    Scala wrapper for interacting with AMQP, the aim is for convenient: - scala style usage - RPC calls - event hooks - reconnection strategies - message creation and extraction for common message types

    Overview

    Build connections with io.leonard.amqp.ConnectionHolder.builder

    Create a connection:

    val connection = ConnectionHolder.builder("amqps://guest:password@host:port")
  .eventHooks(EventHooks(eventListener))
  .reconnectionStrategy(ReconnectionStrategy.JavaClientFixedReconnectDelay(1 second))
  .build()

    Create a channel:

    val channel = connection.newChannel()

    Create an RPC server listening on queue "queue.name", expecting a String and echoing it back:

    def rpcHandler(request: Message): Future[Message] = request match {
  case Message.String(string) => Future(Message.String(string))
}
val queue = QueueDeclare(Some("queue.name"))
val rpcServerCloser = channel.rpcServer(queue, AckOnHandled)(rpcHandler)

    Create an RPC client method which sends requests to the queue "queue.name" with a response timeout of 10 seconds :

    val rpcClient = RPCClient(channel)
val rpcMethod = rpcClient.newMethod(Exchange.Default.route("queue.name"), 10 second)

    Create a consumer on "queue.name" printing out strings sent to it:

    def consumer(request: Message): Unit = request match {
  case Message.String(string) => println(string)
}
val queue = QueueDeclare(Some("queue.name"))
channel.addConsumer(queue, consumer)

    Send a message to "queue.name":

    channel.send(Exchange.Default.route("queue.name"), Message.String("message")
