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.

Can I force rust to treat stdlib like other crates in terms of linkage?
I don't know which symbols are missing, haven't done anything on the llvm level. But I had the same problems creating a no-std no-libc application, if you add https://github.com/rust-lang/compiler-builtins as a dependency you should get all the symbols you need, std uses the same but if you want to use it outside of std you'll need nightly since it uses a lot a nightly features. It might apply to your case as well.

[Question] Need help with `avr-hal` for Arduino UNO
Ah, I see - you might be hitting https://github.com/rust-lang/compiler-builtins/issues/347.

Converting Integers to Floats Using Hyperfocus
There's a PR to the compiler-builtins crate which the rust implementation is based on.

rustc + avr = lovelove back again!
I'm glad to inform y'all that after a year, the infamous LLVM ERROR: Not supported instr bug¹ has been finally fixed and today's nightly can compile for AVR back again! 😎

Porting Rust's std to rustix
Then, some of the non-trivial things that are needed are already implemented and maintained in other crates, like memcpy and friends in compiler-builtins, all the math routines in libm and malloc in dlmalloc.

What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?
I found the generics a lot less of a problem when I realized I could parametrize on things like embedded_hal::serial::Write instead of UsartOps https://github.com/Rahix/avr-hal/pull/264/commits/17ed15321cb8fcf8aedb1f8133be1f189eb06a6f

not entirely new to rust, but very new to rust+arduino,.... eli5 the differences between these projects?
I've come across avr-rust, avr-hal and both seem to have arduino stuff, wondering which is the most beginner friendly? (I have a bit of experience with the regular arduino IDE but want to switch over to doing all the stuff in rust for a challenge)

Hey Rustaceans! Got a question? Ask here (1/2023)!
fyi, a minor follow-up at https://github.com/Rahix/avr-hal/issues/388

Rust and arduino?
I have contributed a little to this. avr-hal I have done a couple little hobby projects with it as well, but I can't say it's the best thing out there.

Learning Embedded rust
All you need is in the documentation: https://rahix.github.io/avr-hal/arduino_hal/index.html even though reading the documentation without knowing what you're looking for can be quite difficult, so looking at some examples might be more helpful.

Five simple steps to use any Arduino C++ library in a Rust project 🦀
Rust language shares all advantages of efficient C++ code. With the rust community growing year after year, more and more people try using rust to program their Arduino boards. Consequently, the Arduino Rust ecosystem have significantly developed in the last couple of years. The Hardware Abstraction Layer for AVR microcontrollers avr-hal, Rudino library and ravedude CLI utility to make Rust development for AVR microcontrollers easier are just a few examples of the solid foundation developed so far.

The coincidental typos compiled..
Today I was toying with the arduino again, making an attached LED matrix print awesome messages better than it previously had. I wanted to use millis() found in the examples in the unsurpassed avr-hal crate, to orchestrate the duration it should show (part of) a character before moving on. But that is all besides the point. I made a few mistakes that coincidentally compiled and as such made me believe I was doing things right. (Perhaps I should note here that I am visually impaired so it is a bit easier for me to glance over smaller differences.)

Hey Rustaceans! Got a question? Ask here! (34/2022)!
I'm trying to make an Arduino display text on an LCD using I2C (HD44780). So far, I've used arduino-hal from the avr-hal crate (github.com/Rahix/avr-hal) to program the Arduino, and I wonder if anyone happens to know of a library/crate which is compatible with it? So far I've only found ag-lcd which doesn't seem to work with I2C.
What are some alternatives?
