Trait EventSubscriber

pub trait EventSubscriber {
    // Required methods
    fn process(&self, events: Events, ops: &mut EventOps<'_>);
    fn init(&self, ops: &mut EventOps<'_>);
}

Allows the interaction between an EventManager and different event subscribers that do not require a &mut self borrow to perform init and process.

Any type implementing this also trivially implements MutEventSubscriber. The main role of EventSubscriber is to allow wrappers such as Arc and Rc to implement EventSubscriber themselves when the inner type is also an implementor.

Required Methods

fn process(&self, events: Events, ops: &mut EventOps<'_>)

Process events triggered in the event manager loop.

Optionally, the subscriber can use ops to update the events it monitors.

fn init(&self, ops: &mut EventOps<'_>)

Initialization called by the EventManager when the subscriber is registered.

The subscriber is expected to use ops to register the events it wants to monitor.
