How do I display the progress bar?

[gouki777]

I don't know how to configure .How do I display the progress bar?
I can't find the relevant documentation

import (
	torrentlogger "github.com/anacrolix/log"
	"github.com/anacrolix/torrent"
	"log"
)
func main() {
	config := torrent.NewDefaultClientConfig()
	config.Logger = torrentlogger.Discard
	config.DownloadRateLimiter
	c, _ := torrent.NewClient(config)
	defer c.Close()
	t, _ := c.AddMagnet("magnet:?xt=urn:btih:xxxxxxxxxxxxxxxxxxxxxx")
	<-t.GotInfo()
	info := t.Info()
	log.Print(info.Name)
	t.DownloadAll()
	c.WaitAll()
	log.Print("OK, torrent downloaded")
}
