fastdate

fastdate of Any RFC3339Micro

this date cartes is very fast(<= 50ns) including * fromstr("2022-12-13 11:12:14.123456") * now() * utc() * weekday() * tostring()/format!() * eq()/== * add()/sub() * setoffset() * parse("hh:mm:ss.000000,YYYY-MM-DD","11:12:14.123456,2022-12-13") * unixtimestamp() * unixtimestampmillis() * unixtimestampnano() * fromtimestamp() * fromtimestampmillis() * fromtimestampnano() * before(&date) -> bool * after(&date1) -> bool * from(v: SystemTime) * from(v: DateTime) * from(arg: Date) * from(arg: Time) * cmp(&self, other: &DateTime)/>/=/<= and more....

• it can fromstr for any RFC3339,iso8601 for example: log 1234_12_13_11_12_13.123456 1234-12-13T11:12:13 1234-12-13 11:12:13.123456 1234-12-13T11:12:13.123456 1234-12-13T11:12:13.123456Z 1234-12-13 11:12:13.123456+09:00

• how use? rust use fastdate::DateTime; fn main(){ //now with local time zone DateTime::now(); //utc time now DateTime::utc(); // add DateTime::now() + Duration::from_secs(1); // sub DateTime::now() - Duration::from_secs(1); //befor,after let date1 = DateTime::from_str("2022-12-12 00:00:00").unwrap(); let date2 = DateTime::from_str("2022-12-12 01:00:00").unwrap(); assert_eq!(date2.after(&date1), true); assert_eq!(date1.before(&date2), true); //from str let datetime=DateTime::from_str("1234-12-13 11:12:13.123456"); //from str time zone let datetime=DateTime::from_str("1234-12-13 11:12:13.123456+08:00"); let datetime=DateTime::from_str("1234-12-13 11:12:13.123456Z"); //parse by format str let date = DateTime::parse("hh:mm:ss.000000,YYYY-MM-DD","11:12:14.123456,2022-12-13").unwrap(); //to_string() let s = datetime.to_string();//1234-12-13 11:12:13.123456 //unix_timestamp let timestamp = DateTime::now().unix_timestamp(); //from unix_timestamp let datetime = DateTime::from_timestamp(timestamp); //unix_timestamp_millis let timestamp = DateTime::now().unix_timestamp_millis(); //from unix millis let datetime = DateTime::from_timestamp_millis(timestamp); //unix_timestamp_nano let timestamp = DateTime::now().unix_timestamp_nano(); //from unix_timestamp_nano let datetime = DateTime::from_timestamp_nano(timestamp); }
