fn add_validation_error(&mut self, field: &'static str, message: &'static str)

fn arrow_head(&mut self, arrowhead: ArrowType) -> &mut Self

Style of arrowhead on the head node of an edge. This will only appear if the dir attribute is forward or both.

fn arrow_size(&mut self, arrow_size: f32) -> &mut Self

Multiplicative scale factor for arrowheads. default: 1.0, minimum: 0.0

fn arrow_tail(&mut self, arrow_tail: ArrowType) -> &mut Self

Style of arrowhead on the tail node of an edge. This will only appear if the dir attribute is back or both.

fn class(&mut self, class: String) -> &mut Self

Classnames to attach to the edge’s SVG element. Combine with stylesheet for styling SVG output using CSS classnames. Multiple space-separated classes are supported.

fn color(&mut self, color: Color<'a>) -> &mut Self

Basic drawing color for graphics, not text. For the latter, use the fontcolor attribute. If any fraction is used, the colors are drawn in series, with each color being given roughly its specified fraction of the edge.

fn color_with_colorlist(&mut self, color: ColorList<'a>) -> &mut Self

Basic drawing color for graphics, not text. For the latter, use the fontcolor attribute. if colorList has no fractions, the edge is drawn using parallel splines or lines, one for each color in the list, in the order given. The head arrow, if any, is drawn using the first color in the list, and the tail arrow, if any, the second color. This supports the common case of drawing opposing edges, but using parallel splines instead of separately routed multiedges. If any fraction is used, the colors are drawn in series, with each color being given roughly its specified fraction of the edge.

fn color_scheme(&mut self, color_scheme: String) -> &mut Self

This attribute specifies a color scheme namespace: the context for interpreting color names. In particular, if a color value has form “xxx” or “//xxx”, then the color xxx will be evaluated according to the current color scheme. If no color scheme is set, the standard X11 naming is used. For example, if colorscheme=bugn9, then color=7 is interpreted as color=“/bugn9/7”.

fn comment(&mut self, comment: String) -> &mut Self

Comments are inserted into output. Device-dependent

fn constraint(&mut self, constraint: bool) -> &mut Self

If false, the edge is not used in ranking the nodes.

fn dir(&mut self, dir: Direction) -> &mut Self

fn edge_target(&mut self, edge_target: String) -> &mut Self

fn edge_tooltip(&mut self, edge_tooltip: String) -> &mut Self

Tooltip annotation attached to the non-label part of an edge. Used only if the edge has a URL or edgeURL attribute.

fn edge_url(&mut self, edge_url: String) -> &mut Self

Weight of edge. The heavier the weight, the shorter, straighter and more vertical the edge is. default: 1, minimum: 0

fn xlabel(&mut self, xlabel: String) -> &mut Self

External label for a node or edge. The label will be placed outside of the node but near it. These labels are added after all nodes and edges have been placed.
