#[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"] }
