Struct FocusEvent 

#[non_exhaustive]
pub struct FocusEvent {
    pub related_target: Option<RawId>,
}

DOM focus event — fired when an element receives focus. Does NOT bubble (use FocusInEvent for bubbling).

Chrome: FocusEvent with type "focus".

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

related_target: Option<RawId>

The node that previously had focus (if any). Uses RawId (not raw u32) — safe, generation-checked reference. Chrome: FocusEvent.relatedTarget returns an EventTarget.
