Struct Event 

pub struct Event<EVT: 'static + Send + Sync> { /* private fields */ }

Container for event. The main purpose of this container is to ensure correct order of events. Asyncronous send_event function finishes only when all copies of Event are destroyed. This allows to guarantee that sent event have been processed by all handlers by the moment when send_event returns.

Event object is created as output of EventStream. There is no other way to create it.

Function which handles Event object may produce new events by calling send_event. Sometimes it’s necessary to ensure that these derived events are handled before new instance of source event is produced. For example if mouse click produces button press event, we have to be sure that button press event is handled before next mouse click arrives. To do it the second parameter source of send_event is used. Reference to source event is stored into sent event.

Trait Implementations

impl<EVT: 'static + Send + Sync> AsRef<EVT> for Event<EVT>

fn as_ref(&self) -> &EVT

Converts this type into a shared reference of the (usually inferred) input type.

impl<EVT: 'static + Send + Sync> Clone for Event<EVT>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<EVT: 'static + Send + Sync> Into<Option<Arc<EventBox>>> for Event<EVT>

fn into(self) -> Option<Arc<EventBox>>

Converts this type into the (usually inferred) input type.
