Enum RegionKind 

pub enum RegionKind {
    RepeatUntilSuccess,
}

Which RegionNode variant a structural query selects.

The discriminant half of RegionNode, so a caller can filter regions without matching a variant it does not intend to destructure. Exhaustive like the IR data enums it mirrors (see the crate docs).

Variants

RepeatUntilSuccess

Repeat-until-success region.
