A comparison of operating systems written in Rust.
There are several open source operating systems written in Rust. Most of them are proofs of concepts. The only system that goes a step further is redox. It comes with a window manager as well as basic applications like an editor and a file manager. Theseus is approaching maturity with the ability to execute legacy components in a WASM sandboxed environment.
