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.

Apple is Killing Swift – A great language strangled by governance
The other comment implied it but I think it's worth pointing out that:
> embedded applications that can't have asynchronous execution
Is most definitely not the case.
They can't have the same type of async runtime that would be optimal for a web server or the likes (and I'm not sure all desktop applications and web servers are going to always benefit from the same runtime in the same way), but that's a point in favour of Rust's model imho
If you're interested this is an embedded async runtime that's expected to run in no-std and no-alloc environments

I like the RP2040
If I get your question right, you still need some host software (like a rust compiler)! It's not exactly micropython experience.
The bare minimum would be one of the examples [1] compiled with a Rust compiler and then transformed into a .uf2 file with elf2uf2 [2]. You can then just drag and drop the .uf2 file into the "mass storage device" presented by the bootloader. To get the bootloader to mount, you press a button on a Raspberry Pico (or short two outputs if you're using bare RP2040) while plugging it in.
You'll probably want a debug probe [3] driven by probe-rs [4] at some point, it's just much more convenient to flash and debug with it.

Why choose async/await over threads?
thanks. looked that up. for the curious: https://embassy.dev/

Rust newcomers are 70x less likely to create vulnerabilities than C++ newcomers [pdf]
You should try again. I think that code is verbose because of the borrowing and because you're trying to do a one-liner. I use the nrf-hal library with the nrf52840, and the code reads pretty nicely. Here's an example:

Any good examples of using embedded Rust with an existing embedded C codebase?
Reading nrf-hal source, unfortunately new does re-configure the UARTE, and there is not a new_unchecked. The solution I can think of is to duplicate the write code with nrf52833_hal::pac::UARTE0. The Uarte type does not contain any metadata, it exists purely to guard the init of UARTE.

Really good. Check out the examples in the nrf-hal repo. Also, if you don't mind forking out for some extra components the Knurling sessions by Ferrous Systems are ace.

I rewrote my Rust keyboard firmware in Zig: consistency, mastery, and fun
The embedded HAL crates do this with extensive use of macros, for example: https://github.com/nrf-rs/nrf-hal/blob/aae17943efc24baffe30b...
This solution makes sense given the constraints of Rust, but there's quite a cost in terms of compiler time and cognitive overhead to understand what is going on.
(Aside: I didn't use the HAL in my Rust firmware, that's a higher layer of abstraction; I only used the PAC crates.)
