Struct Device 

pub struct Device { /* private fields */ }

a logical GPU device: creates resources, records commands, owns the queue

Implementations

impl Device

pub fn encoder(&self) -> Result<CommandEncoder<'_>>

a command encoder

impl Device

pub fn queue(&self) -> &Queue

pub fn info(&self) -> &AdapterInfo

pub fn features(&self) -> &Features

pub fn limits(&self) -> &Limits

pub fn level(&self) -> Level

pub fn is_lost(&self) -> bool

the device was lost: every call fails with DeviceLost; create a new device

pub fn test_lose(&self)

(test aid) the device is destroyed: the browser’s own way of losing it

pub fn validating(&self) -> bool

pub fn poll(&self) -> Result<()>

what the browser has said since the last look (nothing to free here)

pub fn wait(&self, id: SubmitId, _timeout_ns: u64) -> Result<bool>

the browser cannot wait on this thread: at once whether the submission is done

pub fn wait_idle(&self) -> Result<()>

pub fn completed(&self) -> SubmitId

pub fn is_done(&self, id: SubmitId) -> bool

the submission id is done on the GPU (the browser’s answer comes with its event loop)

pub fn memory_reserved(&self) -> u64

what the buffers and textures asked for (the browser says nothing about its own memory)

impl Device

pub fn create_buffer(&self, desc: &BufferDesc) -> Result<Buffer>

impl Device

pub fn create_texture(&self, desc: &TextureDesc) -> Result<Texture>

pub fn create_sampler(&self, d: &SamplerDesc) -> Result<Sampler>

impl Device

pub fn create_bind_group_layout( &self, bindings: &[Binding], ) -> Result<BindGroupLayout>

pub fn create_pipeline_layout( &self, desc: &PipelineLayoutDesc<'_>, ) -> Result<PipelineLayout>

groups: at most BIND_GROUPS_MAX, and with push constants at most 3 (the last is theirs)

pub fn create_bind_group(&self, desc: &BindGroupDesc<'_>) -> Result<BindGroup>

pub fn create_bindless(&self, _desc: &BindlessDesc) -> Result<Bindless>

(level Voll)

impl Device

pub fn create_compute_pipeline( &self, desc: &ComputePipelineDesc<'_>, ) -> Result<ComputePipeline>

pub fn create_compute_pipeline_sized( &self, desc: &ComputePipelineDesc<'_>, size: u32, ) -> Result<ComputePipeline>

(a required subgroup size: not built in the browser; size 0 is the plain pipeline)

pub fn create_render_pipeline( &self, desc: &RenderPipelineDesc<'_>, ) -> Result<RenderPipeline>

pub fn create_timestamps(&self, _count: u32) -> Result<Timestamps>

(not built in the browser: Features::timestamps is false; WebGPU has them only at the start and the end of a pass)

impl Device

pub fn create_swapchain( &self, surface: &Surface, desc: &SwapchainDesc, ) -> Result<Swapchain>

Trait Implementations

impl Clone for Device

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
