}

An Element that has been rendered and allows reading and modifying information about it.

Different platforms will have different implementations and different levels of support for this trait. Renderers that do not support specific features will return None for those queries.

Required Methods

fn as_any(&self) -> &(dyn Any + 'static)

return self as Any

Provided Methods

fn get_client_rect( &self ) -> Pin<Box<dyn Future<Output = Result<Rect<f64, f64>, MountedError>>>>

Get the bounding rectangle of the element relative to the viewport (this does not include the scroll position)

fn scroll_to( &self, _behavior: ScrollBehavior ) -> Pin<Box<dyn Future<Output = Result<(), MountedError>>>>

Scroll to make the element visible

fn set_focus( &self, _focus: bool ) -> Pin<Box<dyn Future<Output = Result<(), MountedError>>>>

Set the focus on the element
