Description

The main scope of this extension is to help PHPStan to detect the type of object after the Assert\Assertion validation.

<?php declare(strict_types = 1);
use Assert\Assertion;

function demo(?int $a) {
	// ...

	Assertion::integer($a);
	// PHPStan is now aware that $a can no longer be `null` at this point

	return ($a === 10);
}
