Deadpool for PostgreSQL

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

This crate implements a deadpool manager for tokio-postgres and also provides a statement cache by wrapping tokio_postgres::Client and tokio_postgres::Transaction.

Features

Example

use deadpool_postgres::{Config, Manager, Pool};
use tokio_postgres::{NoTls};

#[tokio::main]
async fn main() {
    let mut cfg = Config::from_env("PG").unwrap();
    let pool = cfg.create_pool(NoTls).unwrap();
    for i in 1..10 {
        let mut client = pool.get().await.unwrap();
        let stmt = client.prepare("SELECT 1 + $1").await.unwrap();
        let rows = client.query(&stmt, &[&i]).await.unwrap();
        let value: i32 = rows[0].get(0);
        assert_eq!(value, i + 1);
    }
}
