Vulkan

Fireball library and generator for Vulkan.

Features

• Generates an Api struct with function references instead of global state, loaded in three stages (load -> set_instance -> set_device).
• Parses enums into strongly typed, distinct enums instead of untyped integers (VK_IMAGE_LAYOUT_GENERAL -> ImageLayout::General).
• Handles are typed structs sharing a Handle interface (VkDevice -> Device).
• Struct fields and command parameters are converted to snake case with prefixes stripped (pNext -> next, pAllocateInfo -> allocate_info).
• Every struct gets a DEFAULT constant with the required s_type field filled in (ApplicationInfo::DEFAULT).
• Remaining constants are generated as top-level typed constants (VK_WHOLE_SIZE -> WHOLE_SIZE: u64).
• Only includes core and cross-vendor extensions (KHR and EXT).
• Every command starts as a panic stub and is swapped out when its level is loaded, so missing commands fail loudly.

Usage

var vk = vulkan::Api::load().expect("failed to load libvulkan");

// create the instance
var instance_info = vulkan::InstanceCreateInfo::DEFAULT with { ... };
var instance: vulkan::Instance;

vk.create_instance(&instance_info, null, &instance);
vk.set_instance(instance);

// create the device
var device_info = vulkan::DeviceCreateInfo::DEFAULT with { ... };
var device: vulkan::Device;

vk.create_device(physical_device, &device_info, null, &device);
vk.set_device(device);
