Struct redis_r2d2::RedisConnectionManager

pub struct RedisConnectionManager { /* fields omitted */ }

An r2d2::ConnectionManager for redis::Clients.

Example

use std::ops::DerefMut;
use std::thread;

use redis_r2d2::{r2d2, redis, RedisConnectionManager};

fn main() {
    let manager = RedisConnectionManager::new("redis://localhost").unwrap();
    let pool = r2d2::Pool::builder()
        .build(manager)
        .unwrap();

    let mut handles = vec![];

    for _i in 0..10i32 {
        let pool = pool.clone();
        handles.push(thread::spawn(move || {
            let mut conn = pool.get().unwrap();
            let reply = redis::cmd("PING").query::<String>(conn.deref_mut()).unwrap();
            // Alternatively, without deref():
            let reply = redis::cmd("PING").query::<String>(&mut *conn).unwrap();
            assert_eq!("PONG", reply);
        }));
    }

    for h in handles {
        h.join().unwrap();
    }
}
