Bytes returns the approximate memory usage of the cache in bytes, including both keys and serialized values.
func (*LRU[K, V]) Get ¶ added in v0.3.1
Get retrieves a value from the cache by its key. Returns the value and a boolean indicating whether the key was found.
func (*LRU[K, V]) Items ¶ added in v0.3.1
Items returns the number of items currently stored in the cache.
func (*LRU[K, V]) Remove ¶ added in v0.3.1
func (c *LRU[K, V]) Remove(key K)
Remove deletes an item from the cache by its key.
func (*LRU[K, V]) RemoveOldest ¶ added in v0.3.1
func (c *LRU[K, V]) RemoveOldest()
RemoveOldest removes the least recently used item from the cache.
