Trait Implementations

impl<'a, 'q> GraphWalk<'a> for GraphvizDepGraph<'q>

type Node = &'q DepNode

type Edge = (&'q DepNode, &'q DepNode)

pub fn nodes(&self) -> Nodes<'_, &'q DepNode>

Returns all the nodes in this graph.

pub fn edges(&self) -> Edges<'_, (&'q DepNode, &'q DepNode)>

Returns all of the edges in this graph.

pub fn source(&self, edge: &(&'q DepNode, &'q DepNode)) -> &'q DepNode

The source node for edge.

pub fn target(&self, edge: &(&'q DepNode, &'q DepNode)) -> &'q DepNode

The target node for edge.

impl<'a, 'q> Labeller<'a> for GraphvizDepGraph<'q>

type Node = &'q DepNode

type Edge = (&'q DepNode, &'q DepNode)

pub fn graph_id(&self) -> Id<'_>

Must return a DOT compatible identifier naming the graph.

pub fn node_id(&self, n: &&'q DepNode) -> Id<'_>

Maps n to a unique identifier with respect to self. The implementor is responsible for ensuring that the returned name is a valid DOT identifier.

pub fn node_label(&self, n: &&'q DepNode) -> LabelText<'_>

Maps n to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is just the output from node_id.

pub fn node_shape(&'a self, _node: &Self::Node) -> Option<LabelText<'a>>

Maps n to one of the graphviz shape names. If None is returned, no shape attribute is specified.

pub fn edge_label(&'a self, _e: &Self::Edge) -> LabelText<'a>

Maps e to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is in fact the empty string.

pub fn node_style(&'a self, _n: &Self::Node) -> Style

Maps n to a style that will be used in the rendered output.

pub fn edge_style(&'a self, _e: &Self::Edge) -> Style

Maps e to a style that will be used in the rendered output.
