func New

func New(maxBytes int) *Cache

New creates new cache with the given maxBytes capacity.

Stop must be called on the returned cache when it is no longer needed.

func (*Cache) Get

func (c *Cache) Get(dst, key []byte) []byte

Get appends the found value for the given key to dst and returns the result.

func (*Cache) GetBig

func (c *Cache) GetBig(dst, key []byte) []byte

GetBig appends the found value for the given key to dst and returns the result.

func (*Cache) Has

func (c *Cache) Has(key []byte) bool

Has verifies whether the cache contains the given key.

func (*Cache) Reset
