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}"));
}
}
