Enum language_tags::Error

pub enum Error {
    DuplicateExtension,
    EmptyExtension,
    EmptyPrivateUse,
    ForbiddenChar,
    InvalidSubtag,
    InvalidLanguage,
    SubtagTooLong,
    TooManyExtlangs,
}

Defines an Error type for langtags.

Errors occur mainly during parsing of language tags.

Variants

DuplicateExtension	The same extension subtag is only allowed once in a tag before the private use part.
EmptyExtension	If an extension subtag is present, it must not be empty.
EmptyPrivateUse	If the x subtag is present, it must not be empty.
ForbiddenChar	The langtag contains a char that is not A-Z, a-z, 0-9 or the dash.
InvalidSubtag	A subtag fails to parse, it does not match any other subtags.
InvalidLanguage	The given language subtag is invalid.
SubtagTooLong	A subtag may be eight characters in length at maximum.
TooManyExtlangs	At maximum three extlangs are allowed, but zero to one extlangs are preferred.
