如何在Rust中从MySQL中获取二进制列？

[dependencies]
mysql_async = "0.23.0"
tokio = { version = "1", features = ["full"] }

use mysql_async::{prelude::*, Conn, Opts, OptsBuilder, Row};
use tokio::runtime::Runtime;

fn main() {
    // 创建一个运行时环境
    let mut rt = Runtime::new().unwrap();

    // 创建MySQL连接选项
    let opts = Opts::new()
        .ip_or_hostname("localhost")
        .user("username")
        .pass("password")
        .db_name("database");

    // 创建连接池
    let pool = rt.block_on(async {
        let builder = OptsBuilder::from_opts(opts);
        mysql_async::Pool::new(builder)
    });

    // 从连接池获取连接
    let conn = rt.block_on(async { pool.get_conn().await.unwrap() });

    // 执行查询语句
    let result = rt.block_on(async {
        conn.query("SELECT binary_column FROM table_name")
            .await
            .unwrap()
    });

    // 处理查询结果
    for row in result {
        let binary_column: Vec<u8> = row.get(0).unwrap();
        // 在这里进行二进制列的处理
        println!("{:?}", binary_column);
    }
}
