Expand description
params for sealing a new block
Fields§
§create_empty: bool
if true, empty blocks(without extrinsics) will be created. otherwise, will return Error::EmptyTransactionPool.
finalize: bool
instantly finalize this block?
parent_hash: Option<<B as BlockT>::Hash>
specify the parent hash of the about-to-created block
sender: Sender<CreatedBlock<<B as BlockT>::Hash>>
sender to report errors/success to the rpc.
pool: Arc<TP>
transaction pool
client: Arc<C>
header backend
env: &'a mut E
Environment trait object for creating a proposer
select_chain: &'a SC
SelectChain object
consensus_data_provider: Option<&'a dyn ConsensusDataProvider<B, Proof = P>>
Digest provider for inclusion in blocks.
block_import: &'a mut BI
block import object
create_inherent_data_providers: &'a CIDP
Something that can create the inherent data providers.
