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 (a recording command buffer)

impl Device

pub fn queue(&self) -> &Queue

pub fn info(&self) -> &AdapterInfo

pub fn features(&self) -> &Features

what this device has enabled

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) behave as a lost device from now on (a lost device runs nothing any more and its resources may go at once; here the GPU may still work on the last submission: it finishes first)

pub fn validating(&self) -> bool

the validation layer watches this device

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

free what the GPU has finished with (also done by submit and wait)

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

wait for a submission -> false when timeout_ns passed first

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

wait for every submission so far

pub fn completed(&self) -> SubmitId

the last submission the GPU has finished

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

the submission id is done on the GPU (asks the driver; never waits)

pub fn memory_reserved(&self) -> u64

bytes of device and host memory the device holds in blocks

impl Device

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

impl Device

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

impl Device

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

impl Device

impl Device

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

impl Device

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

impl Device

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

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>

create_compute_pipeline with a required subgroup size (WGSL @subgroup_size, what wgsl::Output::subgroup_size returns): Features::subgroup_size_control, a power of two in Limits::subgroup_min_size ..= subgroup_max_size; size 0: the driver’s choice

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

impl Device

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

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.
