Error Reporting

FastForward Container uses custom exception classes for error handling, all under the FastForward\Container\Exception namespace:

• ContainerException : For general container errors (implements PSR-11 ContainerExceptionInterface )
• NotFoundException : Thrown when a service identifier is not found (implements PSR-11 NotFoundExceptionInterface )
• InvalidArgumentException : For invalid or unsupported arguments
• RuntimeException : For runtime errors, such as non-callable extensions or non-public methods

Example:

use FastForward\Container\Exception\NotFoundException;

try {
    $service = $container->get('unknown');
} catch (NotFoundException $e) {
    // Handle missing service
}
