Package: @imqueue/rpc 3.5.3 — generated reference, not hand-written

The self-description a service serves to its clients, and the input to client generation.

**Signature:**

```typescript
export declare class Description 
```

## Remarks

Declared as a class for historical reasons but never instantiated: a service returns a plain object literal, and a client receives its JSON round-trip. So do not use `new Description()` or `instanceof Description`.

A service memoizes its description after the first request for it.
