In the test and docs example, I use scylla crate it seems to be the best and most maintained crate to use Cassandra in Rust. There are other crates but they appear to be unmaintained.

👋 @DDtKey @barsdeveloper were there any blockers to merge this one? I'm looking to build a rust app with a similar setup and this would really help me test.

No, I just didn't have a bandwidth to take a look

Will do soon!

Hi, You can very easily do it without this specific image. Look how I initialize my test here:
https://github.com/TankHQ/tank/blob/master/tank-scylladb/tests/init.rs#L136

    let mut image = GenericImage::new("cassandra", "5.0.6")
        .with_startup_timeout(Duration::from_secs(120))
        .with_log_consumer(TestcontainersLogConsumer)
        .with_mapped_port(9042, ContainerPort::Tcp(9042))
        .with_ready_conditions(vec![WaitFor::message_on_either_std("Startup complete")]);

SSL on Cassandra I didn't manage to make it work, please ignore all the encryption specific settings.
