Struct GraphManager 

pub struct GraphManager { /* private fields */ }

Owns a CsrGraph and provides high-level graph operations.

All methods take &self — internal RwLock handles concurrency.

Implementations

impl GraphManager

pub fn new() -> Self

Creates a new in-memory graph manager (no durability log).

pub fn open(dir: &Path) -> MenteResult<Self>

Open a directory-backed graph manager.

Loads the last snapshot (graph.json) if present, replays the edge log (edges.jsonl) on top of it, and keeps the log open for appending, so graph mutations are crash-durable between snapshots.

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

Save a graph snapshot to the given directory and truncate the edge log.

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

Load the graph snapshot from the given directory (no durability log).

Prefer open(), which also replays and maintains the edge log.

pub fn add_memory(&self, id: MemoryId)

Register a memory node in the graph.

pub fn remove_memory(&self, id: MemoryId)

Remove a memory node and all its edges.

pub fn add_relationship(&self, edge: &MemoryEdge) -> MenteResult<()>

Add a relationship (edge) between two memory nodes.

pub fn get_context_subgraph( &self, center: MemoryId, depth: usize, ) -> (Vec<MemoryId>, Vec<MemoryEdge>)

Extract a context subgraph around a center node.

pub fn propagate_belief_change( &self, id: MemoryId, new_confidence: f32, ) -> Vec<(MemoryId, f32)>

Propagate a confidence change through the graph.

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

Find all nodes that contradict the given node.

pub fn compact(&self)

Merge the delta log into CSR/CSC compressed storage.

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

Strengthen an edge weight (Hebbian learning: neurons that fire together wire together).

pub fn read_graph(&self) -> RwLockReadGuard<'_, CsrGraph>

Access the underlying graph for read-only traversals.

Returns a read guard — hold it only briefly to avoid blocking writers.

pub fn graph(&self) -> RwLockReadGuard<'_, CsrGraph>

Alias for read_graph() — backward compatible access to the CsrGraph.

Trait Implementations

impl Default for GraphManager

fn default() -> Self

Returns the “default value” for a type.
