Enum chrono::RoundingError

pub enum RoundingError {
    DurationExceedsTimestamp,
    DurationExceedsLimit,
    TimestampExceedsLimit,
}

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),);

Trait Implementations

impl Clone for RoundingError

fn clone(&self) -> RoundingError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoundingError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RoundingError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for RoundingError

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<RoundingError> for RoundingError

fn eq(&self, other: &RoundingError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
