§DateTime NewType set for default time

Latest Version GitHub license

When you want to use #[derive(Default)] to a struct, you may want the current time to be the default for DateTime. For this purpose, we have provided NewType that overrides the default value.

§Features

§DateTimeDefaultNow

DateTime with current time as default.

ⓘ
use chrono::{Local, TimeZone};
use datetime_default::DateTimeDefaultNow;

assert_eq!(
    DateTimeDefaultNow::<Local>::default(),
    Local.datetime_from_str("2022/10/10 23:40:11.695164300", "%Y/%m/%d %H:%M:%S%.9f").unwrap()
);

§DateTimeDefaultUnix

DateTime with UNIX epoch as default.

use chrono::{Utc, TimeZone};
use datetime_default::DateTimeDefaultUnix;

assert_eq!(
    DateTimeDefaultUnix::<Utc>::default(),
    Utc.datetime_from_str("1970/1/1 00:00:00", "%Y/%m/%d %H:%M:%S").unwrap()
);

§Default Datetime with TimeZone

use chrono::{DateTime, FixedOffset, TimeZone};
use datetime_default::DateTimeDefaultUnix;

assert_eq!(
    DateTimeDefaultUnix::<FixedOffset, 9>::default(),
    DateTime::parse_from_rfc3339("1970-01-01T09:00:00+09:00").unwrap()
);
