BITPACK_DERIVED_FIELD_CONST_FOR_TYPE

#define BITPACK_DERIVED_FIELD_CONST_FOR_TYPE	(		Type,
			c )

Value:

BITPACK_DERIVED_FIELD_INFO_FOR_TYPE(Type, [](auto &fi) { fi.isConst = c; })

Modify the constness field information for a type in a derived bitpack.

This is a thin wrapper around BITPACK_DERIVED_FIELD_INFO_FOR_TYPE.

BITPACK_DERIVED_FIELD_INFO_FOR_TYPE

#define BITPACK_DERIVED_FIELD_INFO_FOR_TYPE	(		Type,
			lambda )

Value:

template<>                                                                 \

      std::is_invocable_r_v<void, decltype(lambda), FieldInfo &>);         \
    auto fi = ParentBitpack::field_info_for_type<Type>();                  \
    lambda(fi);                                                            \
    return fi;                                                             \
}

Modify the field information for a type in a derived bitpack.

BITPACK_DERIVED_PREFIX

#define BITPACK_DERIVED_PREFIX

Value:

using BitpackDerived<ParentBitpack>::BitpackDerived;                       \
using BitpackDerived<ParentBitpack>::operator=;                            \
/* Inherit field info for most types from parent bitpack */                \
template<typename FieldType>                                               \
static constexpr FieldInfo field_info_for_type()                           \
{                                                                          \
    return ParentBitpack::field_info_for_type<FieldType>();                \
}

Capture the incantations often at the top of a BitpackDerived structure.

especially one with type-directed field proxys.
