Struct diem_sdk::types::proof::definition::EventProof

pub struct EventProof<T> { /* fields omitted */ }

The complete proof used to authenticate a contract event. This structure consists of the AccumulatorProof from LedgerInfo to TransactionInfo, the TransactionInfo object and the AccumulatorProof from event accumulator root to the event.

Implementations

impl<T> EventProof<T> where
    T: TransactionInfoTrait, 

pub fn new(
    transaction_info_with_proof: TransactionInfoWithProof<T>,
    transaction_info_to_event_proof: AccumulatorProof<EventAccumulatorHasher>
) -> EventProof<T>

Constructs a new EventProof using given ledger_info_to_transaction_info_proof, transaction_info and transaction_info_to_event_proof.

pub fn transaction_info_with_proof(&self) -> &TransactionInfoWithProof<T>

Returns the transaction_info_with_proof object in this proof.

pub fn verify(
    &self,
    ledger_info: &LedgerInfo,
    event_hash: HashValue,
    transaction_version: u64,
    event_version_within_transaction: u64
) -> Result<(), Error>

Verifies that a given event is correct using provided proof.
