source · [−]

pub struct AccumulatorProof<H> { /* private fields */ }

Expand description

A proof that can be used authenticate an element in an accumulator given trusted root hash. For example, both LedgerInfoToTransactionInfoProof and TransactionInfoToEventProof can be constructed on top of this structure.

Implementations

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

pub fn new(siblings: Vec<HashValue>) -> Self

Constructs a new AccumulatorProof using a list of siblings.

pub fn siblings(&self) -> &[HashValue]

Returns the list of siblings in this proof.

pub fn verify(
    &self,
    expected_root_hash: HashValue,
    element_hash: HashValue,
    element_index: u64
) -> Result<()>

Verifies an element whose hash is element_hash and version is element_version exists in the accumulator whose root hash is expected_root_hash using the provided proof.
