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 dereferencing coercion is not used here?
Try installing cargo expand, it's useful to see how macros eventually get expanded. For example, if you run cargo expand on the following code

Not too familiar with macros but does cargo-expand do what you want or did you mean something else?

Help me understand the borrowing and moving variable concept!
Yes. You can use Tools > Expand Macro on the playground or install and run cargo-expand to see what the macro expands to. It just adds a & before the argument.

How does Rust Python ffi work?
Something that may help you understand code with magic proc macros is this utility. It's basically a wrapper around a Rust compiler flag that allows you to expand macros for a file.

even more interesting are the handful of projects layering lisp style macros on top of C. i've seen several go by over the years; a quick google search brought up c-mera and cmacro.

Show HN: C programming language extension: Cedro pre-processor
To implement something like linear types[1] in C, such that each instance of type_t must be used once and only once. But I imagine this would require too much integration with the type system and code analysis.
I wish binary inclusion was provided by more languages or build systems. For small files it's a very suitable alternative to the difficulties of packaging resources when distributing an application or library.
