Trait Implementations

impl<Block> BlockImportOperation<Block> for BlockImportOperation<Block> where
    Block: Block, 

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

Associated state backend type.

pub fn state(
    &self
) -> Result<Option<&<BlockImportOperation<Block> as BlockImportOperation<Block>>::State>, Error>

Returns pending state.

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

Append block data to the transaction.

pub fn update_cache(
    &mut self,
    _cache: HashMap<[u8; 4], Vec<u8, Global>, RandomState>
)

Update cached data.

pub fn update_db_storage(
    &mut self,
    update: MemoryDB<<<Block as Block>::Header as Header>::Hashing, PrefixedKey<<<Block as Block>::Header as Header>::Hashing>, Vec<u8, Global>, MemCounter<Vec<u8, Global>>>
) -> Result<(), Error>

Inject storage data into the database.

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

Inject storage data into the database replacing any existing data.

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

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

pub fn update_changes_trie(
    &mut self,
    update: (MemoryDB<<<Block as Block>::Header as Header>::Hashing, HashKey<<<Block as Block>::Header as Header>::Hashing>, Vec<u8, Global>, MemCounter<Vec<u8, Global>>>, CacheAction<<<<Block as Block>::Header as Header>::Hashing as Hasher>::Out, <<Block as Block>::Header as Header>::Number>)
) -> Result<(), Error>

Inject changes trie data into the database.

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

Insert auxiliary keys.

pub fn update_storage(
    &mut self,
    update: Vec<(Vec<u8, Global>, Option<Vec<u8, Global>>), Global>,
    child_update: Vec<(Vec<u8, Global>, Vec<(Vec<u8, Global>, Option<Vec<u8, Global>>), Global>), Global>
) -> Result<(), Error>

Set storage changes.

pub fn update_offchain_storage(
    &mut self,
    offchain_update: Vec<((Vec<u8, Global>, Vec<u8, Global>), OffchainOverlayedChange), Global>
) -> Result<(), Error>

Write offchain storage changes to the database.

pub fn mark_finalized(
    &mut self,
    block: BlockId<Block>,
    justification: Option<([u8; 4], Vec<u8, Global>)>
) -> Result<(), Error>

Mark a block as finalized.

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

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

pub fn update_transaction_index(
    &mut self,
    index_ops: Vec<IndexOperation, Global>
) -> Result<(), Error>

Add a transaction index operation.
