VkMemoryRequirements

The VkMemoryRequirements structure is defined as:

typedef struct VkMemoryRequirements {
    VkDeviceSize size;
    VkDeviceSize alignment;
    uint32_t memoryTypeBits;
} VkMemoryRequirements;

pub struct MemoryRequirements {
    size: vk::DeviceSize, // Specified in bytes
    alignment: vk::DeviceSize, // Specified in bytes
    memory_type_bits: u32, // Bitmask of the allowed memory type indices into memoryTypes[] for this object
}

• size is the size, in bytes, of the memory allocation required for the resource.
• alignment is the alignment, in bytes, of the offset within the allocation required for the resource.
• memoryTypeBits is 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.
