impl<'a, T> Ord for LanguageTag<'a, T>

where T: AsRef<[u8]> + ?Sized,

fn cmp(&self, other: &LanguageTag<'a, T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
