Enum FontOrRef 

pub enum FontOrRef<T> {
    Font(T),
    Ref(FontRef),
}

Enum that wraps either a fontconfig-resolved font (T) or a direct FontRef.

This allows the shaping code to handle both fontconfig-resolved fonts and embedded fonts (FontRef) uniformly through the ParsedFontTrait interface.

Variants

Font(T)

A font loaded via fontconfig

Ref(FontRef)

A direct FontRef (embedded font, bypasses fontconfig)
