Package: @imqueue/job 3.0.3 — generated reference, not hand-written

Whether a job is handed to a worker under a lock, so that a worker dying before it starts does not take the job with it.

**Signature:**

```typescript
safe?: boolean;
```

## Default Value

true

## Remarks

When safe delivery is enabled a job is moved atomically out of the queue into a worker-owned key as it is popped, so a process that dies before it even starts on that job leaves the job data behind to be re-queued for another worker instead of losing it.

The guarantee covers that hand-off and not the processing: the key is released as soon as the job reaches the handler, so a worker killed part-way through `onPop` loses that attempt. Jobs are delivered at-least-once, so handlers should be idempotent.

Note this defaults to `true` here while `@imqueue/core` defaults it to `false` — a job queue is the case where the extra round-trip is worth it.
