Rust json format

Rust JSON localization format is used by Rust applications that prefer JSON over YAML for locale files. JSON-based Rust i18n solutions typically follow the same key-value structure as JavaScript i18n JSON files but are loaded and processed within the Rust build or runtime environment.

Rust JSON locale files are valid JSON objects mapping string keys to string values. Nested objects provide namespace hierarchies. Interpolation variable syntax depends on the specific Rust i18n crate in use. Some crates use double-brace syntax, others use custom delimiters.

Best practice: use the crate's include_i18n macro or equivalent to load locale files at compile time where possible — compile-time loading catches missing keys before deployment rather than at runtime. Keep JSON locale files in a dedicated localization directory and version them alongside your application source. Language Monster supports Rust JSON format and preserves the key structure through translation.
