	Value(key any) (any, bool)
	IsExist(key any) bool
	Clear() bool
	Get(key any) (any, bool)

func OnDiskCache

func OnDiskCache(cachePath string) ICache

func OnGetCache

func OnGetCache(cachename string, persistent ...bool) ICache

初始化一个cache cachename 缓存名字

func OnMemCache

func OnMemCache(cachename string) ICache

type MemCache

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

func New

func New(cleaningInterval time.Duration) *MemCache

New creates a new cache that asynchronously cleans expired entries after the given time passes.

func (*MemCache) Add

func (c *MemCache) Add(key any, value any, lifeSpan time.Duration)

添加一个缓存 lifeSpan:缓存时间，0表示永不超时

func (*MemCache) Clear

func (c *MemCache) Clear() bool

清空表內容

func (*MemCache) Close

func (cache *MemCache) Close()

Close closes the cache and frees up resources.

func (*MemCache) Delete

func (cache *MemCache) Delete(key any)

Delete deletes the key and its value from the cache.

func (*MemCache) Get

func (cache *MemCache) Get(key any) (any, bool)

Get gets the value for the given key.

func (*MemCache) IsExist

func (c *MemCache) IsExist(key any) bool

判断key是否存在

func (*MemCache) Range

func (cache *MemCache) Range(f func(key, value any) bool)

Range calls f sequentially for each key and value present in the cache. If f returns false, range stops the iteration.

func (*MemCache) Set

func (cache *MemCache) Set(key any, value any, duration time.Duration)

Set sets a value for the given key with an expiration duration. If the duration is 0 or less, it will be stored forever.

func (*MemCache) Value

func (c *MemCache) Value(key any) (any, bool)
