	"github.com/satori/go.uuid"
)

func main() {
	// Creating UUID Version 4
	// panic on error
	u1 := uuid.Must(uuid.NewV4())
	fmt.Printf("UUIDv4: %s\n", u1)

	// or error handling
	u2, err := uuid.NewV4()
	if err != nil {
		fmt.Printf("Something went wrong: %s", err)
		return
	}
	fmt.Printf("UUIDv4: %s\n", u2)

	// Parsing UUID from string input
	u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
