Crate klieo_memory_neo4j 

Neo4j-backed implementations of the memory traits in klieo_core::memory.

MemoryNeo4j::connect dials a Bolt endpoint, ensures schema constraints + indices, and returns trait-object handles ready to drop into klieo_core::AgentContext. Reach for MemoryNeo4j::new only when you need a tuned Neo4jConfig (custom max_connections, fetch_size, etc.) — see ADR-036.

Example

use klieo_memory_neo4j::MemoryNeo4j;

async fn example() {
    let mem = MemoryNeo4j::connect(
        "bolt://127.0.0.1:7687",
        "neo4j",
        "secret",
    )
    .await
    .unwrap();
    let _ = mem;
}

Advanced wiring — tuned Neo4jConfig

use klieo_memory_neo4j::{MemoryNeo4j, Neo4jConfig};

async fn example() {
    let cfg = Neo4jConfig::new("bolt://127.0.0.1:7687", "neo4j", "secret");
    let mem = MemoryNeo4j::new(cfg).await.unwrap();
    let _ = mem;
}

What’s implemented

Trait	Module	Notes
ShortTermMemory	short_term	(:Thread)-[:HAS_MESSAGE]->(:Message) ordered by seq.
EpisodicMemory	episodic	(:Run)-[:RECORDED]->(:Episode) ordered by seq.

LongTermMemory is intentionally not implemented here — see klieo-memory-qdrant for vector recall.
