Struct LangStr

pub struct LangStr<'a> { /* private fields */ }

Language string reference.

A language string is a string tagged with language and reading direction information.

A valid language string is associated to either a language tag or a direction, or both.

Implementations

impl<'a> LangStr<'a>

pub fn new( data: &'a str, language: Option<&'a LenientLangTag>, direction: Option<Direction>, ) -> Result<Self, InvalidLangString>

Create a new language string reference.

pub fn into_parts( self, ) -> (&'a str, Option<&'a LenientLangTag>, Option<Direction>)

pub fn as_str(&self) -> &'a str

Reference to the underlying str.

pub fn language(&self) -> Option<&'a LenientLangTag>

Gets the associated language tag, if any.

pub fn direction(&self) -> Option<Direction>

Gets the associated direction, if any.

Trait Implementations

impl<'a> Clone for LangStr<'a>

fn clone(&self) -> LangStr<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for LangStr<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for LangStr<'a>

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<'a> Ord for LangStr<'a>

fn cmp(&self, other: &LangStr<'a>) -> 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,

Restrict a value to a certain interval.

impl<'a> PartialEq for LangStr<'a>

fn eq(&self, other: &LangStr<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a> PartialOrd for LangStr<'a>

fn partial_cmp(&self, other: &LangStr<'a>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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