pub enum LanguageTag<'a, T: ?Sized = [u8]> {
    Normal(LangTag<&'a T>),
    PrivateUse(&'a PrivateUseTag<T>),
    Grandfathered(GrandfatheredTag),
}

Language tag with borrowed data.

Variants

Normal(LangTag<&'a T>)

Implementations

impl<'a, T: AsRef<[u8]> + ?Sized> LanguageTag<'a, T>

pub fn as_bytes(&self) -> &[u8]

Returns the bytes representation of the language tag.

pub fn as_str(&self) -> &str

Returns the string representation of the language tag.

pub fn is_normal(&self) -> bool

Checks if this is a normal language tag.

pub fn is_private_use(&self) -> bool

Checks if this is a private use tag.

pub fn is_grandfathered(&self) -> bool

Checks if this is a grandfathered tag.

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

Get the language subtags, if any.

pub fn parse<T: AsRef<[u8]> + ?Sized>(
    t: &'a T
) -> Result<LanguageTag<'a>, Error>
