【Rust项目推荐】异步连接池mobc更新, 支持tokio0.2和async-std，欢迎使用

[dependencies]
mobc = "0.3"

use tokio;

#[tokio::main]
async fn main() {
    let manager = mobc_foodb::FooConnectionManager::new("localhost:1234");
    let pool = mobc::Pool::builder()
        .max_size(15)
        .build(manager)
        .await
        .unwrap();

    for _ in 0..20 {
        let pool = pool.clone();
        tokio::spawn(async {
            let conn = pool.get().await.unwrap();
            // use the connection
            // it will be returned to the pool when it falls out of scope.
        });
    }
}
