Struct egui_wgpu::WgpuConfiguration

pub struct WgpuConfiguration {
    pub supported_backends: Backends,
    pub device_descriptor: Arc<dyn Fn(&Adapter) -> DeviceDescriptor<'static>>,
    pub present_mode: PresentMode,
    pub desired_maximum_frame_latency: Option<u32>,
    pub power_preference: PowerPreference,
    pub on_surface_error: Arc<dyn Fn(SurfaceError) -> SurfaceErrorAction>,
}

Configuration for using wgpu with eframe or the egui-wgpu winit feature.

This can also be configured with the environment variables:

• WGPU_BACKEND: vulkan, dx11, dx12, metal, opengl, webgpu
• WGPU_POWER_PREF: low, high or none

Fields

supported_backends: Backends

Backends that should be supported (wgpu will pick one of these).

For instance, if you only want to support WebGL (and not WebGPU), you can set this to wgpu::Backends::GL.

By default on web, WebGPU will be used if available. WebGL will only be used as a fallback, and only if you have enabled the webgl feature of crate wgpu.

device_descriptor: Arc<dyn Fn(&Adapter) -> DeviceDescriptor<'static>>

Configuration passed on device request, given an adapter

present_mode: PresentMode

Present mode used for the primary surface.

desired_maximum_frame_latency: Option<u32>

Desired maximum number of frames that the presentation engine should queue in advance.

Use 1 for low-latency, and 2 for high-throughput.

See wgpu::SurfaceConfiguration::desired_maximum_frame_latency for details.

None = wgpu default.

power_preference: PowerPreference

Power preference for the adapter.

on_surface_error: Arc<dyn Fn(SurfaceError) -> SurfaceErrorAction>

Callback for surface errors.
