# The Toql derive
The recommended way to use Toql in your project is to use the Toql derive.

The derive builds a lot of code. This includes

- Mapping of struct fields to Toql fields and database.
- Creating query builder functions.
- Handling relationships through joins and merges.
- Creating high level functions to load, insert, update and delete structs.


## Example

With this simple code

 ```rust
	#[derive(Toql)]
	struct User {
		id: u32,
		name: String,
}
```

we can now do the following

```rust
use toql::mysql::load_one; // Load function from derive
use toql::mysql::update_one; // Update function from derive

let conn = --snip--
let cache = SqlMapperCache::new();
SqlMapper::insert_new_mapper::<User>(&mut cache); // Mapper function from derive

let q = Query::wildcard().and(User::fields.id().eq(5)); // Builder fields from derive
let user = load_one<User>(&q, &cache, &mut conn); 

user.age = Some(16);
update_one(&user); 
```
