https://github.com/cynic64/render-engine (Vulkan abstraction. I should probably rename it as although my original intention was to make it a more complete rendering engine with built-in support for mesh loading, lighting, etc., it's become something different.)
This is more of a demo than a something you should try and use in your own project. The test-render-engine repository in particular is a real mess, as I had to rush because it's a school project and the deadline was looming. Pretty.rs is a real abomination. I apologize...
Maybe you can learn a little about Vulkano by reading render-engine's source code. There aren't many comments, but it does show a couple ways to do things in Vulkano that aren't well-documented. The only real things of interest are the method used to allow user-defined vertex types and storing shaders in structs.
Hopefully I can eventually turn this into a proper, safer, cleaner vulkan abstraction in Rust - but it's not even close right now.
