Function chrono::naive::serde::ts_milliseconds_option::deserialize

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

Deserialize a NaiveDateTime from a nanosecond timestamp or none

Intended for use with serdes deserialize_with attribute.

Example:

use chrono::naive::serde::ts_milliseconds_option::deserialize as from_milli_tsopt;
#[derive(Deserialize)]
struct S {
    #[serde(deserialize_with = "from_milli_tsopt")]
    time: Option<NaiveDateTime>
}

let my_s: S = serde_json::from_str(r#"{ "time": 1526522699918355 }"#)?;
