Struct ParseNodeLap 

pub struct ParseNodeLap {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub alignment: LapAlignment,
    pub body: Box<AnyParseNode>,
}

Represents overlapping content (lap) in mathematical expressions.

This struct handles text or symbols that overlap other content, commonly used for annotations or special positioning.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• alignment - The alignment for overlapping (“l”, “r”, “c”)
• body - The overlapping content

LaTeX Correspondence

Corresponds to LaTeX lap commands:

\rlap{*}     % Right overlap
\llap{#}     % Left overlap
\clap{^}     % Center overlap

Usage

Lap nodes enable overlapping text for annotations, superscripts, or special positioning requirements.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

alignment: LapAlignment

The alignment for overlapping (“l”, “r”, “c”)

body: Box<AnyParseNode>

The overlapping content

Trait Implementations

impl Clone for ParseNodeLap

fn clone(&self) -> ParseNodeLap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeLap

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeLap

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