Backend Module for GeekORM

Example:

Here is an example of how to use GeekORM with a mock connection.

use geekorm::prelude::*;


#[derive(Table, Debug, Clone, Default, serde::Serialize, serde::Deserialize)]
pub struct Users {
    #[geekorm(primary_key, auto_increment)]
    pub id: PrimaryKey<i32>,
    #[geekorm(unique)]
    pub username: String,
}

#[tokio::main]
async fn main() -> Result<()> {
    // Create a new connection (this is a mock connection)
    let connection = Connection {};

    Users::create_table(&connection).await?;

    let users = vec!["geekmasher", "bob", "alice", "eve", "mallory", "trent"];
    for user in users {
        let mut new_user = Users::new(user);
        new_user.save(&connection).await?;
    }

    // Fetch or create a user
    let mut geek = Users::new("geekmasher");
    geek.fetch_or_create(&connection).await?;
     
    // Fetch a user by their username (exact match)
    let geekmasher = Users::fetch_by_username(&connection, "geekmasher").await?;

    // Search for a user (partial match)
    let search = Users::search(&connection, "geek").await?;

    // Fetch first and last user
    let first_user = Users::first(&connection).await?;
    let last_user = Users::last(&connection).await?;

    // Delete the user
    geek.delete(&connection).await?;

    Ok(())
}

Traits

• GeekConnection
  GeekConnection is the trait that all backends must implement to be able to interact with the database.
• GeekConnector
  GeekConnection is the trait used for models to interact with the database.
