下面的示例，演示如何使用[serde]箱子。

# #[macro_use]
# extern crate error_chain;
extern crate csv;
#[macro_use]
extern crate serde_derive;

use std::io;
#
# error_chain! {
#    foreign_links {
#        IOError(std::io::Error);
#        CSVError(csv::Error);
#    }
# }

#[derive(Serialize)]
struct Record<'a> {
    name: &'a str,
    place: &'a str,
    id: u64,
}

fn run() -> Result<()> {
    let mut wtr = csv::Writer::from_writer(io::stdout());

    let rec1 = Record { name: "Mark", place: "Melbourne", id: 56};
    let rec2 = Record { name: "Ashley", place: "Sydney", id: 64};
    let rec3 = Record { name: "Akshat", place: "Delhi", id: 98};

    wtr.serialize(rec1)?;
    wtr.serialize(rec2)?;
    wtr.serialize(rec3)?;

    wtr.flush()?;

    Ok(())
}
