Types

type Cache

type Cache interface {
	//  SetMaxItems sets the maximum number of items the cache can hold to n
	SetMaxItems(n uint)

	// SetMinFreeMemory sets the minimum amount of free memory
	// in bytes before the cache starts evicting objects.
	SetMinFreeMemory(v uint64)

	// SetTimeout sets a default timeout duration for cache items in milliseconds.
	SetTimeout(ms uint)

	// Put stores and pushes the item to the front of the cache.
	Put(k string, v interface{})

	// Get gets the item from the cache and pushes it to the front.
	Get(k string) (interface{}, bool)

	// Del removes the item from the cache.
	Del(k string)

	// Len returns the number of items stored in the cache.
	Len() int

	// Evict removes the oldest n items from the cache.
	Evict(n uint)
