Expand description

Immutable key/value store trait for storing/retrieving transactions, effects, and events. Only defines multi_get/multi_put methods to discourage single key/value operations.

Required Methods§

Source

fn multi_get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, transaction_keys: &'life1 [TransactionDigest], effects_keys: &'life2 [TransactionDigest], ) -> Pin<Box<dyn Future<Output = IotaResult<KVStoreTransactionData>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Generic multi_get, allows implementors to get heterogenous values with a single round trip.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,
