Examples

use nt_time::{
    serde::{Deserialize, Serialize},
    serde_with::iso_8601,
    FileTime,
};

#[derive(Debug, Deserialize, PartialEq, Serialize)]
struct DateTime(#[serde(with = "iso_8601::option")] Option<FileTime>);

let json = serde_json::to_string(&DateTime(Some(FileTime::UNIX_EPOCH))).unwrap();
assert_eq!(json, r#""+001970-01-01T00:00:00.000000000Z""#);

assert_eq!(
    serde_json::from_str::<DateTime>(&json).unwrap(),
    DateTime(Some(FileTime::UNIX_EPOCH))
);

let json = serde_json::to_string(&DateTime(None)).unwrap();
assert_eq!(json, "null");

assert_eq!(
    serde_json::from_str::<DateTime>(&json).unwrap(),
    DateTime(None)
);
