Timers in Go

Timers are important part of any programming languages. They provides async functionality to your applications. We have created a timer that can run 1 million child timers in single timer.

You can create your own timer using tiniyo timer. I am going to add one example of tiniyo timer here:

Example:

package main
import (
	"math/rand"
	"sync"
	timer "github.com/tiniyo/timer"
)
var testTimer timer.TiniyoTimer
type testTimerData struct {
	message string
}
var wg sync.WaitGroup
func testTimerCallbackHandler(data interface{}) error {
	//fmt.Println("testTimerCallbackHandler : ", data.(testTimerData).message)
	wg.Done()
	return nil
}
func main() {
	testTimer.InitializeTiniyoTimer(testTimerCallbackHandler)
	testTimer.Run()
	min := 1
	max := 5
	wg.Add(1)
	for i := 0; i < 1000000; i++ {
		testTimer.StartTimer(uint64(rand.Intn(max-min)+min), string(i), testTimerData{message: "This is test"})
		wg.Add(1)
	}
	wg.Wait()
}

Above code sample creates 1million timers in a range of 1–5 seconds. It waits for it to expire. Once all the timers expire, main exits.
