type Switcher ¶

type Switcher struct {
	Registerer *registerer.Registerer
	// contains filtered or unexported fields
}

Switcher implements the ledswitcher logic. It contains:

1. a Leader that will determine the next LED to switch on, based on the registered endpoints
2. a Registerer that will continuously attempt to register the endpoint with the Leader
3. a Server that will listen for incoming requests, be it registration requests from other endpoints (if leading), or requests from the Leader to switch the LED on/off.

Each Switcher contains all three components. the Configuration's Leader field determines if the switcher is the Leader.
