Struct Node 

pub struct Node(/* private fields */);

A node in the IR graph.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Node

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

Formats the value using the given formatter.

impl<'a> GraphWalk<'a, Node, Edge<'a>> for Graph<'a>

fn nodes(&'a self) -> Cow<'a, [Node]>

Returns all the nodes in this graph.

fn edges(&'a self) -> Cow<'a, [Edge<'a>]>

Returns all of the edges in this graph.

fn source(&'a self, edge: &Edge<'_>) -> Node

The source node for edge.

fn target(&'a self, edge: &Edge<'_>) -> Node

The target node for edge.

impl<'a> Labeller<'a, Node, Edge<'a>> for Graph<'a>

fn graph_id(&'a self) -> Id<'a>

Must return a DOT compatible identifier naming the graph.

fn node_id(&'a self, n: &Node) -> Id<'a>

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

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

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

fn node_label(&'a self, n: &Node) -> LabelText<'a>

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.

fn edge_label(&'a self, e: &Edge<'a>) -> 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.

fn edge_style(&'a self, e: &Edge<'a>) -> Style

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

fn node_style(&'a self, _n: &N) -> Style

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

fn node_color(&'a self, _node: &N) -> Option<LabelText<'a>>

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

fn edge_end_arrow(&'a self, _e: &E) -> Arrow

Maps e to arrow style that will be used on the end of an edge. Defaults to default arrow style.

fn edge_start_arrow(&'a self, _e: &E) -> Arrow

Maps e to arrow style that will be used on the end of an edge. Defaults to default arrow style.

fn edge_color(&'a self, _e: &E) -> Option<LabelText<'a>>

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

fn kind(&self) -> Kind

The kind of graph, defaults to Kind::Digraph.
