Enum FocusRequestError 

pub enum FocusRequestError {
    NotAttached,
    NoFocusTarget,
}

Why FocusRequester::request_focus could not move focus.

Variants

NotAttached

The requester has never been attached to a node via Modifier::focus_requester, or the node it was attached to has since left composition.

NoFocusTarget

The requester’s node is attached, but nothing on it — no Modifier::focus_target, no Modifier::on_focus_changed, no text field — is registered to receive focus.
