Struct wgpu::Queue

pub struct Queue { /* private fields */ }

Handle to a command queue on a device.

A Queue executes recorded CommandBuffer objects and provides convenience methods for writing to buffers and textures. It can be created along with a Device by calling Adapter::request_device.

Corresponds to WebGPU GPUQueue.

Implementations

impl Queue

pub fn write_buffer(&self, buffer: &Buffer, offset: BufferAddress, data: &[u8])

Schedule a data write into buffer starting at offset.

This method is intended to have low performance costs. As such, the write is not immediately submitted, and instead enqueued internally to happen at the start of the next submit() call.

This method fails if data overruns the size of buffer starting at offset.

pub fn write_texture(
    &self,
    texture: ImageCopyTexture<'_>,
    data: &[u8],
    data_layout: ImageDataLayout,
    size: Extent3d
)

Schedule a data write into texture.

This method is intended to have low performance costs. As such, the write is not immediately submitted, and instead enqueued internally to happen at the start of the next submit() call.

This method fails if data overruns the size of fragment of texture specified with size.

pub fn submit<I: IntoIterator<Item = CommandBuffer>>(&self, command_buffers: I)

Submits a series of finished command buffers for execution.

pub fn get_timestamp_period(&self) -> f32

Gets the amount of nanoseconds each tick of a timestamp query represents.

Returns zero if timestamp queries are unsupported.

pub fn on_submitted_work_done(&self) -> impl Future<Output = ()> + Send

Returns a future that resolves once all the work submitted by this point is done processing on GPU.

Trait Implementations

impl Debug for Queue

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

Formats the value using the given formatter.
