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_cache(&mut self, _cache: HashMap<Id, Vec<u8>>)

Update cached data.

fn update_db_storage(
&mut self,
update: PrefixedMemoryDB<HashFor<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.
