Struct WgpuContext 

pub struct WgpuContext {
    pub device: Device,
    pub queue: Queue,
    pub surface: Surface<'static>,
    pub config: SurfaceConfiguration<Vec<TextureFormat>>,
    pub depth_format: TextureFormat,
    pub surface_view_format: TextureFormat,
    pub msaa_samples: u32,
    pub anisotropy_clamp: u16,
    pub render_path: RenderPath,
    pub pipeline_settings_version: u64,
}

Core wgpu context holding GPU handles.

This struct owns the fundamental wgpu resources needed for rendering:

• device: GPU device for resource creation
• queue: Command submission queue
• surface: Window surface for presentation
• config: Surface configuration (format, present mode, etc.)

It also manages the depth buffer texture which is recreated on resize.

Fields

device: Device

The wgpu device for GPU operations

queue: Queue

The command queue for submitting work

surface: Surface<'static>

The window surface for presentation

config: SurfaceConfiguration<Vec<TextureFormat>>

Surface configuration

depth_format: TextureFormat

Depth buffer format

surface_view_format: TextureFormat

msaa_samples: u32

anisotropy_clamp: u16

render_path: RenderPath

The active render path. Stored for runtime branching in the frame graph.

pipeline_settings_version: u64

Version counter for pipeline-affecting settings (HDR, MSAA, RenderPath). Incremented when these settings change, used to invalidate L1 pipeline cache.

Implementations

impl WgpuContext

pub async fn new<W>( window: W, init_config: &RendererInitConfig, settings: &RendererSettings, width: u32, height: u32, ) -> Result<WgpuContext, Error>

where W: HasWindowHandle + HasDisplayHandle + Send + Sync + 'static,

pub fn resize(&mut self, width: u32, height: u32)

pub fn set_vsync(&mut self, vsync: bool)

Dynamically reconfigure the surface present mode for VSync toggling.

This is a lightweight operation — only the surface configuration is resubmitted; no GPU resources are destroyed or recreated.

pub fn create_depth_texture( device: &Device, config: &SurfaceConfiguration<Vec<TextureFormat>>, format: TextureFormat, ) -> TextureView

pub fn size(&self) -> (u32, u32)

Returns the current surface dimensions.
