Functions

func Delete

func Delete(c *Cache)

Delete New()生成的Cache要Delete()才能彻底删除

func GC

func GC()

GC 清理过期的数据，需要手动调用，比如放到定时任务中 如果数据总量不多，建议懒得GC

Types

type Cache

type Cache struct {
	// contains filtered or unexported fields
}

Cache 缓存

func New

func New() (c *Cache)

New New

func (*Cache) Delete

func (c *Cache) Delete(key interface{})

Delete 删除

func (*Cache) Each

func (c *Cache) Each(f func(k, v interface{}))

Each 遍历

func (*Cache) Exist

func (c *Cache) Exist(key interface{}) bool

Exist 是否存在

func (*Cache) Get

func (c *Cache) Get(key interface{},
	f ...func(key, old interface{}) (v interface{}, t int64)) (v interface{})

Get 取缓存数据，如果不存在或过期就用 f() 创建 t: 有效时间，0永不过期，单位秒

func (*Cache) SetExpire

func (c *Cache) SetExpire(key interface{}, expire int64) bool

SetExpire 设置过期时间戳
