//! ## 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)]

//!
//! #[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 {

//!     Cake::find().find_with_related(Fruit).all(db).await?;
//!
//! # Ok(())
//! # }
//! ```
//! ### Insert
//! ```
//! # use sea_orm::{DbConn, error::*, entity::*, query::*, tests_cfg::*};

//! # };
//!
//! // 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: 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()
