How can I use C++ code in my Rust project?

You can use the cxx crate to create bindings between Rust and C++. It allows you to call C++ code from Rust.

What are the steps to set up the cxx crate?

First, add cxx to your Cargo.toml. Then, create a C++ header file and implement the functions you want to use.

Can you give me an example of a simple C++ function and how to call it in Rust?

Sure! Define a C++ function like int add(int a, int b) { return a + b; } and then use cxx::bridge to call it in Rust.

Are there any performance considerations I should be aware of?

Yes, calling C++ from Rust can introduce overhead. It's best to minimize cross-language calls for performance-critical sections.
