Webb18 apr. 2024 · Rust was designed with its FFI (Foreign Function Interface) in mind so it allows cheap (or even zero cost) interoperability with C and C++. For both solutions (plain C and C++), I’ll demonstrate that we can call C/C++ and Rust code back and forth (pass Rust callback to C++ code). I’ll focus on performance, flexibility, and limitations too. Webb11 juni 2024 · C function declarations are necessary to link the external library (at runtime) compiled with Rust.
