Implementations§

Source §

impl Config

Source

pub fn new(directory: &str, languages: Vec<&str>) -> Result<Self>

Create a new configuration.

§Example

use languages_rs::Config;

let config: Config = match Config::new("languages", vec!["en"]) {
    Ok(config) => config,
    Err(e) => {
        eprintln!("Error: {}", e);
        return;
    },
};

Source

pub fn default() -> Result<Self>

Get the default configuration.

§Default

{
    "directory": "languages/",
    "languages": []

§Example

use languages_rs::Config;

let config: Config = match Config::default() {
    Ok(config) => config,
    Err(e) => {
        eprintln!("Error: {}", e);
        return;
    },
};

Source

pub fn get_directory(&self) -> String

Get the languages directory.

§Example

use std::{env, path};

use languages_rs::Config;

let config = Config::default().unwrap();
assert_eq!(
    config.get_directory(),
    format!(
        "{}{}languages",
        env::current_dir().unwrap().display(),
        path::MAIN_SEPARATOR,
    ),
);

Source

pub fn set_directory(&mut self, new_directory: &str) -> Result<()>

Change the languages directory.

§Example

use std::env;

use languages_rs::Config;

let mut config = Config::default().unwrap();
assert!(config.set_directory("languages").is_ok());

Source

pub fn get_languages(&self) -> Vec<String>

Get the availables languages.

§Example

use languages_rs::Config;

let config = Config::default().unwrap();
assert_eq!(config.get_languages(), Vec::<String>::new());

Source

pub fn add_language(&mut self, language: String) -> Result<()>

Add a new language to the languages list if it does not exist.

§Example

use languages_rs::Config;

let mut config = Config::default().unwrap();
assert_eq!(config.get_languages(), Vec::<String>::new());
assert!(config.add_language(String::from("en")).is_ok());
assert_eq!(config.get_languages(), vec![String::from("en")]);
