Struct CascadeOutputs 

pub struct CascadeOutputs<'a> {
    pub source: &'a mut String,
    pub emitted: &'a mut HashSet<String>,
    pub inherited_names: &'a mut Vec<String>,
}

Per-scope outputs the walker mutates.

Fields

source: &'a mut String

Polydat source string the walker appends to.

emitted: &'a mut HashSet<String>

Names the walker has emitted, including any pre-emitted names that flowed in via CascadeInputs::pre_emitted. Grows across the walk’s six steps.

inherited_names: &'a mut Vec<String>

Names whose outputs are inherited from a parent (cascade- extern’d, not this scope’s own iter-coord). The per-scope builder threads this into PolydatMatter::inherited_outputs so compute_own_coordinates excludes them when reporting this scope’s own iteration position.
