//! Rust bindings for `libclang`.
//!
//! ## Documentation
//!
//! There are two versions of the documentation, one for the API exposed when
//! linking dynamically or statically and one for the API exposed when linking
//! at runtime (see the
//! [Dependencies](https://github.com/KyleMayes/clang-sys#dependencies) section
//! of the README for more information on the linking options).
//!
//! The only difference between the APIs exposed is that when linking at runtime
//! a few additional types and functions are exposed to manage the loaded
//! `libclang` shared library.
//!
//! * Runtime - [Documentation](https://kylemayes.github.io/clang-sys/runtime/clang_sys)
//! * Dynamic / Static - [Documentation](https://kylemayes.github.io/clang-sys/default/clang_sys)
