Struct hycon_rust::common::merkle::MerkleTree

pub struct MerkleTree { /* fields omitted */ }

A merkle tree

Methods

impl MerkleTree

pub fn length_for(length: usize) -> usize

Calculate and return the length of vector required to build a tree for the input vector length

pub fn couple_hash(left: &Blake2bResult, right: &Blake2bResult) -> Blake2bResult

Calculate a hash value for the concatenated value of two hash values

pub fn empty_tree() -> MerkleTree

Construct a tree that has only one element containing the hash value of empty byte vector

pub fn from(hashes: Vec<Blake2bResult>) -> MerkleTree

Construct the merkle tree containing the input vector and their ancestors that are built with couple_hash

Example

let input = Vec::new();

input.push(hash(tx_object,32));

let merkle_tree=MerkleTree::from(input);

pub fn root(&self) -> &[u8]

Return the hash value stored in the root element of this tree

pub fn size(&self) -> usize

Return the size of merkle tree
