<?php

declare(strict_types=1);

namespace App\Workflow;

use Vanta\Integration\Symfony\Temporal\Attribute\AssignWorker;
use Temporal\Workflow\WorkflowInterface;

#[AssignWorker(name: 'worker1')]
#[WorkflowInterface]
final class MoneyTransferWorkflow
{
    #[WorkflowMethod]
    public function transfer(...): \Generator;

    #[SignalMethod]
    function withdraw(): void;

    #[SignalMethod]
    function deposit(): void;
}

Activity example:

<?php

declare(strict_types=1);

namespace App\Workflow;

use Temporal\Activity\ActivityInterface;
use Temporal\Activity\ActivityMethod;

#[AssignWorker(name: 'worker1')]
#[ActivityInterface(...)]
final class MoneyTransferActivity
{
    #[ActivityMethod]
    public function transfer(...): int;

    #[ActivityMethod]
