package time
Golang time.Time.NewTimer(), Stop() functions and time.Timer type usage example.
package main
import (
"fmt"
"time"
)
func main() {
duration := time.Duration(5) * time.Second
timer := time.NewTimer(duration)
go func() {
<-timer.C
fmt.Println("Timer expired")
}()
time.Sleep(time.Duration(3) * time.Second)
stop := timer.Stop()
fmt.Println("Timer stopped before expired : ", stop)
}
Output :
Timer stopped before expired : true
If you increase the time.Sleep duration to above 5 seconds. The timer will be stopped before expiring.
package main
import (
"fmt"
"time"
)
func main() {
duration := time.Duration(5) * time.Second
timer := time.NewTimer(duration)
go func() {
<-timer.C
fmt.Println("Timer expired")
}()
time.Sleep(time.Duration(6) * time.Second)
stop := timer.Stop()
fmt.Println("Timer stopped before expired : ", stop)
}
Output :
Timer expired
Timer stopped before expired : false
