Module chrono::datetime::serde::ts_nanoseconds

Ser/de to/from timestamps in nanoseconds

Intended for use with serde’s with attribute.

Example:

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

let time = NaiveDate::from_ymd_opt(2018, 5, 17)
    .unwrap()
    .and_hms_nano_opt(02, 04, 59, 918355733)
    .unwrap()
    .and_utc();
let my_s = S { time: time.clone() };

let as_string = serde_json::to_string(&my_s)?;
assert_eq!(as_string, r#"{"time":1526522699918355733}"#);
let my_s: S = serde_json::from_str(&as_string)?;
assert_eq!(my_s.time, time);

Functions

• deserialize
  Deserialize a DateTime from a nanosecond timestamp
• serialize
  Serialize a UTC datetime into an integer number of nanoseconds since the epoch
