|Function||bisect_multi_bytes||Perform bisection lookups for keys using byte based addressing.|
Perform bisection lookups for keys using byte based addressing. The keys are looked up via the content_lookup routine. The content_lookup routine gives bisect_multi_bytes information about where to keep looking up to find the data for the key, and bisect_multi_bytes feeds this back into the lookup function until the search is complete. The search is complete when the list of keys which have returned something other than -1 or +1 is empty. Keys which are not found are not returned to the caller. :param content_lookup: A callable that takes a list of (offset, key) pairs and returns a list of result tuples ((offset, key), result). Each result can be one of: -1: The key comes earlier in the content. False: The key is not present in the content. +1: The key comes later in the content. Any other value: A final result to return to the caller. :param size: The length of the content. :param keys: The keys to bisect for. :return: An iterator of the results.
