    if err != nil {
      fmt.Println(err)
    }

    // or
    desiredLen := 64
    your64CharLongID, err := randid.SizedID(desiredLen)
    // -> 6cc77090ff64c232613574bb562510f78d88a84e8351f3a68ac1caa902750bb7

      fmt.Println(err)
    }

    // change randid default len
    // every id generated from now on with .ID() will be 33 char long
    randid.DefaultLen = 33

    your33CharLongID, err := randid.ID()
    // -> 091015d5146b6d2e3f77ff50d805cee50
