GetLocalIpToInt本地ip转负数导致panic异常问题

用的一个项目使用了这个包,启动的时候异常了,排查到问题是本地ip可能转换得到负数,除余1023仍然得到负数,然后snowflake约定初始值是0-1023导致panic项目直接启动不了。

// localIp得到负数情况下panic代码 
Node, err = snowflake.NewNode(int64(localIp) % 1023)
if err != nil {
     panic(err)
}

// 雪花算法抛出error逻辑
if n.node < 0 || n.node > n.nodeMax {
    return nil, errors.New("Node number must be between 0 and " + strconv.FormatInt(n.nodeMax, 10))
}

如果确认是负数引起的问题,考虑解决方案

  1. func GetLocalIpToInt() (uint32, error) 参考
  2. 直接在snowflake.NewNode入口处添加localIp转正数的逻辑

请教关于Hub Clients map

go的初学者,有个疑问,能否请教一下
type Hub struct { Clients map[*Client]bool ....

Hub 的Clients key是 *Client类型, value是个bool类型, 我看gorilla websocket chat example也是这样做的, 但是它是没有相关单客户推送的需求. 这是作者实现的单客户推送 是需要循环比对去取*Client,为什么不直接使用 map[int] *Client类型呢, key直接是snowflake产生的id, 还是经过权衡是原方式更有性能优势 ?
