Trait alsa::seq::EventData

pub trait EventData {
    fn has_data(e: EventType) -> bool;
    fn set_data(&self, ev: &mut Event);
    fn get_data(ev: &Event) -> Self;
}

Low level methods to set/get data on an Event. Don't use these directly, use generic methods on Event instead.

Required methods

fn has_data(e: EventType) -> bool

fn set_data(&self, ev: &mut Event)

fn get_data(ev: &Event) -> Self
