Struct ParseNodeAccent 

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

Represents accent marks placed above mathematical expressions.

This struct handles diacritical marks and accents that modify the appearance of base mathematical expressions, such as hats, bars, and tildes.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• label - The accent symbol (e.g., “^”, “-”, “~”)
• 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 accented

LaTeX Correspondence

Corresponds to LaTeX accent commands:

\hat{x}      % Hat
\bar{y}      % Bar
\tilde{z}    % Tilde
\widehat{abc} % Wide hat

Usage

Accent nodes modify the visual appearance of mathematical symbols, commonly used for vectors, complex numbers, and special notation.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

label: String

The accent symbol (e.g., “^”, “-”, “~”)

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: AnyParseNode

The expression being accented

Trait Implementations

impl Clone for ParseNodeAccent

fn clone(&self) -> ParseNodeAccent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeAccent

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeAccent

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