//! This module contains all functionality that is needed to implement mutations
//!
//! In general mutations should just work without any additional work that
//! writing some struct definition and deriving basic diesel for them
//! For special cases a manual implementation of one of the for exported traits
//! is required
//!
//! # Insert
//!
//! The easiest way to provide a single table insert mutation is to crate a struct
//! with all corresponding fields that derive `#[derive(Insertable, GrahpQLInputobject)]`
//! ```rust
//! # #[macro_use]
//! # extern crate diesel;
//! # #[macro_use]
//! # extern crate juniper;
//! # table! {
//! # heros {
//! # id -> Integer,
//! # name -> Text,
//! # species -> Nullable<Integer>,
//! # home_world -> Nullable<Integer>,
//! # }
//! # }
//!
//! #[derive(Insertable, GraphQLInputObject, Clone, Debug)]
//! #[table_name = "heros"]
//! pub struct NewHero {
//! name: String,
//! species: i32,
//! home_world: Option<i32>,
//! }
//! # fn main() {}
//! ```
//!
//! For more complex cases like inserts that involve multiple tables at one
//! implement [`HandleInsert`](trait.HandleInsert.html) and
//! [`InsertHelper`](trait.InsertHelper.html) manually
//!
//! # Update
//!
//! Similar to `Insert` operations the easiest way to provide a single table update
//! mutation is to create a struct with all corresponding fields that derive
//! `#[derive(AsChangeset, GraphqlInputObject, Identifiable)]`
//! ```rust
//! # #[macro_use]
//! # extern crate diesel;
//! # #[macro_use]
//! # extern crate juniper;
//! # table! {
//! # heros {
//! # id -> Integer,
//! # name -> Text,
//! # species -> Nullable<Integer>,
//! # home_world -> Nullable<Integer>,
//! # }
//! # }
//!
//! #[derive(AsChangeset, GraphQLInputObject, Identifiable, Debug)]
//! #[table_name = "heros"]
//! pub struct HeroChangeset {
//! id: i32,
//! name: Option<String>,
//! species: Option<i32>,
//! home_world: Option<i32>,
//! }
//! # fn main() {}
//! ```
