Enum ChoiceAction 

#[non_exhaustive]
pub enum ChoiceAction {
    Shift(usize),
    Reduce(usize),
}

A merged choices() entry — Lark returns the raw states[position] map whose keys include NON-TERMINAL goto names: hyperlark re-merges the split token_actions/goto_actions rows to reproduce it.

Provisional: part of the interactive recovery surface, so #[non_exhaustive] leaves room for a future goto/shift split without a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Shift(usize)

Shift to (terminal key) or goto (rule-name key) this state.

Reduce(usize)

Reduce by this rule index (terminal keys only).
