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.

Show HN: Regex Derivatives (Brzozowski Derivatives)
I don't think Rust regex engine relies on this technique. I guess the main point is when you construct the DFA directly you still have the possibility of the exponential explosion of the number of states. That's why modern engines balance between NFA/DFA and lazy DFA.
Though there is an implementation that relies only on Brzozowski derivatives: https://github.com/google/redgrep

redgrep did it though: https://github.com/google/redgrep
- Redgrep – grep based on regex derivatives, matches in linear time

Speed of Rust vs. C
It couldn't figure it out from looking through ripgrep's website: does ripgrep support intersection and complement of expressions? Like eg https://github.com/google/redgrep does.
Regular languages are closed under those operations after all.

And here's how I've been trying similar thing in Rust: https://github.com/rlidwka/markdown-it.rs/blob/e5926081802089e723065bf8b5226607a3ad1d9e/src/syntax/html/utils/regexps.rs
