Struct SubUnitExtractor 

pub struct SubUnitExtractor { /* private fields */ }

Walks a normalized tree and collects the compound structures inside it.

Every node kind that carries a body contributes that body as a candidate sub-unit, and the walk then descends into all children regardless. What varies between kinds is only which child holds the body, so most of them reduce to a lookup; If and Match are the two that do not, because one has an optional second branch and the other has a variable number.

Implementations

impl SubUnitExtractor

pub const fn new(min_node_count: usize) -> Self

pub fn extract(&self, node: &NormalizedNode) -> Vec<SubUnit>

Collect every sub-unit at or below node that meets the node floor.

A node’s own contributions come before its children’s, and children are visited in order, so the result is a pre-order walk.
