I see comments about open source, safety guarantees, speed, etc, but let's be honest. The real reason why Rust was mentioned in the title is because Rust is popular now and mentioning it attracts attention.

It's the same deal with every popular language that was the new hotness at the time: "written in Python", "written in Ruby", "written in Go" from years ago, which I see less of now.

Nothing wrong with this, it's just a straightforward way of tailoring information to the target audience to maximize engagement with an ad, whether the authors did it consciously or unconsciously (maybe they like Rust a lot and mention it often).
