func (*Cache) Decr

func (rc *Cache) Decr(ctx context.Context, key string) error

Decr decrements a key's counter.

func (*Cache) DelMulti

func (rc *Cache) DelMulti(keys []string) error

DelMulti deletes one or more keys from memcache

func (*Cache) Delete

func (rc *Cache) Delete(ctx context.Context, key string) error

Delete deletes a value in memcache.

func (*Cache) Get

func (rc *Cache) Get(ctx context.Context, key string) (interface{}, error)

Get gets a key's value from memcache.

func (*Cache) GetMulti

func (rc *Cache) GetMulti(ctx context.Context, keys []string) ([]interface{}, error)

GetMulti gets one or keys values from ssdb.

func (*Cache) Incr

func (rc *Cache) Incr(ctx context.Context, key string) error

Incr increases a key's counter.

func (*Cache) IsExist

func (rc *Cache) IsExist(ctx context.Context, key string) (bool, error)

IsExist checks if a key exists in memcache.

func (*Cache) Put

func (rc *Cache) Put(ctx context.Context, key string, val interface{}, timeout time.Duration) error

Put puts value into memcache. value: must be of type string

func (*Cache) Scan

func (rc *Cache) Scan(keyStart string, keyEnd string, limit int) ([]string, error)

Scan key all cached in ssdb.

func (*Cache) StartAndGC

func (rc *Cache) StartAndGC(config string) error
