  --
  -- -   For descriptor set bindings created with the
  --     'Vulkan.Core12.Enums.DescriptorBindingFlagBits.DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT'
  --     bit set, all descriptors in that binding that are dynamically used
  --     /must/ have been populated before the descriptor set is
  --     <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#descriptorsets-binding consumed>.
  --
  -- -   For descriptor set bindings created without the
  --     'Vulkan.Core12.Enums.DescriptorBindingFlagBits.DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT'
  --     bit set, all descriptors in that binding that are statically used
  --     /must/ have been populated before the descriptor set is
  --     <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#descriptorsets-binding consumed>.
  --
  -- -   Descriptor bindings with descriptor type of
  --     'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK'
  --     /can/ be undefined when the descriptor set is
  --     <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#descriptorsets-binding consumed>;
  --     though values in that block will be undefined.
  --
  -- -   Entries that are not used by a pipeline /can/ have undefined
  --     descriptors.
  --
  -- If a call to 'allocateDescriptorSets' would cause the total number of
  -- descriptor sets allocated from the pool to exceed the value of
  -- 'DescriptorPoolCreateInfo'::@maxSets@ used to create
  -- @pAllocateInfo->descriptorPool@, then the allocation /may/ fail due to
  -- lack of space in the descriptor pool. Similarly, the allocation /may/
  -- fail due to lack of space if the call to 'allocateDescriptorSets' would
  -- cause the number of any given descriptor type to exceed the sum of all
  -- the @descriptorCount@ members of each element of
  -- 'DescriptorPoolCreateInfo'::@pPoolSizes@ with a @type@ equal to that
  -- type.
  --
  -- Additionally, the allocation /may/ also fail if a call to
  -- 'allocateDescriptorSets' would cause the total number of inline uniform
  -- block bindings allocated from the pool to exceed the value of
  -- 'Vulkan.Core13.Promoted_From_VK_EXT_inline_uniform_block.DescriptorPoolInlineUniformBlockCreateInfo'::@maxInlineUniformBlockBindings@
  -- used to create the descriptor pool.
  --
  -- If the allocation fails due to no more space in the descriptor pool, and
  -- not because of system or device memory exhaustion, then
  -- 'Vulkan.Core10.Enums.Result.ERROR_OUT_OF_POOL_MEMORY' /must/ be
  -- returned.
  --
  -- 'allocateDescriptorSets' /can/ be used to create multiple descriptor
  -- sets. If the creation of any of those descriptor sets fails, then the
  -- implementation /must/ destroy all successfully created descriptor set
  -- objects from this command, set all entries of the @pDescriptorSets@
  -- array to 'Vulkan.Core10.APIConstants.NULL_HANDLE' and return the error.

  -- feature is enabled, the buffer, acceleration structure, imageView, or
  -- bufferView /can/ be 'Vulkan.Core10.APIConstants.NULL_HANDLE'. Loads from
  -- a null descriptor return zero values and stores and atomics to a null
  -- descriptor are discarded. A null acceleration structure descriptor
  -- results in the miss shader being invoked.
  --
  -- If the destination descriptor is a mutable descriptor, the active
  -- descriptor type for the destination descriptor becomes @descriptorType@.
  --
  -- If the @dstBinding@ has fewer than @descriptorCount@ array elements
  -- remaining starting from @dstArrayElement@, then the remainder will be
  -- used to update the subsequent binding - @dstBinding@+1 starting at array
  -- element zero. If a binding has a @descriptorCount@ of zero, it is

  --
  -- Note
  --
  -- The same behavior applies to bindings with a descriptor type of
  -- 'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK'
  -- where @descriptorCount@ specifies the number of bytes to update while
  -- @dstArrayElement@ specifies the starting byte offset, thus in this case
  -- if the @dstBinding@ has a smaller byte size than the sum of
  -- @dstArrayElement@ and @descriptorCount@, then the remainder will be used

  -- zero. This falls out as a special case of the above rule.

  --
  -- = Description
  --
  -- If multiple 'DescriptorPoolSize' structures containing the same
  -- descriptor type appear in the @pPoolSizes@ array then the pool will be
  -- created with enough storage for the total number of descriptors of each
  -- type.
  --
  -- Fragmentation of a descriptor pool is possible and /may/ lead to
  -- descriptor set allocation failures. A failure due to fragmentation is
  -- defined as failing a descriptor set allocation despite the sum of all
  -- outstanding descriptor set allocations from the pool plus the requested
  -- allocation requiring no more than the total number of descriptors
  -- requested at pool creation. Implementations provide certain guarantees
  -- of when fragmentation /must/ not cause allocation failure, as described
  -- below.
  --
  -- If a descriptor pool has not had any descriptor sets freed since it was
  -- created or most recently reset then fragmentation /must/ not cause an
  -- allocation failure (note that this is always the case for a pool created
  -- without the
  -- 'Vulkan.Core10.Enums.DescriptorPoolCreateFlagBits.DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT'
  -- bit set). Additionally, if all sets allocated from the pool since it was
  -- created or most recently reset use the same number of descriptors (of
  -- each type) and the requested allocation also uses that same number of
  -- descriptors (of each type), then fragmentation /must/ not cause an
  -- allocation failure.
  --
  -- If an allocation failure occurs due to fragmentation, an application
  -- /can/ create an additional descriptor pool to perform further descriptor
  -- set allocations.
  --
  -- If @flags@ has the
  -- 'Vulkan.Core10.Enums.DescriptorPoolCreateFlagBits.DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT'
  -- bit set, descriptor pool creation /may/ fail with the error
  -- 'Vulkan.Core10.Enums.Result.ERROR_FRAGMENTATION' if the total number of
  -- descriptors across all pools (including this one) created with this bit
  -- set exceeds @maxUpdateAfterBindDescriptorsInAllPools@, or if
  -- fragmentation of the underlying hardware resources occurs.
  --
  -- If a @pPoolSizes@[i]::@type@ is
  -- 'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_MUTABLE_EXT', a
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeCreateInfoEXT'
  -- struct in the @pNext@ chain /can/ be used to specify which mutable
  -- descriptor types /can/ be allocated from the pool. If included in the
  -- @pNext@ chain,
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeCreateInfoEXT'::@pMutableDescriptorTypeLists@[i]
  -- specifies which kind of
  -- 'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_MUTABLE_EXT'
  -- descriptors /can/ be allocated from this pool entry. If
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeCreateInfoEXT'
  -- does not exist in the @pNext@ chain, or
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeCreateInfoEXT'::@pMutableDescriptorTypeLists@[i]
  -- is out of range, the descriptor pool allocates enough memory to be able
  -- to allocate a
  -- 'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_MUTABLE_EXT'
  -- descriptor with any supported
  -- 'Vulkan.Core10.Enums.DescriptorType.DescriptorType' as a mutable
  -- descriptor. A mutable descriptor /can/ be allocated from a pool entry if
  -- the type list in 'DescriptorSetLayoutCreateInfo' is a subset of the type
  -- list declared in the descriptor pool, or if the pool entry is created
  -- without a descriptor type list. Multiple @pPoolSizes@ entries with
  -- 'Vulkan.Core10.Enums.DescriptorType.DESCRIPTOR_TYPE_MUTABLE_EXT' /can/
  -- be declared. When multiple such pool entries are present in
  -- @pPoolSizes@, they specify sets of supported descriptor types which
  -- either fully overlap, partially overlap, or are disjoint. Two sets fully
  -- overlap if the sets of supported descriptor types are equal. If the sets
  -- are not disjoint they partially overlap. A pool entry without a
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeListEXT'
  -- assigned to it is considered to partially overlap any other pool entry
  -- which has a
  -- 'Vulkan.Extensions.VK_EXT_mutable_descriptor_type.MutableDescriptorTypeListEXT'
  -- assigned to it. The application /must/ ensure that partial overlap does
  -- not exist in @pPoolSizes@.
  --
  -- Note
  --
  -- The requirement of no partial overlap is intended to resolve ambiguity
  -- for validation as there is no confusion which @pPoolSizes@ entries will
  -- be allocated from. An implementation is not expected to depend on this
  -- requirement.
