I am querying NETCONF for Nokia's. The platforms may have different versions, so I did my structs like so:

 pub struct Config {
        pub error: Option<RpcError>,
        pub xconfig: Option<XConfigRpcReply>,
        pub sconfig: Option<SConfigRpcReply>,
    }

    impl Config {
        fn new(error: Option<RpcError>,
               xconfig: Option<XConfigRpcReply>,
               sconfig: Option<SConfigRpcReply>,) -> Config {

            return
                Config {
                    error,
                    xconfig,
                    sconfig,
                }
       }
    }
   #[derive(Debug)]
    pub struct XConfigRpcReply {
        pub config: nokia_ixr_x_config::RpcReply,
    }
    #[derive(Debug)]
    pub struct SConfigRpcReply {
        pub config: nokia_ixr_s_config::RpcReply,
    }

This all works quite well until I have to get the data out of these. Do I have an XConfig or SConfig? Trying to match doesn't seem to work because match takes the first arm as the expected type and the second arm becomes a mismatched type.

I am wondering how to solve this. Would a Traits with for the two Config types do it?
