Struct GpuContext 

pub struct GpuContext {
    pub adapter: Adapter,
    pub device: Device,
    pub queue: Queue,
}

A device and queue ready for rendering.

Fields

adapter: Adapter

Physical GPU the device was created on.

device: Device

Logical device that owns all GPU resources.

queue: Queue

Command queue for uploads and submissions.

Implementations

impl GpuContext

pub async fn new( instance: &Instance, surface: Option<&Surface<'_>>, ) -> Result<Self, GpuError>

Requests an adapter (compatible with surface, when given) and a device with default limits, which every WebGPU implementation supports.

A power preference is what makes wgpu rank adapters: without one it takes the first it finds, which on Linux can be Vulkan on the CPU with the real GPU right there on GL. An interface needs little, so it asks for the GPU that spends the least; WGPU_POWER_PREF overrides that. When the adapter cannot give the limits needed, as an old GPU may not, the others get a turn.
