Struct PostgresConnectionManager

pub struct PostgresConnectionManager<T> { /* private fields */ }

An r2d2::ManageConnection for postgres::Clients.

Example

use std::thread;
use r2d2_postgres::{postgres::NoTls, PostgresConnectionManager};

fn main() {
    let manager = PostgresConnectionManager::new(
        "host=localhost user=postgres".parse().unwrap(),
        NoTls,
    );
    let pool = r2d2::Pool::new(manager).unwrap();

    for i in 0..10i32 {
        let pool = pool.clone();
        thread::spawn(move || {
            let mut client = pool.get().unwrap();
            client.execute("INSERT INTO foo (bar) VALUES ($1)", &[&i]).unwrap();
        });
    }
}
