Convenience methods for direct SubstateDatabase readers.

Required Methods

fn get_mapped<M, D>( &self, node_id: &NodeId, partition_num: PartitionNumber, substate_key: &SubstateKey ) -> Option<D>

where M: DatabaseKeyMapper, D: ScryptoDecode,

Gets a scrypto-decoded value by the given business key.

fn list_mapped<M, D, K>( &self, node_id: &NodeId, partition_num: PartitionNumber ) -> Box<dyn Iterator<Item = (SubstateKey, D)> + '_>

where M: DatabaseKeyMapper, D: ScryptoDecode, K: SubstateKeyContent + 'static,

Lists fully-mapped entries (i.e. business substate keys and scrypto-decoded values) of the given node partition.
