pub fn cpp_comparable_parameter_shapes<'tree>(
function_declarator: Node<'tree>,
source: &str,
ancestry: &ParentIndex<'tree>,
) -> Vec<CppComparableSlot>Expand description
The comparable shape of each invocation parameter, in declaration order.
The result is index-parallel with
cpp_callable_parameter_type_identities; a parameter that admits no
comparable shape is CppComparableSlot::Unstructured, which a comparison
must treat as evidence of nothing rather than as agreement.
