Expand description
Message sent to the background authorship task, usually by RPC.
Variants§
SealNewBlock
Fields
§
create_empty: bool
if true, empty blocks(without extrinsics) will be created. otherwise, will return Error::EmptyTransactionPool.
§
sender: Sender<CreatedBlock<Hash>>
sender to report errors/success to the rpc.
Tells the engine to propose a new block
if create_empty == true, it will create empty blocks if there are no transactions in the transaction pool.
if finalize == true, the block will be instantly finalized.
FinalizeBlock
Fields
§
hash: Hash
hash of the block
§
justification: Option<EncodedJustification>
finalization justification
Tells the engine to finalize the block with the supplied hash
