)

type Person struct {
	ID    int    `json:"id"`
	Name  string `json:"name"`
	Email string `json:"email"`
}

func main() {
	payload := Person{}

	fetch, _ := http.Get("https://jsonplaceholder.typicode.com/users/1")
	msgpack.NewDecoder(fetch.Body).Decode(&payload)
	defer fetch.Body.Close()

	fmt.Println(payload)
