How do I handle `get_swap_chain_preferred_format` returning `None`? #794

Closed expenses closed 3 years ago

After https://github.com/gfx-rs/wgpu-rs/pull/778, get_swap_chain_preferred_format can return None 'if the adapter does not support the surface'. I just had this happen on a friend's laptop with no obvious cause. Is it possible to handle this case by guessing a good swapchain format, or is the only good option to end the program?

Turns out the correct way to handle this is to pass in the surface to the compatible_surface field of RequestAdapterOptions and not have to deal with this problem 🥴🥴
