Package errdecode provides a way to represent rules for classifying error values returned by your application.
import "github.com/iamrgon/errdecode"
var ErrInvalidToken = errors.New("invalid token")
var ErrMissingEmail = errors.New("missing email")
var ErrMissingPassword = errors.New("missing password")
func myAppDomainFunc() error {
// Do some work, then return error...
return ErrInvalidToken
}
func main() {
rules := []errdecode.Rule{
{
Code: 1001,
Message: "The provided token is not valid.",
Errors: []error{ErrInvalidToken},
},
{
Code: 1002,
Message: "An email and password is required.",
Errors: []error{ErrMissingEmail, ErrMissingPassword},
},
}
decoder := errdecode.New(rules)
if err := myAppDomainFunc(); err != nil {
log.Fatal(decoder.Translate(err))
}
}Apache
