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.

Debian Running on Rust Coreutils
The Rust implementation that we are discussing is MIT licensed and as far as I know not part of GNU.
I do not believe that "Coreutils" is trademarked by GNU.
There are other projects that use the name "Coreutils" that are not part of GNU:

Have you heard of posh: Policy-compliant Ordinary SHell?
Unsure. Would BSD CoreUtils help?

why GNU grep is fast
For things that are commonly and almost-ideally represented as text files, there’s a lot of Rust based alternatives are faster and have more features than the old unix/GNU tools: ripgrep, fd, cw, and you can find more in this list.

Nice, beats my old Rust wc through sheer brute force on my old 12c/24t server:

How to learn Rust by own tiny applications?
A lot of unix-y tools have been rewritten in rust, where the usefulness comes from it being faster or having more features. Examples: bat, cw, lsd, ripgrep, diskonaut, gping. Maybe you could find an interesting program to rewrite?

Debian Running on Rust Coreutils
Having written a Rust wc implementation a few years ago (https://github.com/Freaky/cw), I had a look at theirs.
It's pretty naive - a simple linewise read_until loop, a conditional to avoid word splitting and such if it's not needed, and for some reason it collects results into an array and prints when it's done rather than printing as it goes.
It doesn't support --files0-from like GNU wc, so isn't a drop-in replacement from that perspective. It also has the sadly common Rust trope of only supporting filenames that are valid UTF-8.
It doesn't seem overly slow considering its simplicity - usually trading blows with GNU and BSD wc. Perhaps the most glaring omission is the lack of a fast path for -c, which should reduce to a stat() call. Also unfortunate not to use the excellent bytecount crate to provide a very fast -l/m path.
The read_until loop also makes its memory use unpredictable compared with other wc's. If you run it on /dev/zero it will try to eat your computer.
What are some alternatives?
fancy-regex - Rust library for regular expressions using "fancy" features like look-around and backreferences
gping - Ping, but with a graph
build2 - build2 build system
CompactGUI - Transparently compress active games and programs using Windows 10/11 APIs [Moved to: https://github.com/IridiumIO/CompactGUI]
bsdutils - Alternative to GNU coreutils using software from FreeBSD
regex - An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.
libgnunetworker - Multithreading with GNUnet
ht - Friendly and fast tool for sending HTTP requests
mbpfan - A simple daemon to control fan speed on all MacBook/MacBook Pros (probably all Apple computers) for Linux Kernel 3 and newer
nushell - A new type of shell
