I have this: type Runner interface { TaskName() string Run(ctx context.Context) error }
type Job struct { Tasks []Runner } 1. I have number of structs that implement Runner interface and get added into slice of Tasks. 2. I use json.Encoder to save Job into JSON file. 3. But when I try to load JSON back via json.Decoder I get error: "json: cannot unmarshal object into Go struct field Job.Tasks of type serv.Runner" I guess unmarshaller does not have enough information in saved JSON to restore specific structs. Question: what would be right design decision? Add extra metadata to structs that implement Runner and restore structs manually via type assertion of interface{} during load? Thanks a lot for any help. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
