pub enum Language {
    // some variants omitted
}

Implementations

impl Language

pub fn to_639_3(&self) -> &'static str

Create string representation of this Language as a ISO 639-3 code.

This method will return the ISO 639-3 code, which consists of three letters.

Example

use isolang::Language;

assert_eq!(Language::Deu.to_639_3(), "deu");

pub fn to_639_1(&self) -> Option<&'static str>

Create two-letter ISO 639-1 representation of the language.

This will return a two-letter ISO 639-1 code, if it exists and None otherwise. ISO 639-1 codes are only used for the most common languages.

Example

use isolang::Language;

assert!(Language::Gha.to_639_1().is_none());

pub fn to_name(&self) -> &'static str

Get the English name of this language.

This returns the English name of the language, as defined in the ISO 639 standard. It does not include additional comments, e.g. classification of a macrolanguage, etc.

Examples

use isolang::Language;

assert_eq!(Language::Spa.to_name(), "Spanish");
// macro language
assert_eq!(Language::Swa.to_name(), "Swahili");
// individual language
assert_eq!(Language::Swh.to_name(), "Swahili");

pub fn from_639_1(code: &str) -> Option<Language>

Create a Language instance rom a ISO 639-1 code.

This will return a Language instance if the given string is a valid two-letter language code. For invalid inputs, None is returned.

Example

use isolang::Language;

assert!(Language::from_639_1("de").is_some());
assert!(Language::from_639_1("…").is_none());

pub fn from_639_3(code: &str) -> Option<Language>

Create a Language instance rom a ISO 639-3 code.

This will return a Language instance if the given string is a valid three-letter language code. For invalid inputs, None is returned.

Example

use isolang::Language;

assert!(Language::from_639_3("dan").is_some());
assert!(Language::from_639_1("…").is_none());

pub fn from_locale(locale: &str) -> Option<Language>

Parse language from given locale

This parses a language from a given locale string, as used by UNIX-alike and other systems.

Example

use isolang::Language;

fn main() {
    assert!(Language::from_locale("de_DE.UTF-8") == Some(Language::Deu));
}

Trait Implementations

impl Clone for Language

fn clone(&self) -> Language

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Language

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

Formats the value using the given formatter.

impl Default for Language

fn default() -> Self

Returns the “default value” for a type.

impl Display for Language

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

Formats the value using the given formatter.

impl Hash for Language

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 PartialEq<Language> for Language

fn eq(&self, other: &Language) -> 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.
