Struct CsrGraph 

pub struct CsrGraph { /* private fields */ }

Bidirectional graph with CSR (outgoing) and CSC (incoming) plus a delta log.

Implementations

impl CsrGraph

pub fn new() -> Self

Creates a new empty CSR graph.

pub fn add_node(&mut self, id: MemoryId) -> u32

Register a node. Returns its internal index.

pub fn remove_node(&mut self, id: MemoryId)

Remove a node and all its edges.

pub fn add_edge(&mut self, edge: &MemoryEdge)

Add an edge to the delta log.

Deduplicates: if a currently-valid edge with the same source, target, and type already exists (in CSR or the delta log), the graph is left unchanged. Write inference and pipeline passes may infer the same relationship more than once; parallel duplicates carry no information.

pub fn strengthen_edge( &mut self, source: MemoryId, target: MemoryId, delta: f32, )

Strengthen an edge by incrementing its weight (Hebbian learning).

Updates the existing edge rather than appending a parallel duplicate: a delta edge is bumped in place; a compressed (CSR) edge is marked removed and replaced with a delta override, so compaction keeps exactly one copy.

pub fn remove_edge(&mut self, source: MemoryId, target: MemoryId)

Mark an edge for removal.

pub fn outgoing(&self, id: MemoryId) -> Vec<(MemoryId, StoredEdge)>

Get all outgoing edges from a node (CSR + delta, minus removed).

pub fn outgoing_valid_at( &self, id: MemoryId, at: Timestamp, ) -> Vec<(MemoryId, StoredEdge)>

Get outgoing edges that are temporally valid at the given timestamp.

pub fn incoming(&self, id: MemoryId) -> Vec<(MemoryId, StoredEdge)>

Get all incoming edges to a node (CSC + delta, minus removed).

pub fn incoming_valid_at( &self, id: MemoryId, at: Timestamp, ) -> Vec<(MemoryId, StoredEdge)>

Get incoming edges that are temporally valid at the given timestamp.

pub fn contains_node(&self, id: MemoryId) -> bool

Check if a node exists in the graph.

pub fn node_count(&self) -> usize

Number of registered nodes.

pub fn node_ids(&self) -> &[MemoryId]

All registered node IDs.

pub fn compact(&mut self)

Merge all delta edges and removals into the compressed CSR/CSC storage.

pub fn save(&self, path: &Path) -> MenteResult<()>

Save the graph snapshot to a file.

pub fn load(path: &Path) -> MenteResult<Self>

Load the graph from a file.
