dlopen2

[

This is a fork of the original, now unmaintained dlopen with updated dependencies, bug fixes and some new features.

Overview

This library is my effort to make use of dynamic link libraries in Rust simple. Previously existing solutions were either unsafe, provided huge overhead of required writing too much code to achieve simple things. I hope that this library will help you to quickly get what you need and avoid errors.

Quick example

use dlopen2::wrapper::{Container, WrapperApi};
use hotload::types::Hotload;

#[derive(WrapperApi)]
struct MyApi {
    test_print: fn(msg: String),
    init_data: fn(msg: String),
    stop_runtime: fn(),
}

fn main(){
    let dll: Hotload<MyApi> = Hotload::new("../call_lib/target/release/call_lib.dll");
    dll.init_load().unwrap();

    let mut count = 0;
    loop {
        count += 1;
        dll.test_print(format!("msg{count}"));
    }
}
