Cpp2Rust is a tool that automatically translates C++ to safe Rust using clang's AST. It simplifies the translation process with a runtime library while allowing configurations for safe or unsafe Rust code generation.
Cpp2Rust is a new tool designed to automate the translation of C++ code into safe Rust code. This is important as it allows developers to leverage Rust's safety features without rewriting C++ code manually. The tool’s approach enhances code safety by utilizing Rust's ownership model.
Cpp2Rust uses a syntax-driven translation process based on the Abstract Syntax Tree (AST) generated by Clang. It begins by parsing C++ files and traverses the AST to emit Rust code, where necessary, including calls to the libcc2rs runtime library to manage raw pointer semantics.
The translator's default output is safe Rust employing a reference counting model, but developers can switch to an unsafe model for performance comparisons and debugging purposes using the command line. This flexibility is crucial for developers who need to balance safety with performance in different scenarios.
Cpp2Rust can be easily installed on Ubuntu using a few command-line instructions to install required dependencies and build the project. For example, after setting up, users can run simple commands like: ./build/cpp2rust/cpp2rust --file=<file>.cpp -o=<file>.rs to convert C++ code into Rust.
Cpp2Rust includes functionality for testing the output, allowing users to run all tests, unit tests, and checks for specific components of the libcc2rs library. This ensures that the translated code adheres to intended behaviors and safety requirements.
