Implementations

impl<F: PrimeField, H: FieldHasher<F>, const N: usize> Path<F, H, N>

pub fn check_membership(
    &self,
    root_hash: &F,
    leaf: &F,
    hasher: &H
) -> Result<bool, Error>

Takes in an expected root_hash and leaf-level data (i.e. hashes of secrets) for a leaf and checks that the leaf belongs to a tree having the expected hash.

pub fn calculate_root(&self, leaf: &F, hasher: &H) -> Result<F, Error>

Assumes leaf contains leaf-level data, i.e. hashes of secrets stored on leaf-level.

pub fn get_index(&self, root_hash: &F, leaf: &F, hasher: &H) -> Result<F, Error>

Given leaf data determine what the index of this leaf must be in the Merkle tree it belongs to. Before doing so check that the leaf does indeed belong to a tree with the given root_hash
