Struct ManualBlockProducer 

pub struct ManualBlockProducer { /* private fields */ }

Cloneable in-process control for producing blocks in manual mode.

Implementations

impl ManualBlockProducer

pub async fn produce_block(&self) -> Result<ProducedBlock, BlockProductionError>

Run one scheduler proposal/commit cycle and await its outcome.

Dropping the returned future before the driver starts the request cancels it. Once scheduler work begins, dropping the future does not cancel the cycle. BlockProductionError::TimedOut, BlockProductionError::OutcomeUnknown, BlockProductionError::ProposalOutcomeUnknown, and BlockProductionError::CommitOutcomeUnknown mean callers must inspect chain state before deciding whether to request another block. Malformed proposal, commit rejection, and consensus-hash errors are also terminal because the scheduler may have retained the proposed candidate. The producer becomes terminal after an indeterminate result so queued requests cannot overlap scheduler work that may still be running.

The current scheduler protocol reports an empty or otherwise non-nominatable mempool as BlockProductionError::SchedulerRejected; it does not expose a distinct empty-mempool outcome.
