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.

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<(), Error>

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<ParserError> 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 !=.
