1# icu_capi [](https://crates.io/crates/icu_capi) 2 3<!-- cargo-rdme start --> 4 5This crate contains the source of truth for the [Diplomat](https://github.com/rust-diplomat/diplomat)-generated 6FFI bindings. This generates the C, C++, JavaScript, and TypeScript bindings. This crate also contains the `extern "C"` 7FFI for ICU4X. 8 9While the types in this crate are public, APIs from this crate are *not intended to be used from Rust* 10and as such this crate may unpredictably change its Rust API across compatible semver versions. The `extern "C"` APIs exposed 11by this crate, while not directly documented, are stable within the same major semver version, as are the bindings exposed under 12the `cpp/` and `js/` folders. 13 14This crate may still be explored for documentation on docs.rs, and there are language-specific docs available as well. 15C++, Dart, and TypeScript headers contain inline documentation, which is available pre-rendered: [C++], [TypeScript]. 16 17This crate is `no_std`-compatible. If you wish to use it in `no_std` mode, you must write a wrapper crate that defines an allocator 18and a panic hook in order to compile as a C library. 19 20More information on using ICU4X from C++ can be found in [our tutorial]. 21 22[our tutorial]: https://github.com/unicode-org/icu4x/blob/main/tutorials/cpp.md 23[TypeScript]: https://unicode-org.github.io/icu4x/tsdoc 24[C++]: https://unicode-org.github.io/icu4x/cppdoc 25 26<!-- cargo-rdme end --> 27 28## More Information 29 30For more information on development, authorship, contributing etc. please visit [`ICU4X home page`](https://github.com/unicode-org/icu4x). 31
