Kani 0.29.0 has been released!
I believe https://github.com/xldenis/creusot is more similar in that it also uses proofs to prove rust code correct.

Prop v0.42 released! Don't panic! The answer is... support for dependent types :)
Wow that sounds really cool! I'm not an expert but does that mean that one day you could implement dependend types or refinement types in Rust as a crate ? I currently only know of tools like: Flux Creusot Kani Prusti

Linus Torvalds: Rust will go into Linux 6.1
Easy reasoning does not end on memory safety. For example, deductive verification of Rust code is possible exactly because there's no reference aliasing in safe Rust

A personal list of Rust grievances
> No support for using something like separation logic within Rust itself to verify that unsafe code upholds the invariants that the safe language expects.
I think this is something we might see in the future. There are a lot of formal methods people who are interested in rust. Creusot in particular is pretty close to doing this - at least for simpler invariants

What it feels like when Rust saves your bacon
You often encounter this entire thread of rhetoric when someone wants to put a diversion into the central argument, yeah but it doesn't ____.
But Rust does do that, match exhaustiveness, forcing the handling of errors and the type system enables things like CreuSAT [1] using creusot [2]

[2] https://github.com/xldenis/creusot
> Creusot works by translating Rust code to WhyML, the verification and specification language of Why3. Users can then leverage the full power of Why3 to (semi)-automatically discharge the verification conditions!
Units of Measure, https://github.com/iliekturtles/uom
The base properties of the language enable things that can never be done in C++.

What Is Rust's Unsafe?
I’m doing my PhD on the formal verification of Rust, and while you’re right that safe code provides a lot of informal advantages it also dramatically simplified form reasoning.
In particular, the dirty secret of C verifiers is that they don’t handle pointers all that well. Either you find yourself doing a lot of manual proof work or you have to dramatically simplify the memory model.
In contrast, when verifying safe Rust, the rules of the borrow checker allow us to dramatically simplify the verification work. All of a sudden verifying a manual memory program with pointers (borrows) becomes as simple as verifying a basic imperative language. I’ve been working on a tool: https://github.com/xldenis/creusot to put this into practice
On the other hand, the moment you dive into unsafe, all bets are off and you find yourself wading through the marshes of (weak) memory models with your favorite CSL as your only friend.
> I’ve been working on a tool: https://github.com/xldenis/creusot to put this into practice
Note that there are other tools trying to deal with formal statements about Rust code. AIUI, Rust developers are working on forming a proper working group for pursuing these issues. We might get a RFC-standardized way of expressing formal/logical conditions about Rust code, which would be a meaningful first step towards supporting proof-carrying code within Rust.

AdaCore and Ferrous Systems Joining Forces to Support Rust
This is exciting! I've met with people from AdaCore and Ferrous systems (individually) several times and they're all serious, competent and motivated.
I'm curious what kinds of software they want to (eventually) verify, my PhD thesis is developing a verification tool for Rust (https://github.com/xldenis/creusot) and I'm always on the look out for case studies to push me forward.
The road to formally verified Rust is still long but in my unbiased opinion looking quite bright, especially compared to other languages like C.

Uncovered Intermediate Topics
An introduction to formal verification in Rust! The whole field is probably is probably too big to cover fully, but an introduction should fit in a single lecture :) Topics that come to mind are Prusti, Cruseot, RustBelt, RustHorn, Stacked Borrows, Miri. These also lend themselves to do follow up topics on.
