std::default_accessor(3) C++ Standard Libary std::default_accessor(3) NAME std::default_accessor - std::default_accessor Synopsis Defined in header <mdspan> template< class ElementType > (since C++23) class default_accessor; The std::default_accessor class template is the default AccessorPolicy used by std::mdspan if no user-specified accessor policy is provided. Each specialization of default_accessor models semiregular and is Triv- iallyCopyable. Template parameters the element type. Shall be a complete object type that is neither an ElementType - abstract class type nor an array type. Otherwise, the pro- gram is ill-formed Member types Member type Definition offset_policy default_accessor element_type ElementType reference ElementType& data_handle_type ElementType* Member functions constructor constructs a default_accessor (public member function) access returns a n^th element provided by arguments (public member function) offset returns a data handle that has an offset provided by argu- ments (public member function) std::default_accessor::default_accessor constexpr default_accessor() noexcept = default; (1) template< class OtherElementType > (2) constexpr default_accessor( default_accessor<OtherElementType> ) noex- cept {} 1) Default constructs a default_accessor. 2) Constructs a default_accessor from default_accessor<OtherElement- Type>. The constructor has no visible effect. This overload participates in over- load resolution only if std::is_convertible_v<OtherElementType(*)[], element_type(*)[]> is true. std::default_accessor::access constexpr reference access( data_handle_type p, std::size_t i ) const noexcept; Equivalent to return p[i];. std::default_accessor::offset constexpr data_handle_type offset( data_handle_type p, std::size_t i ) const noexcept; Equivalent to return p + i;.
