# switch-case-spacing

Enforce consistent spacing and break placement in switch cases.

## Targeted pattern scope

This rule inspects each `SwitchCase` body and enforces a specific structure for
non-empty cases.

For non-empty cases, it expects:

- the first consequent statement starts on a later line than `case ...:`; and
- the case ends with `break`, unless the case body starts with a block statement.

## What this rule reports

This rule reports switch case bodies that do not match the expected spacing/break style.

## Why this rule exists

This rule enforces a strict legacy switch layout policy to keep case bodies
visually consistent.

## ❌ Incorrect

```ts
switch (x) {
 case 1:
  foo();
}
```

## ✅ Correct

```ts
switch (x) {
 case 1: {
  foo();
 }
}
```
