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 the core not provide a "New" derive attribute?
Tangentially, the proc macro workshop walks through building a derive macro implementing a builder pattern. From experience, I can tell I couldn't ever write proc macros just by reading the manual, going through it is really helpful https://github.com/dtolnay/proc-macro-workshop/blob/master/README.md

Help on spans for proc macros
I am working on the proc macro workshop and am a little stuck on the builder portion of the workshop. Step 08-unrecognized-attributes wants you to handle the car where the field modifier has a misspelled portion (eac instead of each)

Practical Procedural Macros in Rust
I would very much second the suggestion to do David Tolnay’s Proc Macro Workshop if you want to start understanding how to write them. I’d been writing Rust for years but always kind of avoided proc macros.
When I had a need for them, I went through only the first section of the workshop and everything clicked. You can just do the derive macro section and all the strange and scary-looking macro syntax will make sense. I realized that there is only a bit of extra syntax but it’s used very often so it can seem a little overwhelming when reading macro code.

Another good one imo is the proc-macro-workshop.

Transitioning to Rust as a company
Don't be afraid of proc macros and derive macros, they rule. Study the basic examples. Crates like darling and resources like David Tolnay's workshop will help. Write derives for your simpler traits and impress your colleagues.

What are your experiences with hack-and-learn events?
Regarding 4, I think that macros are an interesting intermediate/advanced topic. I personally loved the material from https://github.com/dtolnay/proc-macro-workshop

Procedural Macros are really hard to understand
It took me a while to get anything done. My mistake : I came accross the procedural macros workshop several times, and every time I dismissed it, thinking - meh I'll just hack together exactly what I need and move on. Then finally I figured there is no way around it. The builder exercise sounds boring but it covers the topic pretty well. And then I went on to the debug one and from there was able to build the proc macro I wanted.

Is statically compiling against glibc possible?
To compile a program with musl on a glibc system you can use cross-rs!

I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

Compiling against specific version glibc
If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

A guide to cross-compilation in Rust
There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.

Is there a definitive guide on cross-compiling with OpenSSL?
I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

Docker ARMv7 Alpine Rust builder
You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.
-
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.
-
How to you develop in containers?
Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.
-
What are some stuff that Rust isn't good at?
It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
What are some alternatives?
sccache - Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.
