Expand description
Cursor over the posting entries of an mmap’d index.
The mmap file stores, per entry, a record id, a weight and a
max_next_weight ceiling. The cursor folds that ceiling into the
inclusive form used here (tail_max = max(weight, max_next_weight)),
which is correct whether the file’s ceiling includes the entry itself or
only the entries after it.
