public class VkMemoryDedicatedRequirements
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing dedicated allocation requirements of buffer and image resources.
Description

To determine the dedicated allocation requirements of a buffer or image resource, add a VkMemoryDedicatedRequirements structure to the pNext chain of the VkMemoryRequirements2 structure passed as the pMemoryRequirements parameter of GetBufferMemoryRequirements2 or GetImageMemoryRequirements2, respectively.

Constraints on the values returned for buffer resources are:
- requiresDedicatedAllocation may be TRUE if the pNext chain of VkBufferCreateInfo for the call to vkCreateBuffer used to create the buffer being queried included a VkExternalMemoryBufferCreateInfo structure, and any of the handle types specified in VkExternalMemoryBufferCreateInfo::handleTypes requires dedicated allocation, as reported by GetPhysicalDeviceExternalBufferProperties in VkExternalBufferProperties::externalMemoryProperties.externalMemoryFeatures. Otherwise, requiresDedicatedAllocation will be FALSE.
- When the implementation sets requiresDedicatedAllocation to TRUE, it must also set prefersDedicatedAllocation to TRUE.
- If BUFFER_CREATE_SPARSE_BINDING_BIT was set in VkBufferCreateInfo::flags when buffer was created, then both prefersDedicatedAllocation and requiresDedicatedAllocation will be FALSE.
Constraints on the values returned for image resources are:
- requiresDedicatedAllocation may be TRUE if the pNext chain of VkImageCreateInfo for the call to CreateImage used to create the image being queried included a VkExternalMemoryImageCreateInfo structure, and any of the handle types specified in VkExternalMemoryImageCreateInfo::handleTypes requires dedicated allocation, as reported by GetPhysicalDeviceImageFormatProperties2 in VkExternalImageFormatProperties::externalMemoryProperties.externalMemoryFeatures. Otherwise, requiresDedicatedAllocation will be FALSE.
- If IMAGE_CREATE_SPARSE_BINDING_BIT was set in VkImageCreateInfo::flags when image was created, then both prefersDedicatedAllocation and requiresDedicatedAllocation will be FALSE.
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_MEMORY_DEDICATED_REQUIREMENTS

```
 struct VkMemoryDedicatedRequirements {
     VkStructureType sType();
     void * pNext();
     VkBool32 prefersDedicatedAllocation();
     VkBool32 requiresDedicatedAllocation();
