Types ¶

type LRU ¶

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

LRU implements a fixed-size LRU cache with string keys. It can be used concurrently from multiple goroutines.

func NewLRU ¶

func NewLRU(max int) *LRU

NewLRU returns a new LRU that will hold up to max items.

func (*LRU) Get ¶

func (lru *LRU) Get(key string) (val interface{}, ok bool)

Get returns the value associated with key. If the key isn't present in the map, nil and false are returned.

func (*LRU) Set ¶

func (lru *LRU) Set(key string, val interface{})

Set saves a mapping from key to val.

func (*LRU) TestAndSet ¶

func (lru *LRU) TestAndSet(key string, val interface{}, test func(interface{}) bool) bool

TestAndSet saves a mapping from key to val and returns true if key isn't already present or if test returns true when passed the existing value. If test returns false, the mapping is not saved and false is returned. The new mapping is set unconditionally (and true is returned) if test is nil.
