Redis library for rust

redis-rs // A High Level Redis Library for Rust

  redis-rs provides both low level access to redis functionality
  as well as high level wrappers around them.  It supports simple
  multi-connection handling to allow different tasks to all
  connect to redis.  (Currently without pooling)

To build:

  $ make

To test:

  $ make test

To compile and run the example:

  $ make example
  $ ./build/redis-example


Low-level example:

    extern crate redis;
    use std::str::from_utf8;

    fn main() {
      let client = redis::Client::open("redis://127.0.0.1/").unwrap();
      let mut con = client.get_connection().unwrap();
      con.send_command("GET", [redis::StrArg("my_key")]);
      match con.read_response() {
	redis::Data(value) => {
          println!("Got value: {}", from_utf8(value).unwrap());
        },
        redis::Error(redis::ResponseError, msg) => {
            fail!(format!("Redis command failed: {}", msg));
        },
	_ => {
          println!("Did not get value :-(");
	}
      }
    }

High-level example:

    extern crate redis;

    fn main() {
      let client = redis::Client::open("redis://127.0.0.1/").unwrap();
      let mut con = client.get_connection().unwrap();
      println!("Got value: {}", con.get("my_key").unwrap_or("<no value>"));
    }

Scanning over all keys iteratively:

    extern crate redis;

    fn main() {
      let client = redis::Client::open("redis://127.0.0.1/").unwrap();
      let mut con = client.get_connection().unwrap();
      println!("iterate over all keys starting with 'key:':");
      for item in con.scan("key:*") {
        println!(" > {}", item);
        // note that keys might appear more than once due to how redis
        // stateless cursors are implemented.
      }
    }
