import (
	"fmt"
	"github.com/nokute78/go-bit/pkg/bit"
)

func main() {
	b := []byte{0x78} /* 0111_1000 in bit */

	/* try to get 4bits(1111b) from 0111_1000 */
	off := bit.Offset{Byte: 0, Bit: 3}

	ret, err := bit.GetBits(b, off, 4)
	if err != nil {
		fmt.Printf("error:%s\n", err)
	}

	fmt.Printf("0x%x\n", ret) /* Print 0x0f = 1111b */
