The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

There have been a few attempts to replace libc, at least on Linux - for example Rustix, and Relibc.

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.

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.

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.
