Deser: Rethinking Rust Serialization (lucumr.pocoo.org)

I'm not sure if this author used an LLM, but I think you've misunderstood that paragraph. At worst, the line you're referencing is a tongue-in-check little introduction into a paragraph that describes the top-level differences in approach to serialization that the two libraries take.

deser might also just be deserialize shortened, and I was wondering if it was something focused on deserialization only. As such, I didn’t find a quick little note on the etymology to be a particularly egregious waste of words.

I think this is a case of pangram's attribution being confused. All code examples are AI generated but it places the attribution on the text that surrounds it.
