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.

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

Accessing the Pinecil UART with Picoprobe
Running the Embassy RP2040 USB CDC ACM serial example takes about 5 seconds on a Pico.

Avoid Async Rust at All Cost
Async solves different problems, you can, for instance, have just a single-threaded CPU and still have a nice API if you have async-await. It might not be so cool at a higher level as Go's approach of channels and threads, but it's cool in embedded, read this:
https://github.com/embassy-rs/embassy?tab=readme-ov-file#rus...
"Rust's async/await allows for unprecedently easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation, and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!"
I'm just toying with Raspberry Pi Pico and it's pretty nice.
Go and Rust have different use cases, the async-await is nice at a low level.

Is anyone using coroutines seriously?
I have not yet dipped by toes in the Rust waters, but reading about the embassy project is actually what piqued my curiosity about using C++ coroutines in embedded. Are you familiar with the project or have you found it lacking?

The state of BLE and Rust (no_std)
I think I get the basics (shoutout to the Rust Embedded Working Group!), and I've started looking for the stack I'd be using. I think Embassy is really amazing, as well as the work of the ESP team -- hats off.

And this is how to do it using embassy, which is an async framework for embedded in rust:

The State of Async Rust
> not good for embedded
embassy begs to differ
https://embassy.dev/
async/await is really just a syntax for building state machines in a way that resembles regular code. It's compiled down to the same code that you would write by hand anyway (early on it had some bloat in state size but I think it's all fixed now).
And embedded has a lot of state machines!

Asynchronous Rust on Cortex-M Microcontrollers
You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com/embassy-rs/embassy/blob/main/examples/nrf...

Implementing TCP in Rust
There is also the Rust TCP/IP stack https://github.com/smoltcp-rs/smoltcp which is not mentioned as reference (and it's probably more useful to have a look there than querying ChatGPT).
- RFC2217 implementation written in Rust

Create TCP connection with Pnet
Trying to dig out a link for you, will edit when I find it; TCP and Layer 4 raw sockets do not play nicely together on many platforms. You’ll probably have to send at the datalink layer and/or use something like https://github.com/smoltcp-rs/smoltcp

Introduction to TCP and Sockets
This seems close to what you're asking for: https://github.com/smoltcp-rs/smoltcp
A small-ish tcp/ip stack, in rust.
- smoltcp is a standalone, event-driven TCP/IP stack that is designed for bare-metal, real-time systems. Its design goals are simplicity and robustness.

Kerla: Monolithic kernel in Rust, aiming for Linux ABI compatibility
This here is a kernel including a memory-safe TCP/IP stack (https://github.com/smoltcp-rs/smoltcp/), and not having it crash or be full of security vulnerabilities due to preventable memory corruption is a quality beyond personal language preferences.

Let's suppose for a minute that I've COMPLETELY lost my mind
Oh, and you also probably want to check out smoltcp, a userspace/"no operating system required" networking stack that we often use in embedded rust.
