// Daemon is the interface that contains a set of methods required to be
// implemented in order to be treated as a daemon.
type Daemon interface {
// Startup implementation should...
//
// func (d *DaemonName) Startup() {
// // Set up a panic handler:
// b.HandlePanics(func() {
// log.Error("Oh, crap!")
// })
//
// // If the daemon is also a consumer we need to subscribe for topics
// // that would be consumed by the daemon.
// b.Subscribe("ProductPriceUpdates", func(p PriceUpdate) {
// log.Printf("Price for %q is now $%.2f", p.Product, p.Amount)
// })
//
// // If the daemon is doing some IO it is a good idea to limit the rate
// // of its execution.
// b.SetRateLimit(10, 1 * time.Second)
// }
Startup()
// Shutdown implementation should clean up all daemon related stuff:
// close channels, process the last batch of items, etc.
Shutdown()
// base is a (hack) function that allows the Daemon interface to reference
// underlying BaseDaemon structure.
