Enum 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 duplicate 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

Formats the value using the given formatter.

impl Display for ParseError

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

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.

impl Copy for ParseError

impl StructuralPartialEq for ParseError

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
