Port Coding: missing more tools

[kassane]

• cxx-rs This library provides a safe mechanism for calling C++ code from Rust and Rust code from C++.

• safer_ffi  is a framework that helps you write foreign function interfaces (FFI) without polluting your Rust code with unsafe { ... } code blocks while making functions far easier to read and maintain.

• UniFFI is a tool that automatically generates foreign-language bindings targeting Rust libraries.

• diplomat is a experimental Rust tool for generating FFI definitions allowing many other languages to call Rust code.
