Expand description

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

Re-exported as Error.

Variants (Non-exhaustive)

This enum is marked as 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
