Splitting tonic_build code generation into SSR/CSR modules?

[lcmgh]

The default setup as seen here https://github.com/hyperium/tonic/blob/master/tonic-build/README.md creates one large file for the actual grpc Client which includes structs for the request and response types.

I would like to keep my grpc client on the server side but use the response structs on the client-side-rendered web application. Has anyone found a method for doing so? I really don't like to manually duplicate the response structs.

I found that when using

        .build_transport(false)
        .build_client(false)
        .build_server(false)

only entities are created. So what I actually need is to config to define another file in which these entities are put. Then I could annotate them with a feature flag etc.
