Creates a new factory to create a MongoDB database

Create mongodb database factory with standard environment variable for database url and database name

mongodb_macro::database!(DbFactory; DbFactoryOpts);

fn main() {
    std::env::set_var("MONGODB_HOST", "localhost");
    std::env::set_var("DB_URL", "mongodb://root:root@${MONGODB_HOST}:27017");
    std::env::set_var("DB_NAME", "test");
 
    let factory = DbFactory::parse();
 
    // let db = factory.create().await.expect("failed to connect");
 
    assert_eq!(&factory.config().db_url, "mongodb://root:root@localhost:27017");
}

Create mongodb database factory with specified environment variable for database url and database name

mongodb_macro::database!(DbFactory; DbFactoryOpts; ("MONGO_DB_URL", "MONGO_DB_NAME"));

fn main() {
    std::env::set_var("MONGODB_HOST", "localhost");
    std::env::set_var("MONGO_DB_URL", "mongodb://root:root@${MONGODB_HOST}:27017");
    std::env::set_var("MONGO_DB_NAME", "test");
 
    let factory = DbFactory::parse();

    // let db = factory.create().await.expect("failed to connect");
 
    assert_eq!(&factory.config().db_url, "mongodb://root:root@localhost:27017");
