Problems with combining built-in tags

[onnttf]

Hello everyone, I would like to ask whether it is currently possible to use built-in tags to complete the verification that something cannot exist and cannot not exist at the same time?

I'm happy to say that I've found a solution using the following code, which uses required_without and excluded_with at the same time.

i := struct {
    User     string `json:"user" validate:"required_without=Role,excluded_with=Role"`
    Role     string `json:"role" validate:"required_without=User,excluded_with=User"`
    Resource string `json:"resource"  validate:"required,uri"`
    Action   string `json:"action"  validate:"required"`
}{}
