Crate bottle_orm 

Bottle ORM

Bottle ORM is a lightweight, async ORM for Rust built on top of sqlx. It is designed to be simple, efficient, and easy to use, providing a fluent Query Builder and automatic schema migrations.

Features

• Async & Non-blocking: Built on tokio and sqlx
• Multi-Driver Support: Compatible with PostgreSQL, MySQL, and SQLite (via sqlx::Any)
• Macro-based Models: Define your schema using standard Rust structs with #[derive(Model)]
• Fluent Query Builder: Chainable methods for filtering, selecting, pagination, and sorting
• Auto-Migration: Automatically creates tables and foreign key constraints based on your structs
• UUID Support: Full support for UUID versions 1 through 7

Quick Start Example

use bottle_orm::{Database, Model};
use serde::{Deserialize, Serialize};
use sqlx::FromRow;

#[derive(Model, Debug, Clone, Serialize, Deserialize, FromRow)]
struct User {
    #[orm(primary_key)]
    id: i32,
    #[orm(size = 50, unique)]
    username: String,
    age: i32,
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let db = Database::connect("sqlite::memory:").await?;

    db.migrator()
        .register::<User>()
        .run()
        .await?;

    let users: Vec<User> = db.model::<User>()
        .filter("age", ">=", 18)
        .scan()
        .await?;

    Ok(())
}
