Struct ListenerCallback 

pub struct ListenerCallback<T = ()> { /* private fields */ }

An owned callback type used in AttributeValue::Listener.

This is the type that powers the on attributes in the rsx! macro, allowing you to pass event handlers to elements.

rsx! {
    button {
        onclick: AttributeValue::Listener(ListenerCallback::new(move |evt: Event<MouseData>| {
            // ...
        }))
    }
}

Implementations

impl<T> ListenerCallback<T>

pub fn new<MaybeAsync, Marker>( f: impl FnMut(Event<T>) -> MaybeAsync + 'static, ) -> Self

where T: 'static, MaybeAsync: SpawnIfAsync<Marker>,

Create a new ListenerCallback from a callback

This is expected to be called within a runtime scope. Make sure a runtime is current before calling this method.

pub fn call(&self, event: Event<dyn Any>)

Call the callback with an event

This is expected to be called within a runtime scope. Make sure a runtime is current before calling this method.

pub fn erase(self) -> ListenerCallback

Erase the type of the callback, allowing it to be used with any type of event

Trait Implementations

impl<T> Clone for ListenerCallback<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> IntoAttributeValue for ListenerCallback<T>

fn into_value(self) -> AttributeValue

Convert into an attribute value

impl<T> PartialEq for ListenerCallback<T>

fn eq(&self, other: &Self) -> 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.

impl<T: 'static> SuperFrom<Callback<Event<T>>> for ListenerCallback<T>

fn super_from(input: Callback<Event<T>>) -> Self

Convert from a type to another type.
