Examples

Limit variable

package main

import (
    "github.com/wiggisser/slidingwindow"
    "fmt"
    "time"
}


func main() {
    //allow 10 requests per 10 seconds
    limit := slidingwindow.NewLimit(10, 10)

    if limit.Check(10) {
        fmt.Println("allowed")
    } else {
        fmt.Println("quota exceeded")
    }

    limit.Reset()

    if limit.Check(10) {
        fmt.Println("allowed")
    } else {
        fmt.Println("quota exceeded")
    }

    time.Sleep(10 * time.Second)

    if limit.Check(10) {
        fmt.Println("allowed")
    } else {
        fmt.Println("quota exceeded")
    }

}

Named Limits

package main

import (
    "github.com/wiggisser/slidingwindow"
    "fmt"
    "time"
}


func main() {
    if e := slidingwindow.NewNamedLimit("limit1", 10, 10); e != nil {
        fmt.Println(e)
    } else {
        fmt.Println("named limit 'limit1' created")
    }

    if b, e := slidingwindow.Check("limit1", 10); e != nil {
        fmt.Println(e);
    } else if b {
        fmt.Println("allowed")
    } else {
        fmt.Println("quota exceeded")
    }
