Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Embedded Rust Education: 2023 Reflections & 2024 Visions
Inspired by James Munns's call, and as 2023 is coming to an end, I figure it's a good opportunity to reflect and look forward to 2024. It's been a bit over 1.5 years since I embarked on my embedded Rust journey and it's been nothing less than exciting since. So here it goes.

In search of Rust projects to contribute
Because you are an embedded guy. There is the https://github.com/rust-embedded/wg working-group. Rust on embedded is really on a got track forward. There are many chips/vendors that are supported both in no std / std rust world, but still there is a lot of niche things where you can actively help to be the first to get it run in Rust.

Rust – Are We Game Yet?
To specifically answer your question, here:
* <http://www.areweembeddedyet.com/>
It currently redirects to:
* <https://rust-embedded.org>
Which doesn't really contain anything other than a link to <https://github.com/rust-embedded>.
(via <https://github.com/rust-embedded/wg/issues/15>)

Google announce secure Rust-based OS for embedded system
Then the Rust Embedded workgroup provides: - Direction on how to using generics and zero-sized types to achieve functional safety - svd2rust, which provides safe abstractions to peripheral access from SVD files and achieves this functional safety - The embedded HAL spec, which makes porting to different vendors/hardware easy - Peripheral access controllers and HALs for various vendors & hardware
-
What are your guys' thoughts on Rust?
The Rust Embedded Devices Working Group curates a list of useful embedded Rust resources, including Peripheral Access Crates (autogenerated from SVD files), embedded-hal Implementation Crates (hand-written libraries implementing the traits (interfaces) specified by the embedded-hal), and Board Support Crates.

Question about Rust's binary size
You should also look at https://github.com/rust-embedded/wg/issues/41 and https://github.com/rust-lang/rust/pull/55011#issuecomment-429336055.

Things you can’t do in Rust (and what to do instead)
Here's an interesting discussion, consolidated here. My view is you should use a restricted scope atomic (as best as can be supported) and interact with that through a handler struct. I.e. no global state.
- Semantic Versioning Will Not Save You
- Is there a embedded community/website where it is modern?
-
Would it be possible to run Rust on the new Raspberry Pi Pico?
Most of the issues are explained in EWG RFC 419. The TL;DR is that some resources need to implement Send to be usable from interrupts, but they must not be sent across cores.

The Linux Kernel Prepares for Rust 1.77 Upgrade
This is a good guide on building small Rust binaries: https://github.com/johnthagen/min-sized-rust
This talks about going to extreme lengths on making the smallest Rust binary possible, 400 bytes when it was written, https://darkcoding.net/software/a-very-small-rust-binary-ind...
The thing is, you lose a lot of nice features when you do this, like panic unwinding, debug symbols, stdlib… for kernel and some embedded development it’s definitely important, but for most use cases, does it matter?

Rust wont save us, but its ideas will
Oh it was 137, haha. I will link you to this older comment of mine: https://news.ycombinator.com/item?id=29408906

Making Rust binaries smaller by default
Are you sure? If so then this is awesome news, but I'm a bit confused; the commit in that min-sized-rust repo adding `build-std` to the README was merged in August 2021: https://github.com/johnthagen/min-sized-rust/pull/30
Are you saying that at that point the feature still hadn't "landed in Rust nightly" until recently? If so then what's the difference between a feature just being available in Rust nightly, vs having "landed"?

Was Rust Worth It?
Rust binaries are by default nowhere close to 500MB. If they are not small enough for you, you can try https://github.com/johnthagen/min-sized-rust. By avoiding the formatting machinery and using `panic_immediate_abort` you can get about the size of C binaries.

Tiny Binaries (2021)
That must be without stripping. Also there are ways to reduce binary size. See e.g. [min-sized-rust](https://github.com/johnthagen/min-sized-rust). I've gotten stripped binaries of small cli utils less than 400KiB without doing anything special, less than 150 KiB by customizing profile settings and compressing with upx, and less than 30 KiB by replacing the std with the libc as the link shows. Haven't tried with fltk though...
