Struct EventProof

Source 
pub struct EventProof { /* private fields */ }
Expand description

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§
