## Description

ICU4X is a modular internationalization library written in Rust, designed as a cross-platform toolkit for formatting text, dates, numbers, and identifiers according to specific regional and cultural rules. It decomposes internationalization features into independent micro-libraries and embeds optimized binary structures directly into application binaries during the build phase via compile-time code generation, or loads externalized cultural datasets dynamically on demand. 

The library utilizes zero-allocation data structuring to access internationalization properties directly from serialized buffers without parsing or allocating dynamic heap memory at runtime. To support diverse platforms, it features automated foreign function interface export to generate multi-language wrappers, allowing safe native execution across multiple host programming environments.
