BookThis crate provides the #[ergol] macro. It allows to persist the data in a
database. For example, you just have to write
```rust use ergol::prelude::*;
pub struct User {
#[id] pub id: i32,
#[unique] pub username: String,
pub password: String,
pub age: Option
and the #[ergol] macro will generate most of the code you will need. You'll
then be able to run code like the following:
```rust // Drop the user table if it exists User::drop_table().execute(&client).await.ok();
// Create the user table User::create_table().execute(&client).await?;
// Create a user and save it into the database let mut user: User = User::create("thomas", "pa$$w0rd", Some(28)).save(&client).await?;
// Change some of its fields *user.age.as_mut().unwrap() += 1;
// Update the user in the database user.save(&client).await?;
// Fetch a user by its username thanks to the unique attribute
let user: Option
// Select all users
let users: Vec
