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 does musl make my Rust code so slow? (2020)
That is what Go does. BSDs hate it. https://github.com/redox-os/relibc could be repurposed for this easily enough.

Microsoft rewriting core Windows libraries in Rust
A C standard library rewritten in Rust already exists. [0]
glibc has its share of CVEs, and many of the bugs are of the double free, use-after-free, buffer overflow variety. [1]

Linux libs rewritten in rust?
It is entirely possible to write a libc replacement in Rust. In fact, Redox has done so. There is nothing preventing that library from providing a POSIX interface both to C programs and to the Rust libc FFI crate.
-
How do I use Zig as Rust's Standard C Library?
This is more a Rust question than a Zig question. In Rust, the choice of a specific libc (or to not use a libc) is part of the "target", for example many hardware platforms have gnu/musl/none targets. See also relibc or mustang for pure-rust alternatives. Each libc alternative require some work to integrate into Rust.

Rust Compiler Ambitions for 2022 | Inside Rust Blog
There have been a few attempts to replace libc, at least on Linux - for example Rustix, and Relibc.

Porting Rust's Std to Rustix
There is in fact already a library that does that https://github.com/redox-os/relibc
-
is there a musl implementation in Rust ?
There's relibc.

How hard would it be to port the Rust toolchain to a new non-POSIX OS written in Rust and get it to host its own development? What would that process entail?
Alternatively, there's another initiative called codegen_gcc which is about using GCC as a backend for the rustc compiler. It's (much) more advanced in Rust support, but I am not sure how easy it would be to use a modified libgccjit from there.

"Rust makes me never want to touch C again" -- Matthew Ahrens
In addition to what others have said about platform support, Rust is also on its way to gaining more platform support through rustc_codegen_gcc, the GCC codegen backend for rustc, as an alternative to the LLVM backend. That means many of the platforms GCC supports will suddenly become available with Rust.

Rust contributions for Linux 6.4 are finally merged upstream!
Yeah, rustc_codegen_gcc is a GCC backend for rustc, and its making a lot of good regular progress.

GCC 13 and the State of Gccrs
gcc-rs is one of two projects for bringing Rust to gcc. gcc-rs is the more ambitious of the two, with an entirely new frontend. There is also rustc_codegen_gcc (https://github.com/rust-lang/rustc_codegen_gcc) that keeps the rustc frontend, and only swaps out LLVM for GCC at the codegen stage.

rustc_codegen_gcc: Progress Report #22
Fixing unwinding in release mode is still ungoing. I could use some help here, so anyone with some understanding of unwinding, landing pads or GCC, please come on this issue to discuss this.
-
Any alternate Rust compilers?
Additionally, there is gcc codegen for rustc (https://github.com/rust-lang/rustc_codegen_gcc), which is not a compiler per se, but an alternative code generator, with more architectures supported and other nice things. It's also coming along, but there's still a lot of work to do there too. There's also Cranelift codegen (https://github.com/bjorn3/rustc_codegen_cranelift), which is designed to make debug builds faster, but this is not as exciting/useful as the other 2.

rustc_codegen_gcc: Progress Report #21
Good idea. I added the tag "help wanted" to the issue.

Challenges writing a compiler frontend targeting both LLVM and GCC?
Also, there are indeed ABI issues, e.g. for 128-bit integers and NaN.

A brave new world: building glibc with LLVM
I'm excited about both the backend & the frontend.

Rust front-end merged in GCC trunk
There is also a project for rustc to use GCC instead of LLVM for codegen.
