ZRANK key member

自2.0.0起可用。

时间严重年夜度: O( log(N))

前往member存储在排序荟萃中的排名,key分数从低到高排序。品级(或指数)是基于0的,这意味着具有最低分数的成员具有品级0

应用 ZREVRANK 取得排序从高到低的元素的排名。

前往值

  • 假定member存在于已排序的荟萃中,则整数回复:排名为member

  • 假定member在有序荟萃key中不存在或不存在,则批量字符串回复:nil

例子

redis>  ZADD myzset 1 "one" (integer) 1 

redis>  ZADD myzset 2 "two" (integer) 1 

redis>  ZADD myzset 3 "three" (integer) 1 

redis>  ZRANK myzset "three" (integer) 2 

redis>  ZRANK myzset "four" (nil)
