Types

type Cache

type Cache struct {
	// Mutex is used for handling the concurrent
	// read/write requests for cache
	sync.Mutex
	// contains filtered or unexported fields
}

Cache holds the required variables to compose an in memory cache system which also provides expiring key mechanism and also maxSize

func NewCache

func NewCache() *Cache

NewCache creates an inmemory cache

func (*Cache) Delete

func (r *Cache) Delete(key string)

Delete deletes a given key if exists

func (*Cache) Exists

func (r *Cache) Exists(key string) bool

Exists returns true if key exists

func (*Cache) Get

func (r *Cache) Get(key string) interface{}

Get returns a value of a given key if it exists

func (*Cache) GetAll

func (r *Cache) GetAll() map[string]interface{}

GetAll returs all the items

func (*Cache) Set

func (r *Cache) Set(key string, value interface{}) bool

Set will persist a value to the cache

func (*Cache) Stats

func (r *Cache) Stats() Stats

Stats get current cache statistics

type Stats

type Stats struct {
	Items int
}

Stats current cache statistics
