Struct ParseNodeSupSub 

Source
pub struct ParseNodeSupSub {
    pub mode: Mode,

    pub base: Option<Box<AnyParseNode>>,
    pub sup: Option<Box<AnyParseNode>>,

}
Expand description

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

§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
