Hello
I have a small test like this
package main
type MError struct {
}
func (m *MError) Error() string {
return "MError"
}
func NewMError() *MError {
return nil
}
func main() {
var e error
e = NewMError()
println(e.Error())
}
I know that interface actually combine like (Type, value), if I change
func (m *MError) Error() string {
to
func (m MError) Error() string {
would lead to "panic: value method main.MError.Error called using nil *MError
pointer",
why we have this different behave?
