# 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.
- 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.
