Enum `RoundingError`

enum RoundingError

An error from rounding by TimeDelta

See: DurationRound

Variants

DurationExceedsTimestamp

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

Note: this error is not produced anymore.

DurationExceedsLimit

Error when TimeDelta.num_nanoseconds exceeds the limit.

# use chrono::{DurationRound, TimeDelta, RoundingError, NaiveDate};
let dt = NaiveDate::from_ymd_opt(2260, 12, 31)
    .unwrap()
    .and_hms_nano_opt(23, 59, 59, 1_75_500_000)
    .unwrap()
    .and_utc();

assert_eq!(
    dt.duration_round(TimeDelta::try_days(300 * 365).unwrap()),
    Err(RoundingError::DurationExceedsLimit)
);

TimestampExceedsLimit

Error when DateTime.timestamp_nanos exceeds the limit.

# use chrono::{DurationRound, TimeDelta, RoundingError, TimeZone, Utc};
let dt = Utc.with_ymd_and_hms(2300, 12, 12, 0, 0, 0).unwrap();

assert_eq!(
    dt.duration_round(TimeDelta::try_days(1).unwrap()),
    Err(RoundingError::TimestampExceedsLimit)
);
