Implementations

impl AcceptLanguage

pub fn get_first_region(&self) -> Option<Region>

Get the first region. For example, a region can be "US", "TW" or "GB".

pub fn get_first_language(&self) -> Option<Language>

Get the first language. For example, a language can be "en", "zh" or "jp".

pub fn get_first_language_region(&self) -> Option<(Language, Option<Region>)>

Get the first language-region pair. The region might not exist. For example, a language-region pair can be ("en", Some("US")), ("en", Some("GB")), ("zh", Some("TW")) or ("zh", None).

pub fn get_appropriate_language_region(
    &self,
    locales: &[LanguageIdentifier]
) -> Option<(Language, Option<Region>)>

Get the appropriate language-region pair. If the region can not be matched, and there is no matched language-region pairs, returns the first matched language.
