)

var mymap *xsync.Map[int, []int]

func main() {

mymap = xsync.NewMap[int, []int]()

// キーがなかった場合の挙動

// vはゼロ値

v, ok := mymap.Load(1)

fmt.Println("ok = ", ok)

fmt.Println("v = ", v)

// ok = false

// v = []

// Store

fmt.Println("---")

v = append(v, 1)

v = append(v, 2)

v = append(v, 3)

mymap.Store(1, v)

v, ok = mymap.Load(1)

fmt.Println("ok = ", ok)

fmt.Println("v = ", v)

// ok = true
