Types

type Cache

type Cache interface {
	// init cache
	NewCache() error
	// operate method
	// set value
	// if time != 0 set it
	Set(key interface{}, value CacheModel) error
	// get value
	Get(key interface{}) (CacheModel, error)
	// delete value
	Delete(key interface{}) error
	// more del
	// key will become *key*
	DeleteMore(key interface{}) error
	// check value
	// flush the time
	Check(key interface{}) error
	// expire key time
	ExpireKey(key interface{}, seconds int64) bool
}

cache manager

func NewCache

func NewCache(params ...interface{}) (cache Cache)

cache sugar the first param is Cache the second param is confDir

type CacheModel

type CacheModel struct {
	// seconds
	Time int64 `json:"time,omitempty"`
	// data
	Data interface{} `json:"data,omitempty"`
}

data model

func (CacheModel) Struct

func (c CacheModel) Struct(v interface{}) error

Deprecated c.Data to v

func (CacheModel) Unmarshal

func (c CacheModel) Unmarshal(v interface{}) error

Unmarshal support Struct/Array

type RedisManager

type RedisManager struct {
	// do nothing else
	Rc *redis2.ConnPool
}
