Struct LangCode 

pub struct LangCode(/* private fields */);

A language’s tag, the name of its folder among the languages: BCP 47 (RFC 5646) in this subset, its subtags joined by -:

• the language: 2 to 8 letters (en, ja);
• a script, if any: 4 letters (zh-Hans);
• a region, if any: 2 letters or 3 digits (pt-BR, es-419);
• variants, each once: 5 to 8 letters or digits, or a digit and 3 letters or digits (de-CH-1996);
• a private-use part, if any: x and one or more subtags of 1 to 8 letters or digits (en-x-pseudo).

At most 35 characters in all. A tag has one spelling: the language, variants and private use in lower case, the script in title case and the region in upper case. A tag compares, orders and hashes as its text, so a map keyed by tags is looked up by &str too.

Implementations

impl LangCode

pub fn new(text: &str) -> Option<Self>

text as a tag, if it is one written as a tag is written (pt-BR, not pt_br); None otherwise. For text from outside, use parse.

pub fn parse(text: &str) -> Result<Self, TagError>

The tag text names, written as a tag is written: any case, _ for -, and a POSIX locale’s .charset and @modifier left out (pt_BR.UTF-8 is pt-BR). For the system’s languages and the command line. Fails with what is wrong.

pub fn english() -> Self

👎Deprecated:

a game’s source language is Lang::source_lang()

English, the source language when a game declares none.

pub fn as_str(&self) -> &str

The tag as text.

pub fn language(&self) -> &str

The language subtag: pt for pt-BR.

pub fn script(&self) -> Option<&str>

The script subtag, if the tag has one: Hans for zh-Hans-CN.

pub fn region(&self) -> Option<&str>

The region subtag, if the tag has one: BR for pt-BR.

pub fn parent(&self) -> Option<LangCode>

The tag without its last subtag (pt for pt-BR), a private-use part all at once (en for en-x-pseudo). None for a bare language.
