Required methods

fn setup<R: Rng>(rng: &mut R) -> Self

Setup the MerkleParameters

fn crh(&self) -> &Self::H

Returns the collision-resistant hash function used by the Merkle tree.

fn parameters(&self) -> &<<Self as MerkleParameters>::H as CRH>::Parameters

Returns the collision-resistant hash function parameters used by the Merkle tree.

Provided methods

fn hash_leaf<L: ToBytes>(
    &self,
    leaf: &L,
    buffer: &mut [u8]
) -> Result<<Self::H as CRH>::Output, MerkleError>

Returns the hash of a given leaf.

fn hash_inner_node(
    &self,
    left: &<Self::H as CRH>::Output,
    right: &<Self::H as CRH>::Output,
    buffer: &mut [u8]
) -> Result<<Self::H as CRH>::Output, MerkleError>
