	"time"

	"github.com/yudppp/throttle"

)

func main() {

	throttler := throttle.New(time.Second)

	throttler.Do(func() {

		fmt.Println("first call")

	})

	throttler.Do(func() {

		// this function called never.

		fmt.Println("second call")

	})

	time.Sleep(time.Second)

	throttler.Do(func() {

		fmt.Println("third call")

	})

	time.Sleep(time.Second)

}

	var wg sync.WaitGroup

	for i := 0; i < 64; i++ {

		wg.Add(1)
