Expand description

A toc node — a compile-time table-of-contents placeholder.

A toc is a LEAF that, at compile time, resolves to a multi-line tab-leader text block by collecting all heading nodes across the whole document that match its selector (match-role and/or match-style). Each row in the output is formatted as: {heading text}\t{page number}, joined by newlines.

The synthesised TextNode uses tab-leader mode so the text engine fills the gap between heading text and page number with the leader glyph (default "."), and right-aligns the page number.

At least one of match_role or match_style must be set; when both are absent the toc collects nothing and an advisory toc.no_selector is emitted by the validator.

Fields§

§id: String§name: Option<String>§role: Option<String>§match_role: Option<String>

Select heading nodes whose role equals this. None = no role filter.

§match_style: Option<String>

Select heading nodes whose style equals this. None = no style filter.

§leader: Option<String>

Leader glyph for the dotted fill between title and page number (default "." when omitted).

§folio_style: Option<String>

Folio numbering style for the page numbers ("decimal" / "lower-roman" / "upper-roman").

§x: Option<PropertyValue>§y: Option<PropertyValue>§w: Option<PropertyValue>§h: Option<PropertyValue>§style: Option<String>§fill: Option<PropertyValue>§font_family: Option<PropertyValue>§font_size: Option<PropertyValue>§opacity: Option<f64>§visible: Option<bool>§locked: Option<bool>§anchor: Option<String>

Page-relative placement anchor (one of the nine named positions, e.g. "bottom-right"). When present and recognized, the compile step derives the node’s x and/or y from the page and node dimensions. An explicitly- authored x or y always wins.

§anchor_zone: Option<String>

Optional safe-zone reference for the anchor. See RectNode::anchor_zone.

§anchor_sibling: Option<String>

Optional sibling node id for sibling-relative anchor positioning. See RectNode::anchor_sibling.

§anchor_edge: Option<String>

Adjacent-placement edge relative to anchor-sibling: above/below/before/after. See RectNode::anchor_edge.

§anchor_gap: Option<Dimension>

Gap (px) between this node and its anchor-sibling edge when anchor-edge is set. See RectNode::anchor_gap.

§anchor_parent: Option<bool>

Parent-relative anchor toggle. See RectNode::anchor_parent.

§source_span: Option<Span>

Source declaration span, when available.

§unknown_props: BTreeMap<String, UnknownProperty>

Unknown properties preserved for forward-compat.
