Struct QueryPoolObject

pub struct QueryPoolObject<Device: VkHandle<Handle = VkDevice>>(/* private fields */);

Opaque handle to a query pool object

Implementations

impl<Device: VkHandle<Handle = VkDevice>> QueryPoolObject<Device>

pub const unsafe fn manage(handle: VkQueryPool, parent: Device) -> Self

Constructs from raw values

Safety

the resource must be created from the device and not freed anywhere

pub const fn unmanage(self) -> (VkQueryPool, Device)

Purges the construct (Drop will not be called for this resource)

impl<Device: VkHandle<Handle = VkDevice> + Clone> QueryPoolObject<&Device>

pub fn clone_parent(self) -> QueryPoolObject<Device>

Owning parent object by cloning it.

impl<Device: Device> QueryPoolObject<Device>

pub fn new(device: Device, info: &QueryPoolCreateInfo) -> Result<Self>

Available on crate feature Implements only.

Create a new query pool object

Failure

On failure, this command returns

• VK_ERROR_OUT_OF_HOST_MEMORY
• VK_ERROR_OUT_OF_DEVICE_MEMORY
