pub struct NativeEventHandler { /* private fields */ }

A wrapper around an event callback.

Stores the event name and a reference-counted mutable closure.

Implementations

impl NativeEventHandler

Implementation of event handler construction, cloning, and invocation.

pub fn new<F>(event_name: NativeEventName, callback: F) -> Self

where F: FnMut(NativeEvent) + 'static,

Creates a new event handler from an NativeEventName enum and callback.

pub fn handle(&self, event: NativeEvent)

Invokes the underlying callback with the given event.

impl NativeEventHandler

pub fn get_event_name(&self) -> &String

pub fn get_mut_event_name(&mut self) -> &mut String

pub fn get_mut_callback(&mut self) -> &mut Rc<RefCell<dyn FnMut(NativeEvent)>>

Trait Implementations

impl Clone for NativeEventHandler

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl IntoCallbackAttribute for NativeEventHandler

Converts an owned event handler into a callback attribute value.

fn into_callback_attribute(self) -> AttributeValue

Converts this value into an AttributeValue, wrapping the callback for use as a component prop.

impl IntoEventAttribute for NativeEventHandler

Converts an owned event handler into an attribute value.

fn into_event_attribute(self) -> AttributeValue

Converts this value into an AttributeValue, or an empty text if None.
