pub enum Error {
    DuplicateExtension,

    InvalidLanguage,
    SubtagTooLong,

}

Defines an Error type for langtags.

Errors occur mainly during parsing of language tags.

Variants

The same extension subtag is only allowed once in a tag before the private use part.

If an extension subtag is present, it must not be empty.

If the x subtag is present, it must not be empty.

The langtag contains a char that is not A-Z, a-z, 0-9 or the dash.

A subtag fails to parse, it does not match any other subtags.

The given language subtag is invalid.

A subtag may be eight characters in length at maximum.

At maximum three extlangs are allowed, but zero to one extlangs are preferred.
