A design pattern for shared library loading in Rust with versioned vtables and owned symbols

This repository contains an example design pattern for interfacing with C-language plugins through Rust. It works on UNIX-based systems only.

For an explanation of the code, see the corresponding blog post at http://kmdouglass.github.io/posts/a-simple-plugin-interface-for-the-rust-ffi/

Instructions

First, from the root of this repository, build the example C library:

$ cd ffi-test
$ make

Next, build the Rust binary and run it:

$ cd ..
$ cargo build
$ cargo run
