Error for TryWriteable implementations

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.
§

InvalidMonthCode(MonthCode)

The MonthCode of the input is not valid for this calendar.

This is guaranteed not to happen for icu::calendar inputs, but may happen for custom inputs.

The output will contain the raw MonthCode as a fallback value.

§

InvalidEra(FormattingEra)

The FormattingEra of the input is not valid for this calendar.

This is guaranteed not to happen for icu::calendar inputs, but may happen for custom inputs.

The output will contain FormattingEra::fallback_name as the fallback.

§

InvalidCyclicYear

The [YearInfo::cyclic] of the input is not valid for this calendar.

This is guaranteed not to happen for icu::calendar inputs, but may happen for custom inputs.

The output will contain [YearInfo::extended_year] as a fallback value.

Fields

§value: usize

Value

§max: usize

Max

§

FixedDecimalFormatterNotLoaded

The [FixedDecimalFormatter] has not been loaded.

This only happens if the formatter has been created using [TypedDateTimeNames::with_pattern], the pattern requires decimal formatting, and the decimal formatter was not loaded.

The output will contain fallback values using Latin numerals.

§

NamesNotLoaded(Field)

The localized names for a field have not been loaded.

This only happens if the formatter has been created using [TypedDateTimeNames::with_pattern], and the pattern requires names that were not loaded.

The output will contain fallback values using field identifiers (such as tue for IsoWeekday::Tuesday, M02 for month 2, etc.).

§

MissingInputField(&'static str)

An input field (such as “hour” or “month”) is missing.

This only happens if the formatter has been created using [TypedDateTimeNames::with_pattern], and the pattern requires fields that are not returned by the input type.

The output will contain the string {X} instead, where X is the symbol for which the input is missing.

§

UnsupportedField(Field)

Unsupported field

This only happens if the formatter has been created using [TypedDateTimeNames::with_pattern], and the pattern contains unsupported fields.

The output will contain the string {unsupported:X}, where X is the symbol of the unsupported field.
