> I have no idea what you mean here. json.Unmarshal() is an all-or-nothing operation. Are you saying it's common practice to use json.Decoder instead? No, I mean you create a struct that deals with only a part of the JSON, and do multiple calls to Unmarshal. Each struct gets either populated or left at its zero-value depending on what the json looks like. It's useful for parsing json data that has a variable schema depending on what the result was. |
