Types ¶
type SignalTrap ¶ added in v0.2.45
SignalTrap wraps os.Signal channel to provide high level API above it.
trap := make(chan os.Signal) signal.Notify(trap, os.Interrupt) SignalTrap(trap).Wait(context.Background())
func Termination ¶ added in v0.2.45
func Termination() SignalTrap
Termination returns trap for termination signals.
server := new(http.Server)
go log.Println(server.ListenAndServe())
err := sync.Termination().Wait(context.Background())
if err == sync.ErrSignalTrapped {
log.Println("shutting down the server", server.Shutdown(context.Background()))
}
