CDRS is Apache Cassandra driver written in pure Rust.
- 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.
- User guide.
- Examples.
- API docs (release).
Add CDRS to your Cargo.toml file as a dependency:
cdrs = { version = "2" }Then add it as an external crate to your main.rs:
extern crate cdrs;
use cdrs::authenticators::NoneAuthenticator;
use cdrs::cluster::session::{new as new_session};
use cdrs::cluster::{ClusterTcpConfig, NodeTcpConfigBuilder};
use cdrs::load_balancing::RoundRobin;
use cdrs::query::*;
fn main() {
let node = NodeTcpConfigBuilder::new("127.0.0.1:9042", NoneAuthenticator {}).build();
let cluster_config = ClusterTcpConfig(vec![node]);
let no_compression =
new_session(&cluster_config, RoundRobin::new()).expect("session should be created");
let create_ks: &'static str = "CREATE KEYSPACE IF NOT EXISTS test_ks WITH REPLICATION = { \
'class' : 'SimpleStrategy', 'replication_factor' : 1 };";
no_compression.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.
