Example

use deadpool_redis::{redis::{cmd, FromRedisValue}, Config, Runtime};

#[tokio::main]
async fn main() {
    let mut cfg = Config::from_url("redis://127.0.0.1/");
    let pool = cfg.create_pool(Some(Runtime::Tokio1)).unwrap();
    {
        let mut conn = pool.get().await.unwrap();
        cmd("SET")
            .arg(&["deadpool/test_key", "42"])
            .query_async::<_, ()>(&mut conn)
            .await.unwrap();
    }
    {
        let mut conn = pool.get().await.unwrap();
        let value: String = cmd("GET")
            .arg(&["deadpool/test_key"])
            .query_async(&mut conn)
            .await.unwrap();
        assert_eq!(value, "42".to_string());
    }
}

Example with config and dotenv crate

use deadpool_redis::{redis::{cmd, FromRedisValue}, Runtime};
use dotenv::dotenv;
# use serde_1 as serde;

#[derive(Debug, serde::Deserialize)]
# #[serde(crate = "serde_1")]
struct Config {
    #[serde(default)]
    redis: deadpool_redis::Config
}

impl Config {
      pub fn from_env() -> Result<Self, config::ConfigError> {
         config::Config::builder()
            .add_source(config::Environment::default().separator("__"))
            .build()?
            .try_deserialize()
    }
}

#[tokio::main]
async fn main() {
    dotenv().ok();
    let cfg = Config::from_env().unwrap();
    let pool = cfg.redis.create_pool(Some(Runtime::Tokio1)).unwrap();
    {
        let mut conn = pool.get().await.unwrap();
        cmd("SET")
            .arg(&["deadpool/test_key", "42"])
            .query_async::<_, ()>(&mut conn)
            .await.unwrap();
    }
    {
        let mut conn = pool.get().await.unwrap();
        let value: String = cmd("GET")
            .arg(&["deadpool/test_key"])
            .query_async(&mut conn)
            .await.unwrap();
        assert_eq!(value, "42".to_string());
    }
}

FAQ

  • How can I enable features of the redis crate?

    Make sure that you depend on the same version of redis as deadpool-redis does and enable the needed features in your own Crate.toml file:

    [dependencies]
deadpool-redis = { version = "0.9", features = ["serde"] }
redis = { version = "0.21", default-features = false, features = ["tls"] }
