qail-qdrant

QAIL driver for Qdrant vector database.

⚠️ BETA - This crate is under active development. API may change.

Overview

AST-native Rust driver for Qdrant vector search. Uses the same QAIL builder pattern as qail-pg, encoding directly to Qdrant REST payload bytes.

This crate does not use SQL. "SQL bytes vs SQL strings" terminology only applies to PostgreSQL crates (qail-core + qail-pg).

Features

• 🔍 Vector similarity search with filters
• 📦 Upsert points with payload metadata
• 🗑️ Delete points by ID
• 📁 Collection management (create, delete, list)
• 🚀 Zero-copy encoding to JSON

Quick Start

use qail_qdrant::{QdrantDriver, Point, Distance};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Connect
    let driver = QdrantDriver::connect("localhost", 6333).await?;

    // Create collection
    driver.create_collection("products", 384, Distance::Cosine).await?;

    // Upsert points
    driver.upsert("products", &[
        Point::new("p1", vec![0.1, 0.2, 0.3, /* ... */])
            .with_payload("name", "iPhone 15"),
    ]).await?;

    // Search
    let embedding = vec![0.1, 0.2, 0.3, /* ... */];
    let results = driver.search(&Qail::search("products")
        .vector(embedding)
        .limit(10)
    ).await?;

    Ok(())
}

Requirements

• Qdrant server running (default port: 6333)
• Rust 2024 edition
