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.

Rust on Espressif chips – 29-09-2023
In the esp-hal, they appear to offer both sync and async I2C implementations, depending on what works best for an application. Since the async implementation is gated by a feature, it may not show up in the docs you linked.
Async implementation: https://github.com/esp-rs/esp-hal/blob/main/esp-hal-common/s...
You can also see the async feature mentioned here: https://docs.rs/crate/esp32s2-hal/latest/features

The Embedded Rust ESP Development Ecosystem
Going another level up the chain, we then have the hardware abstraction layer (HAL) crate. HAL crates are supposed to offer more portability and user-friendly API for a particular processor. For ESP devices the different hals are captured in the esp-hal repository. This occurs by implementing some common traits defined in what is referred to as the embedded-hal. Additionally, the device HAL attempts to incorporate mechanisms, or wrappers around lower-level functions, that are part of the Rust safety model.

How to write HALs and get into microcontroller programming
There is https://docs.rust-embedded.org/book/design-patterns/hal/index.html but I wonder what OP is missing in https://github.com/esp-rs/esp-hal

Rust in Automotive
It’s definitely used for “nonsafety” stuff like infotainment. The ATSAMD HAL/PACs are probably the most complete embedded microcontroller family as far as Rust support goes, and that’s a part with heavy intent toward automotive use.

Looking for a highly resource constrained target to run Rust on. Any ideas?
The Rust ATSAMD community has been very helpful getting me going. I've really become fond of RTIC as a way to get a little structure in my programs.
- Code Rust in Aurdino??

Are there any ways to use rust for the Arduino MKR WiFi 1010?
The atsamd-rs rust folks (https://github.com/atsamd-rs/atsamd) have made this way easier! Check out my top level comment!

Hello, Microcontroller! Intro to video codecs and the "hello, world" of microcontrollers implemented in ~100 lines of dependency-free Rust
I'm obviously biased, but as a starting point I would recommend getting an Arduino and following the process in the article. Once you have a blinking LED, try it again using a HAL like atsamd-rs/atsamd. Then try making it more complex: configure the clock and replace the delay implementation with something that takes a proper duration argument, add serial IO via the USB port so you can communicate with your program as it runs, connect some more LEDs or buttons and interact with them, or make some network requests.

Want to Learn Programming and Microcontrollers?
Am admittedly too inexperienced to properly weigh the pros and cons of various platforms, but I find the Rust support for certain embedded platforms to be particularly compelling.
https://github.com/atsamd-rs/atsamd
I have at least managed to get some literal blinkenlights doing what I want on various Adafruit boards with very little effort.
- I’d like to learn rust to make a USB device that enumerates as a mouse to the OS and shakes the pointer every once in a while. I’m a web developer by trade. How realistic is this project?
