BaraDB Rust Client

Official Rust client for BaraDB — a multimodal database engine written in Nim.

Features

• Binary wire protocol — fast TCP communication using only std
• Zero dependencies — no external crates required
• Sync API — blocking I/O suitable for most applications
• Query builder — fluent SQL construction
• Vector & JSON support — first-class multimodal types

Installation

Add to your Cargo.toml:

[dependencies]
baradb = "1.0"

Or from source:

git clone https://github.com/barabadb/baradadb.git
cd clients/rust
cargo build

Quick Start

use baradb::Client;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = Client::connect("localhost", 9472)?;
    let result = client.query("SELECT name, age FROM users WHERE age > 18")?;
    for row in result.rows() {
        println!("{:?}", row);
    }
    client.close();
    Ok(())
}

Parameterized Queries

use baradb::{Client, WireValue};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = Client::connect("localhost", 9472)?;
    let result = client.query_params(
        "SELECT * FROM users WHERE age > $1 AND country = $2",
        &[WireValue::Int64(18), WireValue::String("BG".to_string())],
    )?;
    for row in result.rows() {
        println!("{:?}", row);
    }
    client.close();
    Ok(())
}

Query Builder

use baradb::Client;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = Client::connect("localhost", 9472)?;
    let result = baradb::QueryBuilder::new(&mut client)
        .select(&["name", "email"])
        .from("users")
        .where_clause("active = true")
        .order_by("name", "ASC")
        .limit(10)
        .exec()?;
    for row in result.rows() {
        println!("{:?}", row);
    }
    client.close();
    Ok(())
}

Vector Search

use baradb::{Client, WireValue};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = Client::connect("localhost", 9472)?;
    let result = client.query_params(
        "SELECT id, name FROM products ORDER BY embedding <-> $1 LIMIT 5",
        &[WireValue::Vector(vec![0.1, 0.2, 0.3])],
    )?;
    client.close();
    Ok(())
}

Running Tests

Unit tests (no server):

cargo test --lib

Integration tests (requires server on localhost:9472):

# Start server
docker run -d -p 9472:9472 baradb:latest

# Run all tests
cargo test

API Reference

Client::connect(host, port)

Creates a new client connected to the given host and port.

Methods

• query(sql) -> Result<QueryResult> — execute SELECT-like query
• query_params(sql, params) -> Result<QueryResult> — parameterized query
• execute(sql) -> Result<usize> — execute DDL/DML, returns affected rows
• auth(token) -> Result<()> — JWT authentication
• ping() -> Result<bool> — health check
• close() — close connection
