Rustorm is an SQL-centered ORM with focus on ease of use on conversion of database types to their appropriate rust type.

Selecting records

use rustorm::{
    DbError,
    FromDao,
    Pool,
    ToColumnNames,
    ToTableName,
};

#[derive(Debug, FromDao, ToColumnNames, ToTableName)]
struct Actor {
    actor_id: i32,
    first_name: String,
}

#[cfg(any(feature="with-postgres", feature = "with-sqlite"))]
fn main() {
    let mut pool = Pool::new();
    #[cfg(feature = "with-sqlite")]
    let db_url = "sqlite://sakila.db";
    #[cfg(feature = "with-postgres")]
    let db_url = "postgres://postgres:p0stgr3s@localhost/sakila";
    let em = pool.em(db_url).unwrap();
    let sql = "SELECT * FROM actor LIMIT 10";
    let actors: Result<Vec<Actor>, DbError> =
        em.execute_sql_with_return(sql, &[]);
    println!("Actor: {:#?}", actors);
    let actors = actors.unwrap();
    assert_eq!(actors.len(), 10);
    for actor in actors {
        println!("actor: {:?}", actor);
    }
}
#[cfg(feature="with-mysql")]
fn main() {
   println!("see examples for mysql usage, mysql has a little difference in the api");
}

Inserting and displaying the inserted records

use chrono::{
    offset::Utc,
    DateTime,
    NaiveDate,
};
use rustorm::{
    DbError,
    FromDao,
    Pool,
    TableName,
    ToColumnNames,
    ToDao,
    ToTableName,
};


#[cfg(any(feature="with-postgres", feature = "with-sqlite"))]
fn main() {
    mod for_insert {
        use super::*;
        #[derive(Debug, PartialEq, ToDao, ToColumnNames, ToTableName)]
        pub struct Actor {
            pub first_name: String,
            pub last_name: String,
        }
    }

    mod for_retrieve {
        use super::*;
        #[derive(Debug, FromDao, ToColumnNames, ToTableName)]
        pub struct Actor {
            pub actor_id: i32,
            pub first_name: String,
            pub last_name: String,
            pub last_update: DateTime<Utc>,
        }
    }

    let mut pool = Pool::new();
    #[cfg(feature = "with-sqlite")]
    let db_url = "sqlite://sakila.db";
    #[cfg(feature = "with-postgres")]
    let db_url = "postgres://postgres:p0stgr3s@localhost/sakila";
    let em = pool.em(db_url).unwrap();
    let tom_cruise = for_insert::Actor {
        first_name: "TOM".into(),
        last_name: "CRUISE".to_string(),
    };
    let tom_hanks = for_insert::Actor {
        first_name: "TOM".into(),
        last_name: "HANKS".to_string(),
    };

    let actors: Result<Vec<for_retrieve::Actor>, DbError> =
        em.insert(&[&tom_cruise, &tom_hanks]);
    println!("Actor: {:#?}", actors);
    assert!(actors.is_ok());
    let actors = actors.unwrap();
    let today = Utc::now().date();
    assert_eq!(tom_cruise.first_name, actors[0].first_name);
    assert_eq!(tom_cruise.last_name, actors[0].last_name);
    assert_eq!(today, actors[0].last_update.date());

    assert_eq!(tom_hanks.first_name, actors[1].first_name);
    assert_eq!(tom_hanks.last_name, actors[1].last_name);
    assert_eq!(today, actors[1].last_update.date());
}
#[cfg(feature="with-mysql")]
fn main() {
   println!("see examples for mysql usage, mysql has a little difference in the api");
}
