	"github.com/le5le-com/uuid"
)

func main() {
	uuidv7, err := uuid.V7()
	if err != nil {
		panic(err)
	}
	fmt.Printf("UUIDv7: %s, time=%v\n", uuidv7, uuidv7.TimeFromV7())
	// UUIDv7: 0189dd43-c284-7f4f-806e-e7d238e9babb，time=2023-08-10 10:25:52.772 +0800 CST

	s := "0189dd43-c284-7f4f-806e-e7d238e9babb"
	u, err := uuid.Parse(s)
	if err != nil {
		panic(err)
	}
	fmt.Printf("uuid.Parse: %s , %s\n", s, u)

	objectId := "63ede45a8d0137fc1b631091"
	uuidv7, err = uuid.UUIDV7FromObjectID(objectId)
	if err != nil {
		panic(err)
	}
	fmt.Printf("uuid.UUIDV7FromObjectID: %s , %s\n", objectId, uuidv7)

	if uuidv7.ObjectIDHex() != objectId {
		fmt.Printf("Convert uuidv7 to objectId error: uuid.ObjectIDHex=%s, objectId=%s", uuidv7.ObjectIDHex(), objectId)
	}
}
