Expand description
Serialize a datetime into an integer number of microseconds since the epoch or none
Intended for use with serde
s serialize_with
attribute.
Example:
use chrono::naive::serde::ts_microseconds_option::serialize as to_micro_tsopt;
#[derive(Serialize)]
struct S {
#[serde(serialize_with = "to_micro_tsopt")]
time: Option<NaiveDateTime>
}
let my_s = S {
time: Some(NaiveDate::from_ymd_opt(2018, 5, 17).unwrap().and_hms_micro_opt(02, 04, 59, 918355).unwrap()),
};
let as_string = serde_json::to_string(&my_s)?;
assert_eq!(as_string, r#"{"time":1526522699918355}"#);
