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)

See More

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

Data members

Member name	Definition
bytes	represents the offset in bytes
bits	represents the remaining bits in the offset

Member functions

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

Example

See also

offset_of (C++26)

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