I'm really suspicious about this. First,
Warning: Arch Linux only has official support for systemd. [1] When using a different init system, please mention so in support requests.
- From the Arch wiki.
None of the init systems listed on that wiki are written in Rust.
Rye is some sort of Python environment configuration system. There is a Rust process manager, but it's designed for containers. There's a drop in systemd service definition runner; last updated two years ago. There are at least three init systems written in Rust, but one was last changed 4 years ago, another 5 years ago, and the third 6 years ago.
I can't find any reference that doesn't lead back to the LJ article, and nothing that comes from Arch.
Artix supports three init systems, no-one of which are written in Rust.
This has the stench is AI.
