Bort

Bort is a vulkan wrapper on top of ash and vulkan memory allocator aiming to...

• reduce some boilerplate
• reference count resource dependencies (with Arc or Rc depending on the rc feature flag)
• call destructors with Drop so you don't need to manage destroy_x functions
• store create-info properties inside objects
• provide convenient defaults for create-info properties
• while also being compatible with "raw" ash::vk structs

This repo consists of 2 crates:

• bort-vk - vulkan wrapper. crates.io link
• bort-vma - vulkan memory allocator wrapper. crates.io link

Example: creating a descriptor set...

{
	let layout_binding = DescriptorSetLayoutBinding {
		binding: 0,
		descriptor_type: vk::DescriptorType::UNIFORM_BUFFER,
		descriptor_count: 1,
		stage_flags: vk::ShaderStageFlags::FRAGMENT | vk::ShaderStageFlags::VERTEX,
		..Default::default()
	};
	let layout_properties = DescriptorSetLayoutProperties::new_default(vec![layout_binding]);
	// new_from_set_layout is a convenience function that automatically creates a pool and layout
	// the pool and layout are stored inside the `descriptor_set` struct
	let descriptor_set = DescriptorSet::new_from_set_layout(device, camera_layout_properties)?;

	info!("descriptor pool handle: {:?}", descriptor_set.pool().handle());
	info!("descriptor layout create flags: {:?}" descriptor_set.layout().properties().flags);
}
// free_descriptor_sets is called upon drop

Oh, also there's very little vulkan spec validity checking. I don't really care because that's what the validation layers are for imo. Shout out to vulkano, if you want enforced spec compliance, that's the place to go!
