通过 FFI【1】 传递复杂数据结构【2】的技巧：在 Scheme【3】 语言中调用 Rust【4】 库

在软件开发中，不同语言之间的交互是常见的需求。FFI（Foreign Function Interface，外部函数接口）提供了一种在语言之间进行交互的方法。本文将探讨如何在 Scheme 语言中使用 FFI 调用 Rust 库，并重点介绍如何传递复杂数据结构。

FFI 简介

FFI 是一种允许不同语言编写的程序相互调用的机制。在 FFI 中，一个语言可以调用另一个语言编写的函数。在 Scheme 语言中，FFI 通常用于调用 C 或 C++ 库。

Scheme 语言中的 FFI

在 Scheme 语言中，可以使用 `foreign-definition【5】` 和 `foreign-procedure【6】` 语法来定义和使用 FFI 函数。

定义 FFI 函数
