Struct Lang

pub struct Lang {
    pub langs: Arc<Vec<Arc<LangItem>>>,
    pub list: Arc<BTreeMap<i64, BTreeMap<i64, BTreeMap<i64, Arc<BTreeMap<i64, String>>>>>>,
    pub default: usize,
    /* private fields */
}

Descrives all languages

Values

• langs: Vec<LangItem> - List of languages
• list: LangList - List of translations
• default: usize - Default language

Fields

langs: Arc<Vec<Arc<LangItem>>>

List of languages

list: Arc<BTreeMap<i64, BTreeMap<i64, BTreeMap<i64, Arc<BTreeMap<i64, String>>>>>>

List of translations

default: usize

Default language

Implementations

impl Lang

pub async fn new(root: Arc<String>, default_lang: &str, db: &mut DB) -> Lang

Reads ./app/ and recognizes translations

Description

In the root directory of the project (Init::root_path) the app directory is searched.

Translation files are logically located in this directory.
Each file must be named LangItem::lang and have the extension .lang

Example:

• English: ./app/module_name/class_name/en.lang
• Ukrainian: ./app/module_name/class_name/uk.lang

module_name - Name of the module
class_name - Class name

For all controllers in the same class - one translation file in one language is used.

Each translation file is divided into lines.
Each line consists of a key and a translation.

Example:

en.lang
about=About
articles=Articles
article=Article
contact=Contact
terms=Terms Conditions
policy=Privacy Policy

Use in the controller:

To get a translation, it is enough to set the this.lang("contact") function, which will return the corresponding translation.
If no translation is found, the key will be returned.
