S: Serializer,
Expand description
Serialize a UTC datetime into an integer number of milliseconds since the epoch
Intended for use with serde
s serialize_with
attribute.
§Example:
use chrono::serde::ts_milliseconds::serialize as to_milli_ts;
#[derive(Serialize)]
struct S {
#[serde(serialize_with = "to_milli_ts")]
time: DateTime<Utc>,
}
let my_s = S {
time: NaiveDate::from_ymd_opt(2018, 5, 17)
.unwrap()
.and_hms_milli_opt(02, 04, 59, 918)
.unwrap()
.and_utc(),
};
let as_string = serde_json::to_string(&my_s)?;
assert_eq!(as_string, r#"{"time":1526522699918}"#);
