lru-cahce
Golang 内存缓存实现：
- expire 过期剔除
- capacity lru 基于容量的LRU剔除
Example
// new cache instance
c := NewCache(5*time.Minute, 10000)
// easy set
c.Set("key", "value")
// set the value, size and expiration with a key
c.SetEx("key","value", 5, 5*time.Minute)
v, exist := c.Get("key")
if !exist {
// not exist
}
fmt.Printf("Cache hit: %d, cache miss: %d", c.HitNumber(), c.MissNumber())
Performance
