template<class OtherElementType, size_t OtherByteAlignment> constexpr aligned_accessor(aligned_accessor<OtherElementType, OtherByteAlignment>) noexcept;

Constraints:

• is_convertible_v<OtherElementType(*)[], element_type(*)[]>is true.
• OtherByteAlignment >= byte_alignment is true.

template<class OtherElementType> constexpr explicit aligned_accessor(default_accessor<OtherElementType>) noexcept;

Constraints: is_convertible_v<OtherElementType(*)[], element_type(*)[]>is true.

constexpr reference access(data_handle_type p, size_t i) const noexcept;

Preconditions: [0, i + 1) is an accessible range for p and *this.

Effects: Equivalent to: return assume_aligned<byte_alignment>(p)[i];

template<class OtherElementType> constexpr operator default_accessor<OtherElementType>() const noexcept;

Constraints: is_convertible_v<element_type(*)[], OtherElementType(*)[]>is true.

Effects: Equivalent to: return {};

constexpr typename offset_policy::data_handle_type offset(data_handle_type p, size_t i) const noexcept;

Preconditions: [0, i + 1) is an accessible range for p and *this.

Effects: Equivalent to: return assume_aligned<byte_alignment>(p) + i;
