I recently finished a proof of concept for getting Rust code integrated into Unreal Engine.
Please let me know what you think! Unreal Engine has a lot of features that I would find it hard to walk away from, but I also love Rust, so it was a great pleasure to work on a project that bridged the two.
It looks like you can only access it if you have access to the Unreal source code (NDA/licensing reasons, probably):
You’ll need to be logged into GitHub with an account that has access to the Unreal Engine source code. If not, the link will look like a 404 – but it’s easy to request access.
