Types

type LRUCache 

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

LRUCache provides a simple LRU cache with both size and TTL limits. It uses RWMutex for optimal concurrent access patterns - multiple concurrent reads are allowed while writes get exclusive access.

func NewLRUCache 

func NewLRUCache(maxSize int, ttl time.Duration) *LRUCache

NewLRUCache creates a new LRU cache with the specified maximum size and TTL.

func (*LRUCache) Add 

func (c *LRUCache) Add(key string)

Add marks a key as cached. This operation uses a write lock for exclusive access. If the key already exists, its expiration time is updated and it's moved to the end of the LRU order. If the cache exceeds maxSize, oldest entries are evicted.

func (*LRUCache) Clear 

func (c *LRUCache) Clear()

Clear removes all entries from the cache.

func (*LRUCache) Delete 

func (c *LRUCache) Delete(key string)

Delete removes a key from the cache.

func (*LRUCache) Has 

func (c *LRUCache) Has(key string) bool

Has checks if key exists and hasn't expired. This operation uses a read lock, allowing concurrent access.

func (*LRUCache) Size 

func (c *LRUCache) Size() int

Size returns the current number of entries in the cache.
