Marrying Rust and CMake - Easy Rust and C/C++ Integration!

Corrosion

Corrosion, formerly known as cmake-cargo, is a tool for integrating Rust into an existing CMake project. Corrosion can automatically import executables, static libraries, and dynamic libraries from a workspace or package manifest (Cargo.toml file).

Features

• Automatic Import of Executable, Static, and Shared Libraries from Rust Crate
• Easy Installation of Rust Executables
• Trivially Link Rust Executables to C/C++ Libraries in Tree
• Multi-Config Generator Support
• Simple Cross-Compilation

Sample Usage with FetchContent

Using the CMake FetchContent module allows you to easily integrate corrosion into your build. Other methods including installing corrosion or adding it as a subdirectory are covered in the setup chapter of the corrosion documentation.
