00 · wgpu Surface Probe
The smallest native-rendering example in Junkpile.
What it proves
- Tauri 2 owns the application event loop and HTML controls window.
tauri::window::WindowBuilder creates a raw native renderer window.- wgpu creates a
Surface from that window’s raw handles.
- The active adapter and backend are reported to the WebView through a Tauri command.
- Resize, minimized-window protection, surface reconfiguration, and basic loss recovery are implemented.
The renderer window contains no WebView, canvas, WebGL, or browser render path.
Run
Expected backend
- macOS: Metal
- Windows: DX12 or Vulkan, depending on the adapter and wgpu selection
- Linux: Vulkan or GLES, depending on installed drivers
