## What it is
Corrosion is a tool for integrating Rust into existing CMake projects, automatically importing Rust executables, static libraries, and dynamic libraries as CMake targets. It simplifies linking Rust and C/C++ code in a single build, including cross-compilation scenarios.

## Use cases
- build a C++ project that links a Rust library
- integrate Rust crates into an existing CMake build system
- import Rust executables and libraries as CMake targets
- cross-compile a mixed Rust and C/C++ codebase
- link C/C++ libraries into a Rust executable built with CMake
- replace manual cargo invocations in CMake builds

## When to choose
- you have an existing CMake project and want to add Rust components
- you need Rust and C/C++ code built together with one build system
- you want simple cross-compilation of mixed Rust/C++ projects

## When to avoid
- your project is pure Rust and can use Cargo directly
- your build system is not CMake (e.g. Bazel, Meson, Make)
- you only need to call Rust tools from scripts rather than integrate builds

## Facets
- artifact type: cli-tool

- function: build-tool, developer-tools
- domain: developer-tools, cross-platform, programming-languages
- platform: cross-platform, cpp, rust
