4/// NestJS [`DiscoveryService`](https://docs.nestjs.com/fundamentals/discovery-service) analogue:
5/// introspect registered providers and compiled HTTP routes.
6///
7/// Unlike Nest, there is no reflection over arbitrary class metadata: you get [`TypeId`](std::any::TypeId)
8/// keys, type **names** (strings), and whatever is in the global [`RouteRegistry`](crate::RouteRegistry).
9/// Construct with [`Self::new`](DiscoveryService::new)([`ModuleRef`](crate::ModuleRef)).
10///
11/// **Docs:** see the mdBook **Fundamentals** chapter in the `nestrs` repo (`docs/src/fundamentals.md`).
