There's RustPython and far more compatible than IronPython back in the day. C++ is NOT an extension of C, they diverged a lot.

>Codex CLI, uv, ripgrep, and what else?

RustDesk, Servo/Firefox, tons of gtk4-rs on Gnome and extra tools, Librsvg, CosmicDE (Fedora Atomic with Cosmic can be slightly faster than vanilla Gnome Silverblue), Ruffle, Gopher64, ArtCraft (both the vibecodec cr*p and the AI powered magical multimedia IDE doing crazy stuff which is fine).

Oh, and Harper to sharp your English skills:

Gnome might be a Rust domain tomorrow and nobody would bat an eye. Fedora/RH/IBM can rewrite the Anaconda installer in Rust in no time.
