grpcerrors

Register errors so that they can be safely transmitted over gRPC.

In both client and server:

someError := errors.New("some error")
grpcerrors.Register(1, someError)

In the server:

return nil, grperrors.ToProto(err)

In the client:

_, err := grpcCall()
if grpcerrors.FromProto(err) == someError {
  // ...
}
