Functions ¶
Types ¶
type Handlers ¶
Handlers is map signal → handler
func (Handlers) Track ¶
func (h Handlers) Track()
Track catches signal and executes handler for this signal
Example ¶
hupHandler := func() {
fmt.Println("Got HUP signal")
}
usr1Handler := func() {
fmt.Println("Got USR1 signal")
}
Handlers{
HUP: hupHandler,
USR1: usr1Handler,
}.Track()
Output:
func (Handlers) TrackAsync ¶
func (h Handlers) TrackAsync()
TrackAsync catches signal and executes async handler for this signal
Example ¶
hupHandler := func() {
fmt.Println("Got HUP signal")
}
usr1Handler := func() {
fmt.Println("Got USR1 signal")
}
Handlers{
HUP: hupHandler,
USR1: usr1Handler,
}.TrackAsync()
time.Sleep(time.Hour)
