Enum icu_locid::ParserError

pub enum ParserError {
    InvalidLanguage,
    InvalidSubtag,
    InvalidExtension,
}

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

Variants

InvalidLanguage

Invalid language subtag.

Examples

use std::str::FromStr;

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

assert_eq!(Language::from_str("x2"), Err(ParserError::InvalidLanguage));

InvalidSubtag

Invalid script, region or variant subtag.

Examples

use std::str::FromStr;

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

assert_eq!(Region::from_str("#@2X"), Err(ParserError::InvalidSubtag));

InvalidExtension

Invalid extension subtag.

Examples

use std::str::FromStr;

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

assert_eq!(Key::from_str("#@2X"), Err(ParserError::InvalidExtension));

Trait Implementations

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParserError

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

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub 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 ==.

#[must_use]

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

This method tests for !=.
