43 * maple_tree node explained
44 *
45 * Each node type has a number of slots for entries and a number of
slots for
46 * pivots. In the case of dense nodes, the pivots are implied by the
position
47 * and are simply the slot index + the minimum of the node.
48 *
49 * In regular B-Tree terms, pivots are called keys. The term pivot is
used to
50 * indicate that the tree is specifying ranges, Pivots may appear in
the
51 * subtree with an entry attached to the value where as keys are unique
to a
52 * specific position of a B-tree. Pivot values are inclusive of the
slot with
53 * the same index.
54 *
55 *
56 * The following illustrates the layout of a range64 nodes slots and
pivots.
57 *
58 * _________________________________
59 * Slots -> | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
