Module ts_microseconds_option

Available on crate feature chrono only.

Ser/de to/from optional timestamps in microseconds

Intended for use with serde’s with attribute.

Example:

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

let time = Some(
    NaiveDate::from_ymd_opt(2018, 5, 17)
        .unwrap()
        .and_hms_micro_opt(02, 04, 59, 918355)
        .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":1526522699918355}"#);
let my_s: S = serde_json::from_str(&as_string)?;
assert_eq!(my_s.time, time);

Functions

• deserialize
  Deserialize a DateTime from a microsecond timestamp or none
• serialize
  Serialize a UTC datetime into an integer number of microseconds since the epoch or none
