The dawn-native feature enables additional functionality that is supported only when the WebGPU implementation is dawn_native.
Additional functionality:
dawn::native::DawnInstanceDescriptor may be chained on wgpu::InstanceDescriptor on instance creation to pass in the platform and additional search paths, set backend validation level, and receive instance level errors.
wgpu::DawnWGSLBlocklist may be chained on wgpu::InstanceDescriptor on instance creation to block some WGSL features.
wgpu::DawnCacheDeviceDescriptor may be chained on wgpu::DeviceDescriptor on device creation to enable cache options such as isolation keys and pass in load and store functions.
Synchronous adapter.CreateDevice(const wgpu::DeviceDescriptor*) may be called.
Notes:
wgpu::DeviceDescriptor does nothing, but its presence in the Adapter's set of supported features means that the additional functionality is supported.
