Enum Node 

pub enum Node {
    Text(String, Span),
    ParagraphBreak(Span),
    Command {
        name: String,
        args: Vec<Arg>,
        span: Span,
    },
    Group(Vec<Node>, Span),
    Math(Vec<Node>, Span),
    DisplayMath(Vec<Node>, Span),
    Comment(String, Span),
    AlignTab(Span),
    Tilde(Span),
    Environment {
        name: String,
        args: Vec<Arg>,
        body: Vec<Node>,
        span: Span,
    },
}

A single node in the LaTeX AST.

Variants

Text(String, Span)

A run of plain text characters

ParagraphBreak(Span)

A blank line in the source - signals a paragraph break.

Command

A LaTeX command and its arguments, e.g. \textbf{hello}.

Fields

name: String

Name without the leading backslash, e.g. "textbf".

args: Vec<Arg>

span: Span

Group(Vec<Node>, Span)

A braced group {...}.

Math(Vec<Node>, Span)

Inline match: $ ... $. The span covers both $ delimiters.

DisplayMath(Vec<Node>, Span)

Display math: \[ ... \]. The span covers both delimiters.

Comment(String, Span)

A % ... line comment. THe string is the body without the leading % and without the trailing newline - the span covers the whole run, including both. Comments in AST since they can actually affect produced PDF.

AlignTab(Span)

A & column separator inside tabular/array/align and other environments.

Tilde(Span)

A ~ - a non-breaking space. Acts like a regular space for layout but forbids a line break at this point.

Environment

\begin{name} ... \end{name}. args is everything after the environment name (optionals and additional mandatory groups). body holds the parsed children; the span also covers the entire construct.

Fields

name: String

args: Vec<Arg>

body: Vec<Node>

span: Span
