Struct FactorGraphModel 

pub struct FactorGraphModel {
    pub variables: Vec<VizVariableNode>,
    pub factors: Vec<VizFactorNode>,
}

A lightweight factor graph representation for visualization.

This is intentionally decoupled from FactorGraph so that callers can build ad-hoc models (e.g. from external data) and still use the rendering / statistics helpers.

Fields

variables: Vec<VizVariableNode>

Variable nodes.

factors: Vec<VizFactorNode>

Factor nodes.

Implementations

impl FactorGraphModel

pub fn new() -> Self

Create a new, empty model.

pub fn from_factor_graph(fg: &FactorGraph) -> Self

Build a FactorGraphModel from an existing FactorGraph.

Variable ordering is arbitrary (HashMap iteration order).

pub fn add_variable( &mut self, name: impl Into<String>, domain_size: usize, ) -> usize

Add a variable node. Returns the index of the newly added variable.

pub fn add_factor( &mut self, name: impl Into<String>, variable_indices: Vec<usize>, )

Add a factor node connecting the given variable indices.

pub fn variable_count(&self) -> usize

Number of variable nodes.

pub fn factor_count(&self) -> usize

Number of factor nodes.

pub fn edge_count(&self) -> usize

Total number of edges (factor-variable connections).

Trait Implementations

impl Clone for FactorGraphModel

fn clone(&self) -> FactorGraphModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactorGraphModel

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

Formats the value using the given formatter.

impl Default for FactorGraphModel

fn default() -> FactorGraphModel

Returns the “default value” for a type.
