Struct mohan::merkle::Proof

pub struct Proof<T: Eq + Clone + AsRef<[u8]>> { /* fields omitted */ }

Merkle tree inclusion proof for data element, for which item = Leaf(Hash(Data Item)).

Lemma layout:

[ item h1x h2y h3z ... root ]

Proof validation is positioned hash against lemma path to match root hash.

Methods

impl<T: Eq + Clone + AsRef<[u8]>> Proof<T>

pub fn new(hash: Vec<T>, path: Vec<bool>) -> Proof<T>

Creates new MT inclusion proof

pub fn item(&self) -> T

Return proof target leaf

pub fn root(&self) -> T

Return tree root

pub fn validate<A: Algorithm<T>>(&self) -> bool

Verifies MT inclusion proof

pub fn validate_with_data<A: Algorithm<T>>(
    &self,
    leaf_data: &dyn Hashable<A>
) -> bool

Verifies MT inclusion proof and that leaf_data is the original leaf data for which proof was generated.

pub fn path(&self) -> &Vec<bool>

Returns the path of this proof.

pub fn lemma(&self) -> &Vec<T>

Returns the lemma of this proof.
