This Week in Rust and WebAssembly 14

Hello and welcome to another issue of This Week in Rust and WebAssembly!

Rust is a systems language pursuing the trifecta: safety, concurrency, and speed.

WebAssembly is a stack-based virtual machine and instruction set. It is fast, safe, portable, and part of the open Web platform. By compiling to WebAssembly, we can run Rust code on the Web!

This is a weekly summary of Rust and WebAssembly’s progress and community.

Working Group Meetings

Gloo

Gloo is the modular toolkit we decided to collectively build in our 2019 roadmap. We’ve been having lots of good discussion about scope and API design in issue threads! (Not doing lots of PRs quite yet.)
@OddCoincidence added support for setInterval to gloo-timers.

`rustwasm.github.io`

@DebugSteven removed some unused CSS rules from our Website’s stylesheets.

`rust-webpack-template`

@alexcrichton upgraded the template to the Rust 2018 edition.

Twiggy

@data-pup upgraded Twiggy to the Rust 2018 edition.
@data-pup added more tests for the twiggy diff subcommand.

`wasm-bindgen`

We released wasm-bindgen version 0.2.39! 🎉
@c410-f3r made wasm-bindgen’s generated TypeScript interfaces’ functions’ argument names be preserved from the Rust source instead of being generated symbols.
@ibaryshnikov cleaned up our Web GL example.
@nstoddard added immutability whitelisting for Uint8Array, ArrayBufferView, and BufferSource.
@RReverser fixed some copy-paste errors in documentation for Int32Array and Uint32Array
@RReverser cleaned up and de-duplicated our binding definitions to the different kinds of typed arrays!
@c410-f3r expanded the testing of our emitted TypeScript interface definitions.
@alexcrichton added the #[wasm_bindgen(raw_module = "...")] attribute to the wasm-bindgen proc-macro.
@konradsz fixed the number-slices example’s JS imports.
@alexlapa enabled passing optional imported enums over the FFI boundary.

`wasm-pack`

We released wasm-pack version 0.7.0! 🎉
@alexcrichton added support for the web target to wasm-pack. This target uses browsers’ native support for ES modules, and doesn’t require the use of a JS bundler.
@alexcrichton started migrating wasm-pack’s CLI output towards our 1.0 vision for wasm-pack output. Notably, cargo build’s colors and progress bar should work now.
@alexcrichton added a smorgasbord of docs improvements.
@drager added support for non-rustup-based Rust development environments to wasm-pack.
@ashleygwilliams added a quickstart doc page for using wasm-pack with Webpack.

`wasm-pack-template`

@alexcrichton upgraded the template to the Rust 2018 edition.
