Types ¶
type EvictCallback ¶
type EvictCallback func(key interface{}, value interface{})
EvictCallback is used to get a callback when a cache entry is evicted
type LRU ¶
type LRU struct {
// contains filtered or unexported fields
}
LRU implements a non-thread safe fixed size LRU cache
func New ¶
func New(size int, onEvict EvictCallback) *LRU
NewLRU constructs an LRU of the given size
func (*LRU) Contains ¶
Contains checks if a key is in the cache, without updating the recent-ness or deleting it for being stale.
func (*LRU) Keys ¶
func (c *LRU) Keys() []interface{}
Keys returns a slice of the keys in the cache, from oldest to newest.
func (*LRU) Peek ¶
Peek returns the key value (or undefined if not found) without updating the "recently used"-ness of the key.
func (*LRU) Remove ¶
Remove removes the provided key from the cache, returning if the key was contained.
func (*LRU) RemoveOldest ¶
RemoveOldest removes the oldest item from the cache.
