Module node 

The parse tree: Node and its supporting vocabulary.

Every node carries its byte span into the source string — span provenance is structural (the G0-3 ratification’s §11.3 requirement), not an afterthought: the span map that downstream consumers (isolate, tex_to_color_map, TransformMatchingTex) use is derived from these spans, so no node may ever be constructed without one.

Structs

Delim

A delimiter as named after \left, \right, or a \big-class command.

FracSpec

The generalized-fraction flavors (rule 15’s inputs).

Node

One parse-tree node: a kind plus the byte span it came from.

Span

A half-open byte range [start, end) into the source string.

Enums

AccentKind

The accent commands (both true accents and the wide over/under class).

DelimSize

The four fixed delimiter sizes of the \big family.

FragmentKind

The structural fragments the top level tolerates (per-argument SingleStringTex semantics).

Limits

How a big operator places its scripts.

LineAlign

How the lines of a multi-line block are aligned horizontally within the block’s width (the widest line’s width).

MathFont

The argument-taking math alphabet commands.

NodeKind

What a node is. See the module docs; every variant is produced by crate::parse / crate::parse_text with full span provenance.

PhantomKind

The phantom flavors.

SpaceKind

The explicit spacing commands.

StackKind

The \stackrel/\overset/\underset family.

TextStyle

The text-mode styling islands of the TexText contract.
