}

A connector node — a semantic arrow that declares from/to target node ids and, at COMPILE time, resolves those targets’ bounding boxes to draw a straight line between anchor points on their edges.

A connector has NO authored geometry (x/y/w/h): its endpoints are DERIVED from the resolved boxes of from and to, so when a target moves the connector reroutes automatically (the boxes are recomputed each compile). It is a stroke-only LEAF: it has a stroke/stroke_width (no fill).

An optional owned label is authored as span children inside the connector’s { … } block (the same model as a shape or text node). When spans are present the label is rendered at the geometric midpoint of the routed polyline, centered in a small auto-sized text box. text-style is the style ref applied to those spans. When spans is empty (the default) the connector renders exactly as today — no extra output, byte-identical.

Unit 1 renders a STRAIGHT line between the two resolved anchors with NO arrowhead markers (Unit 2) and NO orthogonal routing (Unit 3); the route and marker_* attributes are stored + validated now but render straight / headless until those units land.

Fields

id: String

name: Option<String>

role: Option<String>

from: Option<String>

The source target node id (the box the arrow starts from).

to: Option<String>

The destination target node id (the box the arrow points to).

from_anchor: Option<String>

Source-edge anchor (top/bottom/left/right/center/auto). Absent or unrecognized is treated as "auto" at compile time.

to_anchor: Option<String>

Destination-edge anchor (top/bottom/left/right/center/auto).

route: Option<String>

Routing mode (straight(default)/orthogonal). Orthogonal is Unit 3: stored + validated now, rendered as a straight line until then.

marker_start: Option<String>

Start-cap marker (none(default)/arrow). Markers are Unit 2: stored + validated now, rendered headless until then.

marker_end: Option<String>

End-cap marker (none(default)/arrow). Markers are Unit 2.

stroke: Option<PropertyValue>

stroke_width: Option<PropertyValue>

opacity: Option<f64>

visible: Option<bool>

locked: Option<bool>

rotate: Option<Dimension>

style: Option<String>

text_style: Option<String>

Style ref applied to the owned label text (mirrors ShapeNode::text_style). None when no label style is authored (label inherits document defaults).

spans: Vec<TextSpan>

The owned label spans rendered at the connector’s midpoint. Empty (the default) means no label — the connector renders exactly as a span-less connector. Same model as ShapeNode::spans and TextNode::spans.

source_span: Option<Span>

Source declaration span, when available.

unknown_props: BTreeMap<String, UnknownProperty>

Unknown properties preserved for forward-compat.

Trait Implementations

impl Clone for ConnectorNode

fn clone(&self) -> ConnectorNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectorNode

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

Formats the value using the given formatter.

impl PartialEq for ConnectorNode

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