# C-friendly FFI Design
|
|
|
|
This document is a guide for authoring Rust libraries that expose a C-friendly FFI
|
|
and distributing them as ordinary CMake/pkg-config packages. It covers how to design
|
|
C-friendly FFI signatures, how to pass primitive types, enums, strings and
|
|
Rust-specific constructs such as `Option` and `Result` across the boundary, and how
|
|
to write the accompanying C/C++ header files.
