I just released an include_dir crate for embedding an entire directory tree into your binary. Think of it like
include_str!(), but on steroids!
Use cases I can think of would be bundling in static assets for your web app so deployment is just a case of copying around a single binary, or game assets like images, media, and textures.
In the future I'm hoping to turn this into a
proc_macro, but for now you can copy/paste a build script from the docs,
include!() it, and everything else should Just Work.
