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.

Compiling Linux to Mac in CI/CD
Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.
- Hey Rustaceans! Got a question? Ask here (13/2023)!

Does anyone have resources on cross-compiling windows to mac?
Your target is not directly supported (licensing issues I presume), but there seems to be a way to create your own image and then use it. It's worth a try.

Cross v0.2.2 Released
A lot of work has been spent making the process as painless as possible. A crosstool-ng image is slightly more complex, but still quite easy: you just need a valid config file. The basic logic can be found here, and cross-toolchains has a few more examples.

Show HN: macOS-cross-compiler – Compile binaries for macOS on Linux
https://github.com/rust-cross/cargo-zigbuild
I’m curious what the blockers are for rustc to cross-compile like zig does natively.
- Cargo-zigbuild: Compile Rust using Zig as linker for easier cross compiling
- [Review] Introducing cargo-xwin: A Solution for Cross-Compiling Rust on macOS to MSVC
- Compiling Linux to Mac in CI/CD
- cargo-zigbuild 0.16 added support for (cross-)compiling macOS universal2 binaries/libraries
-
Conditional compilation to avoid cross compilation
Perhaps you can try cargo-zigbuild, it uses zig-cc for cross-compilation instead of creating a container, so it should be much more lightweight on MacOS, without all the cost of virtualization and file sharing.

Future of Rust, 2023 and beyond?
I have tried, however I haven't been able to get it to work reliably (e.g. building on windows + linux on WSL works, Mac is a lot more involved; tried building for windows + linux on Mac and I couldn't get it to work at all); I've had some luck using zigbuild but that too doesn't seem to work for Mac.

C2Rust Transpiler
Zig also takes this approach, and even exposes its C compiler (which if I recall correctly is basically Clang plus diverse sysroots and other customisation out of the box) as a separate `zig cc`.
I do a lot of work in Rust, and cross-compilation can be a pain when you have a lot of C dependencies. Fortunately https://github.com/messense/cargo-zigbuild exists. It sounds crazy, but using Zig's inbuilt C compiler to help build my Rust projects has been the smoothest option I've found.
I can't help but wonder if it would be worth it for Rust to follow D and Zig by shipping its own inbuilt C compiler, even if they still want to also support external C toolchains. It should be roughly the same effort as it was for Zig, given that they both use LLVM.

Short story of Rust being amazing yet again (because it compiles on different architectures effortlessly)
Wait until you start using cargo zig-build. Suddenly it becomes way better than Go's cross compiler because you can seamlessly cross-compile rust AND C (thanks to Zig compiler of course). https://github.com/messense/cargo-zigbuild
