Redisにおけるzsetのgolang実装

zset
Redisを使わずにランキングアイテムのアドレスを実現するのが目的です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)
