cbindgen
Generates C and C++11 headers from Rust libraries that expose a public C API.
What is cbindgen?
cbindgen is a tool that automatically generates C/C++11 header files for Rust libraries with a public C API. It eliminates the manual and error-prone process of creating these headers by hand, ensuring the generated bindings accurately reflect Rust's type layout and ABI guarantees. The tool supports generating both C and C++ headers from the same Rust library, offering flexibility for different interoperability needs.
Rust developers who need to expose a C-compatible API from their Rust libraries for interoperability with C or C++ codebases, such as those embedding Rust components in larger systems or creating language bindings.
Developers choose cbindgen because it automates header generation with accuracy derived from collaboration with Rust developers, reducing errors and saving time. Its dual-language support allows seamless generation of both C and C++ headers from a single Rust library, providing flexibility without duplication of effort.
