use Rector\Config\RectorConfig;
use Rector\Transform\Rector\String_\StringToClassConstantRector;
use Rector\Transform\ValueObject\StringToClassConstant;

return RectorConfig::configure()
    ->withConfiguredRule(StringToClassConstantRector::class, [
        new StringToClassConstant('compiler.post_dump', 'Yet\AnotherClass', 'CONSTANT'),
    ]);
