Types ¶
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
func (*Controller) Start ¶
func (s *Controller) Start()
means not necessarily starting a single process, but instead that we'll want to keep this subprocess alive. if it dies, it might get restarted automatically, in which case it gets a new pid, new start time etc.
func (*Controller) Status ¶
func (s *Controller) Status() Status
func (*Controller) Stop ¶
func (s *Controller) Stop()
same goes as for start. stop means that we'll want the subprocess to stop (or "pause"). do not call this when you want to gracefully shut down your app, but instead use the stopper mechanism which will automatically tear things down gracefully
