GO-Errors 一个简单易用的golang错误包

说明

本包是可以用来追踪错误链,能够打印出错误的包裹链,对于收集日志,bug调试特别有用

使用方法

import (
    "errors"
    "fmt"
    "testing"
)


var T = New("this is test")

func TestWrap(t *testing.T) {
    var e error
    e = errors.New("Error One")
    e = T.Wrap(e)
    e = e.(*Error).Wrap(e)
    e = Wrap(e)
    e = Wrap(e)
    e = Wrap(e)
    fmt.Printf("%+v\n", e)
    fmt.Printf("%s\n", e.Error())
    
    e2 := New("Error Two")
    e = e.(*Error).Wrap(e2)
    e = Wrap(e)
    e = Wrap(e)
    fmt.Printf("%+v", e)
    fmt.Printf("%s\n", e.Error())
}
