Struct indexed_merkle_tree::LeafNode

pub struct LeafNode {
    pub hash: String,
    pub is_left_sibling: bool,
    pub active: bool,
    pub value: String,
    pub label: String,
    pub next: String,
}

Represents a leaf node in the indexed Merkle Tree.

Leaf nodes contain the actual data stored in the tree structure as well as metadata that, among other things, ensures the integrity and order of the tree structure. Each leaf node contains a hash of its metadata consisting of a SHA256 value, an active flag that indicates whether the leaf is active or not and links to neighboring elements for efficient traversal and verification. The links lead to the label field which is also a SHA256 value, making it sortable, which is crucial for e.g. Non-Membership proofs. For more information see https://eprint.iacr.org/2021/1263.pdf.

Fields:

• hash: The hash of the values below, expect of the is_left_sibling-value.
• is_left_sibling: Indicates if this node is a left child in its parent node.
• active: Status flag to indicate if the node is active in the tree.
• value: The actual data value stored in the node.
• label: A unique identifier for the node. This is used to sort by size and to link nodes together.
• next: A reference to the next node in the tree.

Fields

hash: String

is_left_sibling: bool

active: bool

value: String

label: String

next: String
