這是完整的代碼，與您在 git repo 頁面上找到的代碼沒有太大區別。package mainimport (    "fmt"    "github.com/go-ping"    "time")var stats = [][]string{nil}func pinging(domain string, interval int, unit string, exit int) {current_time:= time.Now().Local()current_time.Format("02-01-2000")switch unit {case "ms":    interval *= 1case "sec":    interval *= 1000case "min":    interval *= 6000}pinger, err := ping.NewPinger(domain)if err != nil {    panic(err)}// interval between pingpinger.Interval=time.Millisecond*time.Duration(interval)//number of total pingspinger.Count=exitpinger.OnRecv = func(pkt *ping.Packet) {    fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v\n",        pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt)}pinger.OnFinish = func(stats *ping.Statistics) {    fmt.Printf("\n--- %s ping statistics ---\n", stats.Addr)    fmt.Printf("%d packets transmitted, %d packets received, %v%% packet loss\n",        stats.PacketsSent, stats.PacketsRecv, stats.PacketLoss)    fmt.Printf("round-trip min/avg/max/stddev = %v/%v/%v/%v\n",        stats.MinRtt, stats.AvgRtt, stats.MaxRtt, stats.StdDevRtt)}fmt.Printf("PING %s (%s):\n", pinger.Addr(), pinger.IPAddr())pinger.Run()}我需要將這些變量 pkt.Nbytes、pkt.IPAddr、pkt.Seq、pkt.Rtt 轉換并附加到一段字符串中，這些變量是來自此 repo https://github.com/sparrc/go-ping的 *net 類型.我需要這樣做，因為之后我會將所有內容打印到 .csv 我該怎么做？
