Required methods
fn import_header(
&self,
header: <Block as Block>::Header,
cache: HashMap<[u8; 4], Vec<u8>, RandomState>,
state: NewBlockState,
aux_ops: Vec<(Vec<u8>, Option<Vec<u8>>)>
) -> Result<(), Error>
&self,
header: <Block as Block>::Header,
cache: HashMap<[u8; 4], Vec<u8>, RandomState>,
state: NewBlockState,
aux_ops: Vec<(Vec<u8>, Option<Vec<u8>>)>
) -> Result<(), Error>
Store new header. Should refuse to revert any finalized blocks.
Takes new authorities, the leaf state of the new block, and any auxiliary storage updates to place in the same operation.
fn set_head(&self, block: BlockId<Block>) -> Result<(), Error>
Set an existing block as new best block.
fn finalize_header(&self, block: BlockId<Block>) -> Result<(), Error>
Mark historic header as finalized.
fn last_finalized(&self) -> Result<<Block as Block>::Hash, Error>
Get last finalized header.
fn cache(&self) -> Option<Arc<dyn Cache<Block> + 'static>>
Get storage cache.
fn usage_info(&self) -> Option<UsageInfo>
Get storage usage statistics.
