Function rdev::listen

pub fn listen<T>(callback: T) -> Result<(), ListenError> where
    T: FnMut(Event) + 'static, 

Listening to global events. Caveat: On MacOS, you require the listen loop needs to be the primary app (no fork before) and need to have accessibility settings enabled.

use rdev::{listen, Event};

fn callback(event: Event) {
    println!("My callback {:?}", event);
    match event.name{
        Some(string) => println!("User wrote {:?}", string),
        None => ()
    }
}
fn main(){
    // This will block.
    if let Err(error) = listen(callback) {
        println!("Error: {:?}", error)
    }
}
