Types

type Cache

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

Cache is an implementation of the cacheme.Backend interface, using LevelDB as its backend to provide persistence.

func New

func (*Cache) Delete

func (l *Cache) Delete(key string) error

Delete removes the given key and its value from the Cache.

func (*Cache) Flush

func (l *Cache) Flush() (e error)

Flush removes ALL key-value-pairs from the Cache.

func (*Cache) Install

func (l *Cache) Install(key, val string, ttl time.Duration) error

Install adds a key-value-pair with the given TTL to the Cache. If the key already exists, it is silently replaced.

func (*Cache) Lookup

func (l *Cache) Lookup(key string) (string, bool, time.Time, error)
