💼🚫 This rule is enabled in the following configs: `currying`, ☑️ `lite`, ✅ `recommended`, 🔒 `strict`. This rule is _disabled_ in the `disableTypeChecked` config.

💭 This rule requires [type information](https://typescript-eslint.io/linting/typed-linting).

<!-- end auto-generated rule header -->

Disallow use of rest parameters, the `arguments` keyword and enforces that functions take at least 1 parameter.

Note: type information is only required when using the [overrides](#overrides) option.

## Rule Details

In functions, `arguments` is a special variable that is implicitly available.

This option takes a RegExp string or an array of RegExp strings.
It allows for the ability to ignore violations based on a function's name.

### `overrides`

_Using this option requires type infomation._

Allows for applying overrides to the options based on where the function's type is defined.
This can be used to override the settings for types coming from 3rd party libraries.

Note: Only the first matching override will be used.

#### `overrides[n].specifiers`

A specifier, or an array of specifiers to match the function type against.

#### `overrides[n].options`

The options to use when a specifiers matches.

#### `overrides[n].disable`

If true, when a specifier matches, this rule will not be applied to the matching node.
