Redis keyspace notification in Rust

Enable keyspace notifications

By default, keyspace events notifications are disabled. We can enable them in redis.conf or redis-cli as below:

$ redis-cli config set notify-keyspace-events KEA
$ OK  

main.rs

extern crate redis;

fn listen_redis_notifications() -> redis::RedisResult<()> {

    let client = try!(redis::Client::open("redis://127.0.0.1/0"));
    let mut pubsub = try!(client.get_pubsub());
    try!(pubsub.psubscribe("__keyspace@0__:*"));
    try!(pubsub.psubscribe("__keyevent@0__:*"));
 
    loop {
        let msg = try!(pubsub.get_message());
        let payload : String = try!(msg.get_payload());
        println!("Channel '{}': {}", msg.get_channel_name(), payload);
    }
}


fn main() {
    match listen_redis_notifications() {
        Err(why) => panic!("{:?}", why),
        Ok(t) => println!("ok: {:?}", t),
    }
}
