Struct langtag::PrimaryLanguage

pub struct PrimaryLanguage<T: ?Sized = [u8]> { /* fields omitted */ }

Primary language subtag.

The primary language subtag is the first subtag in a language tag.

Implementations

impl<T: AsRef<[u8]>> PrimaryLanguage<T>

pub fn new(t: T) -> Result<PrimaryLanguage<T>, Error>
