如何反序列化actix web表单数据并将其序列化为csv文件？

[dependencies]
actix-web = "x.x.x"
serde = { version = "x.x.x", features = ["derive"] }
serde-csv = "x.x.x"

use actix_web::{web, HttpResponse};
use serde::{Deserialize, Serialize};
use serde_csv;

#[derive(Debug, Deserialize)]
struct FormData {
    name: String,
    email: String,
}

async fn handle_form(form: web::Form<FormData>) -> HttpResponse {
    // 反序列化表单数据为FormData结构体
    let data: FormData = form.into_inner();

    // 将FormData结构体序列化为CSV文件
    let csv_data = serde_csv::to_string(&data).unwrap();

    // 将CSV数据保存到磁盘上
    // 这里假设你将CSV文件保存为名为data.csv的文件
    std::fs::write("data.csv", csv_data).unwrap();

    HttpResponse::Ok().body("Form data serialized and saved as CSV")
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    actix_web::HttpServer::new(|| {
        actix_web::App::new()
            .service(web::resource("/submit").route(web::post().to(handle_form)))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}
