Если у вас есть зависимости с `yield`, то код выхода (код после `yield`) будет выполняться *после* middleware.

Если были какие‑либо фоновые задачи (рассматриваются в разделе [Фоновые задачи](background-tasks.md), вы увидите это позже), они будут запущены *после* всех middleware.

## Создание middleware { #create-a-middleware }

// channel so that the work function can attempt to exit gracefully.
// Multiple calls to Run will run independently of each other.

	_, err := WithDeadline[struct{}](context.Background(), d.timeout, func(ctx context.Context) (struct{}, error) {

	return err
}

// DeadlineWriter deadline writer with timeout

Se você tiver dependências com `yield`, o código de saída será executado *depois* do middleware.

Se houver alguma tarefa em segundo plano (abordada na seção [Tarefas em segundo plano](background-tasks.md), que você verá mais adiante), ela será executada *depois* de todo o middleware.
