kani VS MIRAI

Compare kani vs MIRAI and see what are their differences.

MIRAI

Rust mid-level IR Abstract Interpreter (by facebookexperimental)
Nutrient – The #1 PDF SDK Library, trusted by 10K+ developers
Other PDF SDKs promise a lot - then break. Laggy scrolling, poor mobile UX, tons of bugs, and lack of support cost you endless frustrations. Nutrient’s SDK handles billion-page workloads - so you don’t have to debug PDFs. Used by ~1 billion end users in more than 150 different countries.

    Do you use the Cargo "contracts" for Design-by-Contract style invariants that plugs into Facebook's MIRAI prover thing?

    I always thought it this was super neat:

  • Prusti: Static Analyzer for Rust
    8 projects | news.ycombinator.com | 13 Oct 2022
    Here's a 2020 overview of Rust verification tools https://alastairreid.github.io/rust-verification-tools/ - it says

    > Auto-active verification tools

    > While automatic tools focus on things not going wrong, auto-active verification tools help you verify some key properties of your code: data structure invariants, the results of functions, etc. The price that you pay for this extra power is that you may have to assist the tool by adding function contracts (pre/post-conditions for functions), loop invariants, type invariants, etc. to your code.

    > The only auto-active verification tool that I am aware of is Prusti. Prusti is a really interesting tool because it exploits Rust’s unusual type system to help it verify code. Also Prusti has the slickest user interface: a VSCode extension that checks your code as you type it!

    Now, on that list, there is also https://github.com/facebookexperimental/MIRAI that, alongside the crate https://crates.io/crates/contracts (with the mirai_assertion feature enabled) enables writing code like this

  • Kani Rust Verifier – a bit-precise model-checker for Rust
    7 projects | news.ycombinator.com | 23 Mar 2022
    Nice, I just would have liked to get all these different verification tools combined under the same interface, just being different backends as drafted by the rust verification tools work of project oak: have "cargo verify" as common command and use common test annotations, allowing the same test to be verified with different backends or just fuzzed/proptested.

    The model checking approach seems to be a bit limited regarding loops. There are also abstract interpreters, such as https://github.com/facebookexperimental/MIRAI, and symbolic executers, such as https://github.com/dwrensha/seer or https://github.com/GaloisInc/crucible.

    Overall I believe this space would benefit from more coordination and focus on developing something that has the theoretical foundations to cover as many needs as possible and then make a user-friendly tool out of it that is endorsed by the Rust project similar to how Rust analyzer is the one language server to come.

    https://github.com/facebookexperimental/MIRAI which integrates with https://crates.io/crates/contracts (a crate that does runtime checking of contracts, and with mirai they are upgraded to compile-time checking) and https://crates.io/crates/mirai-annotations

    With the mirai_assertions feature, it can use the MIRAI static analyzer (though it requires nightly).
