}

Result of a job execution, should be returned by the job handler.

Variants

Success

Job processed successfully.

Failed

Job failed, subject to retry (with BackoffStrategy).

RetryAt(DateTime<Utc>)

Retry (i.e. attempt count incremented) at a specific time. IMPORTANT: Job cannot be retried sooner than the backoff strategy allows

RescheduleAt(DateTime<Utc>)

Reschedule to specific time. Attempt it NOT consumed. Use with caution. Queue’s max_reprocess_count is a safety measure to prevent infinite rescheduling.

HandlerMissing

Handler not found for the job type, status changes to unprocessable.

Critical

Critical failure, job is not retried.

Cancel

Cancel the job (i.e. do not retry anymore), status changes to cancelled.

Unprocessable

Handler can’t process the job (e.g. deserialization failures), status changes to unprocessable.

InternalError

Internal error, same as Failed but looks nicer when handler encountered recoverable error. Attempt is consumed.
