Trait typed_html::events::EventHandler

pub trait EventHandler<T: OutputType, E> {
    fn attach(&mut self, target: &Element) -> EventListenerHandle;
    fn render(&self) -> Option<String>;
}

Trait for event handlers.

Required Methods

fn attach(&mut self, target: &Element) -> EventListenerHandle

Build a callback function from this event handler.

Returns None is this event handler can’t be used to build a callback function. This is usually the case if the event handler is a string intended for server side rendering.

fn render(&self) -> Option<String>

Render this event handler as a string.

Returns None if this event handler cannot be rendered. Normally, the only event handlers that can be rendered are string values intended for server side rendering.
