|
|

|
|
//! #### SeaORM is a relational ORM to help you build light weight and concurrent web services in Rust.

|
|
//! ## Features
|
|
//!
|
|
//! 1. Async
|
|
//!
|
|
//! Relying on [SQLx](https://github.com/launchbadge/sqlx), SeaORM is a new library with async support from day 1.
|
|
//!
|
|
//! 2. Dynamic
|
|
//!
|
|
//! Built upon [SeaQuery](https://github.com/SeaQL/sea-query), SeaORM allows you to build complex queries without 'fighting the ORM'.
|
|
//!
|
|
//! 3. Testable
|
|
//!
|
|
//! Use mock connections to write unit tests for your logic.
|
|
//!
|
|
//! 4. Service Oriented
|
|
//!
|
|
//! Quickly build services that join, filter, sort and paginate data in APIs.
|
|
//!
|
|
//! ## A quick taste of SeaORM
|
|
//!
|
|
//! ### Entity
|
|
//! ```
|
|
//! # #[cfg(feature = "macros")]
|
|
//! # mod entities {
|
|
//! # mod fruit {
|
|
//! # use sea_orm::entity::prelude::*;

|
//! # #[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
|
|
//! # #[sea_orm(table_name = "fruit")]
|
|
//! # pub struct Model {
|
|
//! # #[sea_orm(primary_key)]
