A recent article on Dev.to explores a simple way to implement i18n (internationalization) support in Rust. The solution leverages Rust's OnceCell and Mutex features to manage translations stored in JSON files, caching them in memory for efficient retrieval. This approach ensures thread-safety and reduces disk access, making it suitable for multi-threaded applications.

The article provides a code snippet for the Translator struct, which allows developers to load and retrieve translation data using a hierarchical HashMap structure. The solution also supports variable replacement, enabling dynamic values to be inserted into translations.
