Struct ParseNodeFont 

pub struct ParseNodeFont {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub font: String,
    pub body: Box<AnyParseNode>,
}

Represents font changes applied to mathematical expressions.

This struct handles font family changes for mathematical content, allowing different typefaces within expressions.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• font - The font family name
• body - The expression in the specified font

LaTeX Correspondence

Corresponds to LaTeX font commands:

\mathrm{dx}     % Roman/upright
\mathbf{v}     % Bold
\mathit{f}     % Italic
\mathsf{S}     % Sans-serif

Usage

Font nodes control the typeface of mathematical symbols, essential for distinguishing different types of mathematical objects (scalars, vectors, etc.).

Fields

mode: Mode

The parsing mode (Mode::Math or Mode::Text)

loc: Option<SourceLocation>

Optional source location for error reporting

font: String

The font family name

body: Box<AnyParseNode>

The expression in the specified font

Trait Implementations

impl Clone for ParseNodeFont

fn clone(&self) -> ParseNodeFont

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeFont

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeFont

fn eq(&self, other: &ParseNodeFont) -> 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.
