Timeout long-running operations

The previous recipe describes the concept of executing the code with some delay. The same concept can be used to implement the timeout for long running operations. This recipe will illustrate how this can be done.

How to do it...

1. Open the console and create the folder chapter04/recipe11.
2. Navigate to the directory.
3. Create the timeout.go file with the following content:

        package main

        import (
          "fmt"
          "time"
        )

        func main() {

          to := time.After(3 * time.Second)
          list := make([]string, 0)
          done := make(chan bool, 1)

          fmt.Println("Starting to insert items")
          go func() {
            defer...
