Function chrono::serde::ts_nanoseconds::serialize [−][src]
pub fn serialize<S>(
dt: &DateTime<Utc>,
serializer: S
) -> Result<S::Ok, S::Error> where
S: Serializer,
Serialize a UTC datetime into an integer number of nanoseconds since the epoch
Intended for use with serde
s serialize_with
attribute.
Example:
use chrono::serde::ts_nanoseconds::serialize as to_nano_ts; #[derive(Serialize)] struct S { #[serde(serialize_with = "to_nano_ts")] time: DateTime<Utc> } let my_s = S { time: Utc.ymd(2018, 5, 17).and_hms_nano(02, 04, 59, 918355733), }; let as_string = serde_json::to_string(&my_s)?; assert_eq!(as_string, r#"{"time":1526522699918355733}"#);
