Defined in header <meta>
struct member_offset { std::ptrdiff_t bytes; std::ptrdiff_t bits; constexpr std::ptrdiff_t total_bits() const; auto operator<=>(const member_offset&) const = default; };		(since C++26)

The type member_offset represents the offset of a member or base class relative to its enclosing class.

Data members

Member definition	Description
std::ptrdiff_t bytes	represents the offset in bytes (public member object)
std::ptrdiff_t bits	represents the remaining bits in the offset (public member object)

Member functions

total_bits	returns bytes * CHAR_BIT + bits (public member function)
operator<=>	the comparison is defaulted (public member function)

offset_of (C++26)

returns the offset of a (member or base) subobject relative to its enclosing class (function)
