Struct merkle::Proof

pub struct Proof<T> {
    pub algorithm: &'static Algorithm,
    pub root_hash: Vec<u8>,
    pub lemma: Lemma,
    pub value: T,
}

An inclusion proof represent the fact that a value is a member of a MerkleTree with root hash root_hash, and hash function algorithm.

Fields

algorithm: &'static Algorithm

The hashing algorithm used in the original MerkleTree

root_hash: Vec<u8>

The hash of the root of the original MerkleTree

lemma: Lemma

The first Lemma of the Proof

value: T

The value concerned by this Proof

Methods

impl<T> Proof<T>

pub fn new(     algorithm: &'static Algorithm,     root_hash: Vec<u8>,     lemma: Lemma,     value: T ) -> Self

Constructs a new Proof

pub fn validate(&self, root_hash: &[u8]) -> bool

Checks whether this inclusion proof is well-formed, and whether its root hash matches the given root_hash.
