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<(), Error>

Formats the value using the given formatter.

impl Display for DateTimeWriteError

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

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.
