Types

type CreateWorkflowCASPredicate 

type CreateWorkflowCASPredicate struct {
	RunID            string
	LastWriteVersion int64
}

type MutableStateConsistencyPredicate 

type MutableStateConsistencyPredicate func(mutableState workflow.MutableState) bool

func HistoryEventConsistencyPredicate 

func HistoryEventConsistencyPredicate(
	eventID int64,
	eventVersion int64,
) MutableStateConsistencyPredicate

type UpdateWorkflowAction 

type UpdateWorkflowAction struct {
	Noop               bool
	CreateWorkflowTask bool
}

type UpdateWorkflowActionFunc 

type UpdateWorkflowActionFunc func(WorkflowContext) (*UpdateWorkflowAction, error)

func ApplyWorkflowIDReusePolicy 

func ApplyWorkflowIDReusePolicy(
	prevStartRequestID,
