How to use Rust's Foreign Function Interface
Dec 27, 2024
Rust's Foreign Function Interface (FFI) allows Rust code to interact with code written in other programming languages, such as C. In this article, we will explore Rust's FFI capabilities by building a program that interfaces with a C library using Rust's FFI. Specifically, we will use Rust to call a C library function that computes the sum of two integers.
