Struct Fonts 

pub struct Fonts<'a> {
    pub sources: Vec<C8FontSource<Box<dyn RangedSource + 'a>>>,
    pub roles: Option<C8PageFonts>,
    pub embedding: FontEmbedding,
    pub glyph_aliases: Vec<NativeFontGlyphAlias>,
    pub symbol_glyphs: Vec<NativeSymbolGlyph>,
    pub symbol_font: Option<SymbolFontIdentity>,
    pub decoration_glyphs: Vec<NativeDecorationGlyph>,
    pub decoration_font: Option<SymbolFontIdentity>,
}

Font resources for native HN/C8 text.

Up to eleven ranged resources and their collection faces; roles index into sources, and several roles may share one resource. Absent optional roles and unmapped characters follow the C8PageFonts fallback rule.

Fields

sources: Vec<C8FontSource<Box<dyn RangedSource + 'a>>>

roles: Option<C8PageFonts>

Which source draws each role; sources without roles are refused.

embedding: FontEmbedding

Used program preservation; defaults to compact subsets.

glyph_aliases: Vec<NativeFontGlyphAlias>

Ordinary glyph aliases, strictly sorted by source index and character.

symbol_glyphs: Vec<NativeSymbolGlyph>

Explicit source glyphs for HN-B mode-0 symbol codes, drawn from the symbols role without fallback. Semantic text is unchanged. Native documents of another profile refuse a non-empty map; like the fonts, it is unread for documents routed to image composition.

symbol_font: Option<SymbolFontIdentity>

The font symbol_glyphs was measured on; a different symbols font is refused. Requires a nonempty map.

decoration_glyphs: Vec<NativeDecorationGlyph>

Explicit nonsemantic decoration aliases for native mode 2.

decoration_font: Option<SymbolFontIdentity>

Expected decoration font identity; requires a nonempty decoration map.
