获取redis golang的队列长度

Question

I am using go-redis package. I fired below query:

rd.LLen("queue_1")

Which returning me below result with type *redis.IntCmd:

llen queue_1: 100001

Count is perfect but I want only count with type of int. Can anyone help?

Answer 1

the LLen func looks like: func (c *cmdable) LLen(key string) *IntCmd

So it returns an IntCmd type. IntCmd provides this function: func (cmd *IntCmd) Val() int64

So you can do e.g.

cmd := rd.LLen("queue_1")
i := cmd.Val() //i will be an int64 type
