Services and Discovery are not generic

[lukos]

Firstly, thanks for this library, it has saved me a lot of time building Envoy's protos. I have an issue though related to the lack of generic support. It seems like the original protos are not correct in Envoy so I am stuck on how to achieve something like the following.

var response = new DiscoveryResponse();
var cluster = new Cluster();

response.Resources.Add(cluster);    // Error, Cannot convert from Cluster to WellKnownTypes.Any

I understand the error, since Resources is defined as RepeatedField whereas Cluster does not inherit from anything. This seems strange since I would expect either that Cluster inherits Any so it can be used in the "Object/Any" repeated field or otherwise, I'm not sure if protobuf supports generics so that DiscoveryResponse in the method e.g. ClusterDiscoveryServiceBase is generic like:

Task<DiscoveryResponse<Cluster>> FetchClusters(DiscoveryRequest request, ServerCallContext context);

So that the repeated field resources is of T rather than Any. Do you know what I am doing wrong here?

I have found Any.Pack(IMessage) but not sure if that is the correct way to do it. It will be a while before I can test my service.
