Features

• TCP/SSL connection;
• Load balancing;
• Connection pooling;
• LZ4, Snappy compression;
• Cassandra-to-Rust data deserialization;
• Pluggable authentication strategies;
• ScyllaDB support;
• Server events listening;
• Multiple CQL version support (3, 4), full spec implementation;
• Query tracing information.

Documentation and examples

• User guide.
• Examples.
• API docs (release).

Getting started

Add CDRS to your Cargo.toml file as a dependency:

toml cdrs = { version = "2" }

Then add it as an external crate to your main.rs:

```rust extern crate cdrs;

use cdrs::authenticators::NoneAuthenticator; use cdrs::cluster::session::{new as newsession}; use cdrs::cluster::{ClusterTcpConfig, NodeTcpConfigBuilder}; use cdrs::loadbalancing::RoundRobin; use cdrs::query::*;

fn main() { let node = NodeTcpConfigBuilder::new("127.0.0.1:9042", NoneAuthenticator {}).build(); let clusterconfig = ClusterTcpConfig(vec![node]); let nocompression = newsession(&clusterconfig, RoundRobin::new()).expect("session should be created");

let createks: &'static str = "CREATE KEYSPACE IF NOT EXISTS testks WITH REPLICATION = { \ 'class' : 'SimpleStrategy', 'replicationfactor' : 1 };"; nocompression.query(create_ks).expect("Keyspace create error"); } ```

This example configures a cluster consisting of a single node, and uses round robin load balancing and default r2d2 values for connection pool.
