The glue is done using the [cxx crate](https://cxx.rs/) on the Rust side. As a proof-of-concept, only a small console command (`rust_version`) printing the currently used Rust version was added. You can generate and open the Rust documentation using `DDNET_TEST_NO_LINK=1 cargo doc --open`. You can run the Rust tests using `cmake --build <build dir> --target run_rust_tests`, they're automatically included in the `run_tests` target as well. Rust tests don't work on Windows in debug mode on Windows because Rust cannot currently link with the debug version of the C stdlib on Windows: https://github.com/rust-lang/rust/issues/39016. --- The stuff in `src/rust-bridge` is generated using ``` cxxbridge src/engine/shared/rust_version.rs --output src/rust-bridge/engine/shared/rust_version.cpp --output src/rust-bridge/engine/shared/rust_version.h cxxbridge src/engine/console.rs --output src/rust-bridge/cpp/console.cpp --output src/rust-bridge/cpp/console.h ```
