vkGetDeviceCombinedImageSamplerIndexNVX

To get the handle for a combined image sampler, call:

uint64_t vkGetDeviceCombinedImageSamplerIndexNVX(
    VkDevice device,
    uint64_t imageViewIndex,
    uint64_t samplerIndex);

pub fn get_device_combined_image_sampler_index_nvx(
    device: vk::Device,
    image_view_index: u64,
    sampler_index: u64,
) -> u64;

• device is the logical device that will use the result handle.
• imageViewIndex is the index within the resource heap.
• samplerIndex is the index within the sampler heap.

Shaders take imageViewIndex and samplerIndex, and multiply it by VkPhysicalDeviceDescriptorHeapPropertiesEXT::imageDescriptorSize and VkPhysicalDeviceDescriptorHeapPropertiesEXT::samplerDescriptorSize respectively to obtain the descriptor offset in bytes.
