Structure specifying memory requirements.
Member documentation
- size – the size, in bytes, of the memory allocation required: for the resource.
- alignment – the alignment, in bytes, of the offset within the allocation required: for the resource.
- memoryTypeBits – a bitmask and contains one bit set for every supported memory type for the resource. Bit i is set if and only if the memory type i in the VkPhysicalDeviceMemoryProperties structure for the physical device is supported for the resource.
