Functions

func CheckAndCreateFile

func CheckAndCreateFile(filePath string, flag int, perm os.FileMode) (*os.File, error)

func Env

func Env() string

func GetValueOnEnv

func GetValueOnEnv(prod, test interface{}) interface{}

func Int64Ptr

func Int64Ptr(v int64) *int64

func IsTest

func IsTest() bool

func MaxInt64

func MaxInt64(a, b int64) int64

func MinInt64

func MinInt64(a, b int64) int64

Types

type Lru

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

func NewLRU

func NewLRU(size int) *Lru

func (*Lru) Read

func (lru *Lru) Read(key interface{}) interface{}

func (*Lru) Remove

func (lru *Lru) Remove(key interface{}) interface{}

func (*Lru) Traverse

func (lru *Lru) Traverse(do func(item interface{}) error, skipErr bool) error

Traverse 遍历lru中的存储元素，对每个元素执行do方法 如果执行do方法过程中出现错误，Traverse 会根据 skipErr 决定是否忽略错误，即当 skipErr 为true时，Traverse 不会返回错误 当 skipErr 为false时，Traverse 会返回第一个出现的错误

func (*Lru) Write

func (lru *Lru) Write(key, data interface{}) interface{}

todo：lock性能

type UnboundChan

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

func NewUnboundChan

func NewUnboundChan() *UnboundChan

func (*UnboundChan) Close

func (uc *UnboundChan) Close()

func (*UnboundChan) In

func (uc *UnboundChan) In()

func (*UnboundChan) Len

func (uc *UnboundChan) Len() int64

func (*UnboundChan) Out

func (uc *UnboundChan) Out() bool
