Golang Dynamic Throttle

In some cases it may be necessary to change the throttle at run time.
The ‘Update’ channel in throttle can be used to provide triggering like time.Ticker.

Installation

$ go get -u github.com/iowar/throttle

Usage

Simple usage example:

package main
import (
        "fmt"
        "time"
        "github.com/iowar/throttle"
)
var (
        kill = make(chan struct{})
)
func main() {
        th := throttle.NewThrottle(time.Second)
        th.Start()
        go func() {
                time.Sleep(time.Second * 6)
                th.ChangeInterval(time.Second * 3)
                fmt.Println("Changing interval.")
        }()
        go func() {
                time.Sleep(time.Second * 15)
                th.Stop()
                fmt.Println("Stopping throttle.")
        }()
        go func() {
                time.Sleep(time.Second * 24)
                th.Start()
                fmt.Println("Starting throttle.")
        }()
        go func() {
                time.Sleep(time.Second * 33)
                kill <- struct{}{}
                fmt.Println("Finish.")
        }()
        go func() {
                for {
                        <-th.Update
                        fmt.Println(time.Now())
                }
        }()
        <-kill
}
