Package: @imqueue/async-logger 3.2.0 — generated reference, not hand-written

Explicit configuration for a [Logger](https://imqueue.org/api/async-logger/latest/async-logger.logger/), replacing what it would otherwise read from the environment.

**Signature:**

```typescript
export interface AsyncLoggerOptions 
```

## Remarks

Both fields are read independently: pass only `metadata` and the transports still come from `LOGGER_TRANSPORTS`, and vice versa. Passing an empty `transports` array is not the same as omitting it — an empty array means "console only", while omitting it falls back to the environment.

## Properties
