List, Set, Map

List

List is represented as Vec<T>

#![allow(unused)]
fn main() {
extern crate scylla;
use scylla::Session;
use std::error::Error;
async fn check_only_compiles(session: &Session) -> Result<(), Box<dyn Error>> {

session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (&to_insert,))
    .await?;

        let (list_value,): (Vec<i32>,) = row?;
    }
}
Ok(())
}
}

Set

Set is represented as Vec<T>

#![allow(unused)]

    }
}
Ok(())
}
}

Map

Map is represented as std::collections::HashMap<K, V>

#![allow(unused)]
fn main() {

session
    .query("INSERT INTO keyspace.table (a) VALUES(?)", (&to_insert,))
    .await?;

// Read a map from the table
if let Some(rows) = session.query("SELECT a FROM keyspace.table", &[]).await?.rows {
    for row in rows.into_typed::<(HashMap<String, i32>,)>() {

Ok(())
