}

Descriptor for configuring graphics context creation.

Fields

backends: Backends

GPU backends to use

power_preference: PowerPreference

Power preference for adapter selection

force_fallback_adapter: bool

Whether to force fallback adapter

required_gpu_features: GpuFeatures

Required GPU features (panics if not available).

Use this for features that your application cannot function without.

requested_gpu_features: GpuFeatures

Requested GPU features (best-effort, logs warning if unavailable).

Use this for features that would be nice to have but are not essential.

additional_wgpu_features: Features

Additional raw wgpu features to enable (for features not covered by GpuFeatures).

limits: Limits

Required device limits

label: Option<&'static str>

Optional label for debugging
