type QueueItemStatus ¶
type QueueItemStatus int32
const ( OperationStatus_Initial QueueItemStatus = 0 OperationStatus_CommitSent QueueItemStatus = 1 OperationStatus_CommitDone QueueItemStatus = 2 OperationStatus_RegisterSent QueueItemStatus = 3 OperationStatus_Completed QueueItemStatus = 4 OperationStatus_CommitError QueueItemStatus = 5 OperationStatus_RegisterError QueueItemStatus = 6 OperationStatus_Error QueueItemStatus = 7 )
when adding new status, don't forget to update these function: 1. StatusToState 2. NameRegisterMoveStateNext (IsStopProcessing in some rare cases)
type QueueItemType ¶
type QueueItemType int32
const ( ItemType_NameRegister QueueItemType = 1 ItemType_NameRenew QueueItemType = 2 )
