Description

https://gist.github.com/db48x/ac5185816f1b921bb8ca804883165e17

No particular arguments needed.

I expected there to be an impl glyph_row with accessor methods for the bitfield in this struct.

Research direction

Start with the linked gist and reproduce bindgen's output for the glyph_row struct. Inspect the generated bindings and the bitfield-handling entry point to determine why the accessor impl glyph_row is missing. Done means the reported bitfield produces the expected accessor methods.
