Honestly, I say this as a big Rust user: ignore that shit. At the level of writing a desktop app, the truth is that you're already using a vast amount of CPU and memory, and eking out performance gains on that level is not going to make a vast difference. It's very likely that your Rust code would end up being littered with .clone() and the like, and likely less performant than well-written JS. Also, V8 is an incredible piece of technology, and is not that far off being competitive with Rust or C++. In some scenarios GC (by which I mean tracing) can outperform reference counting, or even Rust-style malloc+free. The event loop architecture is also very naturally fitted to user interfaces. Ignore the HN opinionmongers and build with whatever tools you can work with. You'll be much faster and more flexible, and you'll gain an understanding of what the bottlenecks are, which you can use to do targeted optimisation later on :)
