Function layout 

pub fn layout(
    node: &MathNode,
    font: &MathFont,
    style: MathStyle,
) -> Result<MathBox, Error>

Lay out node in style using STIX Two Math metrics.

Every dimension on the returned MathBox is a Dim. Missing glyphs and unsupported constructs are errors — never a substitute glyph.

Arguments

• node — parsed math tree.
• font — face providing MATH constants and glyph metrics.
• style — TeX math style (Display, Text, scripts).

Returns

A box tree ready for SVG, PNG, or egui emission.

Errors

• Error::Font — glyph missing from the face.
• Error::Unsupported — construct or MATH table the engine will not fake.
• Error::Malformed — invalid structure discovered during layout.

Examples

use latex_rust::{layout, parse, MathFont, MathStyle};

let ast = parse(r"\frac{1}{2}").unwrap();
let font = MathFont::stix_two_math().unwrap();
let boxed = layout(&ast, &font, MathStyle::Text).unwrap();
assert!(!boxed.width.is_zero());
