redis-cluster-async's Introduction

A Rust crate implementing a Redis cluster client.

Documentation is available at here.

This library builds upon the redis-rs crate to enable working with a Redis cluster (instead of single Redis nodes).

Example

extern crate futures;
extern crate tokio;
use futures::prelude::*;
use redis_cluster_async::{Client, redis::cmd};

fn main() {
    let nodes = vec!["redis://127.0.0.1:6379/", "redis://127.0.0.1:6378/", "redis://127.0.0.1:6377/"];

    let mut runtime = tokio::runtime::Runtime::new().unwrap();

    let client = Client::open(nodes).unwrap();
    let (_, res): (_, String) = runtime.block_on(client.get_connection()
        .and_then(|connection| {
            cmd("SET").arg("test").arg("test_data").clone()
                .query_async(connection)
                .and_then(|(connection, ())| 
                    cmd("GET").arg("test")
                        .query_async(connection)
                )
        })
        )
        .unwrap();

    assert_eq!(res, "test_data");
}

Pipelining

extern crate futures;
extern crate tokio;

use futures::prelude::*;
use redis_cluster_async::{Client, redis::{PipelineCommands, pipe}};

fn main() {
    let nodes = vec!["redis://127.0.0.1:6379/", "redis://127.0.0.1:6378/", "redis://127.0.0.1:6377/"];

    let mut runtime = tokio::runtime::Runtime::new().unwrap();

    let client = Client::open(nodes).unwrap();
    let _: (_, ()) = runtime.block_on(
        client.get_connection().and_then(|connection| {
            let key = "test";

            pipe()
                .rpush(key, "123").ignore()
                .ltrim(key, -10, -1).ignore()
                .expire(key, 60).ignore()
                .query_async(connection)
        }))
        .unwrap();
