# Worked extension examples

These developer-facing recipes are kept beside the package contract. Replace the example values with the site-specific records and data objects used by the calling workflow.

<!-- example: contract Capell\ThemeSwitchboard\Contracts\PublicIndexProvider -->

```php
<?php
declare(strict_types=1);
final class ExamplePublicIndexProviderImplementation implements \Capell\ThemeSwitchboard\Contracts\PublicIndexProvider
{
    /** @return list<SwitchboardIndexItemData> */
    public function items(): array
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\ThemeSwitchboard\Contracts\PublicIndexProvider::class, ExamplePublicIndexProviderImplementation::class);
```
