This library is designed to integrate tantivy into ClickHouse and MyScaleDB.

All FFI (Foreign Function Interface) functions are exposed in lib.rs. Developers need to regenerate the header file after making any changes to the relevant code:

cbindgen . -o include/tantivy_search_cbindgen.h --config cbindgen.toml
cxxbridge src/lib.rs --header > include/tantivy_search_cxx.h

If developers do not add, delete, or modify the names of FFI functions, there is no need to execute the above command.

• Added unit tests in C++ to test Rust FFI functions.
• Add additional unit tests within Rust FFI functions.
• Refactor the tantivy_search code using object-oriented principles.

You can use cargo to build this library, use this command:

cargo build --release

If you need to test FFI function in C++, run:

mkdir build
cd build && cmake ..
make -j

You can use vscode or other compilers to make the build process more elegant.

Test in Rust:

cargo test

Here is an example to run unit test in C++:

cd build/tests/unit_test
./unit_test
