Enum CppComparableSlot 

pub enum CppComparableSlot {
    Shape(CppComparableParameter),
    Ellipsis,
    Unstructured,
}

One callable parameter’s comparable shape.

CppParameterType above answers “which type is written here” for a structured model and deliberately records no cv-qualifiers, so it reports the same value for f(char *) and f(const char *). Deciding whether two callable declarations declare one function needs the opposite trade: every cv-qualifier that C++ counts as part of the parameter type must survive, while the two declarations may spell the same type through different qualifications. This slot carries that comparand.

The result is index-parallel with cpp_callable_parameter_type_identities and with the rendered parameter spellings of the same callable.

Variants

Shape(CppComparableParameter)

A declared parameter reduced to its comparable shape.

Ellipsis

A ... pack, which declares no parameter type at all.

Unstructured

A parameter with no comparable reduction, such as a macro-obscured, decltype-computed, or function-pointer parameter.
