MMR nodes & size -related utilities.
Implementations§
§impl NodesUtils
impl NodesUtils
pub fn new(no_of_leaves: u64) -> NodesUtils
pub fn new(no_of_leaves: u64) -> NodesUtils
Create new instance of MMR nodes utilities for given number of leaves.
pub fn number_of_peaks(&self) -> u64
pub fn number_of_peaks(&self) -> u64
Calculate number of peaks in the MMR.
pub fn number_of_leaves(&self) -> u64
pub fn number_of_leaves(&self) -> u64
Return the number of leaves in the MMR.
pub fn leaf_index_that_added_node(node_index: u64) -> u64
pub fn leaf_index_that_added_node(node_index: u64) -> u64
Calculate LeafIndex
for the leaf that added node_index
to the MMR.
pub fn leaf_index_to_leaf_node_index(leaf_index: u64) -> u64
pub fn leaf_index_to_leaf_node_index(leaf_index: u64) -> u64
Translate a LeafIndex
to its leaf NodeIndex
.
pub fn right_branch_ending_in_leaf(leaf_index: u64) -> Vec<u64>
pub fn right_branch_ending_in_leaf(leaf_index: u64) -> Vec<u64>
Starting from any leaf index, get the sequence of positions of the nodes added to the mmr when this leaf was added (inclusive of the leaf’s position itself). That is, all of these nodes are right children of their respective parents.
