Implementations

impl ComputationGraph

pub fn new() -> Self

Create a new empty computation graph

pub fn add_node(&mut self, node: GraphNode) -> Result<(), GraphError>

Add a node to the graph

pub fn mark_input(&mut self, node_id: String)

Mark a node as an input

pub fn mark_output(&mut self, node_id: String)

Mark a node as an output

pub fn topological_sort(&self) -> Result<Vec<String>, GraphError>

Get topological order of nodes

pub fn extract_subgraph( &self, output_ids: &[String], ) -> Result<ComputationGraph, GraphError>

Extract a subgraph containing only the specified output nodes

pub fn optimize_cse(&mut self) -> usize

Optimize the graph using common subexpression elimination

pub fn node_count(&self) -> usize

Count the number of nodes

pub fn input_count(&self) -> usize

Get the number of inputs

pub fn output_count(&self) -> usize
