Grandfathered tags.

Prior to RFC 4646, whole language tags were registered according to the rules in RFC 1766 and/or RFC 3066. All of these registered tags remain valid as language tags. Many of these registered tags were made redundant by the advent of either RFC 4646 or RFC 5646. The remainder of the previously registered tags are “grandfathered”, and are all veriants of this enum type.

Implementations

impl GrandfatheredLangTag

pub fn new<T: AsRef<[u8]>>(t: T) -> Result<GrandfatheredLangTag, T>

Try to parse a grandfathered tag.

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

Get the language of the grandfathered tag if it is regular.

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

Returns the bytes representation of the tag.

pub fn as_str(&self) -> &str

Returns the string representation of the tag.

Trait Implementations

impl Clone for GrandfatheredLangTag

fn clone(&self) -> GrandfatheredLangTag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for GrandfatheredLangTag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for GrandfatheredLangTag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GrandfatheredLangTag

fn cmp(&self, other: &GrandfatheredLangTag) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for GrandfatheredLangTag

fn eq(&self, other: &GrandfatheredLangTag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GrandfatheredLangTag

fn partial_cmp(&self, other: &GrandfatheredLangTag) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<&'a [u8]> for GrandfatheredLangTag

type Error = InvalidGrandfatheredTag<&'a [u8]>

The type returned in the event of a conversion error.

fn try_from(bytes: &'a [u8]) -> Result<GrandfatheredLangTag, Self::Error>

Performs the conversion.
