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.

How to replicate inheritance (kinda) in Rust?
It looks to me like you are trying to make a syntax tree generic over arities. I suggest you take a look at the Expr enum in syn, its variant structs, and the ast_enum_of_structs_impl macro, which is a macro that implements a trait over different Expr variants with different fields.

Rust AST Explorer
Rust makes this project easy by providing the syn crate (parsing and formatting) and WASM (for interactivity). Source code lives at https://github.com/CarlKCarlK/rust-ast-explorer. Contributions welcome.

Rust language parsers? Do you have any recommendations?
Perhaps there should, but if you look at the commit history you'll see that syn is maintained almost entirely by dtolnay (https://github.com/dtolnay/syn/graphs/contributors). Furthermore, with Rust continually adding new syntax that needs to be supported, syn can't be easy to maintain and most of the effort probably goes into making it work at all rather than optimisations.

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.

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.
