支持完整的逻辑条件

[devhaozi]

比如有一个结构体字段IP，想验证它是IP地址或者CIDR表示，但是验证IP和验证CIDR都是独立的规则。

如果写validate:"ip|CIDR"的话，是逻辑与，要求两个规则都满足，希望能实现完整的逻辑条件（或和非），这样可以用逻辑或实现上面的验证。

在 https://github.com/go-playground/validator 中，逗号用于逻辑与，竖线用于逻辑或。

The validate library already uses | as the rule separator, so it can't be reused to represent logical OR. To support logical OR between rules, it would be a good idea to introduce a new built-in validation rule, such as one_of, which can combine multiple rules and pass if any of them are satisfied. For example, validate:"one_of:ip CIDR" would mean the field is valid if it matches either the IP or the CIDR rule.
