Struct CodeGraph 

pub struct CodeGraph { /* private fields */ }

The core in-memory graph of code units and their relationships.

Units are stored by their sequential ID. Edges are indexed by source ID for efficient forward traversal.

Implementations

impl CodeGraph

pub fn new(dimension: usize) -> Self

Create a new empty code graph with the given feature vector dimension.

pub fn with_default_dimension() -> Self

Create with default dimension (256).

pub fn add_unit(&mut self, unit: CodeUnit) -> u64

Add a code unit to the graph, assigning it a sequential ID.

Returns the assigned ID.

pub fn add_edge(&mut self, edge: Edge) -> AcbResult<()>

Add an edge between two code units.

Errors

• AcbError::SelfEdge if source and target are the same.
• AcbError::UnitNotFound if source or target don’t exist.
• AcbError::TooManyEdges if the source unit already has too many edges.

pub fn unit_count(&self) -> usize

Returns the number of code units.

pub fn edge_count(&self) -> usize

Returns the number of edges.

pub fn dimension(&self) -> usize

Returns the feature vector dimension.

pub fn languages(&self) -> &HashSet<Language>

Returns the set of languages in the graph.

pub fn get_unit(&self, id: u64) -> Option<&CodeUnit>

Get a code unit by ID.

pub fn get_unit_mut(&mut self, id: u64) -> Option<&mut CodeUnit>

Get a mutable reference to a code unit by ID.

pub fn units(&self) -> &[CodeUnit]

Iterate over all code units.

pub fn edges(&self) -> &[Edge]

Iterate over all edges.

pub fn edges_from(&self, source_id: u64) -> Vec<&Edge>

Get all edges originating from the given unit.

pub fn edges_to(&self, target_id: u64) -> Vec<&Edge>

Get all edges targeting the given unit.

pub fn edges_from_of_type( &self, source_id: u64, edge_type: EdgeType, ) -> Vec<&Edge>

Get edges from a source filtered by edge type.

pub fn edges_to_of_type( &self, target_id: u64, edge_type: EdgeType, ) -> Vec<&Edge>

Get edges to a target filtered by edge type.

pub fn find_units_by_name(&self, prefix: &str) -> Vec<&CodeUnit>

Find units by name (case-insensitive prefix match).

pub fn find_units_by_exact_name(&self, name: &str) -> Vec<&CodeUnit>

Find units by exact name.

pub fn find_units_by_type(&self, unit_type: CodeUnitType) -> Vec<&CodeUnit>

Find units by type.

pub fn find_units_by_language(&self, language: Language) -> Vec<&CodeUnit>

Find units by language.

pub fn find_units_by_path(&self, path: &Path) -> Vec<&CodeUnit>

Find units in a specific file.

pub fn has_edge( &self, source_id: u64, target_id: u64, edge_type: EdgeType, ) -> bool

Check if an edge between two units of a given type already exists.

pub fn stats(&self) -> GraphStats

Get summary statistics about the graph.
