```

## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go theme={null}
switch chatRequestStop.Type {
	case components.ChatRequestStopTypeStr:
		// chatRequestStop.Str is populated
	case components.ChatRequestStopTypeArrayOfStr:
		// chatRequestStop.ArrayOfStr is populated
}
```
