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.

Hey Rustaceans! Got a question? Ask here (8/2023)!
It's pretty common to avoid macros as they can seem too magical a lot of the time. And with traits, there's experiments like miniserde which specifically avoid monomorphization overhead. I also see people who want to avoid having lots of dependencies relatively often.

venial 0.1 - A lightweight alternative to syn
Right now, the next step would be to try to reimplement miniserde with venial, and publish benchmarks.

The Serde Rust Framework
The only downside is compile time bloat.
Serde generates heaps and heaps of generic code. This gets optimized away to be very efficient, but it can be quite cumbersome.
Ever tried working on a crate with hundreds or thousands of de/serializable types? Compile times shoot through the roof really quickly.
The maintainer of serde also created `miniserde` [1], which uses dynamic dispatch and can have 4x compile time improvements.
Due to Rusts lack of orphan instances you really depend on a pervasive standard for serializiation which is used by all libraries, so the ecosystem is really locked in to serde by now.

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.

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.
