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.

WinBtrfs – an open-source btrfs driver for Windows
It's called sans-io in Python land, which is where I heard it first.
https://sans-io.readthedocs.io/
I did it for one of my projects back in 2018 https://github.com/Arnavion/k8s-openapi/commit/9a4fbb718b119...

The bane of my existence: Supporting both async and sync code in Rust
Another option is to implement your API in a sans-io form. Since k8s-openapi was mentioned (albeit for a different reason), I'll point out that its API gave you a request value that you could send using whatever sync or async HTTP client you want to use. It also gave you a corresponding function to parse the response, that you would call with the response bytes however you got them from your client.

(Past tense because I removed all the API features from k8s-openapi after that release, for unrelated reasons.)

Welcome to Comprehensive Rust
Macro expansion is slow, but only noticeably in the specific situation of a) third-party proc macros, b) a debug build, and c) a few thousand invocations of said proc macros. This is because debug builds compile proc macros in debug mode too, so while the macro itself compiles quickly (because it's a debug build), it ends up running slowly (because it's a debug build).
I know this from observing this on a mostly auto-generated crate that had a couple of thousand types with `#[derive(serde::)]` on each. [1]
This doesn't affect most users, because first-party macros like `#[derive(Debug)]` etc are not slow because they're part of rustc and are thus optimized regardless of the profile, and even with third-party macros it is unlikely that they have thousands of invocations. Even if it is* a problem, users can opt in to compiling just the proc macros in release mode. [2]

OpenAPI Generator allows generation of API client libraries from OpenAPI Specs
>OpenAPI Generator allows generation of API client libraries from OpenAPI Specs
It does, but the generated code can be very shitty for some combinations of spec and output language. I maintain Rust bindings for the Kubernetes API server's API, and I chose to write my own code generator instead. The README at https://github.com/Arnavion/k8s-openapi has more details.

Writing a Kubernetes CRD Controller in Rust
As the maintainer of the Rust bindings that the library used in the article (kube) is backed by, I can confirm that Kubernetes' openapi spec requires a lot of Kubernetes-specific handling to generate a good client than generic openapi generators do not provide.
See https://github.com/Arnavion/k8s-openapi/blob/master/README.m... for a full description.
I also confirm that I keep it up-to-date with Kubernetes releases and have been doing so for the ~3 years that it's been around. Not just the minor ones every few months, but even the point ones; these days the latter usually only involves updating the test cases instead of code changes and they're done within a few hours of the upstream release.

What the HAL? The Quest for Finding a Suitable Embedded Rust HAL
Typestate-free HALs: This is in exchange for better ergonomics as the author claims. Only two HALs fall in this category right now which are the STM32-HAL & nRF-HAL.

6 Things I Wish I Knew Starting with Embedded Rust
As I worked with the stm32, as implied earlier, the HALs that I worked with were ones built around embedded-hal traits. Nevertheless, I came across a HAL at a certain point that adopted a different approach that felt more practical and easy to understand. This was the stm32-hal stm32-hal that I found to be more wholesome as it incroporated multiple families of the STM32 under a single HAL umbrella (my original expectation). The STM32-hal eliminates much of the trait confusion that I had encountered before. The thing is the stm32-hal does not seem to be mainstream yet. From what I understand, the HALs built with the mebedded-hal as a basis seem to be the ones mainly adopted by the embedded working group. Additionally, I am not sure if the stm32-hal has any equivalent counterparts for other manufacturer devices.

STM32F4 Embedded Rust at the HAL: GPIO Button Controlled Blinking
📝 At the time of writing this post, it came to my attention that there is an additional HAL that targets STM32 device families (the stm32-hal). From what I figure, right now there seem to be two approaches for developing HALs. The first approach is trait driven so to speak where the embedded-hal is used as a foundation. The second approach is more application-driven and provides a high-level API that targets several families of a device. However, this exists only for the stm32 through the stm32-hal. Right now, the first approach is what I found to be more widespread as it covers different microcontrollers and what this post is based on.

Any frameworks in Rust for developing on SiFive / ST / NXP boards?
For STM32, check out the Peripheral Access Crates by the stm32-rs ream. For higher-level access, I wrote This HAL library for STM32. Works on most newer variants, and includes examples for specific peripherals, and simple applications.
