Enum icu::datetime::pattern::PatternLoadError

#[non_exhaustive]
pub enum PatternLoadError {
    ConflictingField(Field),
    UnsupportedLength(Field),
    TypeTooSpecific(Field),
    Data(DataError, Field),
}

Error returned from TypedDateTimeNames’s pattern load methods.

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.

ConflictingField(Field)

A field conflicts with a previous field.

Fields conflict if they require the same type of data, for example the EEE and EEEE fields (short vs long weekday) conflict, or the M and L (format vs standalone month) conflict.

UnsupportedLength(Field)

The field symbol is not supported in that length.

Some fields, such as O are not defined for all lengths (e.g. OO).

TypeTooSpecific(Field)

The specific type does not support this field.

This happens for example when trying to load a month field on a TypedDateTimeNames<Gregorian, ZoneFieldSet>.

Data(DataError, Field)

An error arising from the data provider for loading names.

Trait Implementations

impl Clone for PatternLoadError

fn clone(&self) -> PatternLoadError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternLoadError

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

Formats the value using the given formatter.

impl Display for PatternLoadError

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

Formats the value using the given formatter.

impl PartialEq for PatternLoadError

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