func NewLRUExpireCache(maxSize int) *LRUExpireCache

NewLRUExpireCache creates an expiring cache with the given size

func NewLRUExpireCacheWithClock Uses

func NewLRUExpireCacheWithClock(maxSize int, clock Clock) *LRUExpireCache

NewLRUExpireCacheWithClock creates an expiring cache with the given size, using the specified clock to obtain the current time.

func (*LRUExpireCache) Add Uses
