Variants (Non-exhaustive)
This enum is marked as 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 core::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 core::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 core::str::FromStr;
use icu::locid::extensions::unicode::Key;
use icu::locid::ParserError;
assert_eq!(Key::from_str("#@2X"), Err(ParserError::InvalidExtension));
