Types

type Cache

type Cache struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func New

func New(co *Option) *Cache

func (*Cache) Get

func (cache *Cache) Get(key string) (val any, ok bool)

func (*Cache) GetBytes

func (cache *Cache) GetBytes(key string) []byte

func (*Cache) GetFloat

func (cache *Cache) GetFloat(key string) float64

func (*Cache) GetInt

func (cache *Cache) GetInt(key string) int

func (*Cache) GetString

func (cache *Cache) GetString(key string) string

func (*Cache) Set

func (cache *Cache) Set(key string, val any, expire ...time.Duration)

expire为可选的过期时间，当expire>0时，即便缓存没有满，数据也会因超时被清理

type EvictionPolicy

type EvictionPolicy byte

const (
	PolicyLRU EvictionPolicy = iota
	PolicyLFU
)

type Option

type Option struct {
	Capacity int            //最大缓存数, 默认1024条
	Policy   EvictionPolicy //缓存清理策略，默认LRU
}
