Exceptions

The package uses focused exceptions so callers can react to invalid input and container lookup failures clearly.

Exception	Thrown when
`FastForward\\Config\\Exception\\InvalidArgumentException`	A method receives invalid input such as an unreadable directory or an invalid `set()` key/value shape.
`FastForward\\Config\\Exception\\ContainerNotFoundException`	`ConfigContainer` cannot resolve the requested identifier.

InvalidArgumentException

Typical scenarios include:

creating DirectoryConfig or RecursiveDirectoryConfig with a directory that does not exist or is not readable;
calling set() with a non-string key while also passing a standalone value.

ContainerNotFoundException

This exception implements Psr\\Container\\NotFoundExceptionInterface and is raised by ConfigContainer when:

the identifier is unknown;
the identifier does not start with config and is not one of the built-in aliases;
config.some.key points to a missing config entry.

Example

use FastForward\Config\Container\ConfigContainer;
use FastForward\Config\Exception\ContainerNotFoundException;
use function FastForward\Config\config;

$container = new ConfigContainer(config(['app.name' => 'Example']));

try {
    $container->get('config.missing.value');
} catch (ContainerNotFoundException $exception) {
    echo $exception->getMessage();
}
