//! ## 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 dynamic queries.
//!
//! 3. Testable
//!
//! Use mock connections and/or SQLite to write tests for your application logic.
//!
//! 4. Service Oriented
//!
//! Quickly build services that join, filter, sort and paginate data in REST, GraphQL and gRPC 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)]
//! # pub id: i32,
//! # pub name: String,
//! # pub cake_id: Option<i32>,
//! # }
//! # #[derive(Copy, Clone, Debug, EnumIter, DeriveRelation)]
//! # pub enum Relation {
//! # #[sea_orm(
//! # belongs_to = "super::cake::Entity",
//! # from = "Column::CakeId",
//! # to = "super::cake::Column::Id"
//! # )]
//! # Cake,
//! # }
//! # impl Related<super::cake::Entity> for Entity {
//! # fn to() -> RelationDef {
//! # Relation::Cake.def()
//! # }
//! # }
//! # impl ActiveModelBehavior for ActiveModel {}
//! # }
//! # mod cake {
//! use sea_orm::entity::prelude::*;
//!
//! #[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
//! #[sea_orm(table_name = "cake")]
//! pub struct Model {
//! #[sea_orm(primary_key)]
//! pub id: i32,
//! pub name: String,
//! }
//!
//! #[derive(Copy, Clone, Debug, EnumIter, DeriveRelation)]
//! pub enum Relation {
//! #[sea_orm(has_many = "super::fruit::Entity")]
//! Fruit,
//! }
//!
//! impl Related<super::fruit::Entity> for Entity {
//! fn to() -> RelationDef {
//! Relation::Fruit.def()
//! }
//! }
//! # impl ActiveModelBehavior for ActiveModel {}
//! # }
//! # }
//! ```
//!
//! ### 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 pear = pear.insert(db).await?;
//! # Ok(())
//! # }
//! # async fn function2(db: &DbConn) -> Result<(), DbErr> {
//! # let apple = fruit::ActiveModel {

//! # ..Default::default() // no need to set primary key
//! # };
//! # let pear = fruit::ActiveModel {
//! # name: Set("Pear".to_owned()),
//! # ..Default::default()
//! # };
//!
//! // insert many
//! Fruit::insert_many([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::Model = pear.update(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: NotSet,
//! name: Set("Banana".to_owned()),
//! ..Default::default()
//! };
//!
//! // create, because primary key `id` is `NotSet`
//! 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> {
//! // delete one
//! let orange: Option<fruit::Model> = Fruit::find_by_id(1).one(db).await?;
//! let orange: fruit::Model = orange.unwrap();
//! fruit::Entity::delete(orange.into_active_model())
//! .exec(db)
//! .await?;
//!
//! // or simply
//! let orange: Option<fruit::Model> = Fruit::find_by_id(1).one(db).await?;
//! let orange: fruit::Model = orange.unwrap();
//! 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(())
//! # }
//! ```
