# GenBatchServer

Elixir wrapper of `rabbitmq/gen-batch-server`

usage:

```elixir

defmodule Stack do

  @moduledoc """

  Example for a very simple-minded Stack server

  """

  use GenBatchServer

  def push(element) do

    GenBatchServer.cast(__MODULE__, {:push, element})

  end

  def pop do

    GenBatchServer.call(__MODULE__, :pop)

  end

  @spec start_link() :: GenBatchServer.on_start()

  def start_link do

    GenBatchServer.start_link(__MODULE__, [:hello], name: __MODULE__)

  end

  @impl GenBatchServer

  def init(stack) do

    {:ok, stack}

  end

  @impl GenBatchServer

  def handle_batch(commands, state) do

    handle_commands([], commands, state)

  end

  # private functions

  defp handle_commands(actions, [], state),

    do: {:ok, actions, state}

  defp handle_commands(actions, [command | rest], state) do

    case command do

      {:cast, {:push, element}} ->

        handle_commands(actions, rest, [element | state])

      {:call, from, :pop} ->

        action = {:reply, from, hd(state)}

        handle_commands([action | actions], rest, tl(state))

    end

  end

end
