Module chrono::naive::serde::ts_nanoseconds
source · Expand description
Used to serialize/deserialize from nanosecond-precision timestamps
§Example:
use chrono::naive::serde::ts_nanoseconds;
#[derive(Deserialize, Serialize)]
struct S {
#[serde(with = "ts_nanoseconds")]
time: NaiveDateTime,
}
let time = NaiveDate::from_ymd_opt(2018, 5, 17)
.unwrap()
.and_hms_nano_opt(02, 04, 59, 918355733)
.unwrap();
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);
