How to type generated Servers

[wackazong]

Sort of a newbie question:

I have multiple services defined via proto files and tonic_build. Works perfectly.

Foo.proto
Bar.proto

Now I have multiple structs in these files (I use the server implementations).

struct FooServer ...
struct BarServer ...

I use them to create the services that I then add to tonic. It's all working beautifully.

What I cannot wrap my head around: how do I define a generic type for these structs so that I can put all of them into one Vec and then add them with one by one with add_service?

Thanks for any pointers.

So add_service doesn't have support for dynamically adding services due to its typed builder nature. One way to get all the services into a vec would be to use an enum that has a type for each one but this won't help you when trying to work with the Server type.
