std::meta::offset_of

consteval std::meta::member_offset offset_of( std::meta::info r );

Returns the offset of the non-static data member or direct base class represented by r relative to its enclosing class std::meta::parent_of(r).

Parameters

Return value

Let V be the offset in bits from the beginning of a complete object of the type represented by std::meta::parent_of(r) to the subobject associated with what r represents. Returns std::meta::member_offset{V % CHAR_BIT, V % CHAR_BIT}.

Exceptions

Throws std::meta::exception unless r represents one of the following:

• non-static data member
• unnamed bit-field
• direct base class relationship for which either the base class is not a virtual base class or the derived class is not an abstract class
