The surface-capabilities
feature allows querying a surface's capabilities and creating a swap chain with additional usage flags.
Additional functionality:
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:
wgpu::TextureUsage::RenderAttachment
flag is allowed to be used in wgpu::SwapChainDescriptor::usage
.
