Bindgen
Bindgen is a Rust tool that automatically generates Rust FFI (Foreign Function Interface) bindings to C and C++ libraries. It parses C/C++ header files and produces Rust code that allows safe and efficient interoperability with native code. This enables Rust developers to leverage existing C/C++ libraries without manually writing unsafe bindings.
Developers should use Bindgen when they need to integrate Rust applications with legacy or performance-critical C/C++ libraries, such as system libraries, graphics engines, or hardware interfaces. It is essential for projects like game development, embedded systems, or system programming where Rust's safety features are combined with C/C++ ecosystems, reducing manual effort and potential errors in FFI code.
