buntdb 本地db freecache 号称0gc gcache 用的人少 go-cache 实现简单,最快的
ristretto 宣称性能比freecache好,为啥确定存在的值还有命中失败的时候

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 NewLRU ¶
func NewLRU(size int, onEvict EvictCallback) (*LRU, error)
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.
