# Surface Capabilities
|
||
|
|
|
||
|
|
The `surface-capabilities` feature allows querying a surface's capabilities and creating a swap chain with additional usage flags.
|
||
|
|
|
||
|
|
Additional functionality:
|
||
|
|
- Adds `wgpu::Device::GetSupportedSurfaceUsage(wgpu::Surface)` method for querying the surface's supported usage flags. One or the combination of these flags can be used to create a swap chain.
|
||
|
|
|
||
|
|
Example Usage:
|
||
|
|
```
|
||
|
|
wgpu::TextureUsage supportedUsage = device.GetSupportedSurfaceUsage(surface);
|
||
|
|
|
||
|
|
wgpu::SwapChainDescriptor desc = {};
|
||
|
|
// set usage flags.
|
||
|
|
desc.usage = supportedUsage;
|
||
|
|
|
||
|
|
device.CreateSwapChain(surface, &desc);
|
||
|
|
```
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
- If this feature is not enabled, only `wgpu::TextureUsage::RenderAttachment` flag is allowed to be used in `wgpu::SwapChainDescriptor::usage`.
