Types

type Cache

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

Cache encapsulates a thread-safe fixed size LRU cache as defined in hashicorp/golang-lru.

func New

func New(size int) (*Cache, error)

New returns a new LRU cache that can hold 'size' number of keys at a time.

func (*Cache) Get

func (c *Cache) Get(key string) (interface{}, bool, error)

Get executes a lookup and returns whether a key exists in the cache along with its value.

func (*Cache) Purge

func (c *Cache) Purge() error

Purge evicts all keys present in the cache.

func (*Cache) Remove

func (c *Cache) Remove(key string) error

Remove evicts a specific key from the cache.
