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.ymd(1970, 12, 12).and_hms(0, 0, 0);

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

`DurationExceedsLimit`

Error when Duration.num_nanoseconds exceeds the limit.

let dt = Utc.ymd(2260, 12, 31).and_hms_nano(23, 59, 59, 1_75_500_000);

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

`TimestampExceedsLimit`

Error when DateTime.timestamp_nanos exceeds the limit.

let dt = Utc.ymd(2300, 12, 12).and_hms(0, 0, 0);

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