//! Automatically generates bindings for the Vulkan API. In order to use, first create a
//! [`VkRegistry`] struct with a valid Vulkan XML file, and then call either one of the two
//! generation functions ([`gen_global()`] or [`gen_struct()`]) or a custom one. Further
//! documentation can be found in [`VkRegistry`] and [`GenConfig`], and looking over the provided
//! [examples](https://github.com/Osspial/vk-rs/tree/master/vk_generator/examples) is encouraged.
