Overview

Package errors 封装的错误处理包

使用New创建一个FushinError对象 使用errors.Recover(recover())接收goroutine的recover信息 当Recover一个FushinError时不保留堆栈信息 只记录goroutine id 使用errors.Panic()创建一个带有FushinError的panic

func TestFushinError() {
	defer func() {
		rec := Recover(recover())
		if rec.HasRecover() {
			t.Log(rec.GetTrace())
			t.Log(rec.GID())
		} else {
			t.Log(rec)
		}
	}()
	// 模拟err
	err := New("this is an error")
	t.Log(err.Error())
	// 模拟panic
	Panic("this is a panic")
	// panic
	panic("panic2")
}

Types

type Errors

type Errors interface {
	Error() string
	ID() string
	GetTrace() string
	HasError() bool
	HasRecover() bool
}

type FushinError

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

FushinError 包含goroutineID的可追溯错误

func New

func New(s string) FushinError

func Recover

func Recover(recover interface{}) FushinError

Recover must pass a recover func 当Recover一个FushinError时不保留堆栈信息 只记录goroutine id

func (FushinError) Error

func (f FushinError) Error() string

func (FushinError) GID

func (f FushinError) GID() string

GID 返回recover堆栈的goroutine id

func (FushinError) GetTrace

func (f FushinError) GetTrace() string

GetTrace 获取stack堆栈

func (FushinError) HasError

func (f FushinError) HasError() bool

HasError 是否有错误

func (FushinError) HasRecover

func (f FushinError) HasRecover() bool

func (FushinError) ID

func (f FushinError) ID() string

ID 获取错误的uuid

type TryInstance

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

func Try

func Try(f func()) (ti *TryInstance)

func (*TryInstance) Catch

func (t *TryInstance) Catch(f func(exception interface{})) *TryInstance

Catch Try实例拥有的Catch方法 附带参数exception为出错时包含的错误

func (*TryInstance) Finally

func (t *TryInstance) Finally(f func())

Finally 总是最后运行 Finally中执行的函数未被recover()需要保证不会panic
