Function smithay_client_toolkit::output::add_output_listener

pub fn add_output_listener<F: Fn(WlOutput, &OutputInfo, DispatchData<'_>) + Send + Sync + 'static>(
    output: &WlOutput, 
    f: F
) -> OutputListener

Add a listener to this output

The provided closure will be called whenever a property of the output changes, including when it is removed by the compositor (in this case it’ll be marked as obsolete).

The returned OutputListener keeps your callback alive, dropping it will disable the callback and free the closure.
