source · [−]

pub struct MerklePath<P: MerkleParameters> {
    pub parameters: Arc<P>,
    pub path: Vec<MerkleTreeDigest<P>>,
    pub leaf_index: u64,
}

Expand description

Stores the hashes of a particular path (in order) from leaf to root. Our path is_left_child() if the boolean in path is true.

Fields

parameters: Arcpath: Vec<MerkleTreeDigest>leaf_index: u64

Implementations

source

impl<P: MerkleParameters> MerklePath

source

pub fn verify<L: ToBytes>(
 &self,
 root_hash: &MerkleTreeDigest,
 leaf: &L
) -> Result<bool, MerkleError>

source

pub fn position_list(&self) -> impl Iterator<Item = bool> + '_

The position of on_path node in leaf_and_sibling_hash and non_leaf_and_sibling_hash_path. position[i] is 0 (false) iff ith on-path node from top to bottom is on the left.

This function simply converts self.leaf_index to boolean array in big endian form.
