How to convert Hmget() result to a slice of defined struct?

[piavgh]

Hi @rueian ,

I'm trying to use rueidis to replace go-redis (due to this issue redis/go-redis#2046),
But at the moment, there is no documentation on how to convert a Hmget() result into a slice of defined struct

For example, I want to get the list of pools data by Hmget(), params is the list of pool addresses

cmd := r.redisClient.B().Hmget().Key(r.keyPools).Field(addresses...).Build()
	poolDataList, err := r.redisClient.Do(ctx, cmd).ToArray()
	if err != nil {
		return nil, err
	}

How to convert poolDataList to something like []Pool?
Thanks

Hi @piavgh,

There are two options:

1. Using the .AsStrSlice() instead of the .ToArray() to get a string slice, then you can construct your []Pool from it.
2. Loop over the items of poolDataList and invoke .ToString() on each of them and check nil value by using rueidis.IsRedisNil(err)

Note that if you use .AsStrSlice(), the nil value will be present as an empty string in the string slice.
