Welcome to a new issue of "This Month in Rust OSDev". In these posts, we give a regular overview of notable changes in the Rust operating system development ecosystem.

This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue or using our comment form at the bottom of this page.

Announcements, News, and Blog Posts

Here we collect news, blog posts, etc. related to OS development in Rust.

• Officially Qualified - Ferrocene
• Edge IoT with Rust on ESP: NTP

Infrastructure and Tooling

In this section, we collect recent updates to rustc, cargo, and other tooling that are relevant to Rust OS development.

There weren't really any OS-related infrastructure updates this month, but there was some great progress on several upcoming language and tooling features that may also be of interest to OS development:

• Stabilize C string literals
• Stabilize ptr::addr_eq
• Feature gate enums in offset_of
