Diplomat is a multi-language FFI (Foreign Function Interface) tool designed to help Rust libraries like ICU4X expose their APIs to multiple programming languages efficiently. Created to address the challenges of manually writing and maintaining FFI bindings across different languages, it aims to simplify the process of making Rust libraries accessible beyond their native ecosystem. The tool was developed as part of the ICU4X project, which focuses on creating a modular internationalization library for Unicode.
Background
ICU4X is a modular internationalization library written in Rust, designed to bring Unicode support to various programming languages. The challenge of exposing Rust libraries to multiple languages efficiently led to the development of Diplomat as a solution for generating FFI bindings automatically.
