Redis中zset的golang實現

zset

初衷是在不用Redis的前提下實現排行榜
項目地址https://github.com/XanthusL/zset

Installation

go get -u github.com/XanthusL/zset

Usage

Removed RWLock in the SortedSet.
Just implement it yourself if you need.

s := zset.New()
// add data
s.Set(66, 1001, "test1")
s.Set(77, 1002, "test2")
s.Set(88, 1003, "test3")
s.Set(100, 1004, "liyiheng")
s.Set(99, 1005, "test4")
s.Set(44, 1006, "test5")
// update data
s.Set(44, 1001, "test1")

// get rank by id
rank, score, extra := s.GetRank(1004, false)
// get data by rank
id, score, extra := s.GetDataByRank(0, true)
// get data by id
dat, ok := s.GetData(1001)

// delete data by id
s.Delete(1001)
