type RedisOpts 

type RedisOpts redis.UniversalOptions

RedisOpts is the overriden type of redis.UniversalOptions. simple() and cluster() functions are not public in redis library. Therefore, they are redefined in here to use in creation of new redis cluster logic. We don't want to use redis.NewUniversalClient() logic.
