Trait 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 Constants

const EMPTY_ROOT: Self::Output

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

Required Associated Types

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

The output of this hasher.

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl MerkleHash for TmSha2Hasher

const EMPTY_ROOT: Self::Output

type Output = [u8; 32]

impl<const NS_ID_SIZE: usize> MerkleHash for NamespacedSha2Hasher<NS_ID_SIZE>

const EMPTY_ROOT: NamespacedHash<NS_ID_SIZE>

type Output = NamespacedHash<NS_ID_SIZE>
