Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safe, concurrent, and fast. This is a weekly summary of its progress and community. Want something mentioned? Send me an email! Want to get involved? We love contributions.

This was a big week. rvalue lifetimes and external syntax extensions landed, as well as a bunch of codegen optimization.

What's cooking in master?

69 pull requests were merged this week. As of writing, bors has 14 approved pull requests waiting.

Weekly Meeting

The weekly meeting discussed associated function resolution, changes to our calling convention (specifically the fate of the ubiquitous environment pointer), how we want to handle feature freeze, static items with destructors, and documentation on primitives.

Quotes of the Week

{% blockquote tjc on the Rust-the-game/Rust-the-language confusion %} who says you can't make money selling a compiler? You can, as long as you convince people it's a video game

{% blockquote eddyb %} who needs pure functional when you have pure cool?
