}

Fields

id: UID

Object UID for adding dynamic fields that are used as pointers to nodes.

size: u64

Number of key-value pairs in the map.

counter: u64

Counter for creating another node as a dynamic field.

root: u64

Pointer to the root node, which is a branch or a leaf.

first: u64

Pointer to first leaf.

branch_min: u64

Minimal number of kids in a non-root branch; must satisfy 2 <= branch_min <= branch_max / 2.

branches_merge_max: u64

Maximal number of kids in a branch, which is merge of two branches; must satisfy 2 * branch_min <= branches_merge_max <= branch_max.

branch_max: u64

Maximal number of kids in a branch.

leaf_min: u64

Minimal number of elements in a non-root leaf; must satisfy 2 <= leaf_min <= (leaf_max + 1) / 2.

leaves_merge_max: u64

Maximal number of elements in a leaf, which is merge of two leaves; must satisfy 2 * leaf_min - 1 <= leaves_merge_max <= leaf_max.

leaf_max: u64

Maximal number of elements in a leaf.
