/**
 * Specify a dedicated memory allocation resource.
 * 
 * Valid Usage
 * 
 * 
 * At least one of {@code image} and {@code buffer} must be {@code VK_NULL_HANDLE}
 * If {@code image} is not {@code VK_NULL_HANDLE}, {@link VkMemoryAllocateInfo}{@code ::allocationSize} must equal the {@link VkMemoryRequirements}{@code ::size} of the image
 * If {@code image} is not {@code VK_NULL_HANDLE}, {@code image} must have been created without {@link VK10#VK_IMAGE_CREATE_SPARSE_BINDING_BIT IMAGE_CREATE_SPARSE_BINDING_BIT} set in {@link VkImageCreateInfo}{@code ::flags}
 * If {@code buffer} is not {@code VK_NULL_HANDLE}, {@link VkMemoryAllocateInfo}{@code ::allocationSize} must equal the {@link VkMemoryRequirements}{@code ::size} of the buffer
 * If {@code buffer} is not {@code VK_NULL_HANDLE}, {@code buffer} must have been created without {@link VK10#VK_BUFFER_CREATE_SPARSE_BINDING_BIT BUFFER_CREATE_SPARSE_BINDING_BIT} set in {@link VkBufferCreateInfo}{@code ::flags}
 * If {@code image} is not {@code VK_NULL_HANDLE} and {@link VkMemoryAllocateInfo} defines a memory import operation, the memory being imported must also be a dedicated image allocation and {@code image} must be identical to the image associated with the imported memory.
 * If {@code buffer} is not {@code VK_NULL_HANDLE} and {@link VkMemoryAllocateInfo} defines a memory import operation, the memory being imported must also be a dedicated buffer allocation and {@code buffer} must be identical to the buffer associated with the imported memory.
 * 
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code sType} must be {@link KHRDedicatedAllocation#VK_STRUCTURE_TYPE_MEMORY_DEDICATED_ALLOCATE_INFO_KHR STRUCTURE_TYPE_MEMORY_DEDICATED_ALLOCATE_INFO_KHR}
 * {@code pNext} must be {@code NULL}
 * If {@code image} is not {@link VK10#VK_NULL_HANDLE NULL_HANDLE}, {@code image} must be a valid {@code VkImage} handle
 * If {@code buffer} is not {@link VK10#VK_NULL_HANDLE NULL_HANDLE}, {@code buffer} must be a valid {@code VkBuffer} handle
 * Both of {@code buffer}, and {@code image} that are valid handles must have been created, allocated, or retrieved from the same {@code VkDevice}
 * 
 * 
 * Member documentation
 * 
 * 
 * {@code sType} – the type of this structure.
