ok, I think I understand how this library works, and posting this for future reference in case someone needs it.
The library uses this other library: https://github.com/mitchellh/mapstructure So now I can do this and vim go will helpfully fill in the struct fields for me. client := foreman.Client("foreman.l.example.org", "admin", "whatever", false, "") resp, err := client.Get("hosts") if err != nil { fmt.Println(err) } var host foreman.Host err = mapstructure.Decode(resp, &host) if err != nil { fmt.Println(err) } fmt.Println(host.Capabilities...)
