Database transaction

Trait Implementations

impl<Block: BlockT> BlockImportOperation<Block> for BlockImportOperation<Block>

type State = RecordStatsState<RefTrackingState<Block>, Block>

Associated state backend type.

fn state(&self) -> ClientResult<Option<&Self::State>>

Returns pending state.

fn set_block_data( &mut self, header: Block::Header, body: Option<Vec<Block::Extrinsic>>, indexed_body: Option<Vec<Vec<u8>>>, justifications: Option<Justifications>, leaf_state: NewBlockState ) -> ClientResult<()>

Append block data to the transaction.

fn update_db_storage( &mut self, update: PrefixedMemoryDB<HashingFor<Block>> ) -> ClientResult<()>

Inject storage data into the database.

fn reset_storage( &mut self, storage: Storage, state_version: StateVersion ) -> ClientResult<Block::Hash>

Inject storage data into the database replacing any existing data.

fn set_genesis_state( &mut self, storage: Storage, commit: bool, state_version: StateVersion ) -> ClientResult<Block::Hash>

Set genesis state. If commit is false the state is saved in memory, but is not written to the database.

fn insert_aux<I>(&mut self, ops: I) -> ClientResult<()>where I: IntoIterator<Item = (Vec<u8>, Option<Vec<u8>>)>,

Insert auxiliary keys.

fn update_storage( &mut self, update: StorageCollection, child_update: ChildStorageCollection ) -> ClientResult<()>

Set storage changes.

fn update_offchain_storage( &mut self, offchain_update: OffchainChangesCollection ) -> ClientResult<()>

Write offchain storage changes to the database.

fn mark_finalized( &mut self, block: Block::Hash, justification: Option<Justification> ) -> ClientResult<()>

Mark a block as finalized.

fn mark_head(&mut self, hash: Block::Hash) -> ClientResult<()>

Mark a block as new head. If both block import and set head are specified, set head overrides block import’s best block rule.

fn update_transaction_index( &mut self, index_ops: Vec<IndexOperation> ) -> ClientResult<()>

Add a transaction index operation.
