Enum ComprehensionMode 

pub enum ComprehensionMode {
    Cartesian(Vec<Clause>),
    Union(Vec<Subspace>),
}

How the clauses of a comprehension combine.

See the module-level doc for the detection rule and the motivating examples.

Variants

Cartesian(Vec<Clause>)

One ordered list of clauses; iteration emits the cross product. Cartesian(vec![one_clause]) is the degenerate single-variable form (for_each var in expr).

Union(Vec<Subspace>)

A list of sub-spaces. Each Subspace is one Cartesian list of clauses; iteration emits each sub-space’s product, concatenated in declaration order. Variable names typically repeat across sub-spaces so children see the same binding shape regardless of which sub-space the current tuple came from.
