The Arch: Using Rust & WebAssembly to animate 30k colored LED lights
In June, Mozilla collaborated with artist Ian Brill to create an installation called the “Arch” at JSConf EU in Berlin. This interactive environment allowed people to experience the intersection of art and technology in a physical, pulsating, immersive way. The environment also created an opportunity for JavaScripters and friends to create animations and experience the underlying capabilities of WebAssembly and Rust.

Baby’s First Rust+WebAssembly module: Say hi to JSConf EU!
A secret project has been brewing for JSConf EU, and this weekend is the big reveal: The Arch is a larger-than-life experience that uses 30,000 colored LEDs to create a canvas for light animations. And you can take charge of this space. Using modules, you can create a light animation. But even though this is JSConf, these animations aren’t just powered by JavaScript modules. In fact, we hope you will try something new… Rust + WebAssembly.

Hello
wasm-pack!Introducing wasm-pack, a new tool for assembling and packaging Rust crates that target WebAssembly. These packages can be published to the npm Registry and used alongside other packages. This means you can use them side-by-side with JS and other packages, and in many kind of applications.

JavaScript to Rust and Back Again: A wasm-bindgen Tale
Recently we’ve seen how WebAssembly is incredibly fast to compile, speeding up JS libraries, and generating even smaller binaries. We’ve even got a high-level plan for better interoperability between the Rust and JavaScript communities, as well as other web programming languages. The goal of wasm-bindgen is to provide a bridge between the types of JavaScript and Rust. It allows JS to call a Rust API with a string, or a Rust function to catch a JS exception. wasm-bindgen erases the impedance mismatch between WebAssembly and JavaScript, ensuring that JavaScript can invoke WebAssembly functions efficiently and without boilerplate, and that WebAssembly can do the same with JavaScript functions.

Making WebAssembly better for Rust & for all languages
To be a useful as a web language, Rust needs to work well with the JavaScript ecosystem. We have some work to do to get there, and fortunately that work will help other languages, too. Lin Clark's code cartoons explore some of the WebAssembly usability challenges that we need to tackle. Want to help?

Where’s Rust headed in 2018? Ask the community.
Rust project leaders are setting the 2018 roadmap based on community input. The priority? Make Rust easier to learn, and make its developers more productive. Expect a major update to the open source systems programming language later this year.

Oxidizing Source Maps with Rust and WebAssembly
A detailed look at how we replaced the most performance-sensitive portions of the
source-mapJavaScript Library’s source map parser with Rust code that is compiled to WebAssembly. The results: The WebAssembly is up to 5.89 times faster than the JavaScript implementation on realistic benchmarks operating on real world source maps! Additionally, performance is also more consistent: relative standard deviations decreased. We hope that, by sharing our experience, we inspire others rewrite performance-sensitive JavaScript in Rust via WebAssembly. -
Hacking & Contributing to Servo On Windows
Like many cross-platform open source projects, Servo, the high-performance browser engine project written in Rust, has always been a bit of a nightmare to build and run on Windows. Luckily, thanks to the Rust team and Servo community, most of the issues have been squashed and we can now launch it with nothing more than […]

Rust and the Future of Systems Programming
If you’re a regular reader of Hacks, you probably know about Rust, the ground-breaking, community-driven systems programming language sponsored by Mozilla. I covered Rust on Hacks back in July, to note a major milestone for Mozilla, when we shipped Rust in Firefox for the first time. Meanwhile in Rust-land, the trains keep on rolling, more […]

Shipping Rust in Firefox
TL;DR: Starting with Firefox 48, Mozilla is shipping its first production Rust code, with more to come! Mozilla ❤ Rust It’s hard to believe it’s been almost seven years since Mozilla Research first began sponsoring the development of Rust, at the time little more than an ambitious research experiment with a small but devoted community.
