pub struct BlockImportOperation<Block: BlockT> { /* fields omitted */ }

In-memory operation.

Trait Implementations

impl<Block: BlockT> BlockImportOperation<Block> for BlockImportOperation<Block> where
    Block::Hash: Ord, 

type State = InMemoryBackend<HashFor<Block>>

Associated state backend type.

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

Returns pending state.

fn set_block_data(
    &mut self,
    header: <Block as BlockT>::Header,
    body: Option<Vec<<Block as BlockT>::Extrinsic>>,
    _indexed_body: Option<Vec<Vec<u8>>>,
    justifications: Option<Justifications>,
    state: NewBlockState
) -> Result<()>

Append block data to the transaction.

fn update_cache(&mut self, _cache: HashMap<CacheKeyId, Vec<u8>>)

Update cached data.

fn update_db_storage(
    &mut self,
    update: <InMemoryBackend<HashFor<Block>> as StateBackend<HashFor<Block>>>::Transaction
) -> Result<()>

Inject storage data into the database.

fn update_changes_trie(
    &mut self,
    _update: ChangesTrieTransaction<HashFor<Block>, NumberFor<Block>>
) -> Result<()>

Inject changes trie data into the database.

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

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

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

Inject storage data into the database replacing any existing data.

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

Insert auxiliary keys.

fn update_storage(
    &mut self,
    _update: StorageCollection,
    _child_update: ChildStorageCollection
) -> Result<()>

Set storage changes.

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

Mark a block as finalized.

fn mark_head(&mut self, block: BlockId<Block>) -> Result<()>

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: Vec<IndexOperation>
) -> Result<()>

Add a transaction index operation.

fn update_offchain_storage(
    &mut self,
    _offchain_update: OffchainChangesCollection
) -> Result<()>

Write offchain storage changes to the database.
