After skimming through the author's Rust code, it appears to be a fairly straightforward port of puff.c (included in the zlib source): https://github.com/madler/zlib/blob/develop/contrib/puff/puf...
You could say it was a “puff” piece, eh, eh!?
This feels like it should have been mentioned in the article.
It makes me wonder if there was some LLM help, based on how similar the fn structure and identifier names are.
