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.

Is rust used for microchip coding?
There's also RTIC which is another framework that makes concurrency trivial.
- Would generators be useful for embedded?
-
RTIC (The hardware accelerated Rust RTOS) releases v2.0.0!
Github here: https://github.com/rtic-rs/rtic

Are there universities that teach Rust?
At Telecom Paris, one of the top engineering schools in France, we teach Rust to undergraduate and graduate students who specialize in Embedded Systems. They get to use Rust and RTIC on STM32 based boards, and they also use Embassy for some projects.
-
When is the right time to change jobs?
If you want something more cutting edge. Try embedded Rust and checkout RTIC. I don't know if it's the real next thing. But i guess it could be fun to try.
-
In which circumstances is C++ better than Rust?
RTIC is still going strong, they are working on a 2.0 release at the moment :). There's also now embassy which provides an async runtime (and a ton of other nice things) for embedded as well :)

My negative views on Rust
That's completely incorrect. The existing ecosystem focuses on web/IO because that's were Async/Await is already being used in other languages so everyone started there. There is significant interest in writing frameworks using async rust in embedded, but the required compiler features for it are still not stable. Check out embassy. Even RTIC has experiments with async.
-
Question: Elegant way of getting a 'static reference?
But neither of them might be usable in you case. Since it looks like you're running bare-metal, a framework like RTIC can give you a initialization function and then pass "static" data to a struct that is shared between all tasks.
-
Is crate Drone already dead? Are there any alternatives? rtfm?
FYI, RTFM has been renamed to RTIC

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...

Shared libraries
This is not quite what you're asking, but it does also address the underlying concern: https://github.com/johnthagen/min-sized-rust
