go-error
This package can help define custom error and handle the error gracefully.
- Define custom error.
- Wrap the third party error.
- Wrap context informaton.
- Wrap additional trace information.
- Print statck trace message.
Install
go get github.com/qw20012/go-error
Usage
Define custom error.
func devideByZero(dividend int, divisor int) (int, error) {
if divisor == 0 {
return 0, err.New("Business.DevideByZero", "Given parameter divisor is zero in method devideByZero.")
}
return dividend / divisor, nil
}
Wrap third pary error and relative context information.
func callThirdParty(id int, value int) (int, error) {
r, e := thirdPartyMethod(id, value)
if e != nil {
params := make(map[string]any)
params["id"] = id
params["value"] = value
err.New("ThirdParty.BadArgument", e, params)
}
return r, nil
}
Wrap trace and relative context information.
func callDevideByZero(dividend int, divisor int) (int, error) {
r, e := devideByZero(dividend, divisor)
if e != nil {
return 0, e.(*err.BqError).Wrap("Method callDevideByZero({dividend}, {divisor})").
WithParameter("dividend", dividend).WithParameter("divisor", divisor)
}
return r, nil
}
Check error kind and handle it.
func callAndHandleError() {
_, e := callDevideByZero(2, 0)
if e != nil {
bqError := e.(*err.BqError)
if bqError.Id() == "Business.DevideByZero" {
fmt.Println("second is,: ", bqError)
}
}
}
