Struct ParseNodeTag 

pub struct ParseNodeTag {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub body: Vec<AnyParseNode>,
    pub tag: Vec<AnyParseNode>,
}

Represents tagged equations or expressions with labels.

This struct handles equation tags, numbers, or labels that are associated with mathematical expressions, typically for referencing.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• body - The main mathematical expression
• tag - The tag/label expressions

LaTeX Correspondence

Corresponds to LaTeX equation tagging:

\tag{1} E = mc^2
\begin{equation}\label{eq:energy}
E = mc^2
\end{equation}

Usage

Tag nodes enable equation numbering and referencing in mathematical documents, allowing readers to cite specific equations.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

body: Vec<AnyParseNode>

The main mathematical expression

tag: Vec<AnyParseNode>

The tag/label expressions

Trait Implementations

impl Clone for ParseNodeTag

fn clone(&self) -> ParseNodeTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeTag

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeTag

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