Options accepted by an IMQ service.

**Signature:**

```typescript
export interface IMQServiceOptions extends IMQOptions 
```

## Remarks

Extends the core queue options, so all transport settings — `host`, `port`, `prefix`, `safeDelivery`, `useGzip`, `cluster`, `logger` and the rest — are accepted and forwarded to the queue factory.
