Types ¶
type Handler ¶
type Handler struct {
// RefreshCallback is called when a syscall.SIGHUP is received.
// If the callback returns an error, the signal handler is stopped. In a
// run.Group environment this means the entire run.Group is requested to
// stop.
RefreshCallback func() error
// contains filtered or unexported fields
}
Handler implements a unix signal handler as run.GroupService.
func (*Handler) ServeContext ¶
ServeContext implements run.ServiceContext and listens for incoming unix signals. If a callback handler was registered it will be executed if a "SIGHUP" is received. If the callback handler returns an error it will exit in error and initiate Group shutdown if used in a run.Group environment.
