Implementations

impl EventListenerKey

pub fn extract<'a>(&self, event: &'a Event) -> Option<&'a (dyn Any + 'static)>

Extract the relevant event data if this listener matches the event

Trait Implementations

impl Clone for EventListenerKey

fn clone(&self) -> EventListenerKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventListenerKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for EventListenerKey

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EventListenerKey

fn eq(&self, other: &EventListenerKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
