Struct ParseNodeGenfrac 

pub struct ParseNodeGenfrac {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub continued: bool,
    pub numer: Box<AnyParseNode>,
    pub denom: Box<AnyParseNode>,
    pub has_bar_line: bool,
    pub left_delim: Option<String>,
    pub right_delim: Option<String>,
    pub size: Option<&'static Style>,
    pub bar_size: Option<MeasurementOwned>,
}

Represents generalized fractions and binomial coefficients.

This struct handles various types of fractions including regular fractions, binomial coefficients, and other stacked expressions with optional delimiters.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• continued - Whether this is a continued fraction
• numer - The numerator expression
• denom - The denominator expression
• has_bar_line - Whether to draw a fraction bar
• left_delim - Optional left delimiter
• right_delim - Optional right delimiter
• size - The display size (Style)
• bar_size - Optional custom bar thickness

LaTeX Correspondence

Corresponds to LaTeX fraction commands:

\frac{1}{2}       % Regular fraction
\binom{n}{k}      % Binomial coefficient
\dfrac{a}{b}      % Display style fraction
\cfrac{1}{1+x}    % Continued fraction

Usage

Genfrac nodes are fundamental for representing ratios, probabilities, and complex mathematical relationships in stacked form.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

continued: bool

Whether this is a continued fraction

numer: Box<AnyParseNode>

The numerator expression

denom: Box<AnyParseNode>

The denominator expression

has_bar_line: bool

Whether to draw a fraction bar

left_delim: Option<String>

Optional left delimiter

right_delim: Option<String>

Optional right delimiter

size: Option<&'static Style>

The display size (Style) Corresponds to KaTeX’s \genfrac size parameter: If this is None, the equivalent to “auto” is used.

bar_size: Option<MeasurementOwned>

Optional custom bar thickness

Trait Implementations

impl Clone for ParseNodeGenfrac

fn clone(&self) -> ParseNodeGenfrac

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeGenfrac

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeGenfrac

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