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 AccessorPol-
       icy used	by
	  std::mdspan if no user-specified accessor policy is provided.

	  Each	specialization	of  default_accessor models semiregular	and is
       TriviallyCopyable.

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
       program 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
       arguments
			(public	member function)

       std::default_accessor::default_accessor

	  constexpr	 default_accessor()	 noexcept      =      default;
       (1)
	  template<		class		 OtherElementType	     >
       (2)
	  constexpr  default_accessor(	default_accessor<OtherElementType>   )
       noexcept	{}

	  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
       overload	resolution
	  only	  if	 std::is_convertible_v<OtherElementType(*)[],	  ele-
       ment_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;.
