device: Arc<Device>

queue: Arc<Queue>

Implementations

impl WgpuContext

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

pub fn new_rejecting_software( instance: Instance, surface: &Surface<'_>, compositor_gpu: Option<CompositorGpuHint>, ) -> Result<Self>

pub fn instance(display: Box<dyn WgpuHasDisplayHandle>) -> Instance

pub fn check_compatible_with_surface(&self, surface: &Surface<'_>) -> Result<()>

检查适配器是否与表面兼容

pub fn supports_dual_source_blending(&self) -> bool

检查是否支持双源混合

pub fn color_texture_format(&self) -> TextureFormat

获取彩色纹理格式

pub fn device_lost(&self) -> bool

返回 GPU 设备是否丢失（例如由于驱动崩溃、挂起/恢复）。 当返回 true 时，需要重新创建上下文。
