myEvent := fsm.Event{ Name: "start", Args: map[string]interface{}{ "user": "bob", }, }
fsm := fsm.NewFSM( "closed", fsm.Events{ {Name: "open", Src: []string{"closed"}, Dst: "open"}, {Name: "close", Src: []string{"open"}, Dst: "closed"}, }, fsm.Callbacks{}, ) myEvent := fsm.Event{Name: "open"} err := fsm.Event(myEvent) if err != nil { // error handling }This code sets up a state machine with two states (closed and open) and two events (open and close). Then it triggers an "open" event by creating an Event struct with the Name field set to "open". It uses the fsm.Event() method to pass the event to the state machine and trigger any state transitions that are associated with it. Finally, it handles any errors that might occur. In summary, the go github.com.looplab.fsm library provides a simple but powerful way to create finite state machines in Go. The Event struct is an important component of this library, as it represents the events that trigger state transitions in the machine.
