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

Maps a caller-supplied key onto the fully-qualified redis key, applying the prefix the underlying `RedisCache` was initialised with. Bound to that cache, so it is safe to pass around detached.

**Signature:**

```typescript
readonly key: (key: string) => string;
```
