Implementations

impl NativeEventHandler

Implementation of event handler construction and invocation.

pub fn create<F>(event_name: &'static str, callback: F) -> Self

where F: FnMut(Event) + 'static,

Creates a new event handler from a static event name string and callback.

Arguments

• &'static str - The event name (e.g., “click”, “input”, “hashchange”).
• FnMut(Event) + 'static - The callback to invoke when the event fires.

Returns

• Self - A new event handler.

pub fn handle(&self, event: Event)

Invokes the underlying callback with the given event.

Arguments

• Event - The event to pass to the callback.
