    pub font_bold: Option<bool>,
    pub font_italic: Option<bool>,

}

Text formatting parameters for the single-line layout API.

Controls font selection, size, and text color. All fields are optional and fall back to the typesetter’s defaults (default font, default size, default text color).

Fields

font_family: Option<String>

Font family name (e.g., “Noto Sans”, “monospace”). None means use the default font.

font_weight: Option<u32>

Font weight (100-900). Overrides font_bold.

font_bold: Option<bool>

Shorthand for weight 700. Ignored if font_weight is set.

font_italic: Option<bool>

Italic style.

font_size: Option<f32>

Font size in pixels. None means use the default size.

color: Option<[f32; 4]>

Text color (RGBA, 0.0-1.0). None means use the typesetter’s text color.

features: Vec<FontFeature>

Discretionary OpenType features to toggle during shaping (ligatures, small caps, tabular numerals, stylistic sets, …). Empty = font defaults.

hyphenation: Option<Hyphenation>

Hyphenation (Knuth-Liang dictionary + soft-hyphen breaks) for line wrapping. None = disabled (default); most useful for justified prose. See Hyphenation.
