How to use

The consumer

conn, err := NewConnection("amqp://guest:guest@127.0.0.1:5672/")

if err != nil {
    panic(err)
}

c, err := NewConsumer(conn, false, "events-exchange", "events-queue")

if err != nil {
    panic(err)
}

c.Subscribe("object.*", func(body []byte) bool {
    fmt.Println(body)
    return true
})

go c.Consume()

conn.WaitUntilConnectionClose()

The producer

conn, err := NewConnection("amqp://guest:guest@127.0.0.1:5672/")

if err != nil {
    panic(err)
}

p, err := NewProducer(conn, "events-exchange", "events-queue")

if err != nil {
    panic(err)
}

err = p.Publish("object.my_action", []byte("message"))

if err != nil {
    panic(err)
}
