Function chrono::serde::ts_nanoseconds::deserialize

pub fn deserialize<'de, D>(d: D) -> Result<DateTime<Utc>, D::Error>where
    D: Deserializer<'de>,

Deserialize a DateTime from a nanosecond timestamp

Intended for use with serdes deserialize_with attribute.

Example:

use chrono::serde::ts_nanoseconds::deserialize as from_nano_ts;
#[derive(Debug, PartialEq, Deserialize)]
struct S {
    #[serde(deserialize_with = "from_nano_ts")]
    time: DateTime<Utc>
}

let my_s: S = serde_json::from_str(r#"{ "time": 1526522699918355733 }"#)?;
assert_eq!(my_s, S { time: Utc.timestamp_opt(1526522699, 918355733).unwrap() });
