Interface: LaneSignalHandlerConfig<TIn, TStepIds, TPayload>

Defined in: ast/lane-node.ts:82

Live signal steering and step rewind handler configuration for a LaneNode.

Executes the Hierarchical Rewind Drain Barrier when signal correlates to an active run, reduces the run input via updateMapper, runs onRewind, and rewinds execution to rewindToStepId.

Type Parameters

Type Parameter	Default type	Description
TIn	unknown	Validated lane work item input type.
TStepIds extends string	string	Union of literal step and branch IDs in the lane's flow.
TPayload	unknown	Signal payload type.
