Struct WgpuBackend 

pub struct WgpuBackend { /* private fields */ }

wgpu-based render backend. Works with WebGL2/WebGPU in browser, Vulkan/Metal/DX12 natively.

Implementations

impl WgpuBackend

pub async fn new( surface: Surface<'static>, adapter: &Adapter, width: u32, height: u32, scale_factor: f32, ) -> Result<Self, RenderError>

Create a new WgpuBackend from an existing wgpu surface + adapter.
