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.

Liblithium: A lightweight and portable cryptography library
I'm latching onto a non-main argument to be pedantic, but I'd like to mention that Rust is fine for _non-embedded_ kernel development too, in my experience.
As you're likely aware, Rust for embedded sucks when there's no HAL, but should be very pleasant otherwise. Have you looked into the cortex-a[1] crate?
Some unnecessary instructions could also be a part of an ongoing optimization effort[2][3].

Rust OS cortex a5
It looks like you can. I have no experience with this but you can also check out the rust channel of the embedded engineers discord for help if you hit a snag.

A toy std::fs impl that does not need libc
I made a toy std::fs implementation that does not depend on libc, i.e., using Raw Syscall. There are some voices in the community stating that we should make the standard library opt out of libc for better performance, so I decided to give it a try and wanna know if I could impl such stuff by myself.

Single syscall "Hello, world" - in Rust - part 2
Rust is not JavaScript, but there actually is a crate for that. Let's add it to our Cargo.toml:
What are some alternatives?
cortex-m-quickstart - Template to develop bare metal applications for Cortex-M microcontrollers
fs - A toy std::fs implementation that does NOT depend on libc
scapegoat - Safe, fallible, embedded-friendly ordered set/map via a scapegoat tree. Validated against BTreeSet/BTreeMap.
cross - “Zero setup” cross compilation and “cross testing” of Rust crates
cortex-m - Low level access to Cortex-M processors
cross - “Zero setup” cross compilation and “cross testing” of Rust crates [Moved to: https://github.com/cross-rs/cross]
liblithium - A lightweight and portable cryptography library.
udbserver - Unicorn Emulator Debug Server - Written in Rust, with bindings for C, Go, Java and Python
cortex-m-rt - Minimal startup / runtime for Cortex-M microcontrollers
gpoint - Rust wrapper for using libc's `printf("%g")` format for your floating point output
rtic - Real-Time Interrupt-driven Concurrency (RTIC) framework for ARM Cortex-M microcontrollers
xargo - The sysroot manager that lets you build and customize `std`
