pub struct AccumulatorRangeProof<H> { /* private fields */ }
Expand description

A proof that is similar to AccumulatorProof, but can be used to authenticate a range of leaves. For example, given the following accumulator:

                root
               /     \
             /         \
           /             \
          o               o
        /   \           /   \
       /     \         /     \
      X       o       o       Y
     / \     / \     / \     / \
    o   o   a   b   c   Z   o   o

if the proof wants to show that [a, b, c] exists in the accumulator, it would need X on the left and Y and Z on the right.

Implementations§

§

impl<H> AccumulatorRangeProof<H>where H: CryptoHasher,

pub fn new( left_siblings: Vec<HashValue, Global>, right_siblings: Vec<HashValue, Global> ) -> AccumulatorRangeProof<H>

Constructs a new AccumulatorRangeProof using left_siblings and right_siblings.

pub fn new_empty() -> AccumulatorRangeProof<H>

Constructs a new AccumulatorRangeProof for an empty list of leaves.

pub fn left_siblings(&self) -> &Vec<HashValue, Global>

Get all the left siblngs.

pub fn right_siblings(&self) -> &Vec<HashValue, Global>

Get all the right siblngs.

pub fn verify( &self, expected_root_hash: HashValue, first_leaf_index: Option<u64>, leaf_hashes: &[HashValue] ) -> Result<(), Error>

Verifies the proof is correct. The verifier needs to have expected_root_hash, the index of the first leaf and all of the leaves in possession.
