## 项目历史与用法

C2Rust is a C99-to-Rust migration toolkit. Its core transpiler produces unsafe Rust that closely mirrors the original C so functionality and tests can be preserved before humans or refactoring tools gradually improve the Rust.

### 项目历史

The upstream Git history begins on 22 June 2017 with original C sources, Corrode-generated Rust sources, and early source-rewriting work. The README describes the project's goal as helping migrate C99-compliant code to Rust while preserving behavior first.

By the time of the README's RustConf 2018 reference, C2Rust had become a visible example of pragmatic Rust adoption for existing C codebases. The project grew beyond raw transpilation to include cross-checking translated code against the original and a refactoring tool intended to reduce the manual work of turning unsafe Rust into safer, more idiomatic Rust.

### 采用历史

C2Rust is packaged both as a Rust crate installed with `cargo install --locked c2rust` and through system package managers such as Homebrew and Alpine according to source_facts. The README also documents direct Git installation for users needing unreleased bug fixes.

Adoption is mostly by developers facing migration or audit work rather than everyday end users. Its requirement for LLVM/clang, compile_commands.json, and close build-system integration places it in the serious-codebase-migration category.

### 使用方式

For non-trivial projects, C2Rust expects a `compile_commands.json` compilation database so libclangTooling can see the same compiler arguments used by the original C build. Users run `c2rust transpile path/to/compile_commands.json`, optionally emitting Cargo build files or specifying binary entry points.

The README also documents trivial source-file transpilation, cross-checking translated code against the original, and `c2rust refactor` tooling for follow-up transformations. Developers often need LLVM_CONFIG_PATH or related environment variables when building against specific LLVM installs.

### 为什么软件包爱好者会关心

C2Rust is significant because it packages one of the hard parts of language migration as a CLI workflow: consume a C build database, produce Rust, run tests, then iterate. It is not magic safe Rust generation; its value is making the first migration step mechanical and reproducible.

It also represents a Rust ecosystem pattern where package-manager installation is only the entry point. Real use depends on compiler toolchains, build-system metadata, test suites, and sometimes pinned nightly Rust components for advanced refactoring tools.
