Rust library integration will be described based on BLAKE3 hash-function integration.
The first step is forking a library and making necessary changes for Rust and C/C++ compatibility.
The first step of integration is to add the library to /rust folder. To do this, you need to create an empty Rust project and include the required library in Cargo.toml. It is also necessary to configure new library compilation as static by adding `crate-type = ["staticlib"]` to Cargo.toml.
After forking library repository you need to change target settings in Cargo.toml file. Firstly, you need to switch build to static library. Secondly, you need to add cbindgen crate to the crate list. We will use it later to generate C-header automatically.
Next, you need to link the library to CMake using Corrosion library. The first step is to add the library folder in the CMakeLists.txt inside the /rust folder. After that, you should add the CMakeLists.txt file to the library directory. In it, you need to call the Corrosion import function. These lines were used to import BLAKE3:
The next step is creating or editing the build.rs script for your library - and enable cbindgen to generate the header during library build. These lines were added to BLAKE3 build script for the same purpose:
```
corrosion_import_crate(MANIFEST_PATH Cargo.toml NO_STD)
target_include_directories(_ch_rust_blake3 INTERFACE include)
add_library(ch_rust::blake3 ALIAS _ch_rust_blake3)
```
Thus, we will create a correct CMake target using Corrosion, and then rename it with a more convenient name. Note that the name `_ch_rust_blake3` comes from Cargo.toml, where it is used as project name (`name = "_ch_rust_blake3"`).
Since Rust data types are not compatible with C/C++ data types, we will use our empty library project to create shim methods for conversion of data received from C/C++, calling library methods, and inverse conversion for output data. For example, this method was written for BLAKE3:
```
#[no_mangle]
pub unsafe extern "C" fn blake3_apply_shim(
begin: *const c_char,
_size: u32,
out_char_data: *mut u8,
) -> *mut c_char {
if begin.is_null() {
let err_str = CString::new("input was a null pointer").unwrap();
return err_str.into_raw();
}
let mut hasher = blake3::Hasher::new();
let input_bytes = CStr::from_ptr(begin);
let input_res = input_bytes.to_bytes();
hasher.update(input_res);
let mut reader = hasher.finalize_xof();
reader.fill(std::slice::from_raw_parts_mut(out_char_data, blake3::OUT_LEN));
std::ptr::null_mut()
}
```
This method gets C-compatible string, its size and output string pointer as input. Then, it converts C-compatible inputs into types that are used by actual library methods and calls them. After that, it should convert library methods' outputs back into C-compatible type. In that particular case library supported direct writing into pointer by method fill(), so the conversion was not needed. The main advice here is to create less methods, so you will need to do less conversions on each method call and won't create much overhead.
It is worth noting that the `#[no_mangle]` attribute and `extern "C"` are mandatory for all such methods. Without them, it will not be possible to perform a correct C/C++-compatible compilation. Moreover, they are necessary for the next step of the integration.
After writing the code for the shim methods, we need to prepare the header file for the library. This can be done manually, or you can use the cbindgen library for auto-generation. In case of using cbindgen, you will need to write a build.rs build script and include cbindgen as a build-dependency.
An example of a build script that can auto-generate a header file:
```
let crate_dir = env::var("CARGO_MANIFEST_DIR").unwrap();

}
```
As you can see, script sets the output directory and launches header generation.
The next step is to add CMake files into library directory, so it can build with other submodules. As you can see, BLAKE3 main directory contains two CMake files - CMakeLists.txt and build_rust_lib.cmake. The second one is a function, which calls cargo build and sets all needed paths for library build. You should copy it to your library and then you can adjust cargo flags and other settings for you library needs.
When finished with CMake configuration, you should move on to create a C/C++ compatible API for your library. Let us see BLAKE3's method blake3_apply_shim:
```
#[no_mangle]
pub unsafe extern "C" fn blake3_apply_shim(
begin: *const c_char,
_size: u32,
out_char_data: *mut u8,
) -> *mut c_char {
if begin.is_null() {
let err_str = CString::new("input was a null pointer").unwrap();
return err_str.into_raw();
}
let mut hasher = Hasher::new();
let input_bytes = CStr::from_ptr(begin);
let input_res = input_bytes.to_bytes();
hasher.update(input_res);
let mut reader = hasher.finalize_xof();
reader.fill(std::slice::from_raw_parts_mut(out_char_data, OUT_LEN));
std::ptr::null_mut()
}
```
This method gets C-compatible string, its size and output string pointer as input. Then, it converts C-compatible inputs into types that are used by actual library methods and calls them. After that, it should convert library methods' outputs back into C-compatible type. In that particular case library supported direct writing into pointer by method fill(), so the conversion was not needed. The main advice here is to create less methods, so you will need to do less conversions on each method call and won't create much overhead.
Also, you should use attribute #[no_mangle] and `extern "C"` for every C-compatible attribute. Without it library can compile incorrectly and cbindgen won't launch header autogeneration.
After all these steps you can test your library in a small project to find all problems with compatibility or header generation. If any problems occur during header generation, you can try to configure it with cbindgen.toml file (you can find an example of it in BLAKE3 directory or a template here: [https://github.com/eqrion/cbindgen/blob/master/template.toml](https://github.com/eqrion/cbindgen/blob/master/template.toml)). If everything works correctly, you can finally integrate its methods into ClickHouse.

In addition, some problems with integration are worth noting here:
1) Some architectures may require special cargo flags or build.rs configurations, so you may want to test cross-compilation for different platforms first.
2) MemorySanitizer can cause false-positive reports as it's unable to see if some variables in Rust are initialized or not. It was solved with writing a method with more explicit definition for some variables, although this implementation of method is slower and is used only to fix MemorySanitizer builds.

Интеграция библиотек будет описываться на основе работы проведенной для библиотеки BLAKE3.
Первым шагом интеграции является создание форка библиотеки для внесения дальнейших изменений по совместимости методов на Rust с C/C++.
Первым шагом интеграции является добавление библиотеки в папку /rust. Для этого необходимо создать в папке пустой Rust-проект, подключив в Cargo.toml нужную библиотеку. Также необходимо компилировать новую библиотеку как статическую, для этого необходимо добавить `crate-type = ["staticlib"]` в Cargo.toml.
В форке необходимо будет изменить конфигурацию Cargo.toml, сменив таргет на статическую библиотеку. Кроме того, необходимо добавить crate cbindgen для его дальнейшего использования при сборке.
Далее необходимо подключить библиотеку к CMake. Для этого в ClickHouse была подключена библиотека Corrosion. Первым шагом является подключение папки с новой библиотекой в корневом CMakeLists.txt папки /rust. После этого следует добавить в директорию с библиотекой файл CMakeLists.txt, в котором будет вызвана функция из Corrosion. Как пример, приведем файл из BLAKE3:
Необходимо создать либо отредактировать сборочный скрипт build.rs, добавив в него запуск cbindgen - автогенератора заголовочных файлов .h. Пример такого запуска можно увидеть в build.rs для BLAKE3:
```
corrosion_import_crate(MANIFEST_PATH Cargo.toml NO_STD)
target_include_directories(_ch_rust_blake3 INTERFACE include)
add_library(ch_rust::blake3 ALIAS _ch_rust_blake3)
```
Таким образом, мы создадим при помощи Corrosion корректный CMake-таргет, а затем переобозначим его более понятным именем. Стоит отметить, что имя `_ch_rust_blake3` происходит из Cargo.toml, где оно выступает в качестве имени проекта (`name = "_ch_rust_blake3"`).
Поскольку типы данных Rust не совместимы с типами данных C/C++, то в проекте мы опишем интерфейс для методов-прослоек, которые будут преобразовывать данные, получаемые из C/C++, вызывать методы библиотеки, а затем делать преобразование возвращаемых обратно данных. В частности, рассмотрим такой метод, написанный для BLAKE3:
```
#[no_mangle]
pub unsafe extern "C" fn blake3_apply_shim(
begin: *const c_char,
_size: u32,
out_char_data: *mut u8,
) -> *mut c_char {
if begin.is_null() {
let err_str = CString::new("input was a null pointer").unwrap();
return err_str.into_raw();
}
let mut hasher = blake3::Hasher::new();
let input_bytes = CStr::from_ptr(begin);
let input_res = input_bytes.to_bytes();
hasher.update(input_res);
let mut reader = hasher.finalize_xof();
reader.fill(std::slice::from_raw_parts_mut(out_char_data, blake3::OUT_LEN));
std::ptr::null_mut()
}
```
На вход метод принимает строку в C-совместимом формате, её размер и указатель, в который будет положен результат. Кроме того, для того, чтобы иметь возможность вывести ошибку, метод возвращает строку с ней как результат работы (и нулевой указатель в случае отсутствия ошибок). C-совместимые не используются в методах BLAKE3, поэтому они конвертируются посредством соотвествующих структур и методов в привычные форматы для языка Rust. Далее запускаются оригинальные методы библиотеки. Их результат следует преобразовать обратно в C-совместимые структуры, однако в данном случае удается избежать обратной конвертации, поскольку библиотека поддерживает запись напрямую по указателю *mut u8.
Кроме того, стоит отметить обязательность аттрибута #[no_mangle] и указания extern "C" для всех таких методов. Без них не удастся провести корректную совместимую с C/C++ компиляцию. Кроме того, они необходимы для следующего этапа подключения библиотеки.
После написания кода методов-прослоек нам необходимо подготовить заголовочный файл для библиотеки. Это можно сделать вручную, либо воспользоваться библиотекой cbindgen для автогенерации. В случае с использованием cbindgen, нам понадобится написать сборочный скрипт build.rs и подключить cbindgen в качестве build-dependency.
Пример сборочного скрипта, которым можно автосгенерировать заголовочный файл:
```
let crate_dir = env::var("CARGO_MANIFEST_DIR").unwrap();
@ -28,39 +67,7 @@ slug: /ru/development/integrating_rust_libraries
}
```
Скрипт назначает директорию для создания залоговочного файла и в конце запускает метод генерации cbindgen.
Если возникают пробемы с генерацией заголовков, может потребоваться поработать с конфигурацией cbindgen через файл cbindgen.toml, взяв оригинальный темплейт разработчика cbindgen: [https://github.com/eqrion/cbindgen/blob/master/template.toml](https://github.com/eqrion/cbindgen/blob/master/template.toml).
Далее необходимо подключить библиотеку к CMake. В BLAKE3 для этого были созданы два файла - CMakeLists.txt и файл, содержащий функцию для запуска cargo build как таргета, - build_rust_lib.cmake. Последний стоит скопировать в подключаемую библиотеку и отредактировать в соотвествии с требуемыми параметрами для сборки - добавить флаги или какие-либо настройки для разных архитектур.
Завершив настройку CMake, можно приступить к созданию методов-прослоек, которые обеспечат совместимость библиотеки и остального кода ClickHouse. В частности, рассмотрим такой метод, написанный для BLAKE3:
```
#[no_mangle]
pub unsafe extern "C" fn blake3_apply_shim(
begin: *const c_char,
_size: u32,
out_char_data: *mut u8,
) -> *mut c_char {
if begin.is_null() {
let err_str = CString::new("input was a null pointer").unwrap();
return err_str.into_raw();
}
let mut hasher = Hasher::new();
let input_bytes = CStr::from_ptr(begin);
let input_res = input_bytes.to_bytes();
hasher.update(input_res);
let mut reader = hasher.finalize_xof();
reader.fill(std::slice::from_raw_parts_mut(out_char_data, OUT_LEN));
std::ptr::null_mut()
}
```
На вход метод принимает строку в C-совместимом формате, её размер и указатель, в который будет положен результат. Кроме того, для того, чтобы иметь возможность вывести ошибку, метод возвращает строку с ней как результат работы (и нулевой указатель в случае отсутствия ошибок). C-совместимые не используются в методах BLAKE3, поэтому они конвертируются посредством соотвествующих структур и методов в привычные форматы для языка Rust. Далее запускаются оригинальные методы библиотеки. Их результат следует преобразовать обратно в C-совместимые структуры, однако в данном случае удается избежать обратной конвертации, поскольку библиотека поддерживает запись напрямую по указателю *mut u8.
Кроме того, стоит отметить обязательность аттрибута #[no_mangle] и указания extern "C" для всех таких методов. Без них не удастся провести корректную совместимую с C/C++ компиляцию и автогенерацию заголовков.
После этих действий можно протестировать компиляцию и работу методов на небольшом проекте для выявляения несовместимостей и ошибок. Если возникают пробемы с генерацией заголовков, может потребоваться поработать с конфигурацией cbindgen через файл cbindgen.toml, найти который можно либо в BLAKE3, либо взяв оригинальный темплейт разработчика cbindgen: [https://github.com/eqrion/cbindgen/blob/master/template.toml](https://github.com/eqrion/cbindgen/blob/master/template.toml).
В заключение, стоит отметить пару пробелм, возникших при интеграции BLAKE3:
1) Некоторые архитектуры могут потребовать настройки компиляции в build.rs и в build_rust_lib.cmake в связи со своими особенностями.
2) MemorySanitizer плохо понимает инициализацию памяти в Rust, поэтому для избежания ложноположительных срабатываний для BLAKE3 был создан альтернативный метод, который более явно, но при этом медленнее, инициализировал память. Он компилируется только для сборки с MemorySanitizer и в релиз не попадает. Вероятно, возможны и более красивые способы решения этой проблемы, но при интеграции BLAKE3 они не были обнаружены.
В заключение, стоит отметить проблему, с которой пришлось столкнуться при интеграции BLAKE3:
