Crate keradb_sdk 

KeraDB Rust SDK

A MongoDB-compatible Rust client for KeraDB — a lightweight, embedded NoSQL document database with advanced vector search capabilities.

Usage

use keradb_sdk::*;
use serde_json::json;

// Open / create a database
let mut client = connect("mydb.ndb").unwrap();
let db = client.database();
let users = db.collection("users");

// Insert
let result = users.insert_one(json!({"name": "Alice", "age": 30})).unwrap();
println!("Inserted: {}", result.inserted_id);

// Find
let doc = users.find_one(Some(&json!({"_id": result.inserted_id}))).unwrap();
println!("Found: {:?}", doc);

// Update
users.update_one(
    &json!({"_id": result.inserted_id}),
    &json!({"$set": {"age": 31}}),
).unwrap();

// Delete
users.delete_one(&json!({"_id": result.inserted_id})).unwrap();

client.close();

Vector search

use keradb_sdk::*;

let mut client = connect("vectors.ndb").unwrap();

let config = VectorConfig::new(128)
    .with_distance(Distance::Cosine)
    .with_m(16)
    .with_ef_construction(200);

client.create_vector_collection("embeddings", &config).unwrap();

let embedding: Vec<f32> = (0..128).map(|i| i as f32 / 128.0).collect();
let id = client.insert_vector("embeddings", &embedding, None).unwrap();

let results = client.vector_search("embeddings", &embedding, 5).unwrap();
for r in results {
    println!("{}", r);
}

client.close();
