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.
