Trait nmt_rs::simple_merkle::tree::MerkleHash

pub trait MerkleHash {
    type Output: Debug + PartialEq + Eq + Clone + Default + Hash + Ord;

    const EMPTY_ROOT: Self::Output;

    // Required methods
    fn hash_leaf(&self, data: &[u8]) -> Self::Output;
    fn hash_nodes(&self, l: &Self::Output, r: &Self::Output) -> Self::Output;
}

A trait for hashing data into a merkle tree

Required Associated Types

type Output: Debug + PartialEq + Eq + Clone + Default + Hash + Ord

The output of this hasher.

Required Associated Constants

const EMPTY_ROOT: Self::Output

The hash of the empty tree. This is often defined as the hash of the empty string.

Required Methods

fn hash_leaf(&self, data: &[u8]) -> Self::Output

Hashes data as a “leaf” of the tree. This operation should be domain separated.

fn hash_nodes(&self, l: &Self::Output, r: &Self::Output) -> Self::Output

Hashes two digests into one. This operation should be domain separated.

Object Safety

This trait is not object safe.
