maatify / exceptions example snippets

use Maatify\Exceptions\Exception\Validation\InvalidArgumentMaatifyException;

throw new InvalidArgumentMaatifyException('The email format is invalid.');
// Result:
// Category: VALIDATION
// HTTP Status: 400
// Error Code: INVALID_ARGUMENT

use Maatify\Exceptions\Exception\BusinessRule\BusinessRuleMaatifyException;
use Maatify\Exceptions\Exception\System\DatabaseConnectionMaatifyException;

try {
    // Simulate a critical database failure (System / 503)
    throw new DatabaseConnectionMaatifyException('Connection timeout');
} catch (DatabaseConnectionMaatifyException $e) {
    // Attempting to wrap it in a "softer" business exception
    // Note: BusinessRuleMaatifyException is abstract, so we use an anonymous class for this example
    throw new class('Unable to process order', 0, $e) extends BusinessRuleMaatifyException {};
}

// RESULT:
// The final exception will report:
// Category: SYSTEM (Escalated from BusinessRule)
// HTTP Status: 503 (Escalated from 422)
// This ensures monitoring tools see the root cause (System Failure), not a generic Business Rule error.
