Bottle up your function calls

Reservoir

With reservoir you are able to bottle up your function calls in an easy way. Make sure your (or other external services) don't become overloaded by time.

Installation

go get github.com/sbani/reservoir

Usage

The example shows us how to print the numbers with a delay.

import (
    "fmt"
    "github.com/sbani/reservoir"
)

func printInt(i int) {
    fmt.Println(i)
}

func main() {
    // Never more than 1 request running at a time.
    // Wait at least 2s between each request.
    limiter := NewReservoir(1, 2 * time.Second)

    for i := 0; i < 5; i++ {
        limiter.add(printInt, i)
    }

    fmt.Println("This is printed first")

    time.Sleep(7 * 2 * time.Second)
}

See reservoir_test.go for informations about usage as long as there are no docs please.

Roadmap
