Creates the element with all of the required parameters set to use this device.

name

Returns

a new Element configured to use this device

fn reconfigure_element(&self, element: &Element) -> Result<(), LoggableError>

Tries to reconfigure an existing element to use the device. If this function fails, then one must destroy the element and create a new one using DeviceExt::create_element().
