Struct ParseNodeSupSub 

pub struct ParseNodeSupSub {
    pub mode: Mode,
    pub loc: Option<SourceLocation>,
    pub base: Option<Box<AnyParseNode>>,
    pub sup: Option<Box<AnyParseNode>>,
    pub sub: Option<Box<AnyParseNode>>,
}

Represents superscript and subscript combinations in mathematical expressions.

This struct handles the attachment of superscript and/or subscript expressions to a base expression, supporting complex nested structures.

Fields

• mode - The parsing mode (Mode::Math or Mode::Text)
• loc - Optional source location for error reporting
• base - The base expression being modified
• sup - Optional superscript expression
• sub - Optional subscript expression

LaTeX Correspondence

Corresponds to LaTeX superscript/subscript syntax:

x^2        % Superscript
a_i        % Subscript
x^{n+1}    % Complex superscript
a_{i,j}    % Complex subscript

Usage

SupSub nodes are fundamental for mathematical notation, allowing expressions like exponents, indices, and other modifiers to be properly positioned relative to their base.

Fields

mode: Mode

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

loc: Option<SourceLocation>

Optional source location for error reporting

base: Option<Box<AnyParseNode>>

The base expression being modified

sup: Option<Box<AnyParseNode>>

Optional superscript expression

sub: Option<Box<AnyParseNode>>

Optional subscript expression

Trait Implementations

impl Clone for ParseNodeSupSub

fn clone(&self) -> ParseNodeSupSub

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNodeSupSub

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

Formats the value using the given formatter.

impl PartialEq for ParseNodeSupSub

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