  @behaviour Exq.Adapters.Queue
  def enqueue(pid, queue, worker, args, options) do
    {:ok, apply(worker, :perform, args)}

  def enqueue_at(pid, queue, time, worker, args, options) do
    enqueue_somehow(pid, queue, time, worker, args, options)
  end

  def enqueue_in(pid, queue, offset, worker, args, options) do
    enqueue_in_somehow(pid, queue, offset, worker, args, options)
  end
end
