//! **cdrs** is a native Cassandra DB client written in Rust.
//!
//! ## Getting started
//!
//! This example configures a cluster consisting of a single node, and uses round-robin load balancing.
//!
//! ```no_run
//! use cdrs_tokio::cluster::session::{TcpSessionBuilder, SessionBuilder};
//! use cdrs_tokio::cluster::NodeTcpConfigBuilder;
//! use cdrs_tokio::load_balancing::RoundRobinLoadBalancingStrategy;
//! use std::sync::Arc;
//!
//! #[tokio::main]
//! async fn main() {
//!     let cluster_config = NodeTcpConfigBuilder::new()
//!         .with_contact_point("127.0.0.1:9042".into())
//!         .build()
//!         .await
//!         .unwrap();
//!     let session = TcpSessionBuilder::new(RoundRobinLoadBalancingStrategy::new(), cluster_config)
//!         .build()
//!         .await
//!         .unwrap();
//!
//!     let create_ks = "CREATE KEYSPACE IF NOT EXISTS test_ks WITH REPLICATION = { \
//!                      'class' : 'SimpleStrategy', 'replication_factor' : 1 };";
//!     session
//!         .query(create_ks)
//!         .await
//!         .expect("Keyspace create error");
//! }
//! ```
//!
//! ## Nodes and load balancing
//!
//! In order to maximize efficiency, the driver needs to be appropriately configured for given use
//! case. Please look at available [load balancers](crate::load_balancing) and
//! [node distance evaluators](crate::load_balancing::node_distance_evaluator) to pick the optimal
//! solution when building the [`Session`](crate::cluster::session::Session). Topology-aware load
//! balancing is preferred when dealing with multi-node clusters, otherwise simpler strategies might
//! prove more efficient.
