Enum icu_locid::ParserError

#[non_exhaustive]
pub enum ParserError {
    InvalidLanguage,
    InvalidSubtag,
    InvalidExtension,
    DuplicatedExtension,
}

List of parser errors that can be generated while parsing LanguageIdentifier, Locale, subtags or extensions.

Re-exported as Error.

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.

InvalidLanguage

Invalid language subtag.

Examples

use icu::locid::subtags::Language;
use icu::locid::ParserError;

assert_eq!("x2".parse::<Language>(), Err(ParserError::InvalidLanguage));

InvalidSubtag

Invalid script, region or variant subtag.

Examples

use icu::locid::subtags::Region;
use icu::locid::ParserError;

assert_eq!("#@2X".parse::<Region>(), Err(ParserError::InvalidSubtag));

InvalidExtension

Invalid extension subtag.

Examples

use icu::locid::extensions::unicode::Key;
use icu::locid::ParserError;

assert_eq!("#@2X".parse::<Key>(), Err(ParserError::InvalidExtension));

DuplicatedExtension

Duplicated extension.

Examples

use icu::locid::Locale;
use icu::locid::ParserError;

assert_eq!(
    "und-u-hc-h12-u-ca-calendar".parse::<Locale>(),
    Err(ParserError::DuplicatedExtension)
);

Trait Implementations

impl Clone for ParserError

fn clone(&self) -> ParserError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl PartialEq for ParserError

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

This method tests for self and other values to be equal, and is used by ==.

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

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