impl<'a, Y: SystemBasedKernelApi> KernelSubstateApi<SystemLockData> for SystemService<'a, Y>

fn kernel_mark_substate_as_transient( &mut self, node_id: NodeId, partition_num: PartitionNumber, key: SubstateKey, ) -> Result<(), RuntimeError>

Marks a substate as transient, or a substate which was never and will never be persisted

fn kernel_open_substate_with_default<F: FnOnce() -> IndexedScryptoValue>( &mut self, node_id: &NodeId, partition_num: PartitionNumber, substate_key: &SubstateKey, flags: LockFlags, default: Option<F>, data: SystemLockData, ) -> Result<SubstateHandle, RuntimeError>

Locks a substate to make available for reading and/or writing

fn kernel_get_lock_data( &mut self, lock_handle: SubstateHandle, ) -> Result<SystemLockData, RuntimeError>

Retrieves info related to a lock

fn kernel_close_substate( &mut self, lock_handle: SubstateHandle, ) -> Result<(), RuntimeError>

Drops the handle on some substate, if the handle is a force write, updates are flushed. No updates should occur if an error is returned.

fn kernel_read_substate( &mut self, lock_handle: SubstateHandle, ) -> Result<&IndexedScryptoValue, RuntimeError>

Reads the value of the substate locked by the given lock handle

fn kernel_write_substate( &mut self, lock_handle: SubstateHandle, value: IndexedScryptoValue, ) -> Result<(), RuntimeError>

Writes a value to the substate locked by the given lock handle

fn kernel_set_substate( &mut self, node_id: &NodeId, partition_num: PartitionNumber, substate_key: SubstateKey, value: IndexedScryptoValue, ) -> Result<(), RuntimeError>

Sets a value to a substate without checking for the original value.

fn kernel_remove_substate( &mut self, node_id: &NodeId, partition_num: PartitionNumber, substate_key: &SubstateKey, ) -> Result<Option<IndexedScryptoValue>, RuntimeError>

Removes a substate from a node and returns the original value.

fn kernel_scan_sorted_substates( &mut self, node_id: &NodeId, partition_num: PartitionNumber, limit: u32, ) -> Result<Vec<(SortedKey, IndexedScryptoValue)>, RuntimeError>

Reads substates under a node in sorted lexicographical order

fn kernel_scan_keys<K: SubstateKeyContent>( &mut self, node_id: &NodeId, partition_num: PartitionNumber, limit: u32, ) -> Result<Vec<SubstateKey>, RuntimeError>

fn kernel_drain_substates<K: SubstateKeyContent>( &mut self, node_id: &NodeId, partition_num: PartitionNumber, limit: u32, ) -> Result<Vec<(SubstateKey, IndexedScryptoValue)>, RuntimeError>

fn kernel_open_substate( &mut self, node_id: &NodeId, partition_num: PartitionNumber, substate_key: &SubstateKey, flags: LockFlags, lock_data: L, ) -> Result<SubstateHandle, RuntimeError>
