Hello Everyone,
I was wondering, what was / is the reason for exposing errors as public
vars - rather than constants? Doesn't that impose some risk?
For example:
fs.ErrNotExist = errors.New("foo")
_, err = os.ReadFile("./invalid")
if !errors.Is(err, fs.ErrNotExist) {
fmt.Println("is NOT fs.ErrNotExist")
}
Would something like the following work (and be less risky)?:
type ConstError string
func (e ConstError) Error() string {
return string(e)
}
const ErrNotExist = ConstError("file does not exist")
Thanks
Seb
