Struct FontFamilyKey 

pub struct FontFamilyKey(/* private fields */);

The identity an app-supplied typeface was registered under.

FontFamily::FileBacked and FontFamily::LoadedTypeface name a typeface by its files rather than by a name inside the font, so resolution cannot compare strings from the name table. Hashing the FontFamily value once at registration and once per resolve keeps the two sides in step without walking path lists on every frame.
