This Week in Rust and WebAssembly 006

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.

Did we miss something? Tweet to us at @rustwasm or send us a pull request.
