A list of error outcomes for various operations in the icu_datetime crate.

Re-exported as Error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Pattern(PatternError)

An error originating from parsing a pattern.

Format(Error)

An error originating from the Write trait.

Data(DataError)

An error originating inside of the data provider.

MissingInputField(Option<&'static str>)

An error originating from a missing field in datetime input. TODO: How can we return which field was missing?

Skeleton(SkeletonError)

An error originating from skeleton matching.

UnsupportedField(FieldSymbol)

An error originating from an unsupported field in a datetime format.

UnsupportedOptions

An error due to there being no patterns for the given options.

PluralRules(PluralsError)

An error originating from PluralRules.

DateTimeInput(CalendarError)

An error originating from DateTimeInput.

MissingWeekdaySymbol(usize)

An error originating from a missing weekday symbol in the data.

MissingMonthSymbol(MonthCode)

An error originating from a missing month symbol in the data.

FixedDecimal

An error while attempting to format the input as a FixedDecimal

FixedDecimalFormatter(DecimalError)

An error originating from FixedDecimalFormatter

MismatchedAnyCalendar(AnyCalendarKind, Option<AnyCalendarKind>)

An error from mixing calendar types in DateTimeFormatter

MissingDateSymbols

Missing date symbols

MissingTimeSymbols

Missing time symbols

MissingOrdinalRules

ordinal_rules must be set for PatternPlurals::MultipleVariants

Trait Implementations

impl Clone for DateTimeError

fn clone(&self) -> DateTimeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateTimeError

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

Formats the value using the given formatter.

impl Display for DateTimeError

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

Formats the value using the given formatter.

impl Error for DateTimeError

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

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

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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 From<CalendarError> for DateTimeError

fn from(e: CalendarError) -> Self

Converts to this type from the input type.

impl From<DataError> for DateTimeError

fn from(e: DataError) -> Self

Converts to this type from the input type.

impl From<Error> for DateTimeError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<PluralsError> for DateTimeError

fn from(e: PluralsError) -> Self

Converts to this type from the input type.

impl PartialEq<DateTimeError> for DateTimeError

fn eq(&self, other: &DateTimeError) -> 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.

impl Copy for DateTimeError

impl StructuralPartialEq for DateTimeError
