I want to use a mutable object in callback.
I want to write a code like this:
let mut handler = Handler::new(6); if let Err(error) = grab(move |event| { handler.callback(event) }) { println!("Error: {:?}", error) } struct Handler { buffer: VecDeque<Key>, capacity: usize, modifiers: HashSet<Modifier>, } impl Handler { fn new(capacity: usize) -> Handler { Handler { buffer: VecDeque::with_capacity(capacity), capacity, modifiers: HashSet::new(), } } fn callback(&mut self, event: Event) -> Option<Event> { // implement here. } }
Hi ! Any news about this PR ?
I need grab callback to be FnMut too.
