> Basic reuseport TCP transport

This package provides a basic transport for automatically (and intelligently) reusing TCP ports.

To use, construct a new `Transport` (the zero value is safe to use) and configure any listeners (`tr.Listen(...)`).

Then, when dialing (`tr.Dial(...)`), the transport will attempt to reuse the ports it's currently listening on, choosing the best one depending on the destination address.


NOTE: Currently, we don't make any attempts to prevent two reusport transports from interfering with each other (reusing each other's ports). However, we reserve the right to fix this in the future.

## Install

`go-reuseport-transport` is a standard Go module which can be installed with:

```sh
go get github.com/libp2p/go-reuseport-transport
```

Note that `go-reuseport-transport` is packaged with Gx, so it is recommended to use Gx to install and use it (see the Usage section).

## Usage

This module is packaged with [Gx](https://github.com/whyrusleeping/gx). In order to use it in your own project it is recommended that you:

```sh
go get -u github.com/whyrusleeping/gx
go get -u github.com/whyrusleeping/gx-go
cd <your-project-repository>
gx init
gx import github.com/libp2p/go-reuseport-transport
gx install --global
gx-go --rewrite
```

Please check [Gx](https://github.com/whyrusleeping/gx) and [Gx-go](https://github.com/whyrusleeping/gx-go) documentation for more information.

This package is *currently* used by the [go-tcp-transport](https://github.com/libp2p/go-tcp-transport) libp2p transport and will likely be used by more libp2p transports in the future.
