Struct EventRoute 

pub struct EventRoute { /* private fields */ }

Holds the route for a routed event and supports raising an event on that route.

The list of handlers is taken from a per-thread pool and returned to it when the route is dropped (or disposed), so raising an event does not allocate once the pool is warm.

Implementations

impl EventRoute

pub fn new<T: ?Sized>(e: &RoutedEvent<T>) -> Self

Creates a route for a routed event.

pub fn has_handlers(&self) -> bool

Whether the route has any handlers.

pub fn add( &mut self, target: &Ref<Interactive>, handler: RouteHandler, routes: RoutingStrategies, handled_events_too: bool, )

Adds a handler to the route.

pub fn add_class_handler(&mut self, target: &Ref<Interactive>)

Adds a class handler to the route: a marker that makes the class handlers of the event run for target.

pub fn raise_event(&self, source: &Ref<Interactive>, e: &dyn IRoutedEventArgs)

Raises an event along the route.

pub fn dispose(&mut self)

Releases the route’s handler list back to the pool.

Trait Implementations

impl Drop for EventRoute

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
