Enum icu::locale::ParseError

#[non_exhaustive]
pub enum ParseError {
    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::locale::subtags::Language;
use icu::locale::ParseError;

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

InvalidSubtag

Invalid script, region or variant subtag.

Examples

use icu::locale::subtags::Region;
use icu::locale::ParseError;

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

InvalidExtension

Invalid extension subtag.

Examples

use icu::locale::extensions::unicode::Key;
use icu::locale::ParseError;

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

DuplicatedExtension

Duplicated extension.

Examples

use icu::locale::Locale;
use icu::locale::ParseError;

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

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for ParseError

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