-- When a descriptor set is updated via elements of
-- 'Vulkan.Core10.DescriptorSet.WriteDescriptorSet', members of
-- @pImageInfo@, @pBufferInfo@ and @pTexelBufferView@ are only accessed by
-- the implementation when they correspond to descriptor type being defined
-- - otherwise they are ignored. The members accessed are as follows for
-- each descriptor type:
--
-- -   For 'DESCRIPTOR_TYPE_SAMPLER', only the @sampler@ member of each
--     element of
--     'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'::@pImageInfo@ is
--     accessed.
--
-- -   For 'DESCRIPTOR_TYPE_SAMPLED_IMAGE',
--     'DESCRIPTOR_TYPE_STORAGE_IMAGE', or
--     'DESCRIPTOR_TYPE_INPUT_ATTACHMENT', only the @imageView@ and
--     @imageLayout@ members of each element of
--     'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'::@pImageInfo@ are
--     accessed.
--
-- -   For 'DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER', all members of each
--     element of
--     'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'::@pImageInfo@ are
--     accessed.
--
-- -   For 'DESCRIPTOR_TYPE_UNIFORM_BUFFER',
--     'DESCRIPTOR_TYPE_STORAGE_BUFFER',
--     'DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC', or
--     'DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC', all members of each
--     element of
--     'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'::@pBufferInfo@ are
--     accessed.
--
-- -   For 'DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER' or
--     'DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER', each element of
--     'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'::@pTexelBufferView@
--     is accessed.
--
-- When updating descriptors with a @descriptorType@ of
-- 'DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXT', none of the @pImageInfo@,
-- @pBufferInfo@, or @pTexelBufferView@ members are accessed, instead the
-- source data of the descriptor update operation is taken from the
-- 'Vulkan.Extensions.VK_EXT_inline_uniform_block.WriteDescriptorSetInlineUniformBlockEXT'
-- structure in the @pNext@ chain of
-- 'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'. When updating
-- descriptors with a @descriptorType@ of
-- 'DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR', none of the @pImageInfo@,
-- @pBufferInfo@, or @pTexelBufferView@ members are accessed, instead the
-- source data of the descriptor update operation is taken from the
-- 'Vulkan.Extensions.VK_KHR_ray_tracing.WriteDescriptorSetAccelerationStructureKHR'
-- structure in the @pNext@ chain of
-- 'Vulkan.Core10.DescriptorSet.WriteDescriptorSet'.
