Needs more detail. Prior art is snix/tvix? @RossComputerGuy is working on eval? We've talked about the Store layer being appropriate for Rustification as it is way simpler than the language layer.

I am already starting a rewrite here: https://github.com/DigitalBrewStudios/rust-nix my aim is starting with the eval which has many benefits than the store layer.

I fear like this project would be nothing but setting up some poor intern up for failure. Pulling this off successfully would at the very least require some intense amounts of preparation and mentoring from deeply experienced people in the code base. Even seemingly simple and contained tasks like "get Rust<->C++ interop to work" can quickly turn into nightmares of debugging deep internals of build systems and linkers.

Am I missing something or are there no commits? I don't think pressing "fork" and renaming the repo is a noteworthy feat, and given "starting with the eval" I must assume that this is a very naive and uninformed statement that has yet to make first contact with the harsh reality that is this code base.

100%, I was going to mention this, It doesn't seem that GSOC would be appropriate for this kinda of work.

Sorry I should have rephrased it, beginning to rewrite parts of nix in rust. So we are starting to get cpp -> rust interup working correctly and hooked up with meson for lib-expr-rs eval, while thinking about the benefits of what rust could bring to the table. I haven't pushed any changes but I have made an announcement publicly on our discord, we are going to work on this.

As @tomberek mentioned, I've been working on my own implementation. It is far from complete and not fully functional yet.
