Struct Queue 

pub struct Queue { /* private fields */ }

Available on vulkan only.

Implementations

impl Queue

pub fn as_raw(&self) -> Queue

impl Queue

pub fn raw_device(&self) -> &Device

pub fn add_signal_semaphore( &self, semaphore: Semaphore, semaphore_value: Option<u64>, )

pub fn remove_signal_semaphore(&self, semaphore: Semaphore) -> bool

Remove semaphore from the pending signal list if it is still present.

Returns true if the semaphore was found and removed. If the submit already consumed it, this is a harmless no-op that returns false.

pub fn add_wait_semaphore( &self, semaphore: Semaphore, semaphore_value: Option<u64>, stage: PipelineStageFlags, )

Stage a semaphore wait on the next crate::Queue::submit call.

semaphore_value selects the kind of payload the wait targets:

• Some(value) - wait until semaphore (a timeline semaphore) has been signalled to at least value.
• None - wait on a binary semaphore signal.

stage is the pipeline stage at which the wait blocks downstream work (e.g. vk::PipelineStageFlags::TOP_OF_PIPE to gate the entire submission, or a more specific stage when only that stage reads the synchronised resource).

pub fn remove_wait_semaphore(&self, semaphore: Semaphore) -> bool

Remove semaphore from the pending wait list if it is still present.

Returns true if the semaphore was found and removed. If the submit already consumed it, this is a no-op that returns false.

Trait Implementations

impl Debug for Queue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for Queue

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl DynResource for Queue

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

impl Queue for Queue

type A = Api

unsafe fn submit( &self, command_buffers: &[&CommandBuffer], surface_textures: &[&SurfaceTexture], (signal_fence, signal_value): (&Fence, FenceValue), ) -> Result<(), DeviceError>

Submit command_buffers for execution on GPU.

unsafe fn present( &self, surface: &Surface, texture: SurfaceTexture, ) -> Result<(), SurfaceError>

Present a surface texture to the screen.

unsafe fn get_timestamp_period(&self) -> f32

unsafe fn wait_for_idle(&self) -> Result<(), DeviceError>

Block until all previously submitted work on this queue has completed, including any pending presentations.
