Struct CfgDot

pub struct CfgDot {
    pub config: CfgDotConfig,
}

The main struct for rendering DOT graphs.

Fields

config: CfgDotConfig

The configuration for rendering the graph.

Implementations

impl CfgDot

pub fn render<R, N, E>(&self, graph: &DiGraph<N, E>, resolver: &R) -> String

where R: NodeResolver,

Renders the DOT representation of a DiGraph using the provided resolver.

This method:

• Defines a directed graph (digraph CFG).
• Applies graph-level and node-level styles from self.config.
• Iterates over each node in the graph, resolving it via resolver.
• Calculates the number of incoming edges for each node to create “ports” for the edges.
• Constructs an HTML-like table label for each node with indentation to make it readable.
• Iterates over all edges and connects them to the correct node ports.

The data.render_node(8) call uses an indentation of 8 spaces for the node’s content.

Type Parameters

• R - A type that implements NodeResolver.
• N - Node weight type of the DiGraph.
• E - Edge weight type of the DiGraph.

Arguments

• graph - The directed graph to render.
• resolver - An object that resolves each node index to a data structure that can be rendered.

Returns

A String containing the entire DOT (Graphviz) representation of the graph.
