Elixir-在超时的同时接收和发送消息

Question

我是Elixir的新手，我正在尝试开发向所有其他对等方发送给定数量消息的对等方。此外，在指定的时间之后，节点应停止广播和接收消息。我的问题是如何使其同时发送和接收消息？第二个问题是如何为此设置超时。这是我当前的代码：

messages_sent = Map.new()
messages_received = Map.new()

receive do
  #Distribute messages
  for dest <- peers, do:
    for i <- 0..max_broadcasts, do: #Max broadcast specifies how many messages send to each peer
        send dest, { :peer_broadcast, self()}
        #Adds peer to map or update if it is already present
        Map.update(messages_sent, dest, 0, &(&1 + 1))
    end
  end

 #Receiving messages
  { :peer_broadcast, peer} -> 
       Map.update(messages_received, peer, 0, &(&1 + 1)) 

end #receive
