r2d2连接池，基于Steven Fackler的r2d2-postgres。

文档

lib.rs:

为r2d2连接池提供Sqlite支持。

库crate: r2d2-sqlite

集成: r2d2 和 rusqlite

示例

extern crate r2d2;
extern crate r2d2_sqlite;
extern crate rusqlite;

use std::thread;
use r2d2_sqlite::SqliteConnectionManager;
use rusqlite::params;

fn main() {
    let manager = SqliteConnectionManager::file("file.db");
    let pool = r2d2::Pool::new(manager).unwrap();
    pool.get()
        .unwrap()
        .execute("CREATE TABLE IF NOT EXISTS foo (bar INTEGER)", params![])
        .unwrap();

    (0..10)
        .map(|i| {
            let pool = pool.clone();
            thread::spawn(move || {
                let conn = pool.get().unwrap();
                conn.execute("INSERT INTO foo (bar) VALUES (?)", &[&i])
                    .unwrap();
            })
        })
        .collect::<Vec<_>>()
        .into_iter()
        .map(thread::JoinHandle::join)
        .collect::<Result<_, _>>()
        .unwrap()
}
