical order. Since key length is not limited, for some case we return None because there is no bounded limit (every keys in the serie [], [255], [255, 255] …).
