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.

Question about lexer and parser generators in Rust
I wrote a lexer generator. It's pretty limited and poorly architected tbh, but feel free to have a look: https://github.com/dannymcgee/gramatika

Official /r/rust "Who's Hiring" thread for job-seekers and job-offerers [Rust 1.57]
I'm a huge nerd for programming languages and rendering, and to that end I've been putting together a general-purpose parsing library inspired by syn and using that to power a language server for WGSL.

Question for experienced Rustaceans
I'm probably in the minority on this one, but I really hate writing verbose, repetitive code, so I freaking love macros. I will frequently use a one-off macro just to make something like a dispatcher function easier to read by cutting down on all the pomp and circumstance. I'm also working on a small crate that makes heavy use of proc macros, which I've already gotten a ton of mileage out of since it allows me to spin up a serviceable lexer with just a few lines of code. A lot of people really dislike macros because the source is hard to read and they're onerous to debug. They're not wrong on either of those points.

Rust Tests Itself (Kind of!)
There are two testing techniques you didn't mention: Snapshot tests (which are greatly simplified using the insta crate and mutation testing (which can be done on nightly with my mutagen crate.

What's everyone working on this week (6/2022)?
How does this compare to mutagen?

Hey Rustaceans! Got an easy question? Ask here (52/2021)!
Do you mean as part of build.rs? Yes, that's certainly doable, and has been done in the past. You can use env!("OUT_DIR") for that. Examples you may want to refer to include my mutagen crate and criterion.

Uncovered Intermediate Topics
Would be great if this could include mutation testing.

Question for experienced Rustaceans
I wrote a good number of macros though, both macro_rules! and various proc_macros. The latest iteration of overflower has both, for example. mutagen is a mutation testing tool built as a proc macro, and it's helper library has a bunch of macros, too. compact_arena uses macros to tie unique lifetime tags to arenas.

Make Your Tests Bulletproof With Mutation Testing
Also there are far more mutation testing frameworks. I maintain the rust-based mutagen one. There are also LLVM-based ones (etc. mull) that can cover multiple languages (but may yield mutations not expressible in your preferred one).

Mutable Arguments Considered Harmful | micouy.github.io
Cargo (and Rust) makes it so easy to write test cases that you should really use it to find these kinds of bugs. And there are other good test crates available: mutagen, quickcheck, etc.
