std::default_accessor - cppreference.com

template< class ElementType > class default_accessor;

(since C++23)

A specialization of 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 TriviallyCopyable.

[edit] Template parameters ElementType - the element type. Shall be a complete object type that is neither an abstract class type nor an array type. Otherwise, the program is ill-formed [edit] Member types Member type Definition offset_policy default_accessor element_type ElementType reference ElementType& data_handle_type ElementType* [edit] Member functions constructs a default_accessor
(public member function) returns a n^th element provided by arguments

constexpr default_accessor() noexcept = default;

(1)

template< class OtherElementType > constexpr default_accessor( default_accessor<OtherElementType> ) noexcept {}

(2)

1) Default constructs a default_accessor.

2)

Constructs a

default_accessor

from

default_accessor<OtherElementType>

. The constructor has no visible effect. This overload participates in overload 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;.
