//! # SeaORM
//!
//! SeaORM is a relational ORM to help you build light weight and concurrent web services in Rust.
//!
//! [![Getting Started](https://img.shields.io/badge/Getting%20Started-blue)](https://www.sea-ql.org/SeaORM/docs/index)
//! [![Examples](https://img.shields.io/badge/Examples-green)](https://github.com/SeaQL/sea-orm/tree/master/examples)

//!
//! ## 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
//!
//! ### Select
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};
//! # async fn function(db: &DbConn) -> Result<(), DbErr> {
//! // find all models
//! let cakes: Vec<cake::Model> = Cake::find().all(db).await?;
//!
//! // find and filter
//! let chocolate: Vec<cake::Model> = Cake::find()
//! .filter(cake::Column::Name.contains("chocolate"))
//! .all(db)
//! .await?;
//!
//! // find one model
//! let cheese: Option<cake::Model> = Cake::find_by_id(1).one(db).await?;
//! let cheese: cake::Model = cheese.unwrap();
//!
//! // find related models (lazy)
//! let fruits: Vec<fruit::Model> = cheese.find_related(Fruit).all(db).await?;
//!
//! // find related models (eager)
//! let cake_with_fruits: Vec<(cake::Model, Vec<fruit::Model>)> =
//! Cake::find().find_with_related(Fruit).all(db).await?;
//!
//! # Ok(())
//! # }
//! ```
//! ### Insert
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};
//! # async fn function(db: &DbConn) -> Result<(), DbErr> {
//! let apple = fruit::ActiveModel {
//! name: Set("Apple".to_owned()),
//! ..Default::default() // no need to set primary key
//! };
//!
//! let pear = fruit::ActiveModel {
//! name: Set("Pear".to_owned()),
//! ..Default::default()
//! };
//!
//! // insert one
//! let res = Fruit::insert(pear).exec(db).await?;
//!
//! println!("InsertResult: {}", res.last_insert_id);
//! # Ok(())
//! # }
//! # async fn function2(db: &DbConn) -> Result<(), DbErr> {
//! # let apple = fruit::ActiveModel {
//! # name: Set("Apple".to_owned()),
//! # ..Default::default() // no need to set primary key
//! # };
//! # let pear = fruit::ActiveModel {
//! # name: Set("Pear".to_owned()),
//! # ..Default::default()
//! # };
//!
//! // insert many
//! Fruit::insert_many(vec![apple, pear]).exec(db).await?;
//! # Ok(())
//! # }
//! ```
//! ### Update
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};
//! use sea_orm::sea_query::{Expr, Value};
//!
//! # async fn function(db: &DbConn) -> Result<(), DbErr> {
//! let pear: Option<fruit::Model> = Fruit::find_by_id(1).one(db).await?;
//! let mut pear: fruit::ActiveModel = pear.unwrap().into();
//!
//! pear.name = Set("Sweet pear".to_owned());
//!
//! // update one
//! let pear: fruit::ActiveModel = Fruit::update(pear).exec(db).await?;
//!
//! // update many: UPDATE "fruit" SET "cake_id" = NULL WHERE "fruit"."name" LIKE '%Apple%'
//! Fruit::update_many()
//! .col_expr(fruit::Column::CakeId, Expr::value(Value::Int(None)))
//! .filter(fruit::Column::Name.contains("Apple"))
//! .exec(db)
//! .await?;
//!
//! # Ok(())
//! # }
//! ```
//! ### Save
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};
//! # async fn function(db: &DbConn) -> Result<(), DbErr> {
//! let banana = fruit::ActiveModel {
//! id: Unset(None),
//! name: Set("Banana".to_owned()),
//! ..Default::default()
//! };
//!
//! // create, because primary key `id` is `Unset`
//! let mut banana = banana.save(db).await?;
//!
//! banana.name = Set("Banana Mongo".to_owned());
//!
//! // update, because primary key `id` is `Set`
//! let banana = banana.save(db).await?;
//!
//! # Ok(())
//! # }
//! ```
//! ### Delete
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};
//! # async fn function(db: &DbConn) -> Result<(), DbErr> {
//! let orange: Option<fruit::Model> = Fruit::find_by_id(1).one(db).await?;
//! let orange: fruit::ActiveModel = orange.unwrap().into();
//!
//! // delete one
//! fruit::Entity::delete(orange).exec(db).await?;
//! // or simply
//! # let orange: fruit::ActiveModel = Fruit::find_by_id(1).one(db).await.unwrap().unwrap().into();
//! orange.delete(db).await?;
//!
//! // delete many: DELETE FROM "fruit" WHERE "fruit"."name" LIKE 'Orange'
//! fruit::Entity::delete_many()
//! .filter(fruit::Column::Name.contains("Orange"))
//! .exec(db)
//! .await?;
//!
//! # Ok(())
//! # }
//! ```
