erio-context-store

erio-context-store provides vector-backed context storage and semantic retrieval APIs for retrieval-augmented workflows.

It handles indexing, persistence configuration, and top-k search over embedded content.

Quickstart

use std::path::PathBuf;
use std::sync::Arc;

use erio_context_store::{ContextConfig, ContextStore, HnswConfig};
use erio_embedding::{EmbeddingConfig, EmbeddingEngine, GemmaEmbedding};

async fn run() -> Result<(), Box<dyn std::error::Error>> {
    let embedding: Arc<dyn EmbeddingEngine> =
        Arc::new(GemmaEmbedding::new(EmbeddingConfig::default())?);

    let config = ContextConfig {
        path: PathBuf::from("/tmp/erio-context-store"),
        index: HnswConfig::default(),
    };

    let store = ContextStore::new(config, embedding).await?;
    let _results = store.search("what is erio?", 5, None).await?;
    Ok(())
}
