Struct MerkleTree

pub struct MerkleTree<T> {
    pub algorithm: Sha3,
    /* private fields */
}

A Merkle tree is a binary tree, with values of type T at the leafs, and where every internal node holds the hash of the concatenation of the hashes of its children nodes.

Fields

algorithm: Sha3

The hashing algorithm used by this Merkle tree

Implementations

impl<T> MerkleTree<T>

pub fn from_vec<H>(algorithm: Sha3, values: Vec<T>) -> Self

where T: Hashable, Sha3: HashUtils<H>, H: AsRef<[u8]>,

Constructs a Merkle Tree from a vector of data blocks. Returns None if values is empty.

pub fn root_hash(&self) -> &Vec<u8>

Returns the root hash of Merkle tree

pub fn height(&self) -> usize

Returns the height of Merkle tree

pub fn count(&self) -> usize

Returns the number of leaves in the Merkle tree

pub fn is_empty(&self) -> bool

Returns whether the Merkle tree is empty or not

pub fn gen_proof<H>(&self, value: T) -> Option<Proof<T>>

where T: Hashable, Sha3: HashUtils<H>, H: AsRef<[u8]>,

Generate an inclusion proof for the given value. Returns None if the given value is not found in the tree.

pub fn iter(&self) -> LeavesIterator<'_, T>

Creates an Iterator over the values contained in this Merkle tree.

Trait Implementations

impl<T: Clone> Clone for MerkleTree<T>

fn clone(&self) -> MerkleTree<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T> IntoIterator for &'a MerkleTree<T>

fn into_iter(self) -> Self::IntoIter

Creates a borrowing Iterator over the values contained in this Merkle tree.

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = LeavesIterator<'a, T>

Which kind of iterator are we turning this into?

impl<T> IntoIterator for MerkleTree<T>

fn into_iter(self) -> Self::IntoIter

Creates a consuming iterator, that is, one that moves each value out of the Merkle tree. The tree cannot be used after calling this.

type Item = T

The type of the elements being iterated over.

type IntoIter = LeavesIntoIterator<T>

Which kind of iterator are we turning this into?
