Struct language_tag::tags::langtag::LangTag

pub struct LangTag { /* fields omitted */ }

This stores a LangTag that define a language (with script, country, ...) according to BCP47 standard. You have probably already seen some. Examples: "en-US" (english as used in US), "fr-FR" (french as used in France), "zh-cmn-Hans-CN" (Chinese, Mandarin, Simplified script, as used in China) Two possibilities to create a LangTag: parse a string or use the builder.

Methods

impl LangTag

fn get_language(&self) -> &TagLanguage

Get the TagLanguage containing the main language information and its extensions

Examples

use language_tag::tags::*;
use std::str::FromStr;

let langtag = LangTag::from_str("zh-cmn").unwrap();
let language = langtag.get_language();

assert_eq!(language.get_mainlang(), "zh");
assert_eq!(language.get_lang_extensions()[0], "cmn");

fn get_script(&self) -> Option<&TagScript>

Get the TagScript containing the script information

Examples

use language_tag::tags::*;
use std::str::FromStr;

let langtag = LangTag::from_str("en-Latn-US").unwrap();
if let Some(ref script) = langtag.get_script() {
    assert_eq!(script.str(), "Latn");
}

fn get_region(&self) -> Option<&TagRegion>

Get the TagRegion containing the region information

Examples

use language_tag::tags::*;
use std::str::FromStr;

let langtag = LangTag::from_str("en-Latn-US").unwrap();
if let Some(ref region) = langtag.get_region() {
    assert_eq!(region.str(), "US");
}

fn get_variants(&self) -> &Vec<TagVariant>

fn get_extensions(&self) -> &Vec<TagExtension>

fn get_privateuse(&self) -> &Option<TagExtension>
