[

Quick example

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

// Generate the following rust calling methods
hotload::gen_rust_no_mangle!((MyApi, "../call_lib/src/lib.rs"));

// #[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 created" or "file rename to" is actively loaded
    dll.init_load(|_, _| {}).unwrap();

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