Just retries tasks in a time manner.

Install

go get -u github.com/ademozay/re

How It Works

Try, at first, executes given task with no timer started. If an error occurs, it starts a Ticker and a Timer and executes the task every time Ticker ticks unless Timer is finish. If Timer finishes, Try returns the latest error returned from the task.

Usage

This example tries to connect :8000 over tcp 6 times in 3 seconds.

package main

import (
    "net"
    
    "github.com/ademozay/re"
)

func main() {
	var conn net.Conn
    
	err := re.Try(func() error {
		c, err := net.Dial("tcp", ":8000")
		if err != nil {
			return err
		}
		
		conn = c
		return nil
	}, time.Millisecond * 500, time.Second * 3)

	if err != nil {
		log.Fatal(err)
	}
    
    // ...
}
