Module ts_seconds_option

Ser/de to/from optional timestamps in seconds

Intended for use with serde’s with attribute.

Example:

use chrono::serde::ts_seconds_option;
#[derive(Deserialize, Serialize)]
struct S {
    #[serde(with = "ts_seconds_option")]
    time: Option<DateTime<Utc>>
}

let time = Some(Utc.with_ymd_and_hms(2015, 5, 15, 10, 0, 0).unwrap());
let my_s = S {
    time: time.clone(),
};

let as_string = serde_json::to_string(&my_s)?;
assert_eq!(as_string, r#"{"time":1431684000}"#);
let my_s: S = serde_json::from_str(&as_string)?;
assert_eq!(my_s.time, time);

Functions

• deserialize
  Deserialize a DateTime from a seconds timestamp or none
• serialize
