/**
* Structure specifying descriptor buffer info.
*
* Valid Usage
*
*
* - {@code offset} must be less than the size of {@code buffer}
* - If {@code range} is not equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, {@code range} must be greater than 0
* - If {@code range} is not equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, {@code range} must be less than or equal to the size of {@code buffer} minus {@code offset}
*
*
* Valid Usage (Implicit)
*
*
* - {@code buffer} must be a valid {@code VkBuffer} handle
*
*
* See Also
*
* {@link VkWriteDescriptorSet}
*
* Member documentation
*
*
* - {@code buffer} – the buffer resource.
* - {@code offset} – the offset in bytes from the start of {@code buffer}. Access to buffer memory via this descriptor uses addressing that is relative to this starting offset.
* - {@code range} – the size in bytes that is used for this descriptor update, or {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE} to use the range from {@code offset} to the end of the buffer.
*
*
Note
*
* When using {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, the effective range must not be larger than the maximum range for the descriptor type ( maxUniformBufferRange or maxStorageBufferRange). This means that {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE} is not typically useful in the common case where uniform buffer descriptors are suballocated from a buffer that is much larger than {@code maxUniformBufferRange}.
*
*
* For {@link VK10#VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC} and {@link VK10#VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC} descriptor types, {@code offset} is the base offset from which the dynamic offset is applied and {@code range} is the static size used for all dynamic offsets.
