-
轻量级的缓存字典
-
特色：线程安全、高性能、过期回调、健全的方法
-
PS: 当前仅实现memcache, 后续考虑增加 Leveldb、SSDB、Redis等支持
- go version >= 1.17
package cache
// Reply 缓存器响应内容
type Reply interface {
Has() bool // 是否存在
Val() interface{} // 返回的值
Err() error // 返回的错误
Dur() time.Duration // 剩余时长
Release() // 释放响应结果
}
// Cache 字典缓存器
type Cache interface {
Has(k string) Reply // 是否存在
Set(k string, v interface{}) Reply // 设置键值
SetX(k string, v interface{}, d time.Duration) Reply // 设置键值并设置过期时长
SetN(k string, v interface{}) Reply // 设置键值存在时返回错误
SetNX(k string, v interface{}, d time.Duration) Reply // 设置键值并设置过期时长，如果存在则返回错误
Del(k string) Reply // 删除键值(不存在为成功)
DelExpired(k string) Reply // 删除过期键值(不存在为成功)
Get(k string) Reply // 获取键值
GetDel(k string) Reply // 获取并删除键值
GetSet(k string, v interface{}) Reply // 获取并设置新的键值
GetSetX(k string, v interface{}, d time.Duration) Reply // 获取并设置新的键值和过期时长
Expire(k string, d time.Duration) Reply // 设置新的过期时间
TTL(k string) Reply // 获取过期时间
