+Just yesterday, we submitted our paper [RustBelt: Securing the Foundations of the Rust Programming Language](https://plv.mpi-sws.org/rustbelt/popl18/).
Quoting from the abstract:
> Rust is a new systems programming language that promises to overcome

-This paper is the result of almost two years of work by the [RustBelt](http://plv.mpi-sws.org/rustbelt/) research project to [formalize Rust's type system]({{ site.baseurl }}{% post_url 2015-10-12-formalizing-rust %}).

The paper is now undergoing peer review; some time in fall we will be notified whether the paper got accepted or not.
In case you wondered which "important libraries" we verified, the full list is `Rc`, `Arc`, `Cell` (including [`alias::one`](https://huonw.github.io/alias/alias/fn.one.html), which was recently [accepted into the standard library](https://github.com/rust-lang/rfcs/pull/1789)), `RefCell`, `Mutex`, `RwLock`, `thread::spawn`, `mem::swap`, [`take_mut::take`](https://docs.rs/take_mut/0.1.3/take_mut/fn.take.html) as well as converting `&&T` into `&Box<T>` (inspired by [Abomonation](http://www.frankmcsherry.org/serialization/2015/05/04/unsafe-at-any-speed.html)).
Our model of Rust is somewhat simplified (e.g., we don't support unwinding after panics); still, we were actually able to [find a real bug]({{ site.baseurl }}{% post_url 2017-06-09-mutexguard-sync %}).
For all the details, have a [look at the paper](https://www.mpi-sws.org/~dreyer/papers/rustbelt/paper.pdf).

Of course, I am far from the only person who worked on this.
All these results were only possible because of my great collaborators, [Jacques-Henri Jourdan](https://jhjourdan.mketjh.fr/) and [Robbert Krebbers](http://robbertkrebbers.nl/), as well as my PhD advisor, [Derek Dreyer](http://www.mpi-sws.org/~dreyer/).
I also benefited a lot from countless discussions with the Rust community at large, and with Aaron and Niko in particular.
You guys rock!
