Struct FocusHandle 

pub struct FocusHandle(/* private fields */);

A cheap, Copy handle to a focusable widget’s identity, so a caller that has moved the widget into a container (and no longer holds a reference to it) can still drive its focus — e.g. autofocus a hosted editor when its tab activates. Obtain one from the widget (see crate::TextArea::focus_handle).
