Segmentation fault on keypress (OSX)

[red010182]

OS: OSX (Terminal.app has been add to Accessibility->Privacy)

use rdev::{listen, Event};


fn main() {
  // This will block.
  if let Err(error) = listen(callback) {
      println!("Error: {:?}", error)
  }

  fn callback(event: Event) {
      println!("My callback {:?}", event);
      match event.name {
          Some(string) => println!("User wrote {:?}", string),
          None => (),
      }
  }

}

cargo run

Mouse move & click are succesfully listened but whenever I press any key the program exist with

Segmentation fault: 11

i got the same issue, but only if the listen(callback) is invoked in a new thread to make it not blocking (tauri framework) also, i am on osx.

vscode, terminal & app are allowed to listen to keyboard events and so on, i have checked the entire osx settings list

        if let Err(error) = listen(callback) {
            println!("Error: {:?}", error)
        }
    });
}

this is the code

  app.run(|app_handler, run_event| {
        tauri::async_runtime::spawn(async move {
            listen(move |event| match event.event_type {
                EventType::KeyPress(Key::Alt) => {
                    println!("alt")
                }
                _ => {}
            })
            .expect("error");
        });
    });

I had the same issue too (tauri / MacOS / segfault on keypress) But this fixed the problem ✅
