# Premix ORM
Premix ORM is a zero-overhead, type-safe ORM for Rust, designed for performance and developer experience.
This crate (`premix-orm`) is the official facade that re-exports `premix-core` and `premix-macros`, providing a unified entry point for your application.
## Why use this facade?
Previously, users had to manage both `premix-core` and `premix-macros`. With `premix-orm`, you get:
1. Unified imports: `use premix_orm::prelude::*;` gets you everything.
2. No version mismatch: core and macros versions stay compatible.
3. Clean dependencies: only one crate to add to your `Cargo.toml`.
## Installation
Add this to your `Cargo.toml`:
```toml
[dependencies]
premix-orm = "1.0.3"
sqlx = { version = "0.8", features = ["runtime-tokio", "sqlite"] }
tokio = { version = "1", features = ["full"] }
serde = { version = "1", features = ["derive"] }
```
## Database Features
Enable database features on both `premix-orm` and `sqlx`:
```toml
premix-orm = { version = "1.0.3", features = ["postgres"] }
sqlx = { version = "0.8", features = ["runtime-tokio", "sqlite", "postgres"] }
```
## Quick Start
```rust
use premix_orm::prelude::*;
use serde::{Deserialize, Serialize};
#[derive(Model, Debug, Serialize, Deserialize)]
pub struct User {
pub id: i32,
pub name: String,
// Soft delete is auto-detected by field name.
pub deleted_at: Option<chrono::DateTime<chrono::Utc>>,
}
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let pool = SqlitePool::connect("sqlite::memory:").await?;
// Sync schema.
Premix::sync::<User, _>(&pool).await?;
// CRUD.
let mut user = User { id: 0, name: "Alice".to_string(), deleted_at: None };
user.save(&pool).await?;
println!("Saved user with ID: {}", user.id);
Ok(())
}
```
## Book
For a longer-form guide, see `orm-book/` in this repository.
## SQL Transparency
Inspect the SQL generated by the query builder:
```rust
let query = User::find_in_pool(&pool).filter("age > 18").limit(10);
println!("{}", query.to_sql());
```
## Raw SQL Escape Hatch
Run raw SQL while mapping results to your model:
```rust
let users = User::raw_sql("SELECT * FROM users WHERE active = 1")
.fetch_all(&pool)
.await?;
```
