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.

Maestro: A Linux-compatible kernel in Rust
One of the inspirations for Rust, as I recall, was Cyclone: https://cyclone.thelanguage.org/
Which was/is a "safe" dialect of C; basically C extended with a bunch of the stuff that made it into Rust (algebraic datatypes, pattern matching, etc.) Though its model of safety is not the borrow checker model that Rust has.
Always felt to me like something like Cyclone would be the natural direction for OS development to head in, as it fits better with existing codebases and skillsets.
In any case, I'm happy to see this stuff happening in Rust.

C for All
It sounds like they re-invented Cyclone.

Is it possible to have a superset of the C programming languages standard that is as safe as Rust?
Looks like it was a research project and is now abandoned: http://cyclone.thelanguage.org

Need to learn FAST... Any recommendations for a free interactive rust course?
The borrow checker is Rust's secret sauce. It's the one thing no other language has. (Except Cyclone I think, which is an unmaintained research language.)
- What do you think about a C transpiler?

Is my method of programming wrong?
Also, lifetimes are not the mechanism by which Rust ensures safety - it's a necessary side-effect of the approach that Rust has taken, and this has nothing to do with the issues that "plague" other languages. Region-based memory management techniques are neither new nor really innovative. https://cyclone.thelanguage.org/, which directly inspired Rust, had them, and the authors gave up working on it because the ergonomics were terrible, as is the case with Rust. Lifetimes are needed for the Rust compiler to reason about what it can reasonably allow at compile time, but it, along with the Borrow Checker (which provides the actual safety net) ensures that whole swathes of valid programs are disallowed because the Rust compiler is not smart enough (and probably never will be) to check that these programs are valid.

The Fil-C Manifesto: Garbage In, Memory Safety Out

Also, one can combine subsets of C with FOSS, static analyzers that can handle those subsets. Then, compose only in ways that the tools can handle. Then, combinatorial and fuzz testing of the interface composition.
I know you’re doing the project for fun while exploring specific ways to achieve your goals. So, these are just some links and concepts that might help on your journey. Lots of folks don’t know about prior work in this area. So, I keep passing it on.

Azure CTO: “It's time to halt starting any new projects in C/C++ ”
Yes. Microsoft Research is working on "Checked C": https://www.microsoft.com/en-us/research/project/checked-c/
As a test, someone ported FreeBSD's networking stack to Checked C. It was easy and there was no overhead to performance and binary size.

I want to learn csharp man
Haha. I think they did ultimately agree. Thus a later research project is: Checked-C
What are some alternatives?
cyclonic - WIP port of cyclone to modern platforms
koka - Koka language compiler and interpreter
cedro - C programming language extension: Cedro pre-processor
rust.ko - A minimal Linux kernel module written in rust.
cake - Cake a C23 front end and transpiler written in C
manyclangs - Repository hosting unofficial binary pack files for many commits of LLVM
cyclone
c2rust - Migrate C code to Rust
BorrowScript - TypeScript with a Borrow Checker. Multi-threaded, Tiny binaries. No GC. Easy to write.
linux - Linux kernel source tree
checkedc-clang - This repo contains a version of clang that is being modified to support Checked C. Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe.
