public class VkDescriptorPoolSize
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying descriptor pool size.
Description

Note

When creating a descriptor pool that will contain descriptors for combined image samplers of multi-planar formats, an application needs to account for non-trivial descriptor consumption when choosing the descriptorCount value, as indicated by VkSamplerYcbcrConversionImageFormatProperties::combinedImageSamplerDescriptorCount.

Valid Usage
- descriptorCount must be greater than 0
- If type is DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXT then descriptorCount must be a multiple of 4
Valid Usage (Implicit)
- type must be a valid VkDescriptorType value
See Also

VkDescriptorPoolCreateInfo

Member documentation
- type – the type of descriptor.
- descriptorCount – the number of descriptors of that type to allocate. If type is DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK_EXT then descriptorCount is the number of bytes to allocate for descriptors of this type.
