VkMemoryMapFlagBits

Bits which can be set in vkMapMemory::flags and VkMemoryMapInfo::flags, specifying additional properties of a memory map, are:

typedef enum VkMemoryMapFlagBits {

    // Provided by extensions
    VK_MEMORY_MAP_PLACED_BIT_EXT = 0x00000001,
} VkMemoryMapFlagBits;

pub struct MemoryMapFlagBits(u32);
impl MemoryMapFlagBits {
    pub const PLACED_EXT: Self = 0x00000001;
}

• VK_MEMORY_MAP_PLACED_BIT_EXT requests that the implementation place the memory map at the virtual address specified by the application via VkMemoryMapPlacedInfoEXT::pPlacedAddress, replacing any existing mapping at that address. This flag must not be used with vkMapMemory as there is no way to specify the placement address.
