Safety-critical programming

What is Ferrocene?

Ferrocene is the main Rust compiler - rustc - but quality managed and qualified for use in automotive and industrial environments (currently by ISO 26262 and IEC 61508) by Ferrous Systems. It operates as a downstream to the Rust project, further increasing its testing and quality on specific platforms.

Discussions

• A discussion around "Advanced Rust Programming Book Draft"
• Yield/async/continuations etc.,
• What does Rust have instead of garbage collector? - SO
• A decent discussion of Rust vs other PLs on r/rust [Oct 2015].
• What has rust borrowed from Haskell
• rust - How can this instance seemingly outlive its own parameter lifetime? - Stack Overflow

Cargo

• Make your own make -- using Cargo as a general purpose task automation solution.

Installing a package that is not on crates.io: cargo install -f --git https://github.com/cjbassi/ytop ytop

• Cargo Dist distributes your binaries. and in combination with oranda it also generates websites.

Best Practices / Tips

• Perfect Rust Packaging
• spacejam/elements-of-rust: rust style and philosophy

Hardware / bare metal

• Rust bare metal on ARM microcontroller

Rust vs Python

• rochacbruno/py2rs: A quick reference guide for the Pythonista in the process of becoming a Rustacean

Rust and Python

• Making Python 100x faster with less than 100 lines of Rust uses py-spy for profiling; uses maturin to create the project, and pyo3 to create the bindings.

Rust vs Java for rest services

-- via reddit

I gave a talk (video) today about "Rust for Java programmers" at my local java users group. Part of the talk was comparing the implementation of a minimal rest service in a container for the following 4 approaches:

1. Payara-micro (JEE/JAXRS)
2. Wildfly-swarm (another JEE/JAXRS micro deploy)
3. Javaspark (non JEE "lightweight" framework)
4. Rust-rocket

The comparisons are striking, viewed in the same 1/2/3/4 sequence above:

• Container Image Size: 173MB / 151MB / 104MB / 2MB

• Container Startup Time: 22.2s / 17.6s / 1.6s / 0.6s

• Memory Usage at Startup: 630MB / 401MB / 34MB / 1.6MB

• Memory Usage under Stress: 647MB / 522MB / 74MB / 1.7MB

• CPU usage and throughput show a similar progression as above.

Nice job, Rocket! (results are unscientific. fight me) -- Source code

Success Stories

• Rust at OneSignal via

We had a similar challenge supporting sending this many notifications at OneSignal, which we solved using Rust. We recently hit a peak of 850 Million notifications per second, and 5 billion notifications per day. Here's a blog post on how we do it. Written back when we were at "only" 2 billion notifications per week: https://onesignal.com/blog/rust-at-onesignal/

Rolling log of things

2017-09-08:

There is a new book -- Programming Rust by Jim Blandy, and Jason Orendorff. Jim Blandy has also written a concise short book Why Rust [PDF]

Rust is currently unable to call directly into a C++ library; so that way Rust is probably behind D.

• simple event hooks in Rust
• Multithreading in Rust with MPSC (Multi-Producer, Single Consumer) channels
• A web application completely in Rust – Sascha Grunert – Medium
• Rust + actixweb success story July 2018
• My RustConf 2018 Closing Keynote Sept 2018.

Rust, by design, makes certain programming patterns more painful than others. This is a GOOD thing! It turns out that, for game development, the patterns that end up being the easiest to deal with in Rust closely mirror the patterns that are easiest for game development in any language. Rust highly rewards data-oriented design with simple, understandable ownership semantics, and this is great news because this is a really good fit for game development.
