hippmem-engine

HIPPMEM native association memory engine — the unified public Rust API orchestration layer, plus the hippmem CLI and hippmem-server gRPC server.

This is the crate most users want. It wires together the write path, retrieval path, and consolidation into a single Engine with seven public methods.

Part of HIPPMEM — a native associative memory engine for AI agents, written in Rust.

Quick start

cargo add hippmem-engine

use hippmem_engine::Engine;

let engine = Engine::open(config)?;
engine.write(WriteMemoryInput { content: "The user prefers Rust.".into(), ..Default::default() })?;
let results = engine.retrieve(RetrieveInput { query: "what does the user prefer?".into(), k: 3, ..Default::default() })?;

Runs fully offline with the deterministic fallback backend — no GPU, API key, or network required.
