i18n-embed

This library contains traits and macros to conveniently embed the output of cargo-i18n into your application binary in order to localize it at runtime.

Currently this library depends on rust-embed to perform the actual embedding of the language files. This may change in the future to make the library more convenient to use.

Optional Features

The i18n-embed crate has the following optional Cargo features:

• desktop-requester
  • Enables a convenience implementation of LanguageRequester trait called DesktopLanguageRequester for the desktop platform (windows, mac, linux),which makes use of the locale_config crate for resolving the current system locale.
• web-sys-requester
  • Enables a convenience implementation of LanguageRequester trait called WebLanguageRequester which makes use of the web-sys crate for resolving the language being requested by the user's web browser in a WASM context.

Example

The following is an example for how to derive the required traits on structs, and localize your binary using this library:

use i18n_embed::{I18nEmbed, LanguageLoader, DesktopLanguageRequester};
use rust_embed::RustEmbed;

#[derive(RustEmbed, I18nEmbed)]
#[folder = "i18n/mo"] // path to the compiled localization resources
struct Translations;

#[derive(LanguageLoader)]
struct MyLanguageLoader;

fn main() {
    let translations = Translations {};
    let language_loader = MyLanguageLoader {};

    // Use the language requester for the desktop platform (linux, windows, mac).
    // There is also a requester available for the web-sys WASM platform called
    // WebLanguageRequester, or you can implement your own.
    let requested_languages = DesktopLanguageRequester::requested_languages();

    i18n_embed::select(&language_loader, &translations, &requested_languages);
}
