Expand description

Used to call arbitrary code on state changes.

§Example

#[derive(Debug, Clone)]
enum Message {
    Foo,
    Bar,
}
 
#[vin::actor]
#[vin::handles(Message)]
struct MyActor;
 
#[async_trait]
impl vin::Hooks for MyActor {
    async fn on_started(&self) {
        println!("Started!");
    }
}
