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.

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_unchecked, 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_unchecked, 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_unchecked, 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_unchecked, and the pattern contains unsupported fields.

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

Trait Implementations

impl Clone for DateTimeWriteError

fn clone(&self) -> DateTimeWriteError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateTimeWriteError

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

Formats the value using the given formatter.

impl Display for DateTimeWriteError

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

Formats the value using the given formatter.

impl PartialEq for DateTimeWriteError

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

Tests for self and other values to be equal, and is used by ==.

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

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