The Embedded Working Group Newsletter - 13

This is the thirteenth newsletter of the Embedded WG where we highlight new progress, celebrate cool projects, thank the community, and advertise projects that need help!

Discuss on users.rust-lang.org, on twitter, or on reddit!

If you want to mention something in the next newsletter, make sure to leave a comment on the issue.

Highlights

• The min_const_fn feature has landed, allowing for stable use of const fn functions in an embedded context in the upcoming 1.31 release of Rust!
• Frank Pagliughi has kicked off rust-industrial-io, a crate providing an interface to libiio on linux, which is used for communication with industrial sensors and actuators
• gregokent has started development on cortex-r-rt, a runtime crate for Cortex-R processors
• The HAL Impl crate for the Texas Instruments TM4C123 now works on 1.30-beta! Now is a great time to ensure that your embedded crates will work flawlessly with the 2018 Edition of Rust!
