======

linkio provides an io.Reader and io.Writer that simulate a network connection of a certain speed, e.g. to simulate a mobile connection.

### Quick start

You can use `linkio` to wrap existing io.Reader and io.Writer interfaces:

```go

// Create a new link at 512kbps

link = linkio.NewLink(512 * linkio.KilobitPerSecond)

// Open a connection

conn, err := net.Dial("tcp", "google.com:80")

if err != nil {

  // handle error

}

// Create a link reader/writer

linkReader := link.NewLinkReader(io.Reader(conn))

linkWriter := link.NewLinkWriter(io.Writer(conn))

// Use them as you would normally...

fmt.Fprintf(linkWriter, "GET / HTTP/1.0\r\n\r\n")

status, err := bufio.NewReader(linkReader).ReadString('\n')

```

### History and license

This repository is a fork of [Jeff R. Allen's

linkio](https://github.com/jeffallen/jra-go/tree/master/linkio). linkio

was brought into the world to help make a proxy to simulate slow

Internet links (see [this blog

posting](https://blog.nella.org/a-rate-limiting-http-proxy-in-go/)).
