	"context"

	"errors"

	"fmt"

	"time"

	"github.com/Code-Hex/retrygroup"

)

func main() {

	ctx, cancel := context.WithCancel(context.Background())

	g, _ := retrygroup.WithContext(ctx)

	g.EnableBackoff()

	go func() {

		<-time.After(16 * time.Second)

		if cancel != nil {

			fmt.Println("Finish!!")

			cancel()

		}

	}()

	g.RetryGo(3, func(i int) error {

		fmt.Printf("Hello: %d\n", i)

		return errors.New("Try error")

	})

	g.RetryGo(-1, func(i int) error {

		fmt.Println("Never!!")
