Struct EmitDynamicTrigger

pub struct EmitDynamicTrigger<T, Targets = ()>where
    Targets: TriggerTargets,
{ /* private fields */ }

Expand description

Emit a trigger for a dynamic component id. This is unsafe and must be verified manually.

Implementations§

source §

impl<E, Targets> EmitDynamicTrigger<E, Targets>
where Targets: TriggerTargets,

source

pub unsafe fn new_with_id( event_type: ComponentId, event_data: E, targets: Targets, ) -> EmitDynamicTrigger<E, Targets>

Sets the event type of the resulting trigger, used for dynamic triggers

§Safety

Caller must ensure that the component associated with event_type is accessible as E

where T: Any,

source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

source §
