Rust postgres execute，如何将表名作为变量传递

use postgres::{Client, NoTls};

fn main() {
    let table_name = "my_table"; // 表名作为变量

    let mut client = Client::connect("host=localhost user=postgres", NoTls).unwrap();

    let query = format!("SELECT * FROM {}", table_name); // 使用表名变量生成查询语句

    let rows = client.query(query.as_str(), &[]).unwrap();

    for row in rows {
        let id: i32 = row.get(0);
        let name: &str = row.get(1);
        // 处理查询结果
        println!("id: {}, name: {}", id, name);
    }
}
