Type Alias RewardMerkleNode 

type RewardMerkleNode = MerkleNode<RewardAmount, RewardAccountV2, KeccakNode>;

Merkle node containing a reward amount leaf.

Internal representation of tree nodes. Can be Empty, Leaf (account + amount), Branch (internal node with children), or ForgettenSubtree (sparse placeholder).

Aliased Type

enum RewardMerkleNode {
    Empty,
    Branch {
        value: KeccakNode,
        children: Vec<Arc<MerkleNode<RewardAmount, RewardAccountV2, KeccakNode>>>,
    },
    Leaf {
        value: KeccakNode,
        pos: RewardAccountV2,
        elem: RewardAmount,
    },
    ForgettenSubtree {
        value: KeccakNode,
    },
}

Variants

Empty

An empty subtree with no elements.

Branch

An internal branching node with children.

Fields

value: KeccakNode

Merkle hash value of this subtree

children: Vec<Arc<MerkleNode<RewardAmount, RewardAccountV2, KeccakNode>>>

All its children nodes

Leaf

A leaf node containing an element.

Fields

value: KeccakNode

Merkle hash value of this leaf

pos: RewardAccountV2

Index of this leaf in the tree

elem: RewardAmount

Associated element stored in this leaf

ForgettenSubtree

A subtree that has been forgotten from memory.

This variant retains only the hash value of the subtree, allowing the tree commitment to remain valid while reducing memory usage. Forgotten subtrees can be restored using the remember_internal method if a valid proof is provided.

Fields

value: KeccakNode

Merkle hash value of this forgotten subtree
