Enum HandlerAction 

pub enum HandlerAction {
    Continue,
    Exit,
    Undo,
}

The action of a DECLARE … HANDLER — what happens after the handler body runs.

A tag (no meta): the keyword’s span is subsumed by the enclosing Declaration::Handler, exactly as super::TriggerTiming rides its parent’s span.

Variants

Continue

CONTINUE — resume execution after the statement that raised the condition.

Exit

EXIT — leave the compound block the handler is declared in.

Undo

UNDO — roll back and leave (parsed for completeness; the server restricts it).
