Struct diem_sdk::types::proof::definition::AccumulatorRangeProof[][src]

pub struct AccumulatorRangeProof<H> { /* fields omitted */ }
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

Constructs a new AccumulatorRangeProof using left_siblings and right_siblings.

Constructs a new AccumulatorRangeProof for an empty list of leaves.

Get all the left siblngs.

Get all the right siblngs.

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.
