Struct ParseNodeCdLabel 

pub struct ParseNodeCdLabel {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub side: String,
    pub label: Box<AnyParseNode>,
}

Represents labels in commutative diagram (CD) environments.

This struct handles labels attached to arrows or objects in commutative diagrams, which are specialized mathematical diagrams showing relationships between objects.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• side - The side of the arrow/object where the label appears (“top”, “bottom”, “left”, “right”)
• label - The mathematical expression serving as the label

LaTeX Correspondence

Used in CD environments:

\begin{CD}
A @>f>> B
@VVgV @VVhV
C @>>k> D
\end{CD}

Usage

CD labels provide annotations for arrows and objects in commutative diagrams, helping to clarify the mathematical relationships being depicted.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

side: String

The side of the arrow/object where the label appears (“top”, “bottom”, “left”, “right”)

label: Box<AnyParseNode>

The mathematical expression serving as the label

Trait Implementations

impl Clone for ParseNodeCdLabel

fn clone(&self) -> ParseNodeCdLabel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeCdLabel

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeCdLabel

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