  +### Multiple Arguments
  +
  Rules arguments are one of the most versatile aspects of vee-validate, to drive this point home, let's create a slightly more complex rule. Let's call it `minmax` that will make sure the field value length is between a `min` and a `max`.
  This rule will require two parameters, the first called `min` and the second called `max`, let's define the rule:

  Note how the parameters **must follow** the same order they were defined in.
  :::
  +### Infinite Arguments
  +
  +Some rules accept an infinite number of arguments, consider a `one_of` rule that checks if the specified value in within a defined set, it looks like this:
  +
  +```js
  +import { extend } from 'vee-validate';
  +
  +extend('one_of', (value, values) => {
  + return values.indexOf(value) !== -1;
  +});
  +```
  +
  +For such rules you are not required to define a `params` key, as vee-validate will automatically pass whatever specified in the `ValidationProvider` rules prop to your rule, and it will maintain the same order.
  +
  +```vue
  +<ValidationProvider
  + rules="one_of:1,2,3,4,5,6,7,8,9"
  + v-slot="{ errors }"
  +>
  + <input v-model="value" type="text">
  + <span>{{ errors[0] }}</span>
  +</ValidationProvider>
  +```
  +
  +vee-validate will then pass an array containing: `[1, 2, 3, 4, 5, 6, 7, 8, 9]` to your rule.

  ## Messages
  VeeValidate generates error messages for your fields, the last examples all had this `This field is invalid` message which is the default message configured for all rules, let's take the last examples rules and define messages for them, we can do that by returning strings in the validation function:
