Deadpool is a dead simple async pool for connections and objects of any type.

This crate implements a deadpool manager for redis.

Example

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

#[tokio::main]
async fn main() {
    let mut cfg = Config::default();
    cfg.url = Some("redis://127.0.0.1/".to_string());
    let pool = cfg.create_pool(Runtime::NoRuntime).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::Runtime;
use deadpool_redis::redis::{cmd, FromRedisValue};
use dotenv::dotenv;
use serde::Deserialize;

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

impl Config {
    pub fn from_env() -> Result<Self, ::config_crate::ConfigError> {
        let mut cfg = ::config_crate::Config::new();
        cfg.merge(::config_crate::Environment::new().separator("__"))?;
        cfg.try_into()
    }
}

#[tokio::main]
async fn main() {
    dotenv().ok();
    let cfg = Config::from_env().unwrap();
    let pool = cfg.redis.create_pool(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 = "0.8", features = ["config"] }
  redis = { version = "0.20", default-features = false, features = ["tls"] }
