r2d2-diesel

Provides r2d2 support to allow connection pooling with Diesel.

Example

This example creates a connection pool with default settings for a PostgreSQL database running on localhost, then creates a bunch of threads and acquires a connection from the pool for each thread. An executable version of this example is in examples/postgres.rs which you can run with cargo run --example postgres.

```rust extern crate diesel; extern crate r2d2; extern crate r2d2_diesel;

use std::thread;

use diesel::pg::PgConnection; use r2d2_diesel::ConnectionManager;

fn main() { let config = r2d2::Config::default(); let manager = ConnectionManager::::new("postgres://localhost/"); let pool = r2d2::Pool::new(config, manager).expect("Failed to create pool.");

for _ in 0..10i32 {
    let pool = pool.clone();
    thread::spawn(move || {
        let connection = pool.get();

        assert!(connection.is_ok());
    });
}

} ```
