Is there any native Rust in app ads framework? Build one?

Like title says, I am making Rust desktop game apps, trying to figure how to monetize and thinking about ads inside somehow, I already know of crates "wry", "webbrowser" and compatibility stuff with "winit" so I can already do ads, just is there a better way than web and web browser? If there is no native solution for Rust desktop ads, Rust being what great thing it is would be a great market, build it someone? To be clear, using Windows, Mac, and Linux platforms, winit, wgpu, egui, and whatever I need to glue those together along with an ads thing which I am still trying to find what is best, any cookieless website ads, I have website, should work for this but with all Rust can do I am just thinking native maybe or maybe not, maybe. Is there even a cross platform thing that could be used with FFI or any other cross language tech? Yeah, I know, all this when I will probably have a paid no ads version anyway, just thought I would share this idea for business, I got this one anyway sort of but still looking for cookieless ads or native maybe or maybe not, maybe. Also, I think I might need to separate out Apple Mac stuff because of Apple fees maybe or maybe not, maybe.
