Struct ParseNodeAccentUnder 

pub struct ParseNodeAccentUnder {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub label: String,
    pub is_stretchy: Option<bool>,
    pub is_shifty: Option<bool>,
    pub base: Box<AnyParseNode>,
}

Represents accent marks placed below mathematical expressions.

This struct handles under-accents, which are diacritical marks positioned beneath base expressions, such as underbars and undertildes.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• label - The under-accent symbol
• is_stretchy - Whether the accent stretches to fit the base width
• is_shifty - Whether the accent is shifted for better positioning
• base - The expression being under-accented

LaTeX Correspondence

Corresponds to LaTeX under-accent commands:

\underline{x}    % Underline
\underbar{y}     % Underbar
\utilde{z}       % Undertilde

Usage

Under-accent nodes provide visual modifications below expressions, useful for emphasis and special mathematical notation.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

label: String

The under-accent symbol

is_stretchy: Option<bool>

Whether the accent stretches to fit the base width

is_shifty: Option<bool>

Whether the accent is shifted for better positioning

base: Box<AnyParseNode>

The expression being under-accented

Trait Implementations

impl Clone for ParseNodeAccentUnder

fn clone(&self) -> ParseNodeAccentUnder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeAccentUnder

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeAccentUnder

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