[−][src]Struct bevy::app::EventReader
Reads events of type T in order and tracks which events have already been read.
Implementations
impl<T> EventReader<T>[src]
pub fn iter(&mut self, events: &'a Events<T>) -> impl DoubleEndedIterator[src]
Iterates over the events this EventReader has not seen yet. This updates the EventReader's event counter, which means subsequent event reads will not include events that happened before now.
pub fn latest(&mut self, events: &'a Events<T>) -> Option<&'a T>[src]
Retrieves the latest event that this EventReader hasn't seen yet. This updates the EventReader's event counter, which means subsequent event reads will not include events that happened before now.
pub fn find_latest(
&mut self,
events: &'a Events<T>,
predicate: impl FnMut(&&T) -> bool
) -> Option<&'a T>[src]
&mut self,
events: &'a Events<T>,
predicate: impl FnMut(&&T) -> bool
) -> Option<&'a T>
Retrieves the latest event that matches the given predicate that this reader hasn't seen yet. This updates the EventReader's
event counter, which means subsequent event reads will not include events that happened before now.
pub fn earliest(&mut self, events: &'a Events<T>) -> Option<&'a T>[src]
Retrieves the earliest event in events that this reader hasn't seen yet. This updates the EventReader's
event counter, which means subsequent event reads will not include events that happened before now.
