Dawn Native

The dawn-native feature enables additional functionality that is supported only when the WebGPU implementation is dawn_native.

Additional functionality:

  • wgpu::DawnTogglesDeviceDescriptor may be chained on wgpu::DeviceDescriptor on device creation to enable Dawn-specific toggles on the device.

  • wgpu::DawnCacheDeviceDescriptor may be chained on wgpu::DeviceDescriptor on device creation to enable cache options such as isolation keys.

  • Synchronous adapter.CreateDevice(const wgpu::DeviceDescriptor*) may be called.

Notes:

  • Enabling this feature in the wgpu::DeviceDescriptor does nothing, but its presence in the Adapter's set of supported features means that the additional functionality is supported.
