Struct gfx_backend_empty::CommandQueue

pub struct CommandQueue;

Dummy command queue doing nothing.

Trait Implementations

impl Debug for CommandQueue

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

Formats the value using the given formatter.

impl CommandQueue<Backend> for CommandQueue

unsafe fn submit<'a, T, Ic, S, Iw, Is>(
    &mut self,
    _: Submission<Ic, Iw, Is>,
    _: Option<&()>
) where
    T: 'a + Borrow<CommandBuffer>,
    Ic: IntoIterator<Item = &'a T>,
    S: 'a + Borrow<()>,
    Iw: IntoIterator<Item = (&'a S, PipelineStage)>,
    Is: IntoIterator<Item = &'a S>, 

Submit command buffers to queue for execution. fence must be in unsignalled state, and will be signalled after all command buffers in the submission have finished execution.

unsafe fn present<'a, W, Is, S, Iw>(
    &mut self,
    _: Is,
    _: Iw
) -> Result<Option<Suboptimal>, PresentError> where
    W: 'a + Borrow<Swapchain>,
    Is: IntoIterator<Item = (&'a W, SwapImageIndex)>,
    S: 'a + Borrow<()>,
    Iw: IntoIterator<Item = &'a S>, 

Presents the result of the queue to the given swapchains, after waiting on all the semaphores given in wait_semaphores. A given swapchain must not appear in this list more than once.

unsafe fn present_surface(
    &mut self,
    _surface: &mut Surface,
    _image: (),
    _wait_semaphore: Option<&()>
) -> Result<Option<Suboptimal>, PresentError>

Present the a

fn wait_idle(&self) -> Result<(), OutOfMemory>

Wait for the queue to idle.

unsafe fn submit_without_semaphores<'a, T, Ic>(
    &mut self,
    command_buffers: Ic,
    fence: Option<&<B as Backend>::Fence>
) where
    Ic: IntoIterator<Item = &'a T>,
    T: 'a + Borrow<<B as Backend>::CommandBuffer>, 

Simplified version of submit that doesn't expect any semaphores.

unsafe fn present_without_semaphores<'a, W, Is>(
    &mut self,
    swapchains: Is
) -> Result<Option<Suboptimal>, PresentError> where
    Is: IntoIterator<Item = (&'a W, u32)>,
    W: 'a + Borrow<<B as Backend>::Swapchain>, 

Simplified version of present that doesn't expect any semaphores.
