[−][src]Trait event_manager::EventSubscriber
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.
