Enumeration of font variants used in mathematical expression rendering.

This enum defines the various font styles available for rendering math symbols and text in KaTeX. Each variant corresponds to a specific typeface or style that can be applied to mathematical content for proper typographical presentation.

LaTeX/KaTeX Context

LaTeX provides extensive font support for mathematical typesetting, including special symbol fonts (e.g., Blackboard Bold for sets, Fraktur for certain notations). KaTeX implements these variants to ensure accurate reproduction of mathematical documents with correct symbol rendering.

Variants

Bold

Bold font variant for emphasized mathematical symbols.

BoldItalic

Bold italic font variant for bold mathematical variables.

BoldSansSerif

Bold sans-serif font variant for UI elements in math.

DoubleStruck

Double-struck (Blackboard Bold) font variant for sets (e.g., ℝ, ℕ).

Fraktur

Fraktur font variant for special mathematical notation.

Italic

Italic font variant for mathematical variables and functions.

Monospace

Monospace font variant for code and typewriter text in math.

Normal

Normal (roman) font variant for regular mathematical text.

SansSerif

Sans-serif font variant for clean, modern mathematical text.

SansSerifBoldItalic

Sans-serif bold italic font variant for emphasized sans-serif text.

SansSerifItalic

Sans-serif italic font variant for italic sans-serif text.

Script

Script font variant for calligraphic mathematical symbols.

Trait Implementations

impl Clone for FontVariant

fn clone(&self) -> FontVariant

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontVariant

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FontVariant

fn eq(&self, other: &FontVariant) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
