Expand description

An error from rounding by Duration

See: DurationRound

Variants

DurationExceedsTimestamp

Error when the Duration exceeds the Duration from or until the Unix epoch.

let dt = Utc.with_ymd_and_hms(1970, 12, 12, 0, 0, 0).unwrap();

assert_eq!(
    dt.duration_round(Duration::days(365)),
    Err(RoundingError::DurationExceedsTimestamp),
);

DurationExceedsLimit

Error when Duration.num_nanoseconds exceeds the limit.

let dt = NaiveDate::from_ymd_opt(2260, 12, 31).unwrap().and_hms_nano_opt(23, 59, 59, 1_75_500_000).unwrap().and_local_timezone(Utc).unwrap();

assert_eq!(
    dt.duration_round(Duration::days(300 * 365)),
    Err(RoundingError::DurationExceedsLimit)
);

TimestampExceedsLimit

Error when DateTime.timestamp_nanos exceeds the limit.

let dt = Utc.with_ymd_and_hms(2300, 12, 12, 0, 0, 0).unwrap();

assert_eq!(dt.duration_round(Duration::days(1)), Err(RoundingError::TimestampExceedsLimit),);
