error.is
should correspond to gerror.Equal
from gf.
err1 := errors.New("permission denied")
fmt.Println(gerror.Is(err1, err1))// false
fmt.Println(gerror.Is(gerror.Wrap(err1, ""), err1))// 这样套一套能返回true,但有点多此一举
func Is(err, target error) bool {
if e, ok := err.(IIs); ok {
return e.Is(target)
}
return false // 这里不应该直接返回
}

对的,同一个错误,Is都返回false,挺反直觉的
