Vulkan-Loader VS Vulkan-Headers

Take a look at Vulkan Loader Debugging, try running vulkaninfo with set VK_LOADER_DEBUG=all.

probably not given this response from 2021 https://github.com/KhronosGroup/Vulkan-Loader/issues/536

Every program that needs Vulkan does indeed link against and call something with a well-known, long-time stable ABI. This is normally Vulkan-Loader, which provides libvulkan. For OpenGL, libglvnd is a nearly equivalent library that fulfills largely the same function and provides libGL/libGLES/etc.

I'm reading through the official docs before I start a tutorial. The docs mention the loader but not very often. It does link to the loader's docs on github. I've read most of that. I still don't understand if it's an integral part of the API or just a tooling for certain use cases (multiple drivers, complex validation, etc.). I also listened to a webinar about the loader and the speaker claims he is the owner of the loader. That made me even more confused. Can someone please fill me in? Do all Vulkan apps interface with the loader before the driver? Thanks.

It's from here: https://github.com/KhronosGroup/Vulkan-Loader/blob/393e23f91d21ce117c19e8c42e084477c3a25c7c/tests/framework/test_util.h

Not exactly sure, but what you describe seems similar to the issue https://github.com/KhronosGroup/Vulkan-Loader/issues/776 .

This would be good to read to understand why some of the things are the way they are. https://github.com/KhronosGroup/Vulkan-Loader/blob/master/docs/LoaderApplicationInterface.md

Understand Wayland concepts: Familiarize yourself with the basic concepts and principles of Wayland. This will help you gain a solid understanding of how the system works. You can refer to the official Wayland documentation (https://wayland.freedesktop.org/docs/html/) and the Wayland book (https://wayland-book.com/). Learn Rust: If you're not already proficient in Rust, take some time to learn the language. The Rust Book (https://doc.rust-lang.org/book/) is a great place to start. Study existing Wayland compositors: Since you mentioned Anvil and smallvil, you can study their source code to gain insights into how they're designed and implemented. Try to understand the structure and how different components interact with each other. Dive into Smithay: Smithay (https://github.com/Smithay/smithay) is a Rust library for building Wayland compositors. Familiarize yourself with the library and its components. You can start by studying the provided examples and reading the API documentation. Learn graphics programming: Since you're interested in graphics effects, you'll need to learn about graphics programming concepts, such as shaders, framebuffers, and texturing. Vulkan (https://www.vulkan.org/) is a popular graphics API that you can use with Rust. Check out the following resources to learn more about Vulkan and graphics programming in Rust: Vulkan Tutorial (https://vulkan-tutorial.com/) gfx-rs (https://github.com/gfx-rs/gfx), a Rust graphics library Vulkano (https://github.com/vulkano-rs/vulkano), a safe, pure-Rust wrapper around the Vulkan API Start small: Break down the compositor project into smaller, manageable tasks. Begin by implementing basic functionality, like setting up a window and drawing simple shapes. Gradually add more features, such as input handling and window management. Ask for help: Join the Wayland and Rust communities to ask questions and seek advice. You can find them on forums, mailing lists, and chat platforms like Discord or IRC. The Wayland mailing list (https://lists.freedesktop.org/mailman/listinfo/wayland-devel) and the Rust programming subreddit (https://www.reddit.com/r/rust/) are good places to start. Iterate and experiment: As you progress, keep experimenting with different graphics effects and shaders. Try to implement the features you're interested in, such as blur, window previews, and window switching.

You might look at the Vulkan API: https://www.vulkan.org/. There are bindings in many languages, including Haskell (I have personally used https://hackage.haskell.org/package/vulkan).
