Rust has been through a lot of changes in recent years. As such, tutorials get out of date. We’ve occasionally said that including rustc -v in your blog posts would be helpful, but today, I saw this tweet go by:

After some quick hacking, I’ve modified it to work with Rust. You can find the project here: https://github.com/steveklabnik/rust-community-versions

TL;DR: Put this into your blog post, substituting the appropriate date and title:

<iframe width="178" height="24" style="border:0px" src="http://steveklabnik.github.io/rust-community-versions/2013/10/18/pointers-in-rust-a-guide.html"> </iframe>

Then, make a pull request adding a new post with some front-matter:

--- layout: post url: http://words.steveklabnik.com/pointers-in-rust-a-guide title: "Pointers in Rust: a Guide" date: 2013-10-18 start_version: 0.8 end_version: 0.9 ---

( end_version is optional)

And bam! You get a nice looking badge. Check out out on this blog post of mine: http://words.steveklabnik.com/pointers-in-rust-a-guide

What’s nice about this approach is that, if your post ever gets out of date, someone else can modify the YAML in the repo, and your badge will automatically update to include the end date. No remembering to go back and fix it.

Let’s see how this goes!
