simple example of how one could wrap their structs for json en/decoding

json_example.go

package main

import (
	"encoding/json"
	"fmt"
)

type blah struct {
	Numbers []int
	Astring string
}

func (self *blah) fromJson(data string) {
	err := json.Unmarshal([]byte(data), self)
	if err != nil {
		fmt.Println("error:", err)
	}
}

func (self *blah) toJson() string {
	data, err := json.Marshal(self)
	if err != nil {
		fmt.Println("error:", err)
	}
	return string(data)
}

func main() {
	ab := `{
		"Numbers": [1, 2, 3],
		"Astring": "this is the string"
	}`

	var ac blah
	ac.fromJson(ab)

	fmt.Println(ac)

	fmt.Println(ac.toJson())
}
