Struct Backend 

pub struct Backend { /* private fields */ }

The GPU device/queue/surface — inserted as a resource once acquisition finishes (see Read<Backend>, safe to use unwrapped anywhere from SystemStage::Ready onward). No raw wgpu type is exposed on it besides through the dedicated escape hatches on the wrapper types built on top of it.

Implementations

impl Backend

pub fn surface_width(&self) -> u32

pub fn surface_height(&self) -> u32

pub fn surface_format(&self) -> TextureFormat

pub fn features(&self) -> DeviceFeatures

pub fn limits(&self) -> DeviceLimits

pub fn dispatch_compute(&self, record: impl FnOnce(&mut ComputePass<'_>))

Records and submits a compute pass immediately, in its own command encoder — not deferred to any render stage, since compute work doesn’t need a frame to exist. Read a result back with Buffer::read once the pass has run.
