Types

type State

type State func() State

State is used to implement a lightweight state machine. Each state is represented by a closure, that, when run, returns the next state (or nil to stop the machine).

func (*State) Update

func (s *State) Update()

Update runs s (i.e. the current state), and replaces it with the result of that call. It's safe to call Update on a nil target.
