Struct RotaryMemoryBridge 

pub struct RotaryMemoryBridge { /* private fields */ }

Bridge that wraps rx4’s GraphMemory for agent memory (concepts, decisions, patterns, bugs) while keeping apollo’s SurrealDB for channel state, swarm coordination, and cron scheduling.

rx4’s GraphMemory is an in-memory knowledge graph with PageRank, community detection, and JSON persistence. It does not require SQLite (unlike rx4’s MemoryStore which uses rusqlite 0.37).

This bridge provides:

• Graph-based agent memory via rx4::GraphMemory (concepts, decisions, patterns)
• Conversation extraction via rx4::ConversationExtractor
• JSON persistence for the graph

TODO: Enable rx4’s memory feature to also get SQLite FTS5 full-text search via rx4::MemoryStore. For now, apollo’s SurrealDB backend remains the primary persistent memory for conversation history and key-value store.

Implementations

impl RotaryMemoryBridge

pub fn new(workspace: &Path) -> Self

Create a new memory bridge rooted at the given workspace.

pub fn empty() -> Self

Create a new memory bridge with an empty graph (no workspace).

pub fn extract_conversation( &mut self, conversation: &[ConversationTurn], ) -> ExtractionResult

Extract memory nodes and edges from a conversation and add them to the graph.

This uses rx4’s ConversationExtractor to identify concepts, decisions, and patterns from the conversation, then adds them as nodes in the GraphMemory.

pub fn search(&self, query: &str) -> Vec<&GraphMemoryNode>

Search the graph memory for nodes matching the query.

pub fn pagerank(&self) -> Vec<(String, f64)>

Get PageRank scores for all nodes (identifies the most important concepts/decisions in the agent’s memory).

pub fn stats(&self) -> GraphStats

Get graph statistics (node count, edge count, etc.)

pub fn save(&self) -> Result<(), GraphMemoryError>

Save the graph to disk (JSON format).

pub fn load(&mut self) -> Result<(), GraphMemoryError>

Load the graph from disk (JSON format).

pub fn graph(&self) -> &GraphMemory

Get a reference to the inner GraphMemory.

pub fn graph_mut(&mut self) -> &mut GraphMemory

Get a mutable reference to the inner GraphMemory.
