desired_extension deprecated with no replacement? #247

Closed hw762 closed 9 months ago

hw762 commented 10 months ago

I got warnings about its deprecation. However, it is not documented and there is no replacement

charles-lunarg commented 10 months ago

Yes, it will be removed in a future version. There currently is no replacement, however that is because the feature is not suitable in its current form.

The gist of the problem with the current API is that there is no good way to know what was and wasn't enabled after you selected a physical device. An application must not use things that were not enabled, so this is a rather important thing to know.

See #103 for more details.

I forgot there is a replacement.

Once you select your physical device, you can use enable_extension_if_present to enable extensions on it, and the return value tells you whether the extension is available.
